Package Exports

object-watch

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (object-watch) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Object._watch

Object property watching using ECMAScript 5

Object.prototype.watch is a coming feature of ECMAScript 6.

But why wait?

##How to Use

###Local Watching

var w = new Watchable({a: 1});

console.log( w.a ); // Logs: 1

w._watch('a', function(property, oldValue, newValue){
    console.log(property, oldValue, newValue);
});

w.a = 'test'; // Logs: a 1 'test' / Returns: 'test'

w._unwatch('a');

w.a = 'test2'; // Returns: 'test2'

###Remote Watching

var o = {x: 1};

var w = new Watchable();

w._watch('x', function(property, oldValue, newValue){
    console.log(property, oldValue, newValue);
}, null, o); // Note the 4th parameter

o.x = 2; // Logs: x 1 2 / Returns: 2
