In this example, `cb` will do nothing other -than insure the once-and-only-once, asynchronous invocation of the callback. - - doAsync(cb(function(err, res) { - console.log(res); - })); - -### Timeout Handling - -Timeouts are specified through the `.timeout()` method, and are specified in milliseconds.

If an 'errback' handler has been provided to `.error()`, then it is assumed that the error-first parameter -to the success handler is no longer required. To illustrate, - - doAsync(cb(function(err, res) { - if (err) { - console.error(err); - } else { - console.log(res); - } - })); - -Can be rewritten as: - - doAsync(cb(console.log).error(console.error)); - -### Force Once-and-only-once Callback Execution - -Sometimes it's necessary to ensure that a callback is invoked once, and no more. Once-and-only-once execution semantics can be -enforced by using `.once()`. - - function runTwice(callback) { - process.nextTick(function() { - callback(); - callback(); - }); - } - - runTwice(cb(function() { - console.log('I will only run once'); - }).once()); - -*Note: technically, `.once()` simply enforces at-most-once semantics. However, when combined with `.timeout()`, once-and-only-once -is achieved.* - -### Combining Features - -The `cb` API is fully chainable, and any arrangement of the features is valid.

If your app uses only one database, you should use `mongose.connect`. If you need to create additional connections, use `mongoose.createConnection`. +First, we need to define a connection. If your app uses only one database, you should use `mongoose.connect`. If you need to create additional connections, use `mongoose.createConnection`. Both `connect` and `createConnection` take a `mongodb://` URI, or the parameters `host, database, port, options`. - var mongoose = require('mongoose'); +```js +var mongoose = require('mongoose'); - mongoose.connect('mongodb://localhost/my_database'); +mongoose.connect('mongodb://localhost/my_database'); +``` Once connected, the `open` event is fired on the `Connection` instance. If you're using `mongoose.connect`, the `Connection` is `mongoose.connection`. Otherwise, `mongoose.createConnection` return value is a `Connection`. +**Note:** _If the local connection fails then try using 127.0.0.1 instead of localhost. Sometimes issues may arise when the local hostname has been changed._ + **Important!** Mongoose buffers all the commands until it's connected to the database. This means that you don't have to wait until it connects to MongoDB in order to define models, run queries, etc. ### Defining a Model -Models are defined through the `Schema` interface. +Models are defined through the `Schema` interface. - var Schema = mongoose.Schema - , ObjectId = Schema.ObjectId; +```js +var Schema = mongoose.Schema, + ObjectId = Schema.ObjectId; - var BlogPost = new Schema({ - author : ObjectId - , title : String - , body : String - , date : Date - }); +var BlogPost = new Schema({ + author : ObjectId, + title : String, + body : String, + date : Date +}); +``` Aside from defining the structure of your documents and the types of data you're storing, a Schema handles the definition of: @@ -80,24 +95,26 @@ Aside from defining the structure of your documents and the types of data you're The following example shows some of these features: - var Comment = new Schema({ - name : { type: String, default: 'hahaha' } - , age : { type: Number, min: 18, index: true } - , bio : { type: String, match: /[a-z]/ } - , date : { type: Date, default: Date.now } - , buff : Buffer - }); - - // a setter - Comment.path('name').set(function (v) { - return capitalize(v); - }); - - // middleware - Comment.pre('save', function (next) { - notify(this.get('email')); - next(); - }); +```js +var Comment = new Schema({ + name: { type: String, default: 'hahaha' }, + age: { type: Number, min: 18, index: true }, + bio: { type: String, match: /[a-z]/ }, + date: { type: Date, default: Date.now }, + buff: Buffer +}); + +// a setter +Comment.path('name').set(function (v) { + return capitalize(v); +}); + +// middleware +Comment.pre('save', function (next) { + notify(this.get('email')); + next(); +}); +``` Take a look at the example in `examples/schema.js` for an end-to-end example of a typical setup. @@ -105,77 +122,102 @@ Take a look at the example in `examples/schema.js` for an end-to-end example of Once we define a model through `mongoose.model('ModelName', mySchema)`, we can access it through the same function - var myModel = mongoose.model('ModelName'); +```js +var myModel = mongoose.model('ModelName'); +``` Or just do it all at once - var MyModel = mongoose.model('ModelName', mySchema); +```js +var MyModel = mongoose.model('ModelName', mySchema); +``` -We can then instantiate it, and save it: +The first argument is the _singular_ name of the collection your model is for. **Mongoose automatically looks for the _plural_ version of your model name.** For example, if you use - var instance = new MyModel(); - instance.my.key = 'hello'; - instance.save(function (err) { - // - }); +```js +var MyModel = mongoose.model('Ticket', mySchema); +``` + +Then Mongoose will create the model for your __tickets__ collection, not your __ticket__ collection. + +Once we have our model, we can then instantiate it, and save it: + +```js +var instance = new MyModel(); +instance.my.key = 'hello'; +instance.save(function (err) { + // +}); +``` Or we can find documents from the same collection - MyModel.find({}, function (err, docs) { - // docs.forEach - }); +```js +MyModel.find({}, function (err, docs) { + // docs.forEach +}); +``` You can also `findOne`, `findById`, `update`, etc. For more details check out [the docs](http://mongoosejs.com/docs/queries.html). **Important!** If you opened a separate connection using `mongoose.createConnection()` but attempt to access the model through `mongoose.model('ModelName')` it will not work as expected since it is not hooked up to an active db connection.

This module aims to be comprehensive, so if you feel anything is +missing please create a GitHub issue for it. + +## Common Pitfalls [(StackOverflow)](http://stackoverflow.com/questions/tagged/async.js) +### Synchronous iteration functions + +If you get an error like `RangeError: Maximum call stack size exceeded.` or other stack overflow issues when using async, you are likely using a synchronous iterator. By *synchronous* we mean a function that calls its callback on the same tick in the javascript event loop, without doing any I/O or using any timers. Calling many callbacks iteratively will quickly overflow the stack. If you run into this issue, just defer your callback with `async.setImmediate` to start a new call stack on the next tick of the event loop. + +This can also arise by accident if you callback early in certain cases: + +```js +async.eachSeries(hugeArray, function iterator(item, callback) { + if (inCache(item)) { + callback(null, cache[item]); // if many items are cached, you'll overflow + } else { + doSomeIO(item, callback); + } +}, function done() { + //... +}); +``` + +Just change it to: + +```js +async.eachSeries(hugeArray, function iterator(item, callback) { + if (inCache(item)) { + async.setImmediate(function () { + callback(null, cache[item]); + }); + } else { + doSomeIO(item, callback); + //... +``` + +Async guards against synchronous functions in some, but not all, cases. If you are still running into stack overflows, you can defer as suggested above, or wrap functions with [`async.ensureAsync`](#ensureAsync) Functions that are asynchronous by their nature do not have this problem and don't need the extra callback deferral. + +If JavaScript's event loop is still a bit nebulous, check out [this article](http://blog.carbonfive.com/2013/10/27/the-javascript-event-loop-explained/) or [this talk](http://2014.jsconf.eu/speakers/philip-roberts-what-the-heck-is-the-event-loop-anyway.html) for more detailed information about how it works. + + +### Multiple callbacks + +Make sure to always `return` when calling a callback early, otherwise you will cause multiple callbacks and unpredictable behavior in many cases. + +```js +async.waterfall([ + function (callback) { + getSomething(options, function (err, result) { + if (err) { + callback(new Error("failed getting something:" + err.message)); + // we should return here + } + // since we did not return, this callback still will be called and + // `processData` will be called twice + callback(null, result); + }); + }, + processData +], done) +``` + +It is always good practice to `return callback(err, result)` whenever a callback call is not the last statement of a function. + + +### Binding a context to an iterator + +This section is really about `bind`, not about `async`. If you are wondering how to +make `async` execute your iterators in a given context, or are confused as to why +a method of another library isn't working as an iterator, study this example: + +```js +// Here is a simple object with an (unnecessarily roundabout) squaring method +var AsyncSquaringLibrary = { + squareExponent: 2, + square: function(number, callback){ + var result = Math.pow(number, this.squareExponent); + setTimeout(function(){ + callback(null, result); + }, 200); + } +}; + +async.map([1, 2, 3], AsyncSquaringLibrary.square, function(err, result){ + // result is [NaN, NaN, NaN] + // This fails because the `this.squareExponent` expression in the square + // function is not evaluated in the context of AsyncSquaringLibrary, and is + // therefore undefined. +}); + +async.map([1, 2, 3], AsyncSquaringLibrary.square.bind(AsyncSquaringLibrary), function(err, result){ + // result is [1, 4, 9] + // With the help of bind we can attach a context to the iterator before + // passing it to async. Now the square function will be executed in its + // 'home' AsyncSquaringLibrary context and the value of `this.squareExponent` + // will be as expected. +}); +``` + +## Download + +The source is available for download from +[GitHub](https://github.com/caolan/async/blob/master/lib/async.js). +Alternatively, you can install using Node Package Manager (`npm`): + + npm install async + +As well as using Bower: + + bower install async + +__Development:__ [async.js](https://github.com/caolan/async/raw/master/lib/async.js) - 29.6kb Uncompressed + +## In the Browser + +So far it's been tested in IE6, IE7, IE8, FF3.6 and Chrome 5. + +Usage: + +```html + + +``` + +## Documentation + +Some functions are also available in the following forms: +* `Series` - the same as `` but runs only a single async operation at a time +* `Limit` - the same as `` but runs a maximum of `limit` async operations at a time + +### Collections + +* [`each`](#each), `eachSeries`, `eachLimit` +* [`forEachOf`](#forEachOf), `forEachOfSeries`, `forEachOfLimit` +* [`map`](#map), `mapSeries`, `mapLimit` +* [`filter`](#filter), `filterSeries`, `filterLimit` +* [`reject`](#reject), `rejectSeries`, `rejectLimit` +* [`reduce`](#reduce), [`reduceRight`](#reduceRight) +* [`detect`](#detect), `detectSeries`, `detectLimit` +* [`sortBy`](#sortBy) +* [`some`](#some), `someLimit` +* [`every`](#every), `everyLimit` +* [`concat`](#concat), `concatSeries` + +### Control Flow + +* [`series`](#seriestasks-callback) +* [`parallel`](#parallel), `parallelLimit` +* [`whilst`](#whilst), [`doWhilst`](#doWhilst) +* [`until`](#until), [`doUntil`](#doUntil) +* [`during`](#during), [`doDuring`](#doDuring) +* [`forever`](#forever) +* [`waterfall`](#waterfall) +* [`compose`](#compose) +* [`seq`](#seq) +* [`applyEach`](#applyEach), `applyEachSeries` +* [`queue`](#queue), [`priorityQueue`](#priorityQueue) +* [`cargo`](#cargo) +* [`auto`](#auto) +* [`retry`](#retry) +* [`iterator`](#iterator) +* [`times`](#times), `timesSeries`, `timesLimit` + +### Utils + +* [`apply`](#apply) +* [`nextTick`](#nextTick) +* [`memoize`](#memoize) +* [`unmemoize`](#unmemoize) +* [`ensureAsync`](#ensureAsync) +* [`constant`](#constant) +* [`asyncify`](#asyncify) +* [`wrapSync`](#wrapSync) +* [`log`](#log) +* [`dir`](#dir) +* [`noConflict`](#noConflict) + +## Collections + + + +### each(arr, iterator, [callback]) + +Applies the function `iterator` to each item in `arr`, in parallel. +The `iterator` is called with an item from the list, and a callback for when it +has finished.

