sexstatic

Node-Sexstatic

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

Also adds the ability to arbitrarily modify output HTML for whatever reason. And adding additional: simple url -> string handlers simple url -> function handlers

see opts.extras if you wanna get what i'm talking about

I may or may not extend this with further addons in the future to suit my needs.

New stuff

var sexstatic = require('node-sexstatic');
var http = require('http'),
opts = require('minimist')(process.argv.slice(2)),
port = opts.port || opts.p || 8000,
dir = opts.root || opts._[0] || process.cwd();
 
// new feature #1
opts.modifyFunctions = [
  function test(c) {
    console.log('hello contents');
    return c;
  }
];
 
// new feature #2
opts.extras = {
  'service.html': '<b>oh hello</b>',
  'service.json': {
    'content-type': 'text/json',
    'content': function() {
      return { args: process.argv };
    }
  },
  'service.rpc': {
    'content-type': 'text/plain',
    content: function() {
      var well = '-- lmao';
      return function() {
        return '~* so meta '+well+'*~';
      };
    }
  }
};
 
if (opts.help || opts.h) {
  var u = console.error;
  u('usage: sexstatic [dir] {options} --port PORT');
  u('see https://npm.im/sexstatic for more docs');
  return;
}
 
http.createServer(sexstatic(dir, opts))
.listen(port, function () {
  console.log('sexstatic serving ' + dir + ' at http://0.0.0.0:' + port);
});

Examples:

express 3.0.x

var http = require('http');
var express = require('express');
var sexstatic = require('sexstatic');
 
var app = express();
app.use(sexstatic({ root: __dirname + '/public' }));
http.createServer(app).listen(8080);
 
console.log('Listening on :8080');

union

var union = require('union');
var sexstatic = require('sexstatic');
 
function inject_script(src)
{
  var index = src.indexOf("</body");
  if (index == -1) return src;
  var out = src.substr(0, index);
  out += '<script type="text/javascript" src="hello-world.js"></script>' + src.substr(index);
  return out;
}
 
union.createServer({
  before: [
    sexstatic({ root: __dirname + '/public', modifyFunctions: [ inject_script ] }),
  ]
}).listen(8080);
 
console.log('Listening on :8080');

fall through

To allow fall through to your custom routes:

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

API:

sexstatic(opts);

Pass sexstatic 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,
             modifyFunctions      : [],
             extras: {...}
           }

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.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).

opts.showDir

Turn off directory listings with opts.showDir === 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.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 sexstatic will serve ./public/some-file.js.gz in place of ./public/some-file.js when the gzipped version exists and sexstatic determines that the behavior is appropriate.

opts.handleError

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

opts.modifyFunctions

Passes an array of functions that will be performed on HTML text before it's sent to the client.

opts.extras

Passes a dictionary containing additional static, but internal files kept as strings that sexstatic will be able to serve. ex:

  ecstatic({
  root: this.root,
  cache: this.cache,
  showDir: this.showDir,
  autoIndex: this.autoIndex,
  defaultExt: this.ext,
  modifyFunctions: [
  addReloadScript
  ],
  extras: {
    'http-test.js': "file contents",
    'ws.json': {
      'content-type': 'text/json',
      'content': JSON.stringify({
        port: 8086,
        path: this.root,
        additional: "what happens in vegas, stays in vegas."
        })
      }
    }
  })

middleware(req, res, next);

This works more or less as you'd expect.

sexstatic.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 sexstatic middleware with autoindexing disabled.

sexstatic command

to start a standalone static http server, run npm install -g sexstatic and then run sexstatic [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.

Don't! Contribute back to the project that this module is forked from. This module is built for a specific use case and I'd rather not care about the parent.. Go ahead and use it for your projects though, if you'd like.
