grunt-closure-service v0.3.0

grunt-closure-service

Compile JS using the google-closure-service.

Getting Started

This plugin requires Grunt ~0.4.5

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-closure-service --save-dev

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

grunt.loadNpmTasks('grunt-closure-service');

The "closure_service" task

Overview

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

grunt.initConfig({
  closure_service: {
    options: {
      // Task-specific options go here. Available options are
      // described in the Closure Compiler API Reference.
    },
    your_target: {
      // Target-specific file lists and/or options go here.
    },
  },
});

Options

For a complete set of options, see the Google Closure Compiler API Reference.

options.compilation_level

Type: String Default value: 'SIMPLE_OPTIMIZATIONS'

The compilation level, which can be 'WHITESPACE_ONLY', 'SIMPLE_OPTIMIZATIONS', or 'ADVANCED_OPTIMIZATIONS'.

options.use_closure_library

Type: Boolean Default value: false

Whether to include the Google Closure Library while compiling.

Usage Examples

Default Options

In this example, the default options are used to do compile, which does simple optimizations on the input.

grunt.initConfig({
  closure_service: {
    options: {},
    files: {
      'dest/output.min.js': ['src/input1.js', 'src/input2.js'],
    },
  },
});

Custom Options

In this example, we specify that we only want whitespace removed, with no other optimizations.

grunt.initConfig({
  closure_service: {
    options: {
      compilation_level: 'WHITESPACE_ONLY'
    },
    files: {
      'dest/output.min.js': ['src/input1.js', 'src/input2.js'],
    },
  },
});

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.
