grunt-contrib-coffee

Compile CoffeeScript files to JavaScript.

Getting Started

This plugin requires Grunt ~0.4.0

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-contrib-coffee --save-dev

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

grunt.loadNpmTasks('grunt-contrib-coffee');

This plugin was designed to work with Grunt 0.4.x. If you're still using grunt v0.3.x it's strongly recommended that you upgrade, but in case you can't please use v0.3.2.

Coffee task

Run this task with the grunt coffee command.

Task targets, files and options may be specified according to the grunt Configuring tasks guide.

Options

separator

Type: String Default: linefeed

Concatenated files will be joined on this string.

bare

Type: boolean

Compile the JavaScript without the top-level function safety wrapper.

join

Type: boolean Default: false

When compiling multiple .coffee files into a single .js file, concatenate first.

sourceMap

Type: boolean Default: false

Compile JavaScript and create a .map file linking it to the CoffeeScript source. When compiling multiple .coffee files to a single .js file, concatenation occurs as though the 'join' option is enabled. The concatenated CoffeeScript is written into the output directory, and becomes the target for source mapping.

Usage Examples

coffee: {
  compile: {
    files: {
      'path/to/result.js': 'path/to/source.coffee', // 1:1 compile
      'path/to/another.js': ['path/to/sources/*.coffee', 'path/to/more/*.coffee'] // compile and concat into single file
    }
  },

  compileBare: {
    options: {
      bare: true
    },
    files: {
      'path/to/result.js': 'path/to/source.coffee', // 1:1 compile
      'path/to/another.js': ['path/to/sources/*.coffee', 'path/to/more/*.coffee'] // compile and concat into single file
    }
  },

  compileJoined: {
    options: {
      join: true
    },
    files: {
      'path/to/result.js': 'path/to/source.coffee', // 1:1 compile, identical output to join = false
      'path/to/another.js': ['path/to/sources/*.coffee', 'path/to/more/*.coffee'] // concat then compile into single file
    }
  },

  compileWithMaps: {
    options: {
      sourceMap: true
    },
    files: {
      'path/to/result.js': 'path/to/source.coffee', // 1:1 compile
      'path/to/another.js': ['path/to/sources/*.coffee', 'path/to/more/*.coffee'] // concat then compile into single file
    }
  },

  glob_to_multiple: {
    expand: true,
    flatten: true,
    cwd: 'path/to',
    src: ['*.coffee'],
    dest: 'path/to/dest/',
    ext: '.js'
  }
}

For more examples on how to use the expand API to manipulate the default dynamic path construction in the glob_to_multiple examples, see "Building the files object dynamically" in the grunt wiki entry Configuring Tasks.
