+# engine.io-parser
+
+[![Build Status](https://secure.travis-ci.org/socketio/engine.io-parser.svg)](http://travis-ci.org/socketio/engine.io-parser)
+[![NPM version](https://badge.fury.io/js/engine.io-parser.svg)](http://badge.fury.io/js/engine.io-parser)
+
+This is the JavaScript parser for the engine.io protocol encoding,
+shared by both
+[engine.io-client](https://github.com/socketio/engine.io-client) and
+[engine.io](https://github.com/socketio/engine.io).
+
+## How to use
+
+### Standalone
+
+The parser can encode/decode packets, payloads, and payloads as binary
+with the following methods: `encodePacket`, `decodePacket`, `encodePayload`,
+`decodePayload`, `encodePayloadAsBinary`, `decodePayloadAsBinary`.
+
+The browser-side parser also includes `encodePayloadAsArrayBuffer` and `encodePayloadAsBlob`.
+
+Example:
+
+```js
+var parser = require('engine.io-parser');
+
+var data = new Buffer(5);
+for (var i = 0; i < data.length; i++) { data[i] = i; }
+
+parser.encodePacket({ type: 'message', data: data }, function(encoded) {
+  var decodedData = parser.decodePacket(encoded); // { type: 'message', data: data }
+});
+```
+
+### With browserify
+
+Engine.IO Parser is a commonjs module, which means you can include it by using
+`require` on the browser and package using [browserify](http://browserify.org/):
+
+1. install the parser package
+
+    ```shell
+    npm install engine.io-parser
+    ```
+
+1. write your app code
+
+    ```js
+    var parser = require('engine.io-parser');
+
+    var testBuffer = new Int8Array(10);
+    for (var i = 0; i < testBuffer.length; i++) testBuffer[i] = i;
+
+    var packets = [{ type: 'message', data: testBuffer.buffer }, { type: 'message', data: 'hello' }];
+
+    parser.encodePayload(packets, function(encoded) {
+      parser.decodePayload(encoded,
+        function(packet, index, total) {
+          var isLast = index + 1 == total;
+          if (!isLast) {
+            var buffer = new Int8Array(packet.data); // testBuffer
+          } else {
+            var message = packet.data; // 'hello'
+          }
+        });
+    });
+    ```
+
+1. build your app bundle
+
+    ```bash
+    $ browserify app.js > bundle.js
+    ```
+
+1. include on your page
+
+    ```html
+    <script src="/path/to/bundle.js"></script>
+    ```
+
+## Features
+
+- Runs on browser and node.js seamlessly
+- Runs inside HTML5 WebWorker
+- Can encode and decode packets
+  - Encodes from/to ArrayBuffer or Blob when in browser, and Buffer or ArrayBuffer in Node
+
+## API
+
+Note: `cb(type)` means the type is a callback function that contains a parameter of type `type` when called.
+
+### Node
+
+- `encodePacket`
+    - Encodes a packet.
+    - **Parameters**
+      - `Object`: the packet to encode, has `type` and `data`.
+        - `data`: can be a `String`, `Number`, `Buffer`, `ArrayBuffer`
+      - `Boolean`: optional, binary support
+      - `Function`: callback, returns the encoded packet (`cb(String)`)
+- `decodePacket`
+    - Decodes a packet. Data also available as an ArrayBuffer if requested.
+    - Returns data as `String` or (`Blob` on browser, `ArrayBuffer` on Node)
+    - **Parameters**
+      - `String` | `ArrayBuffer`: the packet to decode, has `type` and `data`
+      - `String`: optional, the binary type
+
+- `encodeBase64Packet`
+    - Encodes a packet with binary data in a base64 string (`String`)
+    - **Parameters**
+      - `Object`: the packet to encode, has `type` and `data`
+      - `Function`: callback, returns the base64 encoded message (`cb(String)`)
+- `decodeBase64Packet`
+    - Decodes a packet encoded in a base64 string.
+    - **Parameters**
+      - `String`: the base64 encoded message
+      - `String`: optional, the binary type
+
+- `encodePayload`
+    - Encodes multiple messages (payload).
+    - If any contents are binary, they will be encoded as base64 strings. Base64
+      encoded strings are marked with a b before the length specifier
+    - **Parameters**
+      - `Array`: an array of packets
+      - `Boolean`: optional, binary support
+      - `Function`: callback, returns the encoded payload (`cb(String)`)
+- `decodePayload`
+    - Decodes data when a payload is maybe expected. Possible binary contents are
+      decoded from their base64 representation.
+    - **Parameters**
+      - `String`: the payload
+      - `String`: optional, the binary type
+      - `Function`: callback, returns (cb(`Object`: packet, `Number`:packet index, `Number`:packet total))
+
+- `encodePayloadAsBinary`
+    - Encodes multiple messages (payload) as binary.
+    - **Parameters**
+      - `Array`: an array of packets
+      - `Function`: callback, returns the encoded payload (`cb(Buffer)`)
+- `decodePayloadAsBinary`
+    - Decodes data when a payload is maybe expected. Strings are decoded by
+      interpreting each byte as a key code for entries marked to start with 0. See
+      description of encodePayloadAsBinary.
+    - **Parameters**
+      - `Buffer`: the buffer
+      - `String`: optional, the binary type
+      - `Function`: callback, returns the decoded packet (`cb(Object)`)
+
+### Browser
+
+- `encodePayloadAsArrayBuffer`
+    - Encodes multiple messages (payload) as binary.
+    - **Parameters**
+      - `Array`: an array of packets
+      - `Function`: callback, returns the encoded payload (`cb(ArrayBuffer)`)
+- `encodePayloadAsBlob`
+    - Encodes multiple messages (payload) as blob.
+    - **Parameters**
+      - `Array`: an array of packets
+      - `Function`: callback, returns the encoded payload (`cb(Blob)`)
+
+## Tests
+
+Standalone tests can be run with `make test` which will run both node.js and browser tests.
+
+Browser tests are run using [zuul](https://github.com/defunctzombie/zuul).
+(You must have zuul setup with a saucelabs account.)
+
+You can run the tests locally using the following command:
+
+```
+./node_modules/.bin/zuul --local 8080 -- test/index.js
+```
+
+## Support
+
+The support channels for `engine.io-parser` are the same as `socket.io`:
+  - irc.freenode.net **#socket.io**
+  - [Google Groups](http://groups.google.com/group/socket_io)
+  - [Website](http://socket.io)
+
+## Development

+repository:
+
+```bash
+git clone git://github.com/LearnBoost/engine.io-parser.git
+```
+
