Automagically wire-up installed Bower components into your RequireJS config, with the ability to alias and prefix module IDs.

Getting Started

If you haven't used grunt before, be sure to check out the Getting Started guide, as it explains how to create a gruntfile as well as install and use grunt plugins. Once you're familiar with that process, install this plugin with this command:

npm install grunt-bower-requirejs-alias --save-dev

Once the plugin has been installed, it may be enabled inside your Gruntfile with this line of JavaScript:


Example usage

    bower: {
        target: {
            rjsConfig: 'app/config.js'
grunt.registerTask('default', ['bower']);


When the bower task is run it merges the paths of installed Bower components into the paths property of your RequireJS config.

You trigger this task from another task in your Gruntfile or through the CLI: grunt bower


Required Type: String

Specify a relative path to your RequireJS config.

Make sure to specify the baseUrl property in your RequireJS config if you want to use relative paths.



Default: [] Type: Array

Specify components to be excluded from being added to the RequireJS config.


Default: null Type: String

Generate paths relative to a specific directory. This option is for anyone not using data-main who wishes to set their own base.


Prefix all bower module ids with a specific string

Default: undefined Type: String


Alias one module name to another. Applied before prefix.

Default: {} Type: Object

Things to remember

Config file

You need to already have a config.js file at the location specified by rjsConfig. At a minimum, the file should look like this:

    baseUrl: './',
    paths: {}

You still need to create a path for your js files. The grunt task will only create paths for third party libraries specified in bower.json.

    baseUrl: './',
    paths: {
        myComponent: 'js/myComponent.js'

The task does not overwrite the config file, it just adds additional paths to it. So paths you add will be preserved. Keep in mind that if you change or remove one of your bower dependencies after you've run the task, that path will still exist in the config file and you'll need to manually remove it.

RequireJS component

Although RequireJS does not provide a bower.json file, a path to require.js will still be created in your rjsConfig file. The path's name will be requirejs. If you are optimizing your scripts with r.js you can use this path to make sure RequireJS is included in your bundle.