The respective callback is used for every task in the list. +* `saturated` - A callback that is called when the `queue.length()` hits the concurrency and further tasks will be queued. +* `empty` - A callback that is called when the last item from the `queue` is given to a `worker`. +* `drain` - A callback that is called when the last item from the `queue` has returned from the `worker`. +* `idle()`, `pause()`, `resume()`, `kill()` - cargo inherits all of the same methods and event calbacks as [`queue`](#queue) + +__Example__ + +```js +// create a cargo object with payload 2 + +var cargo = async.cargo(function (tasks, callback) { + for(var i=0; i +### auto(tasks, [concurrency], [callback]) + +Determines the best order for running the functions in `tasks`, based on their requirements. Each function can optionally depend on other functions being completed first, and each function is run as soon as its requirements are satisfied. + +If any of the functions pass an error to their callback, the `auto` sequence will stop. Further tasks will not execute (so any other functions depending on it will not run), and the main `callback` is immediately called with the error. Functions also receive an object containing the results of functions which have completed so far. + +Note, all functions are called with a `results` object as a second argument, +so it is unsafe to pass functions in the `tasks` object which cannot handle the +extra argument. + +For example, this snippet of code: + +```js +async.auto({ + readData: async.apply(fs.readFile, 'data.txt', 'utf-8') +}, callback); +``` + +will have the effect of calling `readFile` with the results object as the last +argument, which will fail: + +```js +fs.readFile('data.txt', 'utf-8', cb, {}); +``` + +Instead, wrap the call to `readFile` in a function which does not forward the +`results` object: + +```js +async.auto({ + readData: function(cb, results){ + fs.readFile('data.txt', 'utf-8', cb); + } +}, callback); +``` + +__Arguments__ + +* `tasks` - An object. Each of its properties is either a function or an array of + requirements, with the function itself the last item in the array. The object's key + of a property serves as the name of the task defined by that property, + i.e. can be used when specifying requirements for other tasks. + The function receives two arguments: (1) a `callback(err, result)` which must be + called when finished, passing an `error` (which can be `null`) and the result of + the function's execution, and (2) a `results` object, containing the results of + the previously executed functions. +* `concurrency` - An optional `integer` for determining the maximum number of tasks that can be run in parallel. By default, as many as possible. +* `callback(err, results)` - An optional callback which is called when all the + tasks have been completed. It receives the `err` argument if any `tasks` + pass an error to their callback. Results are always returned; however, if + an error occurs, no further `tasks` will be performed, and the results + object will only contain partial results. + + +__Example__ + +```js +async.auto({ + get_data: function(callback){ + console.log('in get_data'); + // async code to get some data + callback(null, 'data', 'converted to array'); + }, + make_folder: function(callback){ + console.log('in make_folder'); + // async code to create a directory to store a file in + // this is run at the same time as getting the data + callback(null, 'folder'); + }, + write_file: ['get_data', 'make_folder', function(callback, results){ + console.log('in write_file', JSON.stringify(results)); + // once there is some data and the directory exists, + // write the data to a file in the directory + callback(null, 'filename'); + }], + email_link: ['write_file', function(callback, results){ + console.log('in email_link', JSON.stringify(results)); + // once the file is written let's email a link to it... + // results.write_file contains the filename returned by write_file. + callback(null, {'file':results.write_file, 'email':'user@example.com'}); + }] +}, function(err, results) { + console.log('err = ', err); + console.log('results = ', results); +}); +``` + +This is a fairly trivial example, but to do this using the basic parallel and +series functions would look like this: + +```js +async.parallel([ + function(callback){ + console.log('in get_data'); + // async code to get some data + callback(null, 'data', 'converted to array'); + }, + function(callback){ + console.log('in make_folder'); + // async code to create a directory to store a file in + // this is run at the same time as getting the data + callback(null, 'folder'); + } +], +function(err, results){ + async.series([ + function(callback){ + console.log('in write_file', JSON.stringify(results)); + // once there is some data and the directory exists, + // write the data to a file in the directory + results.push('filename'); + callback(null); + }, + function(callback){ + console.log('in email_link', JSON.stringify(results)); + // once the file is written let's email a link to it... + callback(null, {'file':results.pop(), 'email':'user@example.com'}); + } + ]); +}); +``` + +For a complicated series of `async` tasks, using the [`auto`](#auto) function makes adding +new tasks much easier (and the code more readable). + + +--------------------------------------- + + +### retry([opts = {times: 5, interval: 0}| 5], task, [callback]) + +Attempts to get a successful response from `task` no more than `times` times before +returning an error. If the task is successful, the `callback` will be passed the result +of the successful task. If all attempts fail, the callback will be passed the error and +result (if any) of the final attempt. + +__Arguments__ + +* `opts` - Can be either an object with `times` and `interval` or a number. + * `times` - The number of attempts to make before giving up. The default is `5`. + * `interval` - The time to wait between retries, in milliseconds. The default is `0`. + * If `opts` is a number, the number specifies the number of times to retry, with the default interval of `0`. +* `task(callback, results)` - A function which receives two arguments: (1) a `callback(err, result)` + which must be called when finished, passing `err` (which can be `null`) and the `result` of + the function's execution, and (2) a `results` object, containing the results of + the previously executed functions (if nested inside another control flow). +* `callback(err, results)` - An optional callback which is called when the + task has succeeded, or after the final failed attempt. It receives the `err` and `result` arguments of the last attempt at completing the `task`. + +The [`retry`](#retry) function can be used as a stand-alone control flow by passing a callback, as shown below: + +```js +// try calling apiMethod 3 times +async.retry(3, apiMethod, function(err, result) { + // do something with the result +}); +``` + +```js +// try calling apiMethod 3 times, waiting 200 ms between each retry +async.retry({times: 3, interval: 200}, apiMethod, function(err, result) { + // do something with the result +}); +``` + +```js +// try calling apiMethod the default 5 times no delay between each retry +async.retry(apiMethod, function(err, result) { + // do something with the result +}); +``` + +It can also be embedded within other control flow functions to retry individual methods +that are not as reliable, like this: + +```js +async.auto({ + users: api.getUsers.bind(api), + payments: async.retry(3, api.getPayments.bind(api)) +}, function(err, results) { + // do something with the results +}); +``` + + +--------------------------------------- + + +### iterator(tasks) + +Creates an iterator function which calls the next function in the `tasks` array, +returning a continuation to call the next one after that. It's also possible to +“peek” at the next iterator with `iterator.next()`. + +This function is used internally by the `async` module, but can be useful when +you want to manually control the flow of functions in series. + +__Arguments__ + +* `tasks` - An array of functions to run. + +__Example__ + +```js +var iterator = async.iterator([ + function(){ sys.p('one'); }, + function(){ sys.p('two'); }, + function(){ sys.p('three'); } +]); + +node> var iterator2 = iterator(); +'one' +node> var iterator3 = iterator2(); +'two' +node> iterator3(); +'three' +node> var nextfn = iterator2.next(); +node> nextfn(); +'three' +``` + +--------------------------------------- + + +### apply(function, arguments..) + +Creates a continuation function with some arguments already applied. + +Useful as a shorthand when combined with other control flow functions. Any arguments +passed to the returned function are added to the arguments originally passed +to apply. + +__Arguments__ + +* `function` - The function you want to eventually apply all arguments to. +* `arguments...` - Any number of arguments to automatically apply when the + continuation is called. + +__Example__ + +```js +// using apply + +async.parallel([ + async.apply(fs.writeFile, 'testfile1', 'test1'), + async.apply(fs.writeFile, 'testfile2', 'test2'), +]); + + +// the same process without using apply + +async.parallel([ + function(callback){ + fs.writeFile('testfile1', 'test1', callback); + }, + function(callback){ + fs.writeFile('testfile2', 'test2', callback); + } +]); +``` + +It's possible to pass any number of additional arguments when calling the +continuation: + +```js +node> var fn = async.apply(sys.puts, 'one'); +node> fn('two', 'three'); +one +two +three +``` + +--------------------------------------- + + +### nextTick(callback), setImmediate(callback) + +Calls `callback` on a later loop around the event loop. In Node.js this just +calls `process.nextTick`; in the browser it falls back to `setImmediate(callback)` +if available, otherwise `setTimeout(callback, 0)`, which means other higher priority +events may precede the execution of `callback`. + +This is used internally for browser-compatibility purposes. + +__Arguments__ + +* `callback` - The function to call on a later loop around the event loop. + +__Example__ + +```js +var call_order = []; +async.nextTick(function(){ + call_order.push('two'); + // call_order now equals ['one','two'] +}); +call_order.push('one') +``` + + +### times(n, iterator, [callback]) + +Calls the `iterator` function `n` times, and accumulates results in the same manner +you would use with [`map`](#map). + +__Arguments__ + +* `n` - The number of times to run the function. +* `iterator` - The function to call `n` times. +* `callback` - see [`map`](#map) + +__Example__ + +```js +// Pretend this is some complicated async factory +var createUser = function(id, callback) { + callback(null, { + id: 'user' + id + }) +} +// generate 5 users +async.times(5, function(n, next){ + createUser(n, function(err, user) { + next(err, user) + }) +}, function(err, users) { + // we should now have 5 users +}); +``` + +__Related__ + +* timesSeries(n, iterator, [callback]) +* timesLimit(n, limit, iterator, [callback]) + + +## Utils + + +### memoize(fn, [hasher]) + +Caches the results of an `async` function. When creating a hash to store function +results against, the callback is omitted from the hash and an optional hash +function can be used. + +If no hash function is specified, the first argument is used as a hash key, which may work reasonably if it is a string or a data type that converts to a distinct string. Note that objects and arrays will not behave reasonably. Neither will cases where the other arguments are significant. In such cases, specify your own hash function. + +The cache of results is exposed as the `memo` property of the function returned +by `memoize`. + +__Arguments__ + +* `fn` - The function to proxy and cache results from. +* `hasher` - An optional function for generating a custom hash for storing + results. It has all the arguments applied to it apart from the callback, and + must be synchronous. + +__Example__ + +```js +var slow_fn = function (name, callback) { + // do something + callback(null, result); +}; +var fn = async.memoize(slow_fn); + +// fn can now be used as if it were slow_fn +fn('some name', function () { + // callback +}); +``` + + +### unmemoize(fn) + +Undoes a [`memoize`](#memoize)d function, reverting it to the original, unmemoized +form. Handy for testing. + +__Arguments__ + +* `fn` - the memoized function + +--------------------------------------- + + +### ensureAsync(fn) + +Wrap an async function and ensure it calls its callback on a later tick of the event loop. If the function already calls its callback on a next tick, no extra deferral is added. This is useful for preventing stack overflows (`RangeError: Maximum call stack size exceeded`) and generally keeping [Zalgo](http://blog.izs.me/post/59142742143/designing-apis-for-asynchrony) contained. + +__Arguments__ + +* `fn` - an async function, one that expects a node-style callback as its last argument + +Returns a wrapped function with the exact same call signature as the function passed in. + +__Example__ + +```js +function sometimesAsync(arg, callback) { + if (cache[arg]) { + return callback(null, cache[arg]); // this would be synchronous!! + } else { + doSomeIO(arg, callback); // this IO would be asynchronous + } +} + +// this has a risk of stack overflows if many results are cached in a row +async.mapSeries(args, sometimesAsync, done); + +// this will defer sometimesAsync's callback if necessary, +// preventing stack overflows +async.mapSeries(args, async.ensureAsync(sometimesAsync), done); + +``` + +--------------------------------------- + + +### constant(values...) + +Returns a function that when called, calls-back with the values provided. Useful as the first function in a `waterfall`, or for plugging values in to `auto`. + +__Example__ + +```js +async.waterfall([ + async.constant(42), + function (value, next) { + // value === 42 + }, + //... +], callback); + +async.waterfall([ + async.constant(filename, "utf8"), + fs.readFile, + function (fileData, next) { + //... + } + //... +], callback); + +async.auto({ + hostname: async.constant("https://server.net/"), + port: findFreePort, + launchServer: ["hostname", "port", function (cb, options) { + startServer(options, cb); + }], + //... +}, callback); + +``` + +--------------------------------------- + + + +### asyncify(func) + +__Alias:__ `wrapSync` + +Take a sync function and make it async, passing its return value to a callback. This is useful for plugging sync functions into a waterfall, series, or other async functions. Any arguments passed to the generated function will be passed to the wrapped function (except for the final callback argument). Errors thrown will be passed to the callback. + +__Example__ + +```js +async.waterfall([ + async.apply(fs.readFile, filename, "utf8"), + async.asyncify(JSON.parse), + function (data, next) { + // data is the result of parsing the text. + // If there was a parsing error, it would have been caught. + } +], callback) +``` + +If the function passed to `asyncify` returns a Promise, that promises's resolved/rejected state will be used to call the callback, rather than simply the synchronous return value. Example: + +```js +async.waterfall([ + async.apply(fs.readFile, filename, "utf8"), + async.asyncify(function (contents) { + return db.model.create(contents); + }), + function (model, next) { + // `model` is the instantiated model object. + // If there was an error, this function would be skipped. + } +], callback) +``` + +This also means you can asyncify ES2016 `async` functions. + +```js +var q = async.queue(async.asyncify(async function (file) { + var intermediateStep = await processFile(file); + return await somePromise(intermediateStep) +})); + +q.push(files); +``` + +--------------------------------------- + + +### log(function, arguments) + +Logs the result of an `async` function to the `console`.

For example, what if someone does not want to do background\njob creation after the logical save? \n\nIt is nicer to tack on functionality using what we call `pre` and `post` hooks. These\nare functions that you define and that you direct to execute before or after particular\nmethods.\n\n## Example\nWe can use `hooks` to add validation and background jobs in the following way:\n\n var hooks = require('hooks')\n , Document = require('./path/to/some/document/constructor');\n\n // Add hooks' methods: `hook`, `pre`, and `post` \n for (var k in hooks) {\n Document[k] = hooks[k];\n }\n\n // Define a new method that is able to invoke pre and post middleware\n Document.hook('save', Document.prototype.save);\n\n // Define a middleware function to be invoked before 'save'\n Document.pre('save', function validate (next) {\n // The `this` context inside of `pre` and `post` functions\n // is the Document instance\n if (this.isValid()) next(); // next() passes control to the next middleware\n // or to the target method itself\n else next(new Error(\"Invalid\")); // next(error) invokes an error callback\n });\n\n // Define a middleware function to be invoked after 'save'\n Document.post('save', function createJob () {\n this.sendToBackgroundQueue();\n });\n\nIf you already have defined `Document.prototype` methods for which you want pres and posts,\nthen you do not need to explicitly invoke `Document.hook(...)`. Invoking `Document.pre(methodName, fn)`\nor `Document.post(methodName, fn)` will automatically and lazily change `Document.prototype[methodName]`\nso that it plays well with `hooks`. An equivalent way to implement the previous example is:\n\n```javascript\nvar hooks = require('hooks')\n , Document = require('./path/to/some/document/constructor');\n\n// Add hooks' methods: `hook`, `pre`, and `post` \nfor (var k in hooks) {\n Document[k] = hooks[k];\n}\n\nDocument.prototype.save = function () {\n // ...\n};\n\n// Define a middleware function to be invoked before 'save'\nDocument.pre('save', function validate (next) {\n // The `this` context inside of `pre` and `post` functions\n // is the Document instance\n if (this.isValid()) next(); // next() passes control to the next middleware\n // or to the target method itself\n else next(new Error(\"Invalid\")); // next(error) invokes an error callback\n});\n\n// Define a middleware function to be invoked after 'save'\nDocument.post('save', function createJob () {\n this.sendToBackgroundQueue();\n});\n```\n\n## Pres and Posts as Middleware\nWe structure pres and posts as middleware to give you maximum flexibility:\n\n1. You can define **multiple** pres (or posts) for a single method.\n2. These pres (or posts) are then executed as a chain of methods.\n3. Any functions in this middleware chain can choose to halt the chain's execution by `next`ing an Error from that middleware function. If this occurs, then none of the other middleware in the chain will execute, and the main method (e.g., `save`) will not execute. This is nice, for example, when we don't want a document to save if it is invalid.\n\n## Defining multiple pres (or posts)\n`pre` is chainable, so you can define multiple pres via:\n Document.pre('save', function (next, halt) {\n console.log(\"hello\");\n }).pre('save', function (next, halt) {\n console.log(\"world\");\n });\n\nAs soon as one pre finishes executing, the next one will be invoked, and so on.\n\n## Error Handling\nYou can define a default error handler by passing a 2nd function as the 3rd argument to `hook`:\n Document.hook('set', function (path, val) {\n this[path] = val;\n }, function (err) {\n // Handler the error here\n console.error(err);\n });\n\nThen, we can pass errors to this handler from a pre or post middleware function:\n Document.pre('set', function (next, path, val) {\n next(new Error());\n });\n\nIf you do not set up a default handler, then `hooks` makes the default handler that just throws the `Error`.\n\nThe default error handler can be over-rided on a per method invocation basis.\n\nIf the main method that you are surrounding with pre and post middleware expects its last argument to be a function\nwith callback signature `function (error, ...)`, then that callback becomes the error handler, over-riding the default\nerror handler you may have set up.\n \n```javascript\nDocument.hook('save', function (callback) {\n // Save logic goes here\n ...\n});\n\nvar doc = new Document();\ndoc.save( function (err, saved) {\n // We can pass err via `next` in any of our pre or post middleware functions\n if (err) console.error(err);\n \n // Rest of callback logic follows ...\n});\n```\n\n## Mutating Arguments via Middleware\n`pre` and `post` middleware can also accept the intended arguments for the method\nthey augment. This is useful if you want to mutate the arguments before passing\nthem along to the next middleware and eventually pass a mutated arguments list to\nthe main method itself.\n\nAs a simple example, let's define a method `set` that just sets a key, value pair.\nIf we want to namespace the key, we can do so by adding a `pre` middleware hook\nthat runs before `set`, alters the arguments by namespacing the `key` argument, and passes them onto `set`:\n\n Document.hook('set', function (key, val) {\n this[key] = val;\n });\n Document.pre('set', function (next, key, val) {\n next('namespace-' + key, val);\n });\n var doc = new Document();\n doc.set('hello', 'world');\n console.log(doc.hello); // undefined\n console.log(doc['namespace-hello']); // 'world'\n\nAs you can see above, we pass arguments via `next`.\n\nIf you are not mutating the arguments, then you can pass zero arguments\nto `next`, and the next middleware function will still have access\nto the arguments.\n\n Document.hook('set', function (key, val) {\n this[key] = val;\n });\n Document.pre('set', function (next, key, val) {\n // I have access to key and val here\n next(); // We don't need to pass anything to next\n });\n Document.pre('set', function (next, key, val) {\n // And I still have access to the original key and val here\n next();\n });\n\nFinally, you can add arguments that downstream middleware can also see:\n\n // Note that in the definition of `set`, there is no 3rd argument, options\n Document.hook('set', function (key, val) {\n // But...\n var options = arguments[2]; // ...I have access to an options argument\n // because of pre function pre2 (defined below)\n console.log(options); // '{debug: true}'\n this[key] = val;\n });\n Document.pre('set', function pre1 (next, key, val) {\n // I only have access to key and val arguments\n console.log(arguments.length); // 3\n next(key, val, {debug: true});\n });\n Document.pre('set', function pre2 (next, key, val, options) {\n console.log(arguments.length); // 4\n console.log(options); // '{ debug: true}'\n next();\n });\n Document.pre('set', function pre3 (next, key, val, options) {\n // I still have access to key, val, AND the options argument introduced via the preceding middleware\n console.log(arguments.length); // 4\n console.log(options); // '{ debug: true}'\n next();\n });\n \n var doc = new Document()\n doc.set('hey', 'there');\n\n## Parallel `pre` middleware\n\nAll middleware up to this point has been \"serial\" middleware -- i.e., middleware whose logic\nis executed as a serial chain.\n\nSome scenarios call for parallel middleware -- i.e., middleware that can wait for several\nasynchronous services at once to respond.\n\nFor instance, you may only want to save a Document only after you have checked\nthat the Document is valid according to two different remote services.\n\nWe accomplish asynchronous middleware by adding a second kind of flow control callback\n(the only flow control callback so far has been `next`), called `done`.\n\n- `next` passes control to the next middleware in the chain\n- `done` keeps track of how many parallel middleware have invoked `done` and passes\n control to the target method when ALL parallel middleware have invoked `done`. If\n you pass an `Error` to `done`, then the error is handled, and the main method that is\n wrapped by pres and posts will not get invoked.\n\nWe declare pre middleware that is parallel by passing a 3rd boolean argument to our `pre`\ndefinition method.\n\nWe illustrate via the parallel validation example mentioned above:\n\n Document.hook('save', function targetFn (callback) {\n // Save logic goes here\n // ...\n // This only gets run once the two `done`s are both invoked via preOne and preTwo.\n });\n\n // true marks this as parallel middleware\n Document.pre('save', true, function preOne (next, doneOne, callback) {\n remoteServiceOne.validate(this.serialize(), function (err, isValid) {\n // The code in here will probably be run after the `next` below this block\n // and could possibly be run after the console.log(\"Hola\") in `preTwo\n if (err) return doneOne(err);\n if (isValid) doneOne();\n });\n next(); // Pass control to the next middleware\n });\n \n // We will suppose that we need 2 different remote services to validate our document\n Document.pre('save', true, function preTwo (next, doneTwo, callback) {\n remoteServiceTwo.validate(this.serialize(), function (err, isValid) {\n if (err) return doneTwo(err);\n if (isValid) doneTwo();\n });\n next();\n });\n \n // While preOne and preTwo are parallel, preThree is a serial pre middleware\n Document.pre('save', function preThree (next, callback) {\n next();\n });\n \n var doc = new Document();\n doc.save( function (err, doc) {\n // Do stuff with the saved doc here...\n });\n\nIn the above example, flow control may happen in the following way:\n\n(1) doc.save -> (2) preOne --(next)--> (3) preTwo --(next)--> (4) preThree --(next)--> (wait for dones to invoke) -> (5) doneTwo -> (6) doneOne -> (7) targetFn\n\nSo what's happening is that:\n\n1. You call `doc.save(...)`\n2. First, your preOne middleware gets executed. It makes a remote call to the validation service and `next()`s to the preTwo middleware.\n3. Now, your preTwo middleware gets executed. It makes a remote call to another validation service and `next()`s to the preThree middleware.\n4. Your preThree middleware gets executed. It immediately `next()`s. But nothing else gets executing until both `doneOne` and `doneTwo` are invoked inside the callbacks handling the response from the two valiation services.\n5. We will suppose that validation remoteServiceTwo returns a response to us first. In this case, we call `doneTwo` inside the callback to remoteServiceTwo.\n6. Some fractions of a second later, remoteServiceOne returns a response to us. In this case, we call `doneOne` inside the callback to remoteServiceOne.\n7. `hooks` implementation keeps track of how many parallel middleware has been defined per target function. It detects that both asynchronous pre middlewares (`preOne` and `preTwo`) have finally called their `done` functions (`doneOne` and `doneTwo`), so the implementation finally invokes our `targetFn` (i.e., our core `save` business logic).\n\n## Removing Pres\n\nYou can remove a particular pre associated with a hook:\n\n Document.pre('set', someFn);\n Document.removePre('set', someFn);\n\nAnd you can also remove all pres associated with a hook:\n Document.removePre('set'); // Removes all declared `pre`s on the hook 'set'\n\n## Tests\nTo run the tests:\n make test\n\n### Contributors\n- [Brian Noguchi](https://github.com/bnoguchi)\n\n### License\nMIT License\n\n---\n### Author\nBrian Noguchi\n", - "maintainers": [ - { - "name": "bnoguchi", - "email": "brian.noguchi@gmail.com" - } - ], - "_shasum": "0f591b1b344bdcb3df59773f62fbbaf85bf4028b", - "_resolved": "https://registry.npmjs.org/hooks/-/hooks-0.2.1.tgz", - "_from": "hooks@0.2.1", - "bugs": { - "url": "https://github.com/bnoguchi/hooks-js/issues" - } -} diff --git a/node_modules/mongoose/node_modules/kareem/.npmignore b/node_modules/mongoose/node_modules/kareem/.npmignore new file mode 100644 index 0000000..59d842b --- /dev/null +++ b/node_modules/mongoose/node_modules/kareem/.npmignore @@ -0,0 +1,28 @@ +# Logs +logs +*.log + +# Runtime data +pids +*.pid +*.seed + +# Directory for instrumented libs generated by jscoverage/JSCover +lib-cov + +# Coverage directory used by tools like istanbul +coverage + +# Grunt intermediate storage (http://gruntjs.com/creating-plugins#storing-task-files) +.grunt + +# Compiled binary addons (http://nodejs.org/api/addons.html) +build/Release + +# Dependency directory +# Commenting this out is preferred by some people, see +# https://www.npmjs.org/doc/misc/npm-faq.html#should-i-check-my-node_modules-folder-into-git- +node_modules + +# Users Environment Variables +.lock-wscript diff --git a/node_modules/mongoose/node_modules/kareem/.travis.yml b/node_modules/mongoose/node_modules/kareem/.travis.yml new file mode 100644 index 0000000..117c2b6 --- /dev/null +++ b/node_modules/mongoose/node_modules/kareem/.travis.yml @@ -0,0 +1,9 @@ +language: node_js +node_js: + - "5" + - "4" + - "0.12" + - "0.10" + - "iojs" +script: "npm run-script test-travis" +after_script: "npm install coveralls@2.10.0 && cat ./coverage/lcov.info | coveralls" diff --git a/node_modules/mongoose/node_modules/kareem/LICENSE b/node_modules/mongoose/node_modules/kareem/LICENSE new file mode 100644 index 0000000..e06d208 --- /dev/null +++ b/node_modules/mongoose/node_modules/kareem/LICENSE @@ -0,0 +1,202 @@ +Apache License + Version 2.0, January 2004 + http://www.apache.org/licenses/ + + TERMS AND CONDITIONS FOR USE, REPRODUCTION, AND DISTRIBUTION + + 1.

