Build Status Code Climate NPM Gitter Chat

BetaJS is a general-purpose JavaScript helper module. It contains a variety of helper functions and classes.

Getting Started

You can use the library in the browser, in your NodeJS project and compile it as well.

Browser

	<script src="betajs/dist/betajs.min.js"></script>

NodeJS

	var BetaJS = require('betajs/dist/beta.js');

Compile

	git clone https://github.com/betajs/betajs.git
	npm install
	grunt

Basic Usage

The BetaJS module contains a variety of low-level helper libraries, particularly:

  • Asynchronous behaviour and Promises
  • Object Orientation
  • Event Handling
  • Dynamic Lists and Collections
  • Dynamic Properties
  • Remote Method Invocation
  • String Manipulation and Templating
  • Binary Search Trees
  • Timers and Time
  • Iterators
  • Uris
  • State Machine and Abstract Routing

Properties

	var properties = new BetaJS.Properties.Properties({foobar: "initial value"});

	properties.set("foobar", "second value");

	var value = properties.get("foobar");
	// value === "second value"
	
	properties.of('change:foobar', function(newValue, oldValue) {
		console.log('The value of foobar has been changed from', oldValue, 'to', newValue);
	});

Object Orientation

  TestClass = BetaJS.Class.extend(null, {
  
    y: 0,
  
    fooBar: function (x) {
      console.log("Test Class Instance", "fooBar", x, y);
    }
    
  }, {
  
    staticFooBar: function (x) {
      console.log("Test Class", "staticFooBar", x);
    }
    
  });
  TestClass.staticFooBar(5);
  var first = new TestClass();
  first.y = 1;
  first.foobar(2);
  var second = new TestClass();
  second.y = 3;
  second.foobar(4);
  Test Class  staticFooBar  5
  Test Class Instance  fooBar  2  1
  Test Class Instance  fooBar  4  3

Events

	var events = new BetaJS.Events.Events();

	events.trigger("event_name", event_data1, event_data2);

	events.on("event_name", function (event_arg1, event_arg2) {
		// Do something
	}, function_context);

	events.off("event_name", null, function_context);
