grunt-js2coffee

Convert JavaScript to CoffeeScript, with Grunt.js

Getting Started

If you haven't used grunt before, be sure to check out the Getting Started guide.

From the same directory as your project's Gruntfile and package.json, install this plugin with the following command:

npm install js2coffee --save-dev

Once that's done, add this line to your project's Gruntfile:

grunt.loadNpmTasks('js2coffee');

If the plugin has been installed correctly, running grunt --help at the command line should list the newly-installed plugin's task or tasks. In addition, the plugin should be listed in package.json as a devDependency, which ensures that it will be installed whenever the npm install command is run.

The "js2coffee" task

no_comments

Usage examples

In your project's Gruntfile, add a section named js2coffee to the data object passed into grunt.initConfig().

grunt.initConfig({

  js2coffee: {
    options: {
      // Task-level options go here
    },
    // Example: this target compiles a single file from JavaScript to CofeeScript
    single: {
      src: 'tmp/mout/src/string/contains.js',
      dest: 'tmp/single/contains.coffee'
    },
    // Example: this target compiles a directory of JavaScript files to
    // individual CofeeScript files, retaining the same directory structure
    // in the destination folder
    each: {
      options: {},
      files: [
        {
          expand: true,
          cwd: 'tmp/mout/src',
          src: ['**/*.js'],
          dest: 'tmp/coffee/',
          ext: '.coffee'
        }
      ]
    }
  }

});

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.
