Best Javascript framework for RESTful HTTP networking

Question

I am more of a backend guy, but frontend development really intrigues me as I make my first steps in seeing the browser as the environment for rich and awesome applications.

What is the most suitable Javascript framework for working with a RESTful HTTP API, in other words, for retrieving (HTTP GET) and submitting (HTTP POST/PUT/DELETE) JSON representations of resources?

I am looking for a framework (if it exists!) that provides good abstraction and encapsulation of HTTP request/response, handles cross-domain and cross-browser issues.

Answer 1

Take a look at Backbone.js http://documentcloud.github.com/backbone/

Its lightweight, does not have many dependencies (only Underscore.js) and its real easy to use, yet pretty flexible and powerful.

From the site;

Backbone.js gives structure to web applications by providing models with key-value binding and custom events, collections with a rich API of enumerable functions, views with declarative event handling, and connects it all to your existing API over a RESTful JSON interface.

You can use jQuery with its .ajax() function. Example:

$.ajax({
    url: '/users',
    type: 'PUT',
    data: { name: 'John Doe', age: 30 },
    success: function ( data ) {
        alert('John Doe inserted!');
    }
});
