path-observer

Watch a path of an object for changes.

Installation

Install with component(1):

$ component install ripplejs/path-observer

API

var observe = require('path-observer');

var data = {
  foo: 'bar',
  bar: [1,2,3],
  baz: {
    foo: {
      foo: 'bar'
    }
  }
};

// Wraps an object and returns a constructor for watching paths
var PathObserver = observe(data);

Now you can use this constructor to watch paths on the object for changes:

var path = new PathObserver('baz.foo.foo');

path.change(function(){
  console.log('changed');
});

path.set('baz');

You can watch for all changes to an object:

PathObserver.on('change', function(){
  // all changes
});

Changes are batched together from the previous tick.
