Backbone.js App for JSON REST API

This library provides a client-side interface for the JSON REST API plugin for WordPress. This code in this repository generates the Backbone JavaScript application that pairs with JSON REST API. Using this library, you can interact with WordPress installations that have JSON REST API installed using Backbone Models and Collections. Learn more about Backbone here.

Usage

Setup

The compiled JavaScript is included by JSON REST API by default. Compiled code is pulled into Github Pages which is enqueued by JSON REST API. That being said, this repository is setup as a WordPress plugin for development purposes. You can activate this plugin along side JSON REST API, and they will play nice together. The Client JS will dequeue the Github Pages version of the code and enqueue it's own.

Examples

The Backbone library supplies you with some Backbone models and collections for each route in the JSON REST API. A model represents a single object such as a post. A collection represents a group of objects. We can use a model to pull a specific post from a WordPress installation:

var post = new wp.api.models.Post( { ID: 1 } );

post.fetch().done( function() {
    // post.attributes contain the attributes of the post
    console.log( post.attributes );
});

We can also grab a collection of posts:

var posts = new wp.api.collections.Posts();

posts.fetch().done( function() {
    posts.each( function( post ) {
        // post.attributes contain the attributes of the post
        console.log( post.attributes );
    });
});

Requests are broken up into pages based on how posts_per_page is set or filtered. Therefore, sometimes we need to paginate through a collection:

var posts = new wp.api.collections.Posts();

posts.fetch().done( function() {
    posts.each( function( post ) {
        // post.attributes contain the attributes of the post
        console.log( post.attributes );
    });

    if ( posts.hasMore() ) {
        posts.more().done( function() {
            posts.each( function( post ) {
                // post.attributes contain the attributes of the post
                console.log( post.attributes );
            });
        });
    }
});

Development

To develop, build and test this library, you must have Node installed. For Windows users, simply download and install Node. For Mac users, we recommend installing Node using Homebrew. Once Homebrew is installed, run brew install node to install Node.js.

Installation

Clone this repository, and then execute the following commands within the checkout directory:

$ npm install

This will use Node's NPM package manager to install all the dependencies for building and testing this library. We use Bower to manage client script dependencies, but Bower script installation is handled as part of the npm install command.

Building

To update the compiled JavaScript files in the build/ directory after you've made changes, run the library's build script with the npm command:

$ npm run build

This will use Grunt to check the source scripts in js/ for syntax errors, then concatenate and minify them to create the minified wp-api.min.js file and a corresponding source map file.

Testing

You can run the QUnit tests for this library using Grunt:

$ npm test

A note on Grunt

The custom "build" and "test" scripts defined in this library's package.json enable access to Grunt's functionality after a simple npm install; however, these commands can also be run directly using Grunt itself. In order to gain access to the grunt console command, you must globally install the Grunt command-line interface:

$ npm install -g grunt-cli

Once grunt-cli has been installed, you can run the build and test commands with grunt and grunt test, respectively, without having to invoke the scripts via NPM.
