smartload-grunt-tasks

Load multiple grunt tasks dynamically using globbing patterns. Load only the tasks you need based on the current task being run.

Usually you would have to load each task one by one, which is unnecessarily cumbersome. And despite only running a single build task, Grunt loads every single task which can add a second or more if it's a big project. Tell it to only load the one(s) you need based on what is being run.

This module will read the dependencies/devDependencies/peerDependencies in your package.json and load grunt tasks that match the provided patterns.

Before

Load everything you might possibly need in your Gruntfile.js

grunt customtask:dev

require(__dirname + '/grunt/tasks/customTask.js');
require(__dirname + '/grunt/tasks/customTask2.js');
require(__dirname + '/grunt/tasks/customTask3.js');
grunt.loadNpmTasks('grunt-shell');
grunt.loadNpmTasks('grunt-sass');
grunt.loadNpmTasks('grunt-recess');
grunt.loadNpmTasks('grunt-newer');
grunt.loadNpmTasks('grunt-contrib-imagemin');
grunt.loadNpmTasks('grunt-styl');

After

Let smartload-grunt-tasks load only what you need!

grunt customtask:dev

require('smartload-grunt-tasks')(grunt, {
	dir: 'grunt/tasks/',
	smartLoad: {
		'customtask:dev': ['customtask']
		'autoprefixer:sass': ['grunt-autoprefixer'],
		'newer:imagemin:assets_dev': ['grunt-newer', 'grunt-contrib-imagemin'],
	}
});

Install

$ npm install --save-dev smartload-grunt-tasks

Example config

// Gruntfile.js
module.exports = function (grunt) {
	// load all grunt tasks matching the `grunt-*` pattern
	require('smartload-grunt-tasks')(grunt, {

		// in which directory (if any) do you have custom tasks?
		// Each .js file will be require'd
		dir: 'grunt/tasks/',

		// which tasks should be loaded for each CLI task argument?
		smartLoad: {
			'customtask:dev': ['grunt-styl', 'customtask'],
			'autoprefixer:sass': ['grunt-autoprefixer'],
			'newer:imagemin:assets_dev': ['grunt-newer', 'grunt-contrib-imagemin']
		}
	});

	grunt.initConfig({});
	grunt.registerTask('default', []);
}

Usage examples

Load all grunt tasks

require('smartload-grunt-tasks')(grunt);

Equivalent to:

require('smartload-grunt-tasks')(grunt, {pkgPattern: 'grunt-*'});

Load all grunt-contrib tasks

require('smartload-grunt-tasks')(grunt, {pkgPattern: 'grunt-contrib-*'});

Load all grunt-contrib tasks, another non-contrib task, and every .js file in the grunt_tasks directory:

require('smartload-grunt-tasks')(grunt, {
	pkgPattern: ['grunt-contrib-*', 'grunt-shell'],
	dir: 'grunt_tasks'
});

Load all grunt-contrib tasks excluding one

You can exclude tasks using the negate ! globbing pattern:

require('smartload-grunt-tasks')(grunt, {pkgPattern: ['grunt-contrib-*', '!grunt-contrib-coffee']});

Set custom path to package.json

require('smartload-grunt-tasks')(grunt, {pkgConfig: '../package'});

Only load from devDependencies and when running the grunt task, only load grunt-contrib-sass task:

require('smartload-grunt-tasks')(grunt, {
	pkgScope: 'devDependencies',
	smartLoad: {
		'sass': ['grunt-contrib-sass']
	}
});

Only load from devDependencies and dependencies

require('smartload-grunt-tasks')(grunt, {pkgScope: ['devDependencies', 'dependencies']});

All options in use

require('smartload-grunt-tasks')(grunt, {
	pkgPattern: 'grunt-contrib-*',
	pkgConfig: '../package.json',
	pkgScope: 'devDependencies',
	dir: 'mycustomtasks/',
	dirPattern: '**/*.js',
	smartLoad: {
		'taskFromCLI': ['grunt-whatever']
	}
});

Options

Note: Since this was shamelessly stolen from and built upon load-grunt-tasks, it's backwards compatible; load-grunt-tasks' option keys will work here, too.

pkgPattern

Type: String, Array
Default: 'grunt-*' (globbing pattern)

pkgConfig

Type: String, Object
Default: Path to nearest package.json

pkgScope

Type: String, Array
Default: ['dependencies', 'devDependencies', 'peerDependencies']

dir

Type: String
Default: false (don't load any custom tasks)

dirPattern

Type: String
Default: '**/*.js

smartLoad

Type: Object
Default: false (load everything every time)
