#load-grunt-config

load-grunt-config is a Grunt library that allows you to break up your Gruntfile config by task. For most small projects a single Gruntfile.js is perfect. But as a project grows, the Gruntfile.js can quickly become unmanagable; this is where load-grunt-config comes in handy. It was heavily inspired by Thomas Boyt's "More Maintainable Gruntfiles".

##Features

• Each task has its own config file. Example: jshint.js, mocha.js, etc.
• Auto load all grunt plugins. Uses load-grunt-tasks.
• Auto expose package.json (<%= package.name %>).
• Support for YAML files.
• Support for coffeescript files.
• Support for returning a function.
• Easily register task aliases with aliases.(js|yaml|coffee).
• Config overrides
• Config grouping

##Installation

npm install -D load-grunt-config

##Example

Basic Gruntfile.js

module.exports = function(grunt) {

	require('load-grunt-config')(grunt);

};

Gruntfile.js with options

module.exports = function(grunt) {

	require('load-grunt-config')(grunt, {
		configPath: path.join(process.cwd(), 'grunt'), //path to task.js files, defaults to grunt dir
		init: true, //auto grunt.initConfig
		data: { //data passed into config.  Can use with <%= test %>
			test: false
		},
		loadGruntTasks: { //can optionally pass options to load-grunt-tasks.  If you set to false, it will disable auto loading tasks.
			pattern: 'grunt-*',
			config: require('./package.json'),
			scope: 'devDependencies'
		}
	});

};

###Grunt tasks files

Here's what the files in your grunt/ folder could look like. You can use either .js, .yaml, or .coffee - whatever you prefer and you can mix and match as you see fit.

Example js file returning an object - grunt/watch.js

module.exports = {
  all: {
    files: [
      '<%= jshint.all %>',
      'grunt/*.yaml'
    ],
    tasks: [
      'default'
    ]
  }
};

Example js file returning a function - grunt/jshint.js

module.exports = function (grunt, options) {
  return {
    all: [
      'Gruntfile.js',
      'grunt/*.js',
      'lib/*.js',
      'test/*.js',
      options.someFile
    ]
  };
};

Example yaml file - grunt/notify.yaml

default:
  options:
    message: 'Default finished'

Example coffee file - grunt/task.coffee

module.exports =
  options:
    bare: true

###Aliases

If your grunt/ folder contains an aliases.(js|yaml|coffee) file, load-grunt-config will use that to define your tasks aliases (like grunt.registerTask('default', ['jshint']);).

grunt/aliases.yaml

default:
  - 'jshint'
  - 'mocha'
  - 'notify'

Custom Config

There are certain scenarios where you might have a base config for your team, and you want to be able to override some of the config based on your personal setup. You can do that with the overridePath property. In this case, the library will merge the two, with the override path taking priority. For example:

module.exports = function(grunt) {

  require('load-grunt-config')(grunt, {
    configPath: path.join(process.cwd(), 'vendor'),
    overridePath: path.join(process.cwd(), 'config-'+process.env.USER)
  });

};

Config Grouping

load-grunt-config also supports grouping tasks. This is handy when you want to group all of your script or css tasks together. To do that, just add the suffix -tasks to your config filename and load-grunt-config will treat the filename as the task target and the top level keys as the task names.

Here's an example

Filename: /config/scripts-tasks.yaml

jshint:
  files:
    - '*.js'
watch:
  files:
    - '*.js'
  tasks:
    - 'scripts'

This would be the equivalent in your Gruntfile.js:

{
  jshint: {
    scripts: {
      files: [
        '*.js'
      ]
    }
  },
  watch: {
    scripts: {
      files: [
        '*.js'
      ],
      tasks: [
        'scripts'
      ]
    }
  }
}
