About

Autoloads JS files based on name when the class is needed.

This module removes the needs of using require() all over your files. Simply define the autoloader to your codebase, and use the names relative to the files.

ie lib/Foo/Bar/Baz.js when you load 'lib/' makes Foo_Bar_Baz require('./lib/Foo/Bar/Baz.js') automatically and return the value.

2.0 Requirements

2.0 Drastically changes how this project works. It now requires --harmony under Node 0.10, and the usage scenarios have completely changed. It now will replace underscores as seperators such as Foo_Bar instead of Foo.Bar.

It also does not have to do any directory scanning and setting up tons of getters, simple Proxy on global catches unreferenced variables!

Install

Install with npm install autoloader

Usage

Run node with --harmony

Folder structure:

/lib/
    Foo/
        Bar.js
    Foo.js
test.js
package.json (main: 'test.js')

File contents:

lib/Foo.js:

module.export = function() {
    console.log("Foo")
    Foo_Bar();
};

lib/Foo/Bar.js:

module.export = function() {
    console.log("Foo_Bar")
};

test.js:

require('autoloader')(__dirname + '/lib')
Foo();

Loading the module would print to screen:

Foo
Foo_Bar

You may optionally pass an object as the 2nd parameter and the autoloader will bind to that object instead of global. So consider:

global.App = require('autoloader')(__dirname + '/lib', require('./myapp'));
new App.Foo_Bar();

Custom Loaders

If you pass a function as the 1st argument, autoloader will execute that instead of loading by directory, allowing you to control what is returned. Callback signature

function (name, object) { }

You will need to assign the value yourself if you wish to not have your loader fire every access.
