trackchange

Transparent change-tracking using Harmony Proxies.

Build Status

Usage

Add trackchange to your project:

Installation (Node.JS)

npm install --save trackchange

Reference it in your code:

var ChangeTracker = require('trackchange');

Running

Be sure to run node with the --harmony flag.

node --harmony myscript.js

Using in code

var orig = {
  test: 123
};
 
// Create a wrapper that tracks changes.
var obj = ChangeTracker.create(orig);
 
// No changes initially:
console.log(obj.__dirty); // -> []
 
// Do things
orig.test = 1;
orig.other = true;
 
// Magical change tracking!
console.log(obj.__dirty); // -> ['test', 'other']

You can even wrap constructors. This ensures that each created instance automatically has change tracking built-in:

var TestType = ChangeTracker.createWrapper(OrigType);
 
var obj = new TestType();
console.log(obj.__dirty);
