Observe changes to native JavaScript objects with CruddyJS. Based on the EcmaScript Harmony proposal, CruddyJS will send change updates when object values change. Here's how it works.
var observer = cruddy({ foo: 'bar' }, function (changes) {
console.log(changes);
})
observer.update(function (o) {
o.set('foo', 'boo')
})
> {
type: 'update',
name: 'foo',
object: { foo: 'boo' },
oldValue: 'bar'
}
Does your browser already support Object.observe? No problem, CruddyJS simply uses the native functionality.
NodeJS
npm install cruddy
Depending on the type of class passed to CruddyJS, you will get one of two interfaces. For basic Object classes you will receive a Model. For Array classes you will receive a Collection.
cruddy({ foo: 'bar' }, callback)
.update(function (model) {
model.set('bar', 'foo')
model.destroy('foo', 'bar')
})
cruddy([1, 3, 2], callback)
.update(function (collection) {
collection.push(0, 4, 5)
collection.shift()
collection.sort()
})
