grunt-bower-main

Adds only the main files from Bower components to source code. Integrates seamlessly with grunt-wiredep.

Getting Started

This plugin requires Grunt.

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, you may install this plugin with this command:

npm install grunt-bower-main --save-dev

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

grunt.loadNpmTasks('grunt-bower-main');

The "bower_main" task

Overview

In your project's Gruntfile, add a section named bower_main to the data object passed into grunt.initConfig().

grunt.initConfig({
  bower_main: {
    copy: {
      options: {
        dest: 'src/resources/bower_components'
      }
    }
  }
})

Options

options.method

Type: String Default value: 'copy'

Dictates whether the main files will be copied to a destination directory ('copy'), or if other files will be removed from the bower_components directory ('prune').

The default location for the bower_components directory is the top level directory. Setting method to 'copy' will allow you to keep the bower_components directory and copy the main files into your source code. This is useful if you are not using a static frontend stack (like a Java webapp for example). If you don't care about keeping the original component files then you can set your bower_components directory to live directly in the source code and prune away unnecessary files. This method keeps the 'bower.json' and '.bower.json' files also so that bower install does not reinstall them every time.

options.dest

Type: String Default value: null

This must be set if using method: 'copy', will be the top-level destination directory of the main files.

options.tmpDir

Type: String Default value: '.tmp'

This is used with method: 'prune'. The plugin copies main files here, deletes the bower_components directory, and renames this directory to 'bower_components' (or whatever the original bower components directory was named.) Change this if you are using '.tmp' for any other plugin.

options.bowerrc

Type: String Default value: '.bowerrc'

Points to your .bowerrc file if you have one.

options.overrides

Type: Object Default value: undefined

Specify main file overrides. This can also be set in your project's bower.json in the same format, but options take precedent:

overrides: {
    fontawesome: {
        main: './css/font-awesome.css' //exclude fonts
    },
    bootstrap: {
        main: ['dist/js/bootstrap.js'] //exclude styles
    }
}

Usage Examples

This task is generally used in tandem with grunt-wiredep. Run this task first, and then configure wiredep as you normally would. This is possible because the directory structure of the output of this task is identical to the original. The motivation to create this task comes from working in a Java house and we wanted to pull the bower_components out of the artifact, but still be able to use wiredep.

Copy

To get started quickly, just set a 'dest' directory:

grunt.initConfig({
  bower_main: {
    copy: {
      options: {
        dest: 'src/resources/bower_components'
      }
    }  
  }
})

Prune

If you want to prune instead, just tell it to prune and change the temp directory if necessary:

grunt.initConfig({
  bower_main: {
    prune: {
      options: {
        method: 'prune',
        tmpDir: 'pruneTmp'
      }
    }  
  }
})

Contributing

In lieu of a formal styleguide, take care to maintain the existing coding style. Add unit tests for any new or changed functionality. Lint and test your code using Grunt.
