In-Depth Information
This simple example illustrates how to retrieve and save data with Angular's default
CRUD methods ( .get , .save , .delete , and .query ):
// Define CreditCard class
var CreditCard = $resource ( '/user/:userId/card/:cardId' ,
{ userId : 123 , cardId : '@id' }, {
charge : { method : 'POST' , params : { charge : true }}
});
// We can retrieve a collection from the server
var cards = CreditCard . query ();
// GET: /user/123/card
// server returns: [ {id:456, number:'1234', name:'Smith'} ];
var card = cards [ 0 ];
// each item is an instance of CreditCard
expect ( card instanceof CreditCard ). toEqual ( true );
card . name = "J. Smith" ;
// non GET methods are mapped onto the instances
card . $save ();
// POST: /user/123/card/456 {id:456, number:'1234', name:'J. Smith'}
// server returns: {id:456, number:'1234', name: 'J. Smith'};

Batman
Created by Shopify, Batman.js is another framework similar to Knockout and Angular.
It has a nice UI binding system based on HTML attributes and is the only framework
written in coffeescript. Batman.js is also tightly integrated with Node.js and even goes
to the extent of having its own (optional) Node.js server. At this time, its following is still
relatively small on github in comparison to the others ( Figure 4-14 ).

nization, see the HTML5e Batman repository .
