A static file server middleware that works with core http or Express

Ecstatic

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

Examples:

express 3.0.x

var http = require('http');
var express = require('express');
var ecstatic = require('ecstatic');

var app = express();
app.use(ecstatic({ root: __dirname + '/public' }));
http.createServer(app).listen(8080);

console.log('Listening on :8080');

stock http server

var http = require('http');
var ecstatic = require('ecstatic');

http.createServer(
  ecstatic({ root: __dirname + '/public' })
).listen(8080);

console.log('Listening on :8080');

fall through

To allow fall through to your custom routes:

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

API:

ecstatic(opts);

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

var opts = {
             root               : __dirname + '/public',
             port               : 8000,
             baseDir            : '/',
             cache              : 3600,
             showDir            : true,
             showDotfiles       : true,
             autoIndex          : false,
             humanReadable      : true,
             headers            : {},
             si                 : false,
             defaultExt         : 'html',
             gzip               : false,
             serverHeader       : true,
             contentType        : 'application/octet-stream',
             mimeTypes          : undefined,
             handleOptionsMethod: false
           }

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

opts.root

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

opts.port

opts.port is the port you want ecstatic to listen to. Defaults to 8000.

opts.baseDir

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.

opts.cache

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).

If it is a function, it will be executed on every request, and passed the pathname. Whatever it returns, string or number, will be used as the cache control header like above.

opts.showDir

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

opts.showDotfiles

Exclude dotfiles from directory listings with opts.showDotfiles === false. Defaults to true.

opts.humanReadable

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

opts.headers

Set headers on every response. opts.headers can be an object mapping string header names to string header values, a colon (:) separated string, or an array of colon separated strings.

opts.H and opts.header are aliased to opts.headers so that you can use -H and --header options to set headers on the command-line like curl:

$ ecstatic ./public -p 5000 -H 'Access-Control-Allow-Origin: *'

opts.si

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.

opts.autoIndex

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

opts.defaultExt

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.

opts.gzip

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.

opts.serverHeader

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

opts.contentType

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

opts.mimeTypes

Add new or override one or more mime-types. This affects the HTTP Content-Type header. Can either be a path to a .types file or an object hash of type(s).

ecstatic({ mimeType: { 'mime-type': ['file_extension', 'file_extension'] } })

opts.handleError

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

opts.weakEtags

Set opts.weakEtags to true in order to generate weak etags instead of strong etags. Defaults to false. See opts.weakCompare as well.

opts.weakCompare

Turn on weakCompare to allow the weak comparison function for etag validation. Defaults to false. See https://www.ietf.org/rfc/rfc2616.txt Section 13.3.3 for more details.

opts.handleOptionsMethod

Set handleOptionsMethod to true in order to respond to 'OPTIONS' calls with any standard/set headers. Defaults to false. Useful for hacking up CORS support.

opts.cors

This is a convenience setting which turns on handleOptionsMethod and sets the headers Access-Control-Allow-Origin: * and Access-Control-Allow-Headers: Authorization, Content-Type, If-Match, If-Modified-Since, If-None-Match, If-Unmodified-Since. This should be enough to quickly make cross-origin resource sharing work between development APIs. More advanced usage can come either from overriding these headers with the headers argument, or by using the handleOptionsMethod flag and then setting headers "manually." Alternately, just do it in your app using separate middlewares/abstractions.

Defaults to false.

middleware(req, res, next);

This works more or less as you'd expect.

ecstatic.showDir(folder);

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.

ecstatic command

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 also respects the PORT environment variable.

Tests:

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

$ npm test

Contribute:

Without outside contributions, ecstatic would wither and die! Before contributing, take a quick look at the contributing guidelines in ./CONTRIBUTING.md . They're relatively painless, I promise. For Windows users, it is especially important to read the ./CONTRIBUTING.md section as you can not clone ecstatic without changing some settings in git.