ObjectIDs can be represented as 24-digit hexadecimal strings, but you must convert the string back into an ObjectID before you can use it in the database. For example: - -```javascript - // Get the objectID type - var ObjectID = require('mongodb').ObjectID; - - var idString = '4e4e1638c85e808431000003'; - collection.findOne({_id: new ObjectID(idString)}, console.log) // ok - collection.findOne({_id: idString}, console.log) // wrong! callback gets undefined -``` - -Here are the constructors the non-Javascript BSON primitive types: - -```javascript - // Fetch the library - var mongo = require('mongodb'); - // Create new instances of BSON types - new mongo.Long(numberString) - new mongo.ObjectID(hexString) - new mongo.Timestamp() // the actual unique number is generated on insert. - new mongo.DBRef(collectionName, id, dbName) - new mongo.Binary(buffer) // takes a string or Buffer - new mongo.Code(code, [context]) - new mongo.Symbol(string) - new mongo.MinKey() - new mongo.MaxKey() - new mongo.Double(number) // Force double storage -``` - -The C/C++ bson parser/serializer --------------------------------- - -If you are running a version of this library has the C/C++ parser compiled, to enable the driver to use the C/C++ bson parser pass it the option native_parser:true like below - -```javascript - // using native_parser: - MongoClient.connect('mongodb://127.0.0.1:27017/test' - , {db: {native_parser: true}}, function(err, db) {}) -``` - -The C++ parser uses the js objects both for serialization and deserialization. - -GitHub information -================== - -The source code is available at http://github.com/mongodb/node-mongodb-native. -You can either clone the repository or download a tarball of the latest release. - -Once you have the source you can test the driver by running - - $ make test - -in the main directory.

A Cursor lazily uses the connection the first time -you call `nextObject`, `each`, or `toArray`. - -The basic operation on a cursor is the `nextObject` method -that fetches the next matching document from the database. The convenience -methods `each` and `toArray` call `nextObject` until the cursor is exhausted. - -Signatures: - -```javascript - var cursor = collection.find(query, [fields], options); - cursor.sort(fields).limit(n).skip(m). - - cursor.nextObject(function(err, doc) {}); - cursor.each(function(err, doc) {}); - cursor.toArray(function(err, docs) {}); - - cursor.rewind() // reset the cursor to its initial state. -``` - -Useful chainable methods of cursor. These can optionally be options of `find` instead of method calls: - - * `.limit(n).skip(m)` to control paging. - * `.sort(fields)` Order by the given fields. There are several equivalent syntaxes: - * `.sort({field1: -1, field2: 1})` descending by field1, then ascending by field2. - * `.sort([['field1', 'desc'], ['field2', 'asc']])` same as above - * `.sort([['field1', 'desc'], 'field2'])` same as above - * `.sort('field1')` ascending by field1 - -Other options of `find`: - -* `fields` the fields to fetch (to avoid transferring the entire document) -* `tailable` if true, makes the cursor [tailable](http://www.mongodb.org/display/DOCS/Tailable+Cursors). -* `batchSize` The number of the subset of results to request the database -to return for every request. This should initially be greater than 1 otherwise -the database will automatically close the cursor. The batch size can be set to 1 -with `batchSize(n, function(err){})` after performing the initial query to the database. -* `hint` See [Optimization: hint](http://www.mongodb.org/display/DOCS/Optimization#Optimization-Hint). -* `explain` turns this into an explain query. You can also call -`explain()` on any cursor to fetch the explanation. -* `snapshot` prevents documents that are updated while the query is active -from being returned multiple times. See more -[details about query snapshots](http://www.mongodb.org/display/DOCS/How+to+do+Snapshotted+Queries+in+the+Mongo+Database). -* `timeout` if false, asks MongoDb not to time out this cursor after an -inactivity period. - - -For information on how to create queries, see the -[MongoDB section on querying](http://www.mongodb.org/display/DOCS/Querying). - -```javascript - var MongoClient = require('mongodb').MongoClient - , format = require('util').format; - - MongoClient.connect('mongodb://127.0.0.1:27017/test', function(err, db) { - if(err) throw err; - - var collection = db - .collection('test') - .find({}) - .limit(10) - .toArray(function(err, docs) { - console.dir(docs); - }); - }); -``` - -Insert ------- - -Signature: - -```javascript - collection.insert(docs, options, [callback]); -``` - -where `docs` can be a single document or an array of documents. - -Useful options: - -* `safe:true` Should always set if you have a callback. - -See also: [MongoDB docs for insert](http://www.mongodb.org/display/DOCS/Inserting). - -```javascript - var MongoClient = require('mongodb').MongoClient - , format = require('util').format; - - MongoClient.connect('mongodb://127.0.0.1:27017/test', function(err, db) { - if(err) throw err; - - db.collection('test').insert({hello: 'world'}, {w:1}, function(err, objects) { - if (err) console.warn(err.message); - if (err && err.message.indexOf('E11000 ') !== -1) { - // this _id was already inserted in the database - } - }); - }); -``` - -Note that there's no reason to pass a callback to the insert or update commands -unless you use the `safe:true` option. If you don't specify `safe:true`, then -your callback will be called immediately. - -Update; update and insert (upsert) ----------------------------------- - -The update operation will update the first document that matches your query -(or all documents that match if you use `multi:true`). -If `safe:true`, `upsert` is not set, and no documents match, your callback will return 0 documents updated. - -See the [MongoDB docs](http://www.mongodb.org/display/DOCS/Updating) for -the modifier (`$inc`, `$set`, `$push`, etc.) formats. - -Signature: - -```javascript - collection.update(criteria, objNew, options, [callback]); -``` - -Useful options: - -* `safe:true` Should always set if you have a callback. -* `multi:true` If set, all matching documents are updated, not just the first. -* `upsert:true` Atomically inserts the document if no documents matched. - -Example for `update`: - -```javascript - var MongoClient = require('mongodb').MongoClient - , format = require('util').format; - - MongoClient.connect('mongodb://127.0.0.1:27017/test', function(err, db) { - if(err) throw err; - - db.collection('test').update({hi: 'here'}, {$set: {hi: 'there'}}, {w:1}, function(err) { - if (err) console.warn(err.message); - else console.log('successfully updated'); - }); - }); -``` - -Find and modify ---------------- - -`findAndModify` is like `update`, but it also gives the updated document to -your callback. But there are a few key differences between findAndModify and -update: - - 1. The signatures differ. - 2. You can only findAndModify a single item, not multiple items. - -Signature: - -```javascript - collection.findAndModify(query, sort, update, options, callback) -``` - -The sort parameter is used to specify which object to operate on, if more than -one document matches. It takes the same format as the cursor sort (see -Connection.find above). - -See the -[MongoDB docs for findAndModify](http://www.mongodb.org/display/DOCS/findAndModify+Command) -for more details. - -Useful options: - -* `remove:true` set to a true to remove the object before returning -* `new:true` set to true if you want to return the modified object rather than the original. Ignored for remove. -* `upsert:true` Atomically inserts the document if no documents matched. - -Example for `findAndModify`: - -```javascript - var MongoClient = require('mongodb').MongoClient - , format = require('util').format; - - MongoClient.connect('mongodb://127.0.0.1:27017/test', function(err, db) { - if(err) throw err; - db.collection('test').findAndModify({hello: 'world'}, [['_id','asc']], {$set: {hi: 'there'}}, {}, function(err, object) { - if (err) console.warn(err.message); - else console.dir(object); // undefined if no matching object exists. - }); - }); -``` - -Save ----- - -The `save` method is a shorthand for upsert if the document contains an -`_id`, or an insert if there is no `_id`. - -Sponsors -======== -Just as Felix Geisendörfer I'm also working on the driver for my own startup and this driver is a big project that also benefits other companies who are using MongoDB. - -If your company could benefit from a even better-engineered node.js mongodb driver I would appreciate any type of sponsorship you may be able to provide. All the sponsors will get a lifetime display in this readme, priority support and help on problems and votes on the roadmap decisions for the driver.

+/**
+ * @fileOverview GridFS is a tool for MongoDB to store files to the database.
+ * Because of the restrictions of the object size the database can hold, a
+ * facility to split a file into several chunks is needed. The {@link GridStore}
+ * class offers a simplified api to interact with files while managing the
+ * chunks of split files behind the scenes. More information about GridFS can be
+ * found here.
+ *
+ * @example
+ * var MongoClient = require('mongodb').MongoClient,
+ *   GridStore = require('mongodb').GridStore,
+ *   ObjectID = require('mongodb').ObjectID,
+ *   test = require('assert');
+ *
+ * // Connection url
+ * var url = 'mongodb://localhost:27017/test';
+ * // Connect using MongoClient
+ * MongoClient.connect(url, function(err, db) {
+ *   var gridStore = new GridStore(db, null, "w");
+ *   gridStore.open(function(err, gridStore) {
+ *     gridStore.write("hello world!", function(err, gridStore) {
+ *       gridStore.close(function(err, result) {
+ *
+ *         // Let's read the file using object Id
+ *         GridStore.read(db, result._id, function(err, data) {
+ *           test.equal('hello world!', data);
+ *           db.close();
+ *           test.done();
+ *         });

- * Constructor for a cursor object that handles all the operations on query result
- * using find. This cursor object is unidirectional and cannot traverse backwards. Clients should not be creating a cursor directly,
- * but use find to acquire a cursor. (INTERNAL TYPE)
- *
- * Options
- *  - **skip** {Number} skip number of documents to skip.
- *  - **limit** {Number}, limit the number of results to return. -1 has a special meaning and is used by Db.eval. A value of 1 will also be treated as if it were -1.
- *  - **sort** {Array | Object}, set to sort the documents coming back from the query. Array of indexes, [['a', 1]] etc.
- *  - **hint**  {Object}, hint force the query to use a specific index.
- *  - **explain** {Boolean}, explain return the explaination of the query.
- *  - **snapshot** {Boolean}, snapshot Snapshot mode assures no duplicates are returned.
- *  - **timeout** {Boolean}, timeout allow the query to timeout.
- *  - **tailable** {Boolean}, tailable allow the cursor to be tailable.
- *  - **awaitdata** {Boolean}, awaitdata allow the cursor to wait for data, only applicable for tailable cursor.
- *  - **batchSize** {Number}, batchSize the number of the subset of results to request the database to return for every request. This should initially be greater than 1 otherwise the database will automatically close the cursor. The batch size can be set to 1 with cursorInstance.batchSize after performing the initial query to the database.
- *  - **raw** {Boolean}, raw return all query documents as raw buffers (default false).
- *  - **read** {Boolean}, read specify override of read from source (primary/secondary).
- *  - **returnKey** {Boolean}, returnKey only return the index key.
- *  - **maxScan** {Number}, maxScan limit the number of items to scan.
- *  - **min** {Number}, min set index bounds.
- *  - **max** {Number}, max set index bounds.
- *  - **showDiskLoc** {Boolean}, showDiskLoc show disk location of results.
- *  - **comment** {String}, comment you can put a $comment field on a query to make looking in the profiler logs simpler.
- *  - **numberOfRetries** {Number}, numberOfRetries if using awaidata specifies the number of times to retry on timeout.
- *  - **dbName** {String}, dbName override the default dbName.
- *  - **tailableRetryInterval** {Number}, tailableRetryInterval specify the miliseconds between getMores on tailable cursor.
- *  - **exhaust** {Boolean}, exhaust have the server send all the documents at once as getMore packets.
- *  - **partial** {Boolean}, partial have the sharded system return a partial result from mongos.
- *
- * @class Represents a Cursor.
- * @param {Db} db the database object to work with.
- * @param {Collection} collection the collection to query.
- * @param {Object} selector the query selector.
- * @param {Object} fields an object containing what fields to include or exclude from objects returned.
- * @param {Object} [options] additional options for the collection.

- * chunks of split files behind the scenes. More information about GridFS can be

-Javascript + C++ BSON parser
-============================
-
-This BSON parser is primarily meant for usage with the `mongodb` node.js driver. However thanks to such wonderful tools at `onejs` we are able to package up a BSON parser that will work in the browser aswell. The current build is located in the `browser_build/bson.js` file.
-
-A simple example on how to use it
-
-    
-      
-    
-    
-    
-    
-
-  It's got two simple methods to use in your application.
-
-  * BSON.serialize(object, checkKeys, asBuffer, serializeFunctions)
-     * @param {Object} object the Javascript object to serialize.
-     * @param {Boolean} checkKeys the serializer will check if keys are valid.
-     * @param {Boolean} asBuffer return the serialized object as a Buffer object **(ignore)**.
-     * @param {Boolean} serializeFunctions serialize the javascript functions **(default:false)**
-     * @return {TypedArray/Array} returns a TypedArray or Array depending on what your browser supports
- 
-  * BSON.deserialize(buffer, options, isArray)
-     * Options
-       * **evalFunctions** {Boolean, default:false}, evaluate functions in the BSON document scoped to the object deserialized.
-       * **cacheFunctions** {Boolean, default:false}, cache evaluated functions for reuse.
-       * **cacheFunctionsCrc32** {Boolean, default:false}, use a crc32 code for caching, otherwise use the string of the function.
-     * @param {TypedArray/Array} a TypedArray/Array containing the BSON data
-     * @param {Object} [options] additional options used for the deserialization.
-     * @param {Boolean} [isArray] ignore used for recursive parsing.
-     * @return {Object} returns the deserialized Javascript Object.

