Focus on fun stuff!
The JavaScript Task Runner
✓ Node ✓ JS/Coffee + JSON ✓ Focus on web
development ✓ Over 2,294 plugins! Things to love about Grunt:
None
Who’s using it? And some more: Wordpress, Opera, etc.
$ npm install -g grunt-cli - package.json - Gruntfile.(js|coffee) Getting
started: Installation: Requirements:
{ "name": "MyAwesomeApp", "version": "0.0.1", "private": true } package.json $
npm install grunt --save $ npm install grunt-contrib-uglify --save $ npm install grunt-contrib-cssmin --save ... $ cat package.json { "name": "MyAwesomeApp", "version": "0.0.1", "private": true, "dependencies": { "grunt": "~0.4.2", "grunt-contrib-uglify": "~0.3.2", "grunt-contrib-cssmin": "~0.8.0" } } Install dependencies:
CSS Minification
module.exports = function(grunt) { grunt.initConfig({ pkg: grunt.file.readJSON('package.json'), cssmin: { styles:
{ files: { 'static/css/app.min.css': ['src/css/*.css'] } } } }); grunt.loadNpmTasks('grunt-contrib-cssmin'); grunt.registerTask('default', ['cssmin']); }; Gruntfile.js Lets run it! $ grunt
JS Minification
module.exports = function(grunt) { grunt.initConfig({ pkg: grunt.file.readJSON('package.json'), cssmin: { styles:
{ files: { 'static/css/app.min.css': ['src/css/*.css'] } } }, uglify: { scripts: { files: { 'static/js/app.min.js': [ 'src/js/jquery.js', 'src/js/plugins.js', 'src/js/app.js' ] } } } }); grunt.loadNpmTasks('grunt-contrib-cssmin'); grunt.loadNpmTasks('grunt-contrib-uglify'); grunt.registerTask('default', ['cssmin']); grunt.registerTask('deploy', ['cssmin', 'uglify']); }; Gruntfile.js: Lets run it! $ grunt deploy
Concatenate on development + minify on deploy
module.exports = function(grunt) { grunt.initConfig({ ... concat: { dist: {
src: ['src/js/**/*.js'], dest: 'static/js/app.all.js' } }, uglify: { scripts: { files: { 'static/js/app.min.js': ['static/js/app.all.js'] } } } }); ... grunt.loadNpmTasks('grunt-contrib-concat'); grunt.registerTask('default', ['cssmin', 'concat']); grunt.registerTask('deploy', ['cssmin', 'concat', 'uglify']); }; Gruntfile.js: Lets run it! $ grunt deploy Install plugin: $ npm install grunt-contrib-concat --save
What about SASS? Updated project structure: $ tree . .
