Express Combo

Combo handler for express applications.

Goals

• register and serve static assets from a specific folder
• register and serve static assets based on an explicit mapping to protect other files that should not be exposed
• serve combo urls based on the static assets that were registered

Installation

Install using npm:

$ npm install express-combo

Usage

var express = require('express'),
    app = express(),
    statichandler = require('express-combo');

app.get('/static', statichandler.folder('public', 'full/path/to/folder/'));

app.get('/static', statichandler.map('protected', {
    'something/foo.js": "full/path/to/something/foo.js',
    'bar.js": "full/path/to/something/bar.js'
}));

app.get('/static', statichandler.combine({
    comboBase: '/combo~',
    comboSep: '~'
}));

The example above will allow you to access any file within the folder full/path/to/folder/ by following the route:

• http://hostname:port/static/public/any/file.js

In this case, serving files without any protection, which means all files could be accessed. Under the hood this is equivalent to use express.static middleware. It also expose two files, but this time adding some explicit mapping for them, exposing:

• http://hostname:port/static/protected/something/foo.js
• http://hostname:port/static/protected/bar.js

It protects any other file within the those folders. It also provides a nice abstraction where filenames and paths in the filesystem are not longer relevant when it comes to serve them, and the mapping has to be explicit.

And last, but not least, it turns on the combo capabilities for all the previous registered assets, and doing so by defining the separator token. As a result, a urls like these will be valid:

• http://hostname:port/static/combo~something/foo.js~bar.js
• http://hostname:port/static/combo~any/file.js~something/foo.js~bar.js

Note: the /static prefix is optional, and you can remove it all together, and even use app.use() directly for those middleware.

TODO

• support custom filters (regex) to include and/or exclude assets thru folder and map.
• css relative path correction when serving thru combo
