Blend

Merge, analyze, and optimize client-side assets for web applications and static web sites.

Example

Given the following directory structure:

project
  lib
    jquery-1.7.2.min.js
  src
    app.js
    components
      menu.js
    common
      helpers.js

And the following app.js:

/* app.js */

//= require jquery
//= require menu
var app = {};

And the following menu.js:

/* menu.js */

//= require jquery
//= require helpers
var menu = {};

And the following helpers.js:

/* helpers.js */

var helpers = {};

Running blend with no arguments from the project directory will produce this directory structure:

project
  lib
    jquery-1.7.2.min.js
  output
    app.js
    app.min.js
    menu.js
    menu.min.js
  src
    app.js
    components
      menu.js
    common
      helpers.js

Where app.js has the following content:

/* app.js */

/* ... the minified JQuery code, included only once */
var helpers = {};
var menu = {}
var app = {};