+## Downloads
+
+* [es6-promise](https://raw.githubusercontent.com/jakearchibald/es6-promise/master/dist/es6-promise.js)
+* [es6-promise-min](https://raw.githubusercontent.com/jakearchibald/es6-promise/master/dist/es6-promise.min.js)
+
+## Node.js
+
+To install:
+
+```sh
+npm install es6-promise
+```
+
+To use:
+
+```js
+var Promise = require('es6-promise').Promise;
+```
+
+## Usage in IE<9
+
+`catch` is a reserved word in IE<9, meaning `promise.catch(func)` throws a syntax error. To work around this, you can use a string to access the property as shown in the following example.
+
+However, please remember that such technique is already provided by most common minifiers, making the resulting code safe for old browsers and production:
+
+```js
+promise['catch'](function(err) {
+  // ...
+});
+```
+
+Or use `.then` instead:
+
+```js
+promise.then(undefined, function(err) {
+  // ...
+});
+```
+
+## Auto-polyfill
+
+To polyfill the global environment (either in Node or in the browser via CommonJS) use the following code snippet:
+
+```js
+require('es6-promise').polyfill();
+```
+
+Notice that we don't assign the result of `polyfill()` to any variable. The `polyfill()` method will patch the global environment (in this case to the `Promise` name) when called.
+
+## Building & Testing
+
+* `npm run build` to build
+* `npm test` to run tests
+* `npm start` to run a build watcher, and webserver to test 
+* `npm run test:server` for a testem test runner and watching builder

+      Promise objects represent the eventual result of an asynchronous operation. The
+      primary way of interacting with a promise is through its `then` method, which
+      registers callbacks to receive either a promise's eventual value or the reason
+      why the promise cannot be fulfilled.
+
+      Terminology
+      -----------
+
+      - `promise` is an object or function with a `then` method whose behavior conforms to this specification.
+      - `thenable` is an object or function that defines a `then` method.
+      - `value` is any legal JavaScript value (including undefined, a thenable, or a promise).
+      - `exception` is a value that is thrown using the throw statement.
+      - `reason` is a value that indicates why a promise was rejected.
+      - `settled` the final resting state of a promise, fulfilled or rejected.
+
+      A promise can be in one of three states: pending, fulfilled, or rejected.
+
+      Promises that are fulfilled have a fulfillment value and are in the fulfilled
+      state.  Promises that are rejected have a rejection reason and are in the
+      rejected state.  A fulfillment value is never a thenable.
+
+      Promises can also be said to *resolve* a value.  If this value is also a
+      promise, then the original promise's settled state will match the value's
+      settled state.  So a promise that *resolves* a promise that rejects will
+      itself reject, and a promise that *resolves* a promise that fulfills will
+      itself fulfill.
+
+
+      Basic Usage:
+      ------------
+
+      ```js
+      var promise = new Promise(function(resolve, reject) {
+        // on success
+        resolve(value);
+
+        // on failure
+        reject(reason);
+      });
+
+      promise.then(function(value) {
+        // on fulfillment
+      }, function(reason) {
+        // on rejection
+      });
+      ```
+
+      Advanced Usage:
+      ---------------
+
+      Promises shine when abstracting away asynchronous interactions such as
+      `XMLHttpRequest`s.
+
+      ```js
+      function getJSON(url) {
+        return new Promise(function(resolve, reject){
+          var xhr = new XMLHttpRequest();
+
+          xhr.open('GET', url);
+          xhr.onreadystatechange = handler;
+          xhr.responseType = 'json';
+          xhr.setRequestHeader('Accept', 'application/json');
+          xhr.send();
+
+          function handler() {
+            if (this.readyState === this.DONE) {
+              if (this.status === 200) {
+                resolve(this.response);
+              } else {
+                reject(new Error('getJSON: `' + url + '` failed with status: [' + this.status + ']'));
+              }
+            }
+          };
+        });
+      }
+
+      getJSON('/posts.json').then(function(json) {
+        // on fulfillment
+      }, function(reason) {
+        // on rejection
+      });
+      ```
+
+      Unlike callbacks, promises are great composable primitives.
+
+      ```js
+      Promise.all([
+        getJSON('/posts'),
+        getJSON('/comments')
+      ]).then(function(values){
+        values[0] // => postsJSON
+        values[1] // => commentsJSON
+
+        return values;
+      });
+      ```

+    /**
+      The primary way of interacting with a promise is through its `then` method,
+      which registers callbacks to receive either a promise's eventual value or the
+      reason why the promise cannot be fulfilled.
+

+      findUser().then(function(user){
+        // user is available
+      }, function(reason){
+        // user is unavailable, and you are given the reason why
+      });
+      ```
+
+      Chaining
+      --------
+
+      The return value of `then` is itself a promise.  This second, 'downstream'
+      promise is resolved with the return value of the first promise's fulfillment
+      or rejection handler, or rejected if the handler throws an exception.
+
+      ```js
+      findUser().then(function (user) {
+        return user.name;
+      }, function (reason) {
+        return 'default name';
+      }).then(function (userName) {
+        // If `findUser` fulfilled, `userName` will be the user's name, otherwise it
+        // will be `'default name'`
+      });
+
+      findUser().then(function (user) {
+        throw new Error('Found user, but still unhappy');
+      }, function (reason) {
+        throw new Error('`findUser` rejected and we're unhappy');
+      }).then(function (value) {
+        // never reached
+      }, function (reason) {
+        // if `findUser` fulfilled, `reason` will be 'Found user, but still unhappy'.
+        // If `findUser` rejected, `reason` will be '`findUser` rejected and we're unhappy'.
+      });
+      ```
+      If the downstream promise does not specify a rejection handler, rejection reasons will be propagated further downstream.
+
+      ```js
+      findUser().then(function (user) {
+        throw new PedagogicalException('Upstream error');
+      }).then(function (value) {
+        // never reached
+      }).then(function (value) {
+        // never reached
+      }, function (reason) {
+        // The `PedgagocialException` is propagated all the way down to here
+      });
+      ```
+
+      Assimilation
+      ------------
+
+      Sometimes the value you want to propagate to a downstream promise can only be
+      retrieved asynchronously. This can be achieved by returning a promise in the
+      fulfillment or rejection handler. The downstream promise will then be pending
+      until the returned promise is settled. This is called *assimilation*.
+
+      ```js
+      findUser().then(function (user) {
+        return findCommentsByAuthor(user);
+      }).then(function (comments) {
+        // The user's comments are now available
+      });
+      ```
+
+      If the assimliated promise rejects, then the downstream promise will also reject.
+
+      ```js
+      findUser().then(function (user) {
+        return findCommentsByAuthor(user);
+      }).then(function (comments) {
+        // If `findCommentsByAuthor` fulfills, we'll have the value here
+      }, function (reason) {
+        // If `findCommentsByAuthor` rejects, we'll have the reason here
+      });
+      ```

+/**
+  The primary way of interacting with a promise is through its `then` method,
+  which registers callbacks to receive either a promise's eventual value or the
+  reason why the promise cannot be fulfilled.
+
+  ```js
+  findUser().then(function(user){
+    // user is available
+  }, function(reason){
+    // user is unavailable, and you are given the reason why
+  });
+  ```
+
+  Chaining
+  --------
+
+  The return value of `then` is itself a promise.  This second, 'downstream'
+  promise is resolved with the return value of the first promise's fulfillment
+  or rejection handler, or rejected if the handler throws an exception.
+
+  ```js
+  findUser().then(function (user) {
+    return user.name;
+  }, function (reason) {
+    return 'default name';
+  }).then(function (userName) {
+    // If `findUser` fulfilled, `userName` will be the user's name, otherwise it
+    // will be `'default name'`
+  });
+
+  findUser().then(function (user) {
+    throw new Error('Found user, but still unhappy');
+  }, function (reason) {
+    throw new Error('`findUser` rejected and we're unhappy');
+  }).then(function (value) {
+    // never reached
+  }, function (reason) {
+    // if `findUser` fulfilled, `reason` will be 'Found user, but still unhappy'.
+    // If `findUser` rejected, `reason` will be '`findUser` rejected and we're unhappy'.
+  });
+  ```
+  If the downstream promise does not specify a rejection handler, rejection reasons will be propagated further downstream.
+
+  ```js
+  findUser().then(function (user) {
+    throw new PedagogicalException('Upstream error');
+  }).then(function (value) {
+    // never reached
+  }).then(function (value) {
+    // never reached
+  }, function (reason) {
+    // The `PedgagocialException` is propagated all the way down to here
+  });
+  ```
+
+  Assimilation
+  ------------
+
+  Sometimes the value you want to propagate to a downstream promise can only be
+  retrieved asynchronously. This can be achieved by returning a promise in the
+  fulfillment or rejection handler. The downstream promise will then be pending
+  until the returned promise is settled. This is called *assimilation*.
+
+  ```js
+  findUser().then(function (user) {
+    return findCommentsByAuthor(user);
+  }).then(function (comments) {
+    // The user's comments are now available
+  });
+  ```
+
+  If the assimliated promise rejects, then the downstream promise will also reject.
+
+  ```js
+  findUser().then(function (user) {
+    return findCommentsByAuthor(user);
+  }).then(function (comments) {
+    // If `findCommentsByAuthor` fulfills, we'll have the value here
+  }, function (reason) {
+    // If `findCommentsByAuthor` rejects, we'll have the reason here
+  });
+  ```
+
+  Simple Example
+  --------------
+
+  Synchronous Example
+
+  ```javascript
+  var result;
+
+  try {
+    result = findResult();
+    // success
+  } catch(reason) {
+    // failure
+  }
+  ```
+
+  Errback Example
+
+  ```js
+  findResult(function(result, err){
+    if (err) {
+      // failure
+    } else {
+      // success
+    }

+1.3.18 2016-04-27
+-----------------
+- Hardened cursor connection handling for getMore and killCursor to ensure mid operation connection kill does not throw null exception.
+- Fixes for Node 6.0 support.
+
+1.3.17 2016-04-26
+-----------------
+- Added improved handling of reconnect when topology is a single server.
+- Added better handling of $query queries passed down for 3.2 or higher.
+- Introduced getServerFrom method to topologies to let cursor grab a new pool for getMore and killCursors commands and not use connection pipelining.
+- NODE-693 Move authentication to be after ismaster call to avoid authenticating against arbiters.
+
+1.3.16 2016-04-07
+-----------------
+- Only call unref on destroy if it exists to ensure proper working destroy method on early node v0.10.x versions.
+
+1.3.15 2016-04-06
+-----------------
+- NODE-687 Fixed issue where a server object failed to be destroyed if the replicaset state did not update successfully. This could leave active connections accumulating over time.
+- Fixed some situations where all connections are flushed due to a single connection in the connection pool closing.
+
+1.3.14 2016-04-01
+-----------------
+- Ensure server inquireServerState exits immediately on server.destroy call.
+- Refactored readPreference handling in 2.4, 2.6 and 3.2 wire protocol handling.
+
+1.3.13 2016-03-30
+-----------------
+- Handle missing cursor on getMore when going through a mongos proxy by pinning to socket connection and not server.
+
+1.3.12 2016-03-29
+-----------------
+- Mongos pickProxies fall back to closest mongos if no proxies meet latency window specified.
+
+1.3.11 2016-03-29
+-----------------
+- isConnected method for mongos uses same selection code as getServer.
+- Exceptions in cursor getServer trapped and correctly delegated to high level handler.
+
+1.3.10 2016-03-22
+-----------------
+- SDAM Monitoring emits diff for Replicasets to simplify detecting the state changes.
+- SDAM Monitoring correctly emits Mongos as serverDescriptionEvent.
+
+1.3.9 2016-03-20
+----------------
+- Removed monitoring exclusive connection, should resolve timeouts and reconnects on idle replicasets where haInteval > socketTimeout.
+
+1.3.8 2016-03-18
+----------------
+- Implements the SDAM monitoring specification.
+- Fix issue where cursor would error out and not be buffered when primary is not connected.
+
+1.3.7 2016-03-16
+----------------
+- Fixed issue with replicasetInquirer where it could stop performing monitoring if there was no servers available.
+
+1.3.6 2016-03-15
+----------------
+- Fixed raise condition where multiple replicasetInquirer operations could be started in parallel creating redundant connections.
+
+1.3.5 2016-03-14
+----------------
+- Handle rogue SSL exceptions (Issue #85, https://github.com/durran).
+
+1.3.4 2016-03-14
+----------------
+- Added unref options on server, replicaset and mongos (Issue #81, https://github.com/allevo)
+- cursorNotFound flag always false (Issue #83, https://github.com/xgfd)
+- refactor of events emission of fullsetup and all events (Issue #84, https://github.com/xizhibei)
+
+1.3.3 2016-03-08
+----------------
+- Added support for promoteLongs option for command function.
+- Return connection if no callback available
+- Emit connect event when server reconnects after initial connection failed (Issue #76, https://github.com/vkarpov15)
+- Introduced optional monitoringSocketTimeout option to allow better control of SDAM monitoring timeouts.
+- Made monitoringSocketTimeout default to 30000 if no connectionTimeout value specified or if set to 0.
+- Fixed issue where tailable cursor would not retry even though cursor was still alive.
+- Disabled exhaust flag support to avoid issues where users could easily write code that would cause memory to run out.
+- Handle the case where the first command result document returns an empty list of documents but a live cursor.
+- Allow passing down off CANONICALIZE_HOST_NAME and SERVICE_REALM options for kerberos.
+
+1.3.2 2016-02-09
+----------------
+- Harden MessageHandler in server.js to avoid issues where we cannot find a callback for an operation.
+- Ensure RequestId can never be larger than Max Number integer size.
+
+1.3.1 2016-02-05
+----------------
+- Removed annoying missing Kerberos error (NODE-654).
+
+1.3.0 2016-02-03
+----------------
+- Added raw support for the command function on topologies.
+- Fixed issue where raw results that fell on batchSize boundaries failed (Issue #72)
+- Copy over all the properties to the callback returned from bindToDomain, (Issue #72)
+- Added connection hash id to be able to reference connection host/name without leaking it outside of driver.
+- NODE-638, Cannot authenticate database user with utf-8 password.
+- Refactored pool to be worker queue based, minimizing the impact a slow query have on throughput as long as # slow queries < # connections in the pool.
+- Pool now grows and shrinks correctly depending on demand not causing a full pool reconnect.
+- Improvements in monitoring of a Replicaset where in certain situations the inquiry process could get exited.
+- Switched to using Array.push instead of concat for use cases of a lot of documents.
+- Fixed issue where re-authentication could loose the credentials if whole Replicaset disconnected at once.
+- Added peer optional dependencies support using require_optional module.
+
+1.2.32 2016-01-12
+-----------------
+- Bumped bson to V0.4.21 to allow using minor optimizations.
+
+1.2.31 2016-01-04
+-----------------
+- Allow connection to secondary if primaryPreferred or secondaryPreferred (Issue #70, https://github.com/leichter)
+
+1.2.30 2015-12-23
+-----------------
+- Pool allocates size + 1 connections when using replicasets, reserving additional pool connection for monitoring exclusively.
+- Fixes bug when all replicaset members are down, that would cause it to fail to reconnect using the originally provided seedlist.
+
+1.2.29 2015-12-17
+-----------------
+- Correctly emit close event when calling destroy on server topology.
+
+1.2.28 2015-12-13
+-----------------
+- Backed out Prevent Maximum call stack exceeded by calling all callbacks on nextTick, (Issue #64, https://github.com/iamruinous) as it breaks node 0.10.x support.
+
+1.2.27 2015-12-13
+-----------------
+- Added [options.checkServerIdentity=true] {boolean|function}. Ensure we check server identify during SSL, set to false to disable checking. Only works for Node 0.12.x or higher. You can pass in a boolean or your own checkServerIdentity override function, (Issue #29).
+- Prevent Maximum call stack exceeded by calling all callbacks on nextTick, (Issue #64, https://github.com/iamruinous).
+- State is not defined in mongos, (Issue #63, https://github.com/flyingfisher).
+- Fixed corner case issue on exhaust cursors on pre 3.0.x MongoDB.
+
+1.2.26 2015-11-23
+-----------------
+- Converted test suite to use mongodb-topology-manager.
+- Upgraded bson library to V0.4.20.
+- Minor fixes for 3.2 readPreferences.
+
+1.2.25 2015-11-23

+
+1.2.24 2015-11-20
+-----------------
+- Fix Automattic/mongoose#3481; flush callbacks on error, (Issue #57, https://github.com/vkarpov15).
+- $explain query for wire protocol 2.6 and 2.4 does not set number of returned documents to -1 but to 0.
+
+1.2.23 2015-11-16
+-----------------
+- ismaster runs against admin.$cmd instead of system.$cmd.
+
+1.2.22 2015-11-16
+-----------------
+- Fixes to handle getMore command errors for MongoDB 3.2
+- Allows the process to properly close upon a Db.close() call on the replica set by shutting down the haTimer and closing arbiter connections.

+-----------------
+- Hardened the checking for replicaset equality checks.
+- OpReplay flag correctly set on Wire protocol query.
+- Mongos load balancing added, introduced localThresholdMS to control the feature.

+# resolve-from [![Build Status](https://travis-ci.org/sindresorhus/resolve-from.svg?branch=master)](https://travis-ci.org/sindresorhus/resolve-from)
+
+> Resolve the path of a module like [`require.resolve()`](http://nodejs.org/api/globals.html#globals_require_resolve) but from a given path
+
+Unlike `require.resolve()` it returns `null` instead of throwing when the module can't be found.
+
+
+## Install
+
+```
+$ npm install --save resolve-from
+```
+
+
+## Usage
+
+```js
+const resolveFrom = require('resolve-from');
+
+// there's a file at `./foo/bar.js`
+
+resolveFrom('foo', './bar');
+//=> '/Users/sindresorhus/dev/test/foo/bar.js'
+```
+
+
+## API
+
+### resolveFrom(fromDir, moduleId)
+
+#### fromDir
+
+Type: `string`
+
+Directory to resolve from.
+
+#### moduleId
+
+Type: `string`
+
+What you would use in `require()`.
+
+
+## Tip
+
+Create a partial using a bound function if you want to require from the same `fromDir` multiple times:
+
+```js
+const resolveFromFoo = resolveFrom.bind(null, 'foo');
+
+resolveFromFoo('./bar');
+resolveFromFoo('./baz');
+```

