A Class implementation inspired by Backbone classes
NobleClass is a simple Class implementation inspired by Backbone, but using ES5 features. This means it copies property values such as enumerability and writability across classes. It also has proper prototypal inheritence.
It also comes with a complete EventEmitter implementation, similar to
Backbone's, but also borrowing some bits from Node's EventEmitter. It features
It is more comprehensive than a simple
util.inherits() in Node, as it allows
you to cleanly express additional prototype & static properties, and also
inherits static properties from the parent class. The built in EventEmitter is
also useful as it offers additional benefits to EventEmitter (explianed later)
and works in the browser.
I suppose some of you are asking "Why? There are plenty of decent Class implementations around, even some ES5 ones, even ones with EventEmitters etc". This is true, mostly. But none do it how I wanted to do it. Don't like how I've done it? That's fine, use another, or write your own, or fork mine!
Making new classes is easy.
constructor in the prototype will automatically
be fired upon class construction.
var Class = ;AThing = Class;AnotherThing = AThing;console; // trueconsole; // trueconsole; // true
Each class comes with the
emit methods, which can be
used like so:
var Class = ;AnotherThing = Class;inst = ;inst;inst; // Fires on all events.inst // Fires when the 'change:name' event is `off'ed`inst // Fires the `off:change:name` event and removes all `change:name` events
