grunt-closure-wrap

Provide a simple way to wrap existing javascript file into a simple closure with provided interface.

Note, use this plugin to quickly port an existing large project to be inside a closure. It is not recommended to use this style as the main development since the interface file is not together with the other source files. Although with the modern IDE, it's not really a problem...

Getting Started

This plugin requires Grunt ~0.4.1

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-wrap --save-dev

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

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

The "closure_wrap" task

Overview

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

grunt.initConfig({
  closure_wrap: {
    options: {
      src: 'js-file-i-want-to-wrap-inside-a-closure',
      interface: '{ publicMethod1: function(){}, publicMethod2: function(){} }', //this can be a filename that contains the object as well.
      dest: 'my-final-file.js',
      header: 'var MyLibrary = function(){', //start the closure, define the closure-scoped variables here if needed.
      footer: '}();' //close the closure
    },
    your_target: {
      // Target-specific file lists and/or options go here.
    },
  },
})

Usage Examples

Default Options

In this example, the default options are used to do something with whatever. So if the testing file has the content Testing and the 123 file had the content 1 2 3, the generated result would be Testing, 1 2 3.

grunt.initConfig({
  closure_wrap: {
    options: {},
    files: {
      'dest/default_options': ['src/testing', 'src/123'],
    },
  },
})

Custom Options

In this example, custom options are used to do something else with whatever else. So if the testing file has the content Testing and the 123 file had the content 1 2 3, the generated result in this case would be Testing: 1 2 3 !!!

grunt.initConfig({
  closure_wrap: {
    options: {
      separator: ': ',
      punctuation: ' !!!',
    },
    files: {
      'dest/default_options': ['src/testing', 'src/123'],
    },
  },
})
