Grunt task that creates AMD modules by searching for dependencies on source files

Grunt Require-Grep Task

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


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

Running grunt-requiregrep can generate:

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 way if you use a bundler like r.js (check grunt-contrib-requirejs) it will include all modules used on your source files automatically.


Install this grunt plugin with: npm install grunt-requiregrep

Then add this line to your grunt.js gruntfile:



Supports the following options:

  • src/files: source files to grep for AMD dependencies (default: **/*.*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!');).
    • forEachFile: function that will be called for each parsed file with these arguments: file, contents, registerDependency (use this function add a dependency programmatically)

Example Usage

/*jslint node:true*/
module.exports = function (grunt) {
    'use strict';
    grunt.loadNpmTasks('grunt-requiregrep'); // load the task 
        watch: {
            files: '<config:requiregrep.files>',
            tasks: 'requiregrep'
        requiregrep: { // configure the task 
            all: {
                files: {
                    'scripts/all.js': [
                options: {
                    onLoad: 'if (window.console){window.console('all modules loaded');}', // run after all dependencies are loaded 
    grunt.registerTask('default', 'watch');