+semver(1) -- The semantic versioner for npm
+===========================================
+
+## Usage
+
+    $ npm install semver
+    $ node
+    var semver = require('semver')
+
+    semver.valid('1.2.3') // '1.2.3'
+    semver.valid('a.b.c') // null
+    semver.clean('  =v1.2.3   ') // '1.2.3'
+    semver.satisfies('1.2.3', '1.x || >=2.5.0 || 5.0.0 - 7.2.3') // true
+    semver.gt('1.2.3', '9.8.7') // false
+    semver.lt('1.2.3', '9.8.7') // true
+
+As a command-line utility:
+
+    $ semver -h
+
+    SemVer 5.1.0
+
+    A JavaScript implementation of the http://semver.org/ specification
+    Copyright Isaac Z. Schlueter
+
+    Usage: semver [options]  [ [...]]
+    Prints valid versions sorted by SemVer precedence
+
+    Options:
+    -r --range 
+            Print versions that match the specified range.
+
+    -i --increment []
+            Increment a version by the specified level.  Level can
+            be one of: major, minor, patch, premajor, preminor,
+            prepatch, or prerelease.  Default level is 'patch'.
+            Only one version may be specified.
+
+    --preid 
+            Identifier to be used to prefix premajor, preminor,
+            prepatch or prerelease version increments.
+
+    -l --loose
+            Interpret versions and ranges loosely
+
+    Program exits successfully if any valid version satisfies
+    all supplied ranges, and prints all satisfying versions.
+
+    If no satisfying versions are found, then exits failure.
+
+    Versions are printed in ascending order, so supplying
+    multiple versions to the utility will just sort them.
+
+## Versions
+
+A "version" is described by the `v2.0.0` specification found at
+.
+
+A leading `"="` or `"v"` character is stripped off and ignored.
+
+## Ranges
+
+A `version range` is a set of `comparators` which specify versions
+that satisfy the range.
+
+A `comparator` is composed of an `operator` and a `version`.  The set
+of primitive `operators` is:
+
+* `<` Less than
+* `<=` Less than or equal to
+* `>` Greater than
+* `>=` Greater than or equal to
+* `=` Equal.  If no operator is specified, then equality is assumed,
+  so this operator is optional, but MAY be included.
+
+For example, the comparator `>=1.2.7` would match the versions
+`1.2.7`, `1.2.8`, `2.5.3`, and `1.3.9`, but not the versions `1.2.6`
+or `1.1.0`.
+
+Comparators can be joined by whitespace to form a `comparator set`,
+which is satisfied by the **intersection** of all of the comparators
+it includes.
+
+A range is composed of one or more comparator sets, joined by `||`.  A
+version matches a range if and only if every comparator in at least
+one of the `||`-separated comparator sets is satisfied by the version.
+
+For example, the range `>=1.2.7 <1.3.0` would match the versions
+`1.2.7`, `1.2.8`, and `1.2.99`, but not the versions `1.2.6`, `1.3.0`,
+or `1.1.0`.
+
+The range `1.2.7 || >=1.2.9 <2.0.0` would match the versions `1.2.7`,
+`1.2.9`, and `1.4.6`, but not the versions `1.2.8` or `2.0.0`.
+
+### Prerelease Tags
+
+If a version has a prerelease tag (for example, `1.2.3-alpha.3`) then
+it will only be allowed to satisfy comparator sets if at least one
+comparator with the same `[major, minor, patch]` tuple also has a
+prerelease tag.
+
+For example, the range `>1.2.3-alpha.3` would be allowed to match the
+version `1.2.3-alpha.7`, but it would *not* be satisfied by
+`3.4.5-alpha.9`, even though `3.4.5-alpha.9` is technically "greater
+than" `1.2.3-alpha.3` according to the SemVer sort rules.  The version
+range only accepts prerelease tags on the `1.2.3` version.  The
+version `3.4.5` *would* satisfy the range, because it does not have a
+prerelease flag, and `3.4.5` is greater than `1.2.3-alpha.7`.
+
+The purpose for this behavior is twofold.  First, prerelease versions
+frequently are updated very quickly, and contain many breaking changes
+that are (by the author's design) not yet fit for public consumption.
+Therefore, by default, they are excluded from range matching
+semantics.
+
+Second, a user who has opted into using a prerelease version has
+clearly indicated the intent to use *that specific* set of
+alpha/beta/rc versions.  By including a prerelease tag in the range,
+the user is indicating that they are aware of the risk.  However, it
+is still not appropriate to assume that they have opted into taking a
+similar risk on the *next* set of prerelease versions.
+
+#### Prerelease Identifiers
+
+The method `.inc` takes an additional `identifier` string argument that
+will append the value of the string as a prerelease identifier:
+
+```javascript
+> semver.inc('1.2.3', 'prerelease', 'beta')
+'1.2.4-beta.0'
+```
+
+command-line example:
+
+```shell
+$ semver 1.2.3 -i prerelease --preid beta
+1.2.4-beta.0
+```
+
+Which then can be used to increment further:
+
+```shell
+$ semver 1.2.4-beta.0 -i prerelease
+1.2.4-beta.1
+```
+
+### Advanced Range Syntax
+
+Advanced range syntax desugars to primitive comparators in
+deterministic ways.
+
+Advanced ranges may be combined in the same way as primitive
+comparators using white space or `||`.
+
+#### Hyphen Ranges `X.Y.Z - A.B.C`
+
+Specifies an inclusive set.
+
+* `1.2.3 - 2.3.4` := `>=1.2.3 <=2.3.4`
+
+If a partial version is provided as the first version in the inclusive
+range, then the missing pieces are replaced with zeroes.
+
+* `1.2 - 2.3.4` := `>=1.2.0 <=2.3.4`
+
+If a partial version is provided as the second version in the
+inclusive range, then all versions that start with the supplied parts
+of the tuple are accepted, but nothing that would be greater than the
+provided tuple parts.
+
+* `1.2.3 - 2.3` := `>=1.2.3 <2.4.0`
+* `1.2.3 - 2` := `>=1.2.3 <3.0.0`
+
+#### X-Ranges `1.2.x` `1.X` `1.2.*` `*`
+
+Any of `X`, `x`, or `*` may be used to "stand in" for one of the
+numeric values in the `[major, minor, patch]` tuple.
+
+* `*` := `>=0.0.0` (Any version satisfies)
+* `1.x` := `>=1.0.0 <2.0.0` (Matching major version)
+* `1.2.x` := `>=1.2.0 <1.3.0` (Matching major and minor versions)
+
+A partial version range is treated as an X-Range, so the special
+character is in fact optional.
+
+* `""` (empty string) := `*` := `>=0.0.0`
+* `1` := `1.x.x` := `>=1.0.0 <2.0.0`
+* `1.2` := `1.2.x` := `>=1.2.0 <1.3.0`
+
+#### Tilde Ranges `~1.2.3` `~1.2` `~1`
+
+Allows patch-level changes if a minor version is specified on the
+comparator.  Allows minor-level changes if not.
+
+* `~1.2.3` := `>=1.2.3 <1.(2+1).0` := `>=1.2.3 <1.3.0`
+* `~1.2` := `>=1.2.0 <1.(2+1).0` := `>=1.2.0 <1.3.0` (Same as `1.2.x`)
+* `~1` := `>=1.0.0 <(1+1).0.0` := `>=1.0.0 <2.0.0` (Same as `1.x`)
+* `~0.2.3` := `>=0.2.3 <0.(2+1).0` := `>=0.2.3 <0.3.0`
+* `~0.2` := `>=0.2.0 <0.(2+1).0` := `>=0.2.0 <0.3.0` (Same as `0.2.x`)
+* `~0` := `>=0.0.0 <(0+1).0.0` := `>=0.0.0 <1.0.0` (Same as `0.x`)
+* `~1.2.3-beta.2` := `>=1.2.3-beta.2 <1.3.0` Note that prereleases in
+  the `1.2.3` version will be allowed, if they are greater than or
+  equal to `beta.2`.  So, `1.2.3-beta.4` would be allowed, but
+  `1.2.4-beta.2` would not, because it is a prerelease of a
+  different `[major, minor, patch]` tuple.
+
+#### Caret Ranges `^1.2.3` `^0.2.5` `^0.0.4`
+
+Allows changes that do not modify the left-most non-zero digit in the
+`[major, minor, patch]` tuple.  In other words, this allows patch and
+minor updates for versions `1.0.0` and above, patch updates for
+versions `0.X >=0.1.0`, and *no* updates for versions `0.0.X`.
+
+Many authors treat a `0.x` version as if the `x` were the major
+"breaking-change" indicator.
+
+Caret ranges are ideal when an author may make breaking changes
+between `0.2.4` and `0.3.0` releases, which is a common practice.
+However, it presumes that there will *not* be breaking changes between
+`0.2.4` and `0.2.5`.  It allows for changes that are presumed to be
+additive (but non-breaking), according to commonly observed practices.
+
+* `^1.2.3` := `>=1.2.3 <2.0.0`
+* `^0.2.3` := `>=0.2.3 <0.3.0`
+* `^0.0.3` := `>=0.0.3 <0.0.4`
+* `^1.2.3-beta.2` := `>=1.2.3-beta.2 <2.0.0` Note that prereleases in
+  the `1.2.3` version will be allowed, if they are greater than or
+  equal to `beta.2`.  So, `1.2.3-beta.4` would be allowed, but
+  `1.2.4-beta.2` would not, because it is a prerelease of a
+  different `[major, minor, patch]` tuple.
+* `^0.0.3-beta` := `>=0.0.3-beta <0.0.4`  Note that prereleases in the
+  `0.0.3` version *only* will be allowed, if they are greater than or
+  equal to `beta`.  So, `0.0.3-pr.2` would be allowed.
+
+When parsing caret ranges, a missing `patch` value desugars to the
+number `0`, but will allow flexibility within that value, even if the
+major and minor versions are both `0`.
+
+* `^1.2.x` := `>=1.2.0 <2.0.0`
+* `^0.0.x` := `>=0.0.0 <0.1.0`
+* `^0.0` := `>=0.0.0 <0.1.0`
+
+A missing `minor` and `patch` values will desugar to zero, but also
+allow flexibility within those values, even if the major version is
+zero.
+
+* `^1.x` := `>=1.0.0 <2.0.0`
+* `^0.x` := `>=0.0.0 <1.0.0`
+
+### Range Grammar
+
+Putting all this together, here is a Backus-Naur grammar for ranges,
+for the benefit of parser authors:
+
+```bnf
+range-set  ::= range ( logical-or range ) *
+logical-or ::= ( ' ' ) * '||' ( ' ' ) *
+range      ::= hyphen | simple ( ' ' simple ) * | ''
+hyphen     ::= partial ' - ' partial
+simple     ::= primitive | partial | tilde | caret
+primitive  ::= ( '<' | '>' | '>=' | '<=' | '=' | ) partial
+partial    ::= xr ( '.' xr ( '.' xr qualifier ? )? )?
+xr         ::= 'x' | 'X' | '*' | nr
+nr         ::= '0' | ['1'-'9'] ( ['0'-'9'] ) *
+tilde      ::= '~' partial
+caret      ::= '^' partial
+qualifier  ::= ( '-' pre )? ( '+' build )?
+pre        ::= parts
+build      ::= parts
+parts      ::= part ( '.' part ) *
+part       ::= nr | [-0-9A-Za-z]+
+```
+
+## Functions
+
+All methods and classes take a final `loose` boolean argument that, if
+true, will be more forgiving about not-quite-valid semver strings.
+The resulting output will always be 100% strict, of course.
+
+Strict-mode Comparators and Ranges will be strict about the SemVer
+strings that they parse.
+
+* `valid(v)`: Return the parsed version, or null if it's not valid.
+* `inc(v, release)`: Return the version incremented by the release
+  type (`major`,   `premajor`, `minor`, `preminor`, `patch`,
+  `prepatch`, or `prerelease`), or null if it's not valid
+  * `premajor` in one call will bump the version up to the next major
+    version and down to a prerelease of that major version.
+    `preminor`, and `prepatch` work the same way.
+  * If called from a non-prerelease version, the `prerelease` will work the
+    same as `prepatch`. It increments the patch version, then makes a
+    prerelease. If the input version is already a prerelease it simply
+    increments it.
+* `prerelease(v)`: Returns an array of prerelease components, or null
+  if none exist. Example: `prerelease('1.2.3-alpha.1') -> ['alpha', 1]`
+* `major(v)`: Return the major version number.
+* `minor(v)`: Return the minor version number.
+* `patch(v)`: Return the patch version number.
+
+### Comparison
+
+* `gt(v1, v2)`: `v1 > v2`
+* `gte(v1, v2)`: `v1 >= v2`
+* `lt(v1, v2)`: `v1 < v2`
+* `lte(v1, v2)`: `v1 <= v2`
+* `eq(v1, v2)`: `v1 == v2` This is true if they're logically equivalent,
+  even if they're not the exact same string.  You already know how to
+  compare strings.
+* `neq(v1, v2)`: `v1 != v2` The opposite of `eq`.
+* `cmp(v1, comparator, v2)`: Pass in a comparison string, and it'll call
+  the corresponding function above.  `"==="` and `"!=="` do simple
+  string comparison, but are included for completeness.  Throws if an
+  invalid comparison string is provided.
+* `compare(v1, v2)`: Return `0` if `v1 == v2`, or `1` if `v1` is greater, or `-1` if
+  `v2` is greater.  Sorts in ascending order if passed to `Array.sort()`.
+* `rcompare(v1, v2)`: The reverse of compare.  Sorts an array of versions
+  in descending order when passed to `Array.sort()`.
+* `diff(v1, v2)`: Returns difference between two versions by the release type
+  (`major`, `premajor`, `minor`, `preminor`, `patch`, `prepatch`, or `prerelease`),
+  or null if the versions are the same.
+
+
+### Ranges
+
+* `validRange(range)`: Return the valid range or null if it's not valid
+* `satisfies(version, range)`: Return true if the version satisfies the
+  range.
+* `maxSatisfying(versions, range)`: Return the highest version in the list
+  that satisfies the range, or `null` if none of them do.
+* `minSatisfying(versions, range)`: Return the lowest version in the list
+  that satisfies the range, or `null` if none of them do.
+* `gtr(version, range)`: Return `true` if version is greater than all the
+  versions possible in the range.
+* `ltr(version, range)`: Return `true` if version is less than all the
+  versions possible in the range.
+* `outside(version, range, hilo)`: Return true if the version is outside
+  the bounds of the range in either the high or low direction.  The
+  `hilo` argument must be either the string `'>'` or `'<'`.  (This is
+  the function called by `gtr` and `ltr`.)
+
+Note that, since ranges may be non-contiguous, a version might not be
+greater than a range, less than a range, *or* satisfy a range!  For
+example, the range `1.2 <1.2.9 || >2.0.0` would have a hole from `1.2.9`
+until `2.0.0`, so the version `1.2.10` would not be greater than the
+range (because `2.0.1` satisfies, which is higher), nor less than the
+range (since `1.2.8` satisfies, which is lower), and it also does not
+satisfy the range.
+
+If you want to know if a version satisfies or does not satisfy a
+range, use the `satisfies(version, range)` function.

+***Node-core streams for userland***
+
+[![NPM](https://nodei.co/npm/readable-stream.png?downloads=true)](https://nodei.co/npm/readable-stream/)
+[![NPM](https://nodei.co/npm-dl/readable-stream.png)](https://nodei.co/npm/readable-stream/)
+
+This package is a mirror of the Streams2 and Streams3 implementations in Node-core.
+
+If you want to guarantee a stable streams base, regardless of what version of Node you, or the users of your libraries are using, use **readable-stream** *only* and avoid the *"stream"* module in Node-core.
+
+**readable-stream** comes in two major versions, v1.0.x and v1.1.x. The former tracks the Streams2 implementation in Node 0.10, including bug-fixes and minor improvements as they are added. The latter tracks Streams3 as it develops in Node 0.11; we will likely see a v1.2.x branch for Node 0.12.
+
+**readable-stream** uses proper patch-level versioning so if you pin to `"~1.0.0"` you’ll get the latest Node 0.10 Streams2 implementation, including any fixes and minor non-breaking improvements. The patch-level versions of 1.0.x and 1.1.x should mirror the patch-level versions of Node-core releases. You should prefer the **1.0.x** releases for now and when you’re ready to start using Streams3, pin to `"~1.1.0"`

+
+// a transform stream is a readable/writable stream where you do
+// something with the data.  Sometimes it's called a "filter",
+// but that's not a great name for it, since that implies a thing where
+// some bits pass through, and others are simply ignored.  (That would
+// be a valid example of a transform, of course.)
+//
+// While the output is causally related to the input, it's not a
+// necessarily symmetric or synchronous transformation.  For example,
+// a zlib stream might take multiple plain-text writes(), and then
+// emit a single compressed chunk some time in the future.
+//
+// Here's how this works:
+//
+// The Transform stream has all the aspects of the readable and writable
+// stream classes.  When you write(chunk), that calls _write(chunk,cb)
+// internally, and returns false if there's a lot of pending writes
+// buffered up.  When you call read(), that calls _read(n) until
+// there's enough pending readable data buffered up.
+//
+// In a transform stream, the written data is placed in a buffer.  When
+// _read(n) is called, it transforms the queued up data, calling the
+// buffered _write cb's as it consumes chunks.  If consuming a single
+// written chunk would result in multiple output chunks, then the first
+// outputted bit calls the readcb, and subsequent chunks just go into
+// the read buffer, and will cause it to emit 'readable' if necessary.
+//
+// This way, back-pressure is actually determined by the reading side,
+// since _read has to be called to start processing a new chunk.  However,
+// a pathological inflate type of transform can cause excessive buffering
+// here.  For example, imagine a stream where every byte of input is
+// interpreted as an integer from 0-255, and then results in that many
+// bytes of output.  Writing the 4 bytes {ff,ff,ff,ff} would result in
+// 1kb of data being output.  In this case, you could write a very small
+// amount of input, and end up with a very large amount of output.  In
+// such a pathological inflating mechanism, there'd be no way to tell
+// the system to stop doing the transform.  A single 4MB write could
+// cause the system to run out of memory.
+//
+// However, even in such a pathological case, only a single written chunk
+// would be consumed, and then the rest would wait (un-transformed) until
+// the results of the previous transformed chunk were consumed.

