Split a grunt configuration into multiple files

Grunt: Config Directory

Split a grunt configuration into multiple files

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-config-dir --save-dev

Somewhere in your project's Gruntfile, initialize grunt-config-dir like this:

require('grunt-config-dir')(grunt, {
    configDir: require('path').resolve('grunt'),
    fileExtensions: ['js', 'coffee']
}, function(err){ grunt.log.error(err) });

Then create your configDir and move as many properties as you wish from grunt.config into files beneath it. Filenames with truncated extensions are used as the property keys. Your property files should export a function expecting the grunt object as a parameter, which returns the property value.

Type: String Default value: path.resolve('grunt')

A directory relative to the Gruntfile to contain your grunt.config property files.

Type: Array Default value: ['js', 'coffee']

Valid file extensions to import properties from within configDir.

  // copy config has been moved to `grunt/copy.js` 
  copy: {
    main: {
      files: [
        { expand: true, src: ['path/*'], dest: 'dest/', filter: 'isFile' }
// grunt.loadNpmTasks('grunt-contrib-copy'); 
module.exports = function(grunt) {
  return {
    main: {
      files: [
        { expand: true, src: ['path/*'], dest: 'dest/', filter: 'isFile' }
