(auto)mate
If you aren't using productivity tools or task automation, you are working too hard.
Grunt… Gulp!
Grunt or Gulp
● Based on files
● Configuration over code
● 4300+ plugins
● Task runner
● Based on streams
● Code over configuration
● Build system
● 1200+ plugins
Grunt or Gulp

npm
Grunt project
package.jsonused by npm to store metadata for projects published as npm modules
Gruntfile.js or Gruntfile.coffee used to configure or define tasks and load Grunt plugins

Grunt

// These plugins provide necessary tasks.

grunt.loadNpmTasks('grunt-contrib-jshint');

};
Gruntfile.js
module.exports = function(grunt) {
// Do grunt-related things in here
};
The "wrapper" function
// Project configuration
grunt.initConfig({
pkg: grunt.file.readJSON('package.json'),

Project configuration

jshint: {

Task configuration
// These plugins provide necessary tasks.
grunt.loadNpmTasks('grunt-contrib-jshint');
grunt.loadNpmTasks('grunt-contrib-watch');
// Defines the default task.
