serve-static

Install

$ npm install serve-static

API

var serveStatic = require('serve-static')

serveStatic(root, options)

Create a new middleware function to serve files from within a given root directory. The file to serve will be determined by combining req.url with the provided root directory. When a file is not found, instead of sending a 404 response, this module will instead call next() to move on to the next middleware, allowing for stacking and fall-backs.

Options

dotfiles

Set how "dotfiles" are treated when encountered. A dotfile is a file or directory that begins with a dot ("."). Note this check is done on the path itself without checking if the path actually exists on the disk. If root is specified, only the dotfiles above the root are checked (i.e. the root itself can be within a dotfile when when set to "deny").

The default value is 'ignore'.

• 'allow' No special treatment for dotfiles.
• 'deny' Send a 403 for any request for a dotfile.
• 'ignore' Pretend like the dotfile does not exist and call next().

etag

Enable or disable etag generation, defaults to true.

extensions

Set file extension fallbacks. When set, if a file is not found, the given extensions will be added to the file name and search for. The first that exists will be served. Example: ['html', 'htm'].

The default value is false.

index

By default this module will send "index.html" files in response to a request on a directory. To disable this set false or to supply a new index pass a string or an array in preferred order.

lastModified

Enable or disable Last-Modified header, defaults to true. Uses the file system's last modified value.

maxAge

Provide a max-age in milliseconds for http caching, defaults to 0. This can also be a string accepted by the ms module.

redirect

Redirect to trailing "/" when the pathname is a dir. Defaults to true.

setHeaders

Function to set custom headers on response. Alterations to the headers need to occur synchronously. The function is called as fn(res, path, stat), where the arguments are:

• res the response object
• path the file path that is being sent
• stat the stat object of the file that is being sent

Examples

Serve files with vanilla node.js http server

var finalhandler = require('finalhandler')
var http = require('http')
var serveStatic = require('serve-static')

// Serve up public/ftp folder
var serve = serveStatic('public/ftp', {'index': ['index.html', 'index.htm']})

// Create server
var server = http.createServer(function(req, res){
  var done = finalhandler(req, res)
  serve(req, res, done)
})

// Listen
server.listen(3000)

Serve all files as downloads

var contentDisposition = require('content-disposition')
var finalhandler = require('finalhandler')
var http = require('http')
var serveStatic = require('serve-static')

// Serve up public/ftp folder
var serve = serveStatic('public/ftp', {
  'index': false,
  'setHeaders': setHeaders
})

// Set header to force download
function setHeaders(res, path) {
  res.setHeader('Content-Disposition', contentDisposition(path))
}

// Create server
var server = http.createServer(function(req, res){
  var done = finalhandler(req, res)
  serve(req, res, done)
})

// Listen
server.listen(3000)

Serving using express

var connect = require('connect')
var serveStatic = require('serve-static')

var app = connect()

app.use(serveStatic('public/ftp', {'index': ['default.html', 'default.htm']}))
app.listen(3000)