+Browser-friendly inheritance fully compatible with standard node.js
+[inherits](http://nodejs.org/api/util.html#util_util_inherits_constructor_superconstructor).
+
+This package exports standard `inherits` from node.js `util` module in
+node environment, but also provides alternative browser-friendly
+implementation through [browser
+field](https://gist.github.com/shtylman/4339901). Alternative
+implementation is a literal copy of standard one located in standalone
+module to avoid requiring of `util`. It also has a shim for old
+browsers with no `Object.create` support.
+
+While keeping you sure you are using standard `inherits`
+implementation in node.js environment, it allows bundlers such as
+[browserify](https://github.com/substack/node-browserify) to not
+include full `util` package to your client code if all you need is
+just `inherits` function. It worth, because browser shim for `util`
+package is large and `inherits` is often the single function you need
+from it.
+
+It's recommended to use this package instead of
+`require('util').inherits` for any code that has chances to be used
+not only in node.js but in browser too.
+
+## usage
+
+```js
+var inherits = require('inherits');
+// then use exactly as the standard one
+```
+
+## note on version ~1.0
+
+Version ~1.0 had completely different motivation and is not compatible
+neither with 2.0 nor with standard node.js `inherits`.
+
+If you are using version ~1.0 and planning to switch to ~2.0, be
+careful:
+
+* new version uses `super_` instead of `super` for referencing
+  superclass
+* new version overwrites current prototype while old one preserves any
+  existing fields on it

+#mquery
+===========
+
+`mquery` is a fluent mongodb query builder designed to run in multiple environments. As of v0.1, `mquery` runs on `Node.js` only with support for the MongoDB shell and browser environments planned for upcoming releases.
+
+##Features
+
+  - fluent query builder api
+  - custom base query support
+  - MongoDB 2.4 geoJSON support
+  - method + option combinations validation
+  - node.js driver compatibility
+  - environment detection
+  - [debug](https://github.com/visionmedia/debug) support
+  - separated collection implementations for maximum flexibility
+
+[![Build Status](https://travis-ci.org/aheckmann/mquery.png)](https://travis-ci.org/aheckmann/mquery)
+
+##Use
+
+```js
+require('mongodb').connect(uri, function (err, db) {
+  if (err) return handleError(err);
+
+  // get a collection
+  var collection = db.collection('artists');
+
+  // pass it to the constructor
+  mquery(collection).find({..}, callback);
+
+  // or pass it to the collection method
+  mquery().find({..}).collection(collection).exec(callback)
+
+  // or better yet, create a custom query constructor that has it always set
+  var Artist = mquery(collection).toConstructor();
+  Artist().find(..).where(..).exec(callback)
+})
+```
+
+`mquery` requires a collection object to work with. In the example above we just pass the collection object created using the official [MongoDB driver](https://github.com/mongodb/node-mongodb-native).

+
+###find()
+
+Declares this query a _find_ query. Optionally pass a match clause and / or callback. If a callback is passed the query is executed.
+
+```js
+mquery().find()
+mquery().find(match)
+mquery().find(callback)
+mquery().find(match, function (err, docs) {
+  assert(Array.isArray(docs));
+})
+```
+
+###findOne()
+
+Declares this query a _findOne_ query. Optionally pass a match clause and / or callback. If a callback is passed the query is executed.
+
+```js
+mquery().findOne()
+mquery().findOne(match)
+mquery().findOne(callback)
+mquery().findOne(match, function (err, doc) {
+  if (doc) {
+    // the document may not be found
+    console.log(doc);
+  }
+})
+```
+
+###count()
+
+Declares this query a _count_ query. Optionally pass a match clause and / or callback. If a callback is passed the query is executed.
+
+```js
+mquery().count()
+mquery().count(match)
+mquery().count(callback)
+mquery().count(match, function (err, number){
+  console.log('we found %d matching documents', number);
+})
+```
+
+###remove()
+
+Declares this query a _remove_ query. Optionally pass a match clause and / or callback. If a callback is passed the query is executed.
+
+```js
+mquery().remove()
+mquery().remove(match)
+mquery().remove(callback)
+mquery().remove(match, function (err){})
+```
+
+###update()
+
+Declares this query an _update_ query. Optionally pass an update document, match clause, options or callback. If a callback is passed, the query is executed. To force execution without passing a callback, run `update(true)`.
+
+```js
+mquery().update()
+mquery().update(match, updateDocument)
+mquery().update(match, updateDocument, options)
+
+// the following all execute the command
+mquery().update(callback)
+mquery().update({$set: updateDocument, callback)
+mquery().update(match, updateDocument, callback)
+mquery().update(match, updateDocument, options, function (err, result){})
+mquery().update(true) // executes (unsafe write)
+```
+
+#####the update document
+
+All paths passed that are not `$atomic` operations will become `$set` ops. For example:
+
+```js
+mquery(collection).where({ _id: id }).update({ title: 'words' }, callback)
+```
+
+becomes
+
+```js
+collection.update({ _id: id }, { $set: { title: 'words' }}, callback)
+```
+
+This behavior can be overridden using the `overwrite` option (see below).
+
+#####options
+
+Options are passed to the `setOptions()` method.
+
+- overwrite
+
+Passing an empty object `{ }` as the update document will result in a no-op unless the `overwrite` option is passed. Without the `overwrite` option, the update operation will be ignored and the callback executed without sending the command to MongoDB to prevent accidently overwritting documents in the collection.
+
+```js
+var q = mquery(collection).where({ _id: id }).setOptions({ overwrite: true });
+q.update({ }, callback); // overwrite with an empty doc
+```
+
+The `overwrite` option isn't just for empty objects, it also provides a means to override the default `$set` conversion and send the update document as is.
+
+```js
+// create a base query
+var base = mquery({ _id: 108 }).collection(collection).toConstructor();
+
+base().findOne(function (err, doc) {
+  console.log(doc); // { _id: 108, name: 'cajon' })
+
+  base().setOptions({ overwrite: true }).update({ changed: true }, function (err) {
+    base.findOne(function (err, doc) {
+      console.log(doc); // { _id: 108, changed: true }) - the doc was overwritten
+    });
+  });
+})
+```
+
+- multi
+
+Updates only modify a single document by default. To update multiple documents, set the `multi` option to `true`.
+
+```js
+mquery()
+  .collection(coll)
+  .update({ name: /^match/ }, { $addToSet: { arr: 4 }}, { multi: true }, callback)
+
+// another way of doing it
+mquery({ name: /^match/ })
+  .collection(coll)
+  .setOptions({ multi: true })
+  .update({ $addToSet: { arr: 4 }}, callback)
+
+// update multiple documents with an empty doc
+var q = mquery(collection).where({ name: /^match/ });
+q.setOptions({ multi: true, overwrite: true })
+q.update({ });
+q.update(function (err, result) {
+  console.log(arguments);
+});
+```
+
+###findOneAndUpdate()
+
+Declares this query a _findAndModify_ with update query. Optionally pass a match clause, update document, options, or callback. If a callback is passed, the query is executed.
+
+When executed, the first matching document (if found) is modified according to the update document and passed back to the callback.
+
+#####options
+
+Options are passed to the `setOptions()` method.
+
+- `new`: boolean - true to return the modified document rather than the original. defaults to true
+- `upsert`: boolean - creates the object if it doesn't exist. defaults to false
+- `sort`: if multiple docs are found by the match condition, sets the sort order to choose which doc to update
+
+```js
+query.findOneAndUpdate()
+query.findOneAndUpdate(updateDocument)
+query.findOneAndUpdate(match, updateDocument)
+query.findOneAndUpdate(match, updateDocument, options)
+
+// the following all execute the command
+query.findOneAndUpdate(callback)
+query.findOneAndUpdate(updateDocument, callback)
+query.findOneAndUpdate(match, updateDocument, callback)
+query.findOneAndUpdate(match, updateDocument, options, function (err, doc) {
+  if (doc) {
+    // the document may not be found
+    console.log(doc);
+  }
+})
+ ```
+
+###findOneAndRemove()
+
+Declares this query a _findAndModify_ with remove query. Optionally pass a match clause, options, or callback. If a callback is passed, the query is executed.
+
+When executed, the first matching document (if found) is modified according to the update document, removed from the collection and passed to the callback.
+
+#####options
+
+Options are passed to the `setOptions()` method.
+
+- `sort`: if multiple docs are found by the condition, sets the sort order to choose which doc to modify and remove
+
+```js
+A.where().findOneAndRemove()
+A.where().findOneAndRemove(match)
+A.where().findOneAndRemove(match, options)
+
+// the following all execute the command
+A.where().findOneAndRemove(callback)
+A.where().findOneAndRemove(match, callback)
+A.where().findOneAndRemove(match, options, function (err, doc) {
+  if (doc) {
+    // the document may not be found
+    console.log(doc);
+  }
+})
+ ```
+
+###distinct()
+
+Declares this query a _distinct_ query. Optionally pass the distinct field, a match clause or callback. If a callback is passed the query is executed.
+
+```js
+mquery().distinct()
+mquery().distinct(match)
+mquery().distinct(match, field)
+mquery().distinct(field)
+
+// the following all execute the command
+mquery().distinct(callback)
+mquery().distinct(field, callback)
+mquery().distinct(match, callback)
+mquery().distinct(match, field, function (err, result) {
+  console.log(result);
+})
+```
+
+###exec()
+
+Executes the query.
+
+```js
+mquery().findOne().where('route').intersects(polygon).exec(function (err, docs){})
+```
+
+###stream()
+
+Executes the query and returns a stream.
+
+```js
+var stream = mquery().find().stream(options);
+stream.on('data', cb);
+stream.on('close', fn);
+```
+
+Note: this only works with `find()` operations.
+
+Note: returns the stream object directly from the node-mongodb-native driver. (currently streams1 type stream). Any options will be passed along to the [driver method](http://mongodb.github.io/node-mongodb-native/api-generated/cursor.html#stream).

+
+###near()
+
+Specifies arguments for a `$near` or `$nearSphere` condition.
+
+These operators return documents sorted by distance.
+
+####Example
+
+```js
+query.where('loc').near({ center: [10, 10] });

+
+// or
+
+mquery().select('name address -_id')
+```
+
+#####String syntax
+
+When passing a string, prefixing a path with `-` will flag that path as excluded. When a path does not have the `-` prefix, it is included.
+
+```js
+// include a and b, exclude c
+query.select('a b -c');
+
+// or you may use object notation, useful when
+// you have keys already prefixed with a "-"
+query.select({a: 1, b: 1, c: 0});

+query.selectedExclusively() // true
+
+var query = mquery();
+query.selected() // false
+query.select('name');
+query.selectedExclusively() // false

+
+```js
+mquery().where('someArray').size(6)
+```
+
+[MongoDB Documentation](http://docs.mongodb.org/manual/reference/operator/size/)
+
+###slice()
+
+Specifies a `$slice` projection for a `path`
+
+```js
+mquery().where('comments').slice(5)
+mquery().where('comments').slice(-5)
+mquery().where('comments').slice([-10, 5])
+```
+
+[MongoDB Documentation](http://docs.mongodb.org/manual/reference/projection/slice/)
+
+###within()
+
+Sets a `$geoWithin` or `$within` argument for geo-spatial queries.
+
+```js
+mquery().within().box()
+mquery().within().circle()
+mquery().within().geometry()
+
+mquery().where('loc').within({ center: [50,50], radius: 10, unique: true, spherical: true });
+mquery().where('loc').within({ box: [[40.73, -73.9], [40.7, -73.988]] });

+
+mquery().where('loc').within([], [], []) // polygon
+mquery().where('loc').within([], []) // box
+mquery().where('loc').within({ type: 'LineString', coordinates: [...] }); // geometry
+```
+
+As of mquery 2.0, `$geoWithin` is used by default. This impacts you if running MongoDB < 2.4. To alter this behavior, see [mquery.use$geoWithin](#mqueryusegeowithin).
+
+**Must** be used after `where()`.
+
+[MongoDB Documentation](http://docs.mongodb.org/manual/reference/operator/geoWithin/)
+
+###where()
+
+Specifies a `path` for use with chaining
+
+```js
+// instead of writing:
+mquery().find({age: {$gte: 21, $lte: 65}});
+
+// we can instead write:
+mquery().where('age').gte(21).lte(65);
+
+// passing query conditions is permitted too
+mquery().find().where({ name: 'vonderful' })
+
+// chaining
+mquery()
+.where('age').gte(21).lte(65)
+.where({ 'name': /^vonderful/i })
+.where('friends').slice(10)
+.exec(callback)
+```
+
+###$where()
+
+Specifies a `$where` condition.
+
+Use `$where` when you need to select documents using a JavaScript expression.
+
+```js
+query.$where('this.comments.length > 10 || this.name.length > 5').exec(callback)
+
+query.$where(function () {
+  return this.comments.length > 10 || this.name.length > 5;
+})
+```
+
+Only use `$where` when you have a condition that cannot be met using other MongoDB operators like `$lt`. Be sure to read about all of [its caveats](http://docs.mongodb.org/manual/reference/operator/where/) before using.
+
+-----------
+
+###batchSize()
+
+Specifies the batchSize option.
+
+```js

+```
+
+[MongoDB documentation](http://docs.mongodb.org/manual/reference/method/cursor.maxTimeMS/)

+```js
+query.skip(100).limit(20)
+```
+
+_Cannot be used with `distinct()`._
+
+[MongoDB documentation](http://docs.mongodb.org/manual/reference/method/cursor.skip/)
+
+###sort()
+
+Sets the query sort order.
+
+If an object is passed, key values allowed are `asc`, `desc`, `ascending`, `descending`, `1`, and `-1`.
+
+If a string is passed, it must be a space delimited list of path names. The sort order of each path is ascending unless the path name is prefixed with `-` which will be treated as descending.
+
+```js
+// these are equivalent
+query.sort({ field: 'asc', test: -1 });
+query.sort('field -test');
+```
+
+_Cannot be used with `distinct()`._

