grunt-requiregrep v0.1.0

Grunt RequireDep Task

Searchs for dependencies required on your source code (eg. template files) and generates an AMD module from it.

Example:

<!-- a/path/to/page.html -->
<!-- require("jquery, widgets, twitter") -->

<!-- another/path/to/anotherpage.html -->
<!-- require("jquery, widgets, fx") -->

Running grunt requiredep can generate:

// all.js
define(['jquery', 'widgets', 'twitter', 'fx'], function()){
	console.log('all modules loaded');
});

Now you can include this new module in your requirejs main config file. This allows you to use a AMD bundler like r.js (check grunt-contrib-requirejs).

Installation

Install this grunt plugin next to your project's grunt.js gruntfile with: npm install grunt-contrib-requiregrep

Then add this line to your project's gruntfile:

grunt.loadNpmTasks('grunt-requiregrep');

Documentation

Supports the following options:

• files: source files to grep for AMD dependencies (eg. *.html).
• dest: output filename (eg all.js)
• options:
  • requirePattern: regex to detect dependencies on source files, first capture group should be a comma-separated list of module names. default: /require\(\s*[\'\"]([^\'\"]*)[\'\"]/gi
  • moduleName: output module name. default: null, ie. anonymous module
  • onLoad: code to include on module load (eg. console.log('all modules loaded!');). default: ''
  • forEachFile: function that will be called for each parsed file with these arguments: file, contents, registerDependency (use this function add a dependency)

Example Usage

/*jslint node:true*/

module.exports = function (grunt) {

	'use strict';

	grunt.loadNpmTasks('grunt-requiregrep'); // load the task

	grunt.initConfig({
		watch: {
			files: '<config:requiregrep.files>',
			tasks: 'requiregrep'
		},

		requiregrep: { // configure the task
			all: {
				files: [ // some example files
					'home.html',
					'view/**/*.html'
				],
				dest: 'scripts/all.js',
				options: {
					onLoad: 'if (window.console){window.console('all modules loaded');}', // run after all dependencies are loaded
				}
			}
		}
	});

	grunt.registerTask('default', 'watch');
};
