Iota Observable has been designed to play nicely with Rivets, a little template engine with declarative data binding from Michael Richards. Both libraries strive to "do one thing and do it well". They leave everything else to your choice — a modular approach. You might want to give the Rivets & Iota Observable combo a chance if you feel that AngularJS, EmberJS, Knockout, Batman etc. are too invasive and big for your use case.
# Extend from Observable class Person extends Observable constructor: (@firstName, @lastName) -> super() name: -> @get('firstName') + ' ' + @get('lastName') # Create a person obj = new Person 'Bela', 'Bartók' # Query initial value of name (normally done by view) console.log 'Initial name: ' + obj.get('name') # Register observer obj.on 'name', -> console.log("Name has changed") # Change property value, prints "Name has changed" obj.set 'firstName', 'Béla'
With Rivets (CoffeeScript)
# Create counter object and make it Observable model = counter: value: 5 Observable.makeObservable model.counter # Bind counter value to a DOM element template = '<div data-text="counter.value" />' domElement = $(template) rivets.bind(domElement, model) # Append DOM element to main tree $(domElement).appendTo "body"