+[MongoDB documentation](http://docs.mongodb.org/manual/reference/method/cursor.sort/)
+
+###read()
+
+Sets the readPreference option for the query.
+
+```js
+mquery().read('primary')
+mquery().read('p')  // same as primary
+
+mquery().read('primaryPreferred')
+mquery().read('pp') // same as primaryPreferred
+
+mquery().read('secondary')
+mquery().read('s')  // same as secondary
+
+mquery().read('secondaryPreferred')
+mquery().read('sp') // same as secondaryPreferred
+
+mquery().read('nearest')
+mquery().read('n')  // same as nearest
+```
+
+#####Preferences:
+
+- `primary` - (default) Read from primary only. Operations will produce an error if primary is unavailable. Cannot be combined with tags.
+- `secondary` - Read from secondary if available, otherwise error.
+- `primaryPreferred` - Read from primary if available, otherwise a secondary.
+- `secondaryPreferred` - Read from a secondary if available, otherwise read from the primary.
+- `nearest` - All operations read from among the nearest candidates, but unlike other modes, this option will include both the primary and all secondaries in the random selection.
+
+Aliases
+
+- `p`   primary
+- `pp`  primaryPreferred
+- `s`   secondary
+- `sp`  secondaryPreferred
+- `n`   nearest
+
+#####Preference Tags:
+
+To keep the separation of concerns between `mquery` and your driver
+clean, `mquery#read()` no longer handles specifying a second `tags` argument as of version 0.5.
+If you need to specify tags, pass any non-string argument as the first argument.
+`mquery` will pass this argument untouched to your collections methods later.
+For example:
+
+```js
+// example of specifying tags using the Node.js driver
+var ReadPref = require('mongodb').ReadPreference;
+var preference = new ReadPref('secondary', [{ dc:'sf', s: 1 },{ dc:'ma', s: 2 }]);
+mquery(..).read(preference).exec();
+```
+
+Read more about how to use read preferences [here](http://docs.mongodb.org/manual/applications/replication/#read-preference) and [here](http://mongodb.github.com/node-mongodb-native/driver-articles/anintroductionto1_1and2_2.html#read-preferences).
+
+###slaveOk()
+
+Sets the slaveOk option. `true` allows reading from secondaries.
+
+**deprecated** use [read()](#read) preferences instead if on mongodb >= 2.2
+
+```js
+query.slaveOk() // true
+query.slaveOk(true)
+query.slaveOk(false)
+```
+
+[MongoDB documentation](http://docs.mongodb.org/manual/reference/method/rs.slaveOk/)
+
+###snapshot()
+
+Specifies this query as a snapshot query.
+
+```js
+mquery().snapshot() // true
+mquery().snapshot(true)
+mquery().snapshot(false)
+```
+
+_Cannot be used with `distinct()`._
+
+[MongoDB documentation](http://docs.mongodb.org/manual/reference/operator/snapshot/)
+
+###tailable()
+
+Sets tailable option.
+
+```js
+mquery().tailable() <== true
+mquery().tailable(true)
+mquery().tailable(false)
+```
+
+_Cannot be used with `distinct()`._
+
+[MongoDB Documentation](http://docs.mongodb.org/manual/tutorial/create-tailable-cursor/)
+
+##Helpers
+
+###collection()
+
+Sets the querys collection.
+
+```js
+mquery().collection(aCollection)
+```
+
+###then()
+
+Executes the query and returns a promise which will be resolved with the query results or rejected if the query responds with an error.
+
+```js
+mquery().find(..).then(success, error);
+```
+
+This is very useful when combined with [co](https://github.com/visionmedia/co) or [koa](https://github.com/koajs/koa), which automatically resolve promise-like objects for you.
+
+```js
+co(function*(){
+  var doc = yield mquery().findOne({ _id: 499 });
+  console.log(doc); // { _id: 499, name: 'amazing', .. }
+})();
+```
+
+_NOTE_:
+The returned promise is a [bluebird](https://github.com/petkaantonov/bluebird/) promise but this is customizable. If you want to
+use your favorite promise library, simply set `mquery.Promise = YourPromiseConstructor`.
+Your `Promise` must be [promises A+](http://promisesaplus.com/) compliant.
+
+###thunk()
+
+Returns a thunk which when called runs the query's `exec` method passing the results to the callback.
+
+```js
+var thunk = mquery(collection).find({..}).thunk();
+
+thunk(function(err, results) {
+
+})
+```
+
+###merge(object)
+
+Merges other mquery or match condition objects into this one. When an muery instance is passed, its match conditions, field selection and options are merged.
+
+```js
+var drum = mquery({ type: 'drum' }).collection(instruments);
+var redDrum = mqery({ color: 'red' }).merge(drum);
+redDrum.count(function (err, n) {
+  console.log('there are %d red drums', n);
+})
+```
+
+Internally uses `mquery.canMerge` to determine validity.
+
+###setOptions(options)
+
+Sets query options.
+
+```js
+mquery().setOptions({ collection: coll, limit: 20 })
+```
+
+#####options
+
+- [tailable](#tailable) *
+- [sort](#sort) *
+- [limit](#limit) *
+- [skip](#skip) *
+- [maxScan](#maxscan) *
+- [maxTime](#maxtime) *
+- [batchSize](#batchSize) *
+- [comment](#comment) *
+- [snapshot](#snapshot) *
+- [hint](#hint) *
+- [slaveOk](#slaveOk) *
+- [safe](http://docs.mongodb.org/manual/reference/write-concern/): Boolean - passed through to the collection. Setting to `true` is equivalent to `{ w: 1 }`
+- [collection](#collection): the collection to query against
+
+_* denotes a query helper method is also available_
+
+###setTraceFunction(func)
+
+Set a function to trace this query. Useful for profiling or logging.
+
+```js
+function traceFunction (method, queryInfo, query) {
+  console.log('starting ' + method + ' query');
+
+  return function (err, result, millis) {
+    console.log('finished ' + method + ' query in ' + millis + 'ms');
+  };
+}
+
+mquery().setTraceFunction(traceFunction).findOne({name: 'Joe'}, cb);
+```
+
+The trace function is passed (method, queryInfo, query)
+
+- method is the name of the method being called (e.g. findOne)
+- queryInfo contains information about the query:
+ - conditions: query conditions/criteria
+ - options: options such as sort, fields, etc
+ - doc: document being updated
+- query is the query object
+
+The trace function should return a callback function which accepts:
+- err: error, if any
+- result: result, if any
+- millis: time spent waiting for query result
+
+NOTE: stream requests are not traced.
+
+###mquery.setGlobalTraceFunction(func)
+
+Similar to `setTraceFunction()` but automatically applied to all queries.
+
+```js
+mquery.setTraceFunction(traceFunction);
+```
+
+###mquery.canMerge(conditions)
+
+Determines if `conditions` can be merged using `mquery().merge()`.
+
+```js
+var query = mquery({ type: 'drum' });
+var okToMerge = mquery.canMerge(anObject)
+if (okToMerge) {
+  query.merge(anObject);
+}
+```
+
+##mquery.use$geoWithin
+
+MongoDB 2.4 introduced the `$geoWithin` operator which replaces and is 100% backward compatible with `$within`. As of mquery 0.2, we default to using `$geoWithin` for all `within()` calls.
+
+If you are running MongoDB < 2.4 this will be problematic. To force `mquery` to be backward compatible and always use `$within`, set the `mquery.use$geoWithin` flag to `false`.
+
+```js
+mquery.use$geoWithin = false;
+```
+
+##Custom Base Queries
+
+Often times we want custom base queries that encapsulate predefined criteria. With `mquery` this is easy. First create the query you want to reuse and call its `toConstructor()` method which returns a new subclass of `mquery` that retains all options and criteria of the original.
+
+```js
+var greatMovies = mquery(movieCollection).where('rating').gte(4.5).toConstructor();
+
+// use it!
+greatMovies().count(function (err, n) {
+  console.log('There are %d great movies', n);
+});
+
+greatMovies().where({ name: /^Life/ }).select('name').find(function (err, docs) {
+  console.log(docs);
+});
+```
+
+##Validation
+
+Method and options combinations are checked for validity at runtime to prevent creation of invalid query constructs. For example, a `distinct` query does not support specifying options like `hint` or field selection. In this case an error will be thrown so you can catch these mistakes in development.
+
+##Debug support
+
+Debug mode is provided through the use of the [debug](https://github.com/visionmedia/debug) module. To enable:
+
+    DEBUG=mquery node yourprogram.js
+
+Read the debug module documentation for more details.
+
+## General compatibility
+
+#### ObjectIds
+
+`mquery` clones query arguments before passing them to a `collection` method for execution.
+This prevents accidental side-affects to the objects you pass.
+To clone `ObjectIds` we need to make some assumptions.
+
+First, to check if an object is an `ObjectId`, we check its constructors name. If it matches either
+`ObjectId` or `ObjectID` we clone it.
+
+To clone `ObjectIds`, we call its optional `clone` method. If a `clone` method does not exist, we fall
+back to calling `new obj.constructor(obj.id)`. We assume, for compatibility with the
+Node.js driver, that the `ObjectId` instance has a public `id` property and that
+when creating an `ObjectId` instance we can pass that `id` as an argument.
+
+#### Read Preferences
+
+`mquery` supports specifying [Read Preferences]() to control from which MongoDB node your query will read.
+The Read Preferences spec also support specifying tags. To pass tags, some
+drivers (Node.js driver) require passing a special constructor that handles both the read preference and its tags.
+If you need to specify tags, pass an instance of your drivers ReadPreference constructor or roll your own. `mquery` will store whatever you provide and pass later to your collection during execution.
+

+
+# Quick start
+
+## Node.js
+
+    npm install bluebird
+
+Then:
+
+```js
+var Promise = require("bluebird");
+```
+
+## Browsers
+
+There are many ways to use bluebird in browsers:
+
+- Direct downloads
+    - Full build [bluebird.js](https://cdn.jsdelivr.net/bluebird/latest/bluebird.js)
+    - Full build minified [bluebird.min.js](https://cdn.jsdelivr.net/bluebird/latest/bluebird.min.js)
+    - Core build [bluebird.core.js](https://cdn.jsdelivr.net/bluebird/latest/bluebird.core.js)
+    - Core build minified [bluebird.core.min.js](https://cdn.jsdelivr.net/bluebird/latest/bluebird.core.min.js)
+- You may use browserify on the main export
+- You may use the [bower](http://bower.io) package.
+
+When using script tags the global variables `Promise` and `P` (alias for `Promise`) become available.
+
+A [minimal bluebird browser build](#custom-builds) is ≈38.92KB minified*, 11.65KB gzipped and has no external dependencies.
+
+*Google Closure Compiler using Simple.
+
+#### Browser support
+
+Browsers that [implement ECMA-262, edition 3](http://en.wikipedia.org/wiki/Ecmascript#Implementations) and later are supported.
+
+[![Selenium Test Status](https://saucelabs.com/browser-matrix/petka_antonov.svg)](https://saucelabs.com/u/petka_antonov)
+
+**Note** that in ECMA-262, edition 3 (IE7, IE8 etc.) it is not possible to use methods that have keyword names like `.catch` and `.finally`. The [API documentation](API.md) always lists a compatible alternative name that you can use if you need to support these browsers. For example `.catch` is replaced with `.caught` and `.finally` with `.lastly`.
+
+Also, [long stack trace](API.md#promiselongstacktraces---void) support is only available in Chrome, Firefox and Internet Explorer 10+.
+
+After quick start, see [API Reference and examples](API.md)

+
+# What are promises and why should I use them?
+
+You should use promises to turn this:
+
+```js
+fs.readFile("file.json", function(err, val) {
+    if( err ) {
+        console.error("unable to read file");
+    }
+    else {
+        try {
+            val = JSON.parse(val);
+            console.log(val.success);
+        }
+        catch( e ) {
+            console.error("invalid json in file");
+        }
+    }
+});
+```
+
+Into this:
+
+```js
+fs.readFileAsync("file.json").then(JSON.parse).then(function(val) {
+    console.log(val.success);
+})
+.catch(SyntaxError, function(e) {
+    console.error("invalid json in file");
+})
+.catch(function(e) {
+    console.error("unable to read file");
+});
+```
+
+*If you are wondering "there is no `readFileAsync` method on `fs` that returns a promise", see [promisification](API.md#promisification)*
+
+Actually you might notice the latter has a lot in common with code that would do the same using synchronous I/O:
+
+```js
+try {
+    var val = JSON.parse(fs.readFileSync("file.json"));
+    console.log(val.success);
+}
+//Syntax actually not supported in JS but drives the point
+catch(SyntaxError e) {
+    console.error("invalid json in file");
+}
+catch(Error e) {
+    console.error("unable to read file");
+}
+```
+
+And that is the point - being able to have something that is a lot like `return` and `throw` in synchronous code.
+
+You can also use promises to improve code that was written with callback helpers:
+
+
+```js
+//Copyright Plato http://stackoverflow.com/a/19385911/995876
+//CC BY-SA 2.5
+mapSeries(URLs, function (URL, done) {
+    var options = {};
+    needle.get(URL, options, function (error, response, body) {
+        if (error) {
+            return done(error);
+        }
+        try {
+            var ret = JSON.parse(body);
+            return done(null, ret);
+        }
+        catch (e) {
+            done(e);
+        }
+    });
+}, function (err, results) {
+    if (err) {
+        console.log(err);
+    } else {
+        console.log('All Needle requests successful');
+        // results is a 1 to 1 mapping in order of URLs > needle.body
+        processAndSaveAllInDB(results, function (err) {
+            if (err) {
+                return done(err);
+            }
+            console.log('All Needle requests saved');
+            done(null);
+        });
+    }
+});
+```
+
+Is more pleasing to the eye when done with promises:
+
+```js
+Promise.promisifyAll(needle);
+var options = {};
+
+var current = Promise.resolve();
+Promise.map(URLs, function(URL) {
+    current = current.then(function () {
+        return needle.getAsync(URL, options);
+    });
+    return current;
+}).map(function(responseAndBody){
+    return JSON.parse(responseAndBody[1]);
+}).then(function (results) {
+    return processAndSaveAllInDB(results);
+}).then(function(){
+    console.log('All Needle requests saved');
+}).catch(function (e) {
+    console.log(e);
+});
+```
+
+Also promises don't just give you correspondences for synchronous features but can also be used as limited event emitters or callback aggregators.

+# Questions and issues
+
+The [github issue tracker](https://github.com/petkaantonov/bluebird/issues) is **_only_** for bug reports and feature requests. Anything else, such as questions for help in using the library, should be posted in [StackOverflow](http://stackoverflow.com/questions/tagged/bluebird) under tags `promise` and `bluebird`.
+
+# Error handling
+
+This is a problem every promise library needs to handle in some way. Unhandled rejections/exceptions don't really have a good agreed-on asynchronous correspondence. The problem is that it is impossible to predict the future and know if a rejected promise will eventually be handled.
+
+There are two common pragmatic attempts at solving the problem that promise libraries do.
+
+The more popular one is to have the user explicitly communicate that they are done and any unhandled rejections should be thrown, like so:
+
+```js
+download().then(...).then(...).done();
+```
+
+For handling this problem, in my opinion, this is completely unacceptable and pointless. The user must remember to explicitly call `.done` and that cannot be justified when the problem is forgetting to create an error handler in the first place.
+
+The second approach, which is what bluebird by default takes, is to call a registered handler if a rejection is unhandled by the start of a second turn. The default handler is to write the stack trace to `stderr` or `console.error` in browsers. This is close to what happens with synchronous code - your code doesn't work as expected and you open console and see a stack trace. Nice.
+
+Of course this is not perfect, if your code for some reason needs to swoop in and attach error handler to some promise after the promise has been hanging around a while then you will see annoying messages. In that case you can use the `.done()` method to signal that any hanging exceptions should be thrown.
+
+If you want to override the default handler for these possibly unhandled rejections, you can pass yours like so:
+
+```js
+Promise.onPossiblyUnhandledRejection(function(error){
+    throw error;
+});
+```
+
+If you want to also enable long stack traces, call:
+
+```js
+Promise.longStackTraces();
+```
+
+right after the library is loaded.
+
+In node.js use the environment flag `BLUEBIRD_DEBUG`:
+
+```
+BLUEBIRD_DEBUG=1 node server.js
+```
+
+to enable long stack traces in all instances of bluebird.
+
+Long stack traces cannot be disabled after being enabled, and cannot be enabled after promises have already been created. Long stack traces imply a substantial performance penalty, even after using every trick to optimize them.
+
+Long stack traces are enabled by default in the debug build.
+
+#### Expected and unexpected errors
+
+A practical problem with Promises/A+ is that it models Javascript `try-catch` too closely for its own good. Therefore by default promises inherit `try-catch` warts such as the inability to specify the error types that the catch block is eligible for. It is an anti-pattern in every other language to use catch-all handlers because they swallow exceptions that you might not know about.
+
+Now, Javascript does have a perfectly fine and working way of creating error type hierarchies. It is still quite awkward to use them with the built-in `try-catch` however:
+
+```js
+try {
+    //code
+}
+catch(e) {
+    if( e instanceof WhatIWantError) {
+        //handle
+    }
+    else {
+        throw e;
+    }
+}
+```
+
+Without such checking, unexpected errors would be silently swallowed. However, with promises, bluebird brings the future (hopefully) here now and extends the `.catch` to [accept potential error type eligibility](API.md#catchfunction-errorclass-function-handler---promise).
+
+For instance here it is expected that some evil or incompetent entity will try to crash our server from `SyntaxError` by providing syntactically invalid JSON:
+
+```js
+getJSONFromSomewhere().then(function(jsonString) {
+    return JSON.parse(jsonString);
+}).then(function(object) {
+    console.log("it was valid json: ", object);
+}).catch(SyntaxError, function(e){
+    console.log("don't be evil");
+});
+```
+
+Here any kind of unexpected error will be automatically reported on `stderr` along with a stack trace because we only register a handler for the expected `SyntaxError`.
+
+Ok, so, that's pretty neat. But actually not many libraries define error types and it is in fact a complete ghetto out there with ad hoc strings being attached as some arbitrary property name like `.name`, `.type`, `.code`, not having any property at all or even throwing strings as errors and so on. So how can we still listen for expected errors?
+
+Bluebird defines a special error type `OperationalError` (you can get a reference from `Promise.OperationalError`). This type of error is given as rejection reason by promisified methods when
+their underlying library gives an untyped, but expected error. Primitives such as strings, and error objects that are directly created like `new Error("database didn't respond")` are considered untyped.
+
+Example of such library is the node core library `fs`. So if we promisify it, we can catch just the errors we want pretty easily and have programmer errors be redirected to unhandled rejection handler so that we notice them:
+
+```js
+//Read more about promisification in the API Reference:
+//API.md
+var fs = Promise.promisifyAll(require("fs"));
+
+fs.readFileAsync("myfile.json").then(JSON.parse).then(function (json) {
+    console.log("Successful json");
+}).catch(SyntaxError, function (e) {
+    console.error("file contains invalid json");
+}).catch(Promise.OperationalError, function (e) {
+    console.error("unable to read file, because: ", e.message);
+});
+```
+
+The last `catch` handler is only invoked when the `fs` module explicitly used the `err` argument convention of async callbacks to inform of an expected error. The `OperationalError` instance will contain the original error in its `.cause` property but it does have a direct copy of the `.message` and `.stack` too. In this code any unexpected error - be it in our code or the `fs` module - would not be caught by these handlers and therefore not swallowed.
+
+Since a `catch` handler typed to `Promise.OperationalError` is expected to be used very often, it has a neat shorthand:
+
+```js
+.error(function (e) {
+    console.error("unable to read file, because: ", e.message);
+});
+```
+
+See [API documentation for `.error()`](API.md#error-rejectedhandler----promise)
+
+Finally, Bluebird also supports predicate-based filters. If you pass a
+predicate function instead of an error type, the predicate will receive
+the error as an argument. The return result will be used to determine whether
+the error handler should be called.
+
+Predicates should allow for very fine grained control over caught errors:
+pattern matching, error typesets with set operations and many other techniques
+can be implemented on top of them.
+
+Example of using a predicate-based filter:
+
+```js
+var Promise = require("bluebird");
+var request = Promise.promisify(require("request"));
+
+function clientError(e) {
+    return e.code >= 400 && e.code < 500;
+}
+
+request("http://www.google.com").then(function(contents){
+    console.log(contents);
+}).catch(clientError, function(e){
+   //A client error like 400 Bad Request happened
+});
+```
+
+**Danger:** The JavaScript language allows throwing primitive values like strings. Throwing primitives can lead to worse or no stack traces. Primitives [are not exceptions](http://www.devthought.com/2011/12/22/a-string-is-not-an-error/). You should consider always throwing Error objects when handling exceptions.
+
+

+
+#### How do long stack traces differ from e.g. Q?
+
+Bluebird attempts to have more elaborate traces. Consider:
+
+```js
+Error.stackTraceLimit = 25;
+Q.longStackSupport = true;
+Q().then(function outer() {
+    return Q().then(function inner() {
+        return Q().then(function evenMoreInner() {
+            a.b.c.d();
+        }).catch(function catcher(e){
+            console.error(e.stack);
+        });
+    })
+});
+```
+
+You will see
+
+    ReferenceError: a is not defined
+        at evenMoreInner (:7:13)
+    From previous event:
+        at inner (:6:20)
+
+Compare to:
+
+```js
+Error.stackTraceLimit = 25;
+Promise.longStackTraces();
+Promise.resolve().then(function outer() {
+    return Promise.resolve().then(function inner() {
+        return Promise.resolve().then(function evenMoreInner() {
+            a.b.c.d();
+        }).catch(function catcher(e){
+            console.error(e.stack);
+        });
+    });
+});
+```
+
+    ReferenceError: a is not defined
+        at evenMoreInner (:7:13)
+    From previous event:
+        at inner (:6:36)

