Yasl

Yasl is a simple JavaScript compiler for managing dependencies between JavaScript files. N.B.: This module is very similar to browserify (http://browserify.org/) which is way more mature. You can install yasl with npm install yasl -g. Usage:

yasl /path/to/root yasl.relative.path.to.main > /path/to/output.js

Each file compiled by yasl is embeded within an anonymous function to provide encapsulation. The return value of each file is accessible by other files using the keyword yasl. Below is a typical configuration of a JavaScript file compilable by yasl:

var module_name = yasl.relative.path.to.file
var exports = {}
// populate the exports object
return exports; 

An example of project compiled with the command yasl ./counter yasl.button > ./counter/main.js can be found at https://github.com/lachrist/yasl/tree/master/counter.
