Broccoli

A fast, reliable asset pipeline, supporting constant-time rebuilds and compact build definitions. Comparable to the Rails asset pipeline in scope, though it runs on Node and is backend-agnostic. For background and architecture, see the introductory blog post.

For the command line interface, see broccoli-cli.

Installation

npm install --save-dev broccoli
npm install --global broccoli-cli

Brocfile.js

A Brocfile.js file in the project root contains the build specification. It should export a tree.

A tree can be any string representing a directory path, like 'app' or 'src'. Or a tree can be an object conforming to the Plugin API Specification. A Brocfile.js will usually directly work with only directory paths, and then use the plugins in the Plugins section to generate transformed trees.

The following simple Brocfile.js would export the app/ subdirectory as a tree:

module.exports = 'app'

With that Brocfile, the build result would equal the contents of the app tree in your project folder. For example, say your project contains these files:

app
├─ main.js
└─ helper.js
Brocfile.js
package.json
…

Running broccoli build the-output (a command provided by broccoli-cli) would generate the following folder within your project folder:

the-output
├─ main.js
└─ helper.js

Using plugins in a Brocfile.js

The following Brocfile.js exports the app/ subdirectory as appkit/:

var Funnel = require('broccoli-funnel')

module.exports = new Funnel('app', {
  destDir: 'appkit'
})

That example uses the plugin broccoli-funnel. In order for the require call to work, you must first put the plugin in your devDependencies and install it, with

npm install --save-dev broccoli-funnel

With the above Brocfile.js and the file tree from the previous example, running broccoli build the-output would generate the following folder:

the-output
└─ appkit
   ├─ main.js
   └─ helper.js

Plugins

You can find plugins under the broccoli-plugin keyword on npm.

Running Broccoli, Directly or Through Other Tools

Also see docs/broccoli-1-0-plugin-api.md on how to upgrade from Broccoli 0.x to the Broccoli 1.x API.

Security

• Do not run broccoli serve on a production server. While this is theoretically safe, it exposes a needlessly large amount of attack surface just for serving static assets. Instead, use broccoli build to precompile your assets, and serve the static files from a web server of your choice.