+
+# Development
+
+For development tasks such as running benchmarks or testing, you need to clone the repository and install dev-dependencies.
+
+Install [node](http://nodejs.org/) and [npm](https://npmjs.org/)
+
+    git clone git@github.com:petkaantonov/bluebird.git
+    cd bluebird
+    npm install
+
+## Testing
+
+To run all tests, run
+
+    node tools/test
+
+If you need to run generator tests run the `tool/test.js` script with `--harmony` argument and node 0.11+:
+
+    node-dev --harmony tools/test
+
+You may specify an individual test file to run with the `--run` script flag:
+
+    node tools/test --run=cancel.js
+
+
+This enables output from the test and may give a better idea where the test is failing. The parameter to `--run` can be any file name located in `test/mocha` folder.
+
+#### Testing in browsers
+
+To run the test in a browser instead of node, pass the flag `--browser` to the test tool
+
+    node tools/test --run=cancel.js --browser
+
+This will automatically create a server (default port 9999) and open it in your default browser once the tests have been compiled.
+
+Keep the test tab active because some tests are timing-sensitive and will fail if the browser is throttling timeouts. Chrome will do this for example when the tab is not active.
+
+#### Supported options by the test tool
+
+The value of boolean flags is determined by presence, if you want to pass false value for a boolean flag, use the `no-`-prefix e.g. `--no-browser`.
+
+ - `--run=String` - Which tests to run (or compile when testing in browser). Default `"all"`. Can also be a glob string (relative to ./test/mocha folder).
+ - `--cover=String`. Create code coverage using the String as istanbul reporter. Coverage is created in the ./coverage folder. No coverage is created by default, default reporter is `"html"` (use `--cover` to use default reporter).
+ - `--browser` - Whether to compile tests for browsers. Default `false`.
+ - `--port=Number` - Port where local server is hosted when testing in browser. Default `9999`
+ - `--execute-browser-tests` - Whether to execute the compiled tests for browser when using `--browser`. Default `true`.
+ - `--open-browser` - Whether to open the default browser when executing browser tests. Default `true`.
+ - `--fake-timers` - Whether to use fake timers (`setTimeout` etc) when running tests in node. Default `true`.
+ - `--js-hint` - Whether to run JSHint on source files. Default `true`.
+ - `--saucelabs` - Whether to create a tunnel to sauce labs and run tests in their VMs instead of your browser when compiling tests for browser. Default `false`.
+
+## Benchmarks
+
+To run a benchmark, run the given command for a benchmark while on the project root. Requires bash (on windows the mingw32 that comes with git works fine too).
+
+Node 0.11.2+ is required to run the generator examples.
+
+### 1\. DoxBee sequential
+
+Currently the most relevant benchmark is @gorkikosev's benchmark in the article [Analysis of generators and other async patterns in node](http://spion.github.io/posts/analysis-generators-and-other-async-patterns-node.html). The benchmark emulates a situation where n amount of users are making a request in parallel to execute some mixed async/sync action. The benchmark has been modified to include a warm-up phase to minimize any JITing during timed sections.
+
+Command: `bench doxbee`
+
+### 2\. Made-up parallel
+
+This made-up scenario runs 15 shimmed queries in parallel.
+
+Command: `bench parallel`
+
+## Custom builds
+
+Custom builds for browsers are supported through a command-line utility.

+
+Make sure you have cloned the repo somewhere and did `npm install` successfully.
+
+After that you can run:
+
+    node tools/build --features="core"
+
+
+The above builds the most minimal build you can get. You can add more features separated by spaces from the above list:
+
+    node tools/build --features="core filter map reduce"
+
+The custom build file will be found from `/js/browser/bluebird.js`. It will have a comment that lists the disabled and enabled features.
+
+Note that the build leaves the `/js/main` etc folders with same features so if you use the folder for node.js at the same time, don't forget to build
+a full version afterwards (after having taken a copy of the bluebird.js somewhere):
+
+    node tools/build --debug --main --zalgo --browser --minify
+
+#### Supported options by the build tool
+
+The value of boolean flags is determined by presence, if you want to pass false value for a boolean flag, use the `no-`-prefix e.g. `--no-debug`.
+
+ - `--main` - Whether to build the main build. The main build is placed at `js/main` directory. Default `false`.
+ - `--debug` - Whether to build the debug build. The debug build is placed at `js/debug` directory. Default `false`.
+ - `--zalgo` - Whether to build the zalgo build. The zalgo build is placed at `js/zalgo` directory. Default `false`.
+ - `--browser` - Whether to compile the browser build. The browser build file is placed at `js/browser/bluebird.js` Default `false`.
+ - `--minify` - Whether to minify the compiled browser build. The minified browser build file is placed at `js/browser/bluebird.min.js` Default `true`.
+ - `--features=String` - See [custom builds](#custom-builds)
+
+

+
+## For library authors
+
+Building a library that depends on bluebird? You should know about a few features.
+
+If your library needs to do something obtrusive like adding or modifying methods on the `Promise` prototype, uses long stack traces or uses a custom unhandled rejection handler then... that's totally ok as long as you don't use `require("bluebird")`. Instead you should create a file
+that creates an isolated copy. For example, creating a file called `bluebird-extended.js` that contains:
+
+```js
+                //NOTE the function call right after
+module.exports = require("bluebird/js/main/promise")();
+```
+
+Your library can then use `var Promise = require("bluebird-extended");` and do whatever it wants with it. Then if the application or other library uses their own bluebird promises they will all play well together because of Promises/A+ thenable assimilation magic.
+
+You should also know about [`.nodeify()`](API.md#nodeifyfunction-callback---promise) which makes it easy to provide a dual callback/promise API.
+
+

+
+## What is the sync build?
+
+You may now use sync build by:
+
+    var Promise = require("bluebird/zalgo");
+
+The sync build is provided to see how forced asynchronity affects benchmarks. It should not be used in real code due to the implied hazards.
+
+The normal async build gives Promises/A+ guarantees about asynchronous resolution of promises. Some people think this affects performance or just plain love their code having a possibility
+of stack overflow errors and non-deterministic behavior.
+
+The sync build skips the async call trampoline completely, e.g code like:
+
+    async.invoke( this.fn, this, val );
+
+Appears as this in the sync build:
+
+    this.fn(val);
+
+This should pressure the CPU slightly less and thus the sync build should perform better. Indeed it does, but only marginally. The biggest performance boosts are from writing efficient Javascript, not from compromising determinism.
+
+Note that while some benchmarks are waiting for the next event tick, the CPU is actually not in use during that time. So the resulting benchmark result is not completely accurate because on node.js you only care about how much the CPU is taxed. Any time spent on CPU is time the whole process (or server) is paralyzed. And it is not graceful like it would be with threads.
+
+
+```js
+var cache = new Map(); //ES6 Map or DataStructures/Map or whatever...
+function getResult(url) {
+    var resolver = Promise.pending();
+    if (cache.has(url)) {
+        resolver.resolve(cache.get(url));
+    }
+    else {
+        http.get(url, function(err, content) {
+            if (err) resolver.reject(err);
+            else {
+                cache.set(url, content);
+                resolver.resolve(content);
+            }
+        });
+    }
+    return resolver.promise;
+}
+
+
+
+//The result of console.log is truly random without async guarantees
+function guessWhatItPrints( url ) {
+    var i = 3;
+    getResult(url).then(function(){
+        i = 4;
+    });
+    console.log(i);
+}
+```

+ - Fix promises created in [`disposers`](API#disposerfunction-disposer---disposer) not having proper long stack trace context
+ - Fix [`Promise.join`](API.md#promisejoinpromisethenablevalue-promises-function-handler---promise) sometimes passing the passed in callback function as the last argument to itself.
+
+Misc:
+
+ - Reduce minified full browser build file size by not including unused code generation functionality.
+ - Major internal refactoring related to testing code and source code file layout

+Bugfixes:
+
+ - Fix long stack trace stiching consistency when rejected from thenables
+
+## 2.8.0 (2015-01-19)

+#What's new in 2.0
+
+- [Resource management](API.md#resource-management) - never leak resources again
+- [Promisification](API.md#promisification) on steroids - entire modules can now be promisified with one line of code
+- [`.map()`](API.md#mapfunction-mapper--object-options---promise), [`.each()`](API.md#eachfunction-iterator---promise), [`.filter()`](API.md#filterfunction-filterer--object-options---promise), [`.reduce()`](API.md#reducefunction-reducer--dynamic-initialvalue---promise) reimagined from simple sugar to powerful concurrency coordination tools
+- [API Documentation](API.md) has been reorganized and more elaborate examples added
+- Deprecated [progression](#progression-migration) and [deferreds](#deferred-migration)
+- Improved performance and readability
+
+Features:
+
+- Added [`using()`](API.md#promiseusingpromisedisposer-promise-promisedisposer-promise--function-handler---promise) and [`disposer()`](API.md#disposerfunction-disposer---disposer)
+- [`.map()`](API.md#mapfunction-mapper--object-options---promise) now calls the handler as soon as items in the input array become fulfilled
+- Added a concurrency option to [`.map()`](API.md#mapfunction-mapper--object-options---promise)
+- [`.filter()`](API.md#filterfunction-filterer--object-options---promise) now calls the handler as soon as items in the input array become fulfilled
+- Added a concurrency option to [`.filter()`](API.md#filterfunction-filterer--object-options---promise)
+- [`.reduce()`](API.md#reducefunction-reducer--dynamic-initialvalue---promise) now calls the handler as soon as items in the input array become fulfilled, but in-order
+- Added [`.each()`](API.md#eachfunction-iterator---promise)
+- [`Promise.resolve()`](API.md#promiseresolvedynamic-value---promise) behaves like `Promise.cast`. `Promise.cast` deprecated.
+- [Synchronous inspection](API.md#synchronous-inspection): Removed `.inspect()`, added [`.value()`](API.md#value---dynamic) and [`.reason()`](API.md#reason---dynamic)
+- [`Promise.join()`](API.md#promisejoinpromisethenablevalue-promises-function-handler---promise) now takes a function as the last argument
+- Added [`Promise.setScheduler()`](API.md#promisesetschedulerfunction-scheduler---void)
+- [`.cancel()`](API.md#cancelerror-reason---promise) supports a custom cancellation reason
+- [`.timeout()`](API.md#timeoutint-ms--string-message---promise) now cancels the promise instead of rejecting it
+- [`.nodeify()`](API.md#nodeifyfunction-callback--object-options---promise) now supports passing multiple success results when mapping promises to nodebacks
+- Added `suffix` and `filter` options to [`Promise.promisifyAll()`](API.md#promisepromisifyallobject-target--object-options---object)
+
+Breaking changes:
+
+- Sparse array holes are not skipped by collection methods but treated as existing elements with `undefined` value
+- `.map()` and `.filter()` do not call the given mapper or filterer function in any specific order
+- Removed the `.inspect()` method
+- Yielding an array from a coroutine is not supported by default. You can use [`coroutine.addYieldHandler()`](API.md#promisecoroutineaddyieldhandlerfunction-handler---void) to configure the old behavior (or any behavior you want).
+- [`.any()`](API.md#any---promise) and [`.some()`](API.md#someint-count---promise) no longer use an array as the rejection reason. [`AggregateError`](API.md#aggregateerror) is used instead.

+
+Features:
+
+ - Possibly unhandled rejection handler will always get a stack trace, even if the rejection or thrown error was not an error
+ - Unhandled rejections are tracked per promise, not per error. So if you create multiple branches from a single ancestor and that ancestor gets rejected, each branch with no error handler with the end will cause a possibly unhandled rejection handler invocation

+
+Features:

+# debug
+
+  tiny node.js debugging utility modelled after node core's debugging technique.
+
+## Installation
+
+```bash
+$ npm install debug
+```
+
+## Usage
+
+ With `debug` you simply invoke the exported function to generate your debug function, passing it a name which will determine if a noop function is returned, or a decorated `console.error`, so all of the `console` format string goodies you're used to work fine. A unique color is selected per-function for visibility.
+
+Example _app.js_:
+
+```js
+var debug = require('debug')('http')
+  , http = require('http')
+  , name = 'My App';
+
+// fake app
+
+debug('booting %s', name);
+
+http.createServer(function(req, res){
+  debug(req.method + ' ' + req.url);
+  res.end('hello\n');
+}).listen(3000, function(){
+  debug('listening');
+});
+
+// fake worker of some kind
+
+require('./worker');
+```
+
+Example _worker.js_:
+
+```js
+var debug = require('debug')('worker');
+
+setInterval(function(){
+  debug('doing some work');
+}, 1000);
+```
+
+ The __DEBUG__ environment variable is then used to enable these based on space or comma-delimited names. Here are some examples:
+
+  ![debug http and worker](http://f.cl.ly/items/18471z1H402O24072r1J/Screenshot.png)
+
+  ![debug worker](http://f.cl.ly/items/1X413v1a3M0d3C2c1E0i/Screenshot.png)
+
+#### Windows note
+
+ On Windows the environment variable is set using the `set` command.
+
+ ```cmd
+ set DEBUG=*,-not_this
+ ```
+
+Then, run the program to be debugged as usual.
+
+## Millisecond diff
+
+  When actively developing an application it can be useful to see when the time spent between one `debug()` call and the next. Suppose for example you invoke `debug()` before requesting a resource, and after as well, the "+NNNms" will show you how much time was spent between calls.
+
+  ![](http://f.cl.ly/items/2i3h1d3t121M2Z1A3Q0N/Screenshot.png)
+
+  When stdout is not a TTY, `Date#toUTCString()` is used, making it more useful for logging the debug information as shown below:
+
+  ![](http://f.cl.ly/items/112H3i0e0o0P0a2Q2r11/Screenshot.png)
+
+## Conventions
+
+ If you're using this in one or more of your libraries, you _should_ use the name of your library so that developers may toggle debugging as desired without guessing names. If you have more than one debuggers you _should_ prefix them with your library name and use ":" to separate features. For example "bodyParser" from Connect would then be "connect:bodyParser".
+
+## Wildcards
+
+  The `*` character may be used as a wildcard. Suppose for example your library has debuggers named "connect:bodyParser", "connect:compress", "connect:session", instead of listing all three with `DEBUG=connect:bodyParser,connect:compress,connect:session`, you may simply do `DEBUG=connect:*`, or to run everything using this module simply use `DEBUG=*`.
+
+  You can also exclude specific debuggers by prefixing them with a "-" character.  For example, `DEBUG=*,-connect:*` would include all debuggers except those starting with "connect:".
+
+## Browser support
+
+  Debug works in the browser as well, currently persisted by `localStorage`. Consider the situation shown below where you have `worker:a` and `worker:b`, and wish to debug both. Somewhere in the code on your page, include:
+
+```js
+window.myDebug = require("debug");
+```
+
+  ("debug" is a global object in the browser so we give this object a different name.) When your page is open in the browser, type the following in the console:
+
+```js
+myDebug.enable("worker:*")
+```
+
+  Refresh the page. Debug output will continue to be sent to the console until it is disabled by typing `myDebug.disable()` in the console.
+
+```js
+a = debug('worker:a');
+b = debug('worker:b');
+
+setInterval(function(){
+  a('doing some work');
+}, 1000);
+
+setInterval(function(){
+  b('doing some work');
+}, 1200);
+```
+
+#### Web Inspector Colors
+
+  Colors are also enabled on "Web Inspectors" that understand the `%c` formatting
+  option. These are WebKit web inspectors, Firefox ([since version
+  31](https://hacks.mozilla.org/2014/05/editable-box-model-multiple-selection-sublime-text-keys-much-more-firefox-developer-tools-episode-31/))
+  and the Firebug plugin for Firefox (any version).
+
+  Colored output looks something like:
+
+  ![](https://cloud.githubusercontent.com/assets/71256/3139768/b98c5fd8-e8ef-11e3-862a-f7253b6f47c6.png)
+
+### stderr vs stdout
+
+You can set an alternative logging method per-namespace by overriding the `log` method on a per-namespace or globally:
+
+Example _stdout.js_:
+
+```js
+var debug = require('debug');
+var error = debug('app:error');
+
+// by default stderr is used
+error('goes to stderr!');
+
+var log = debug('app:log');
+// set this namespace to log via console.log
+log.log = console.log.bind(console); // don't forget to bind to console!
+log('goes to stdout');
+error('still goes to stderr!');
+
+// set all output to go via console.info
+// overrides all per-namespace log settings
+debug.log = console.info.bind(console);
+error('now goes to stdout via console.info');
+log('still goes to stdout, but via console.info now');
+```
+
+### Save debug output to a file
+
+You can save all debug statements to a file by piping them.
+
+Example:
+
+```bash
+$ DEBUG_FD=3 node your-app.js 3> whatever.log
+```

-
-Ever find yourself doing math in your head or writing `1000 * 60 * 60 …`?
-Don't want to add obstrusive `Number` prototype extensions to your reusable
-/ distributable modules and projects?
-
-`ms` is a tiny utility that you can leverage when your application needs to
-accept a number of miliseconds as a parameter.
-
-If a number is supplied to `ms`, it returns it immediately (e.g:
-If a string that contains the number is supplied, it returns it immediately as
-a number (e.g: it returns `100` for `'100'`).
-
-However, if you pass a string with a number and a valid unit, hte number of
-equivalent ms is returned.
+# ms.js: miliseconds conversion utility
 
 ```js
+ms('2 days')  // 172800000
 ms('1d')      // 86400000
 ms('10h')     // 36000000
+ms('2.5 hrs') // 9000000
 ms('2h')      // 7200000
 ms('1m')      // 60000
-ms('5ms')     // 5000
-ms('100')     // '100'
-ms(100)       // 100
+ms('5s')      // 5000
+ms('100')     // 100
 ```
 
-## How to use
-
-### Node
-
 ```js
-require('ms')
+ms(60000)             // "1m"
+ms(2 * 60000)         // "2m"
+ms(ms('10 hours'))    // "10h"
 ```
 
-### Browser
-
-```html
-
+```js
+ms(60000, { long: true })             // "1 minute"
+ms(2 * 60000, { long: true })         // "2 minutes"
+ms(ms('10 hours'), { long: true })    // "10 hours"
