A simple static file server middleware that works with both Express and Flatiron


A simple static file server middleware. Use it with a raw http server, express/connect, or flatiron/union!


var http = require('http');
var express = require('express');
var ecstatic = require('ecstatic');
var app = express();
app.use(ecstatic({ root: __dirname + '/public' }));
console.log('Listening on :8080');
var union = require('union');
var ecstatic = require('ecstatic');
  before: [
    ecstatic({ root: __dirname + '/public' }),
console.log('Listening on :8080');
var http = require('http');
var ecstatic = require('ecstatic');
  ecstatic({ root: __dirname + '/public' })
console.log('Listening on :8080');

To allow fall through to your custom routes:

ecstatic({ root: __dirname + '/public', handleError: false })


Pass ecstatic an options hash, and it will return your middleware!

var opts = {
             root          : __dirname + '/public',
             baseDir       : '/',
             cache         : 3600,
             showDir       : true,
             autoIndex     : false,
             humanReadable : true,
             si            : false,
             defaultExt    : 'html',
             gzip          : false,
             serverHeader  : true

If opts is a string, the string is assigned to the root folder and all other options are set to their defaults.

opts.root is the directory you want to serve up.

opts.baseDir is / by default, but can be changed to allow your static files to be served off a specific route. For example, if opts.baseDir === "blog" and opts.root = "./public", requests for localhost:8080/blog/index.html will resolve to ./public/index.html.

Customize cache control with opts.cache , if it is a number then it will set max-age in seconds. Other wise it will pass through directly to cache-control. Time defaults to 3600 s (ie, 1 hour).

Turn off directory listings with opts.showDir === false. Defaults to true.

If showDir is enabled, add human-readable file sizes. Defaults to true. Aliases are humanreadable and human-readable.

If showDir and humanReadable are enabled, print file sizes with base 1000 instead of base 1024. Name is inferred from cli options for ls. Aliased to index, the equivalent option in Apache.

Serve /path/index.html when /path/ is requested. Turn off autoIndexing with opts.autoIndex === false. Defaults to true.

Turn on default file extensions with opts.defaultExt. If opts.defaultExt is true, it will default to html. For example if you want a request to /a-file to resolve to ./public/a-file.html, set this to true. If you want /a-file to resolve to ./public/a-file.json instead, set opts.defaultExt to json.

Set opts.gzip === true in order to turn on "gzip mode," wherein ecstatic will serve ./public/some-file.js.gz in place of ./public/some-file.js when the gzipped version exists and ecstatic determines that the behavior is appropriate.

Set opts.serverHeader to false in order to turn off setting the Server header on all responses served by ecstatic.

Set opts.contentType in order to change default Content-Type header value. Defaults to application/octet-stream.

Turn off handleErrors to allow fall-through with opts.handleError === false, Defaults to true.

This works more or less as you'd expect.

This returns another middleware which will attempt to show a directory view. Turning on auto-indexing is roughly equivalent to adding this middleware after an ecstatic middleware with autoindexing disabled.

to start a standalone static http server, run npm install -g ecstatic and then run ecstatic [dir?] [options] --port PORT all options work as above, passed in optimist style. port defaults to 8000. If a dir or --root dir argument is not passed, ecsatic will serve the current dir.


Ecstatic has a fairly extensive test suite. You can run it with:

$ npm test


Without outside contributions, ecstatic would wither and die! Before contributing, take a quick look at the contributing guidelines in ./ . They're relatively painless, I promise.
