    projects

15. Grunt.js is used for Concatenation Testing with headless browsers JS

    linting basically, whatever

16. Installation $ npm install -g grunt-cli Install the grunt cli

    tool

17. Installation Edit your package.json file { "name": "my-project-name", "version": "0.1.0",

    "devDependencies": { "grunt": "~0.4.2", "grunt-contrib-jshint": "~0.6.3" } } grunt.loadNpmTasks(‘grunt-contrib-uglify'); Then in your Gruntfile.js add

18. Gruntfile.js module.exports = function(grunt) { ! // Project configuration. grunt.initConfig({

    pkg: grunt.file.readJSON('package.json'), uglify: { options: { banner: '/*! <%= pkg.name %> <%= grunt.template.today("yyyy-mm-dd") %> */\n' }, build: { src: 'src/<%= pkg.name %>.js', dest: 'build/<%= pkg.name %>.min.js' } } }); ! // Load the plugin that provides the "uglify" task. grunt.loadNpmTasks('grunt-contrib-uglify'); ! // Default task(s). grunt.registerTask('default', ['uglify']); ! };

19. Concatenating module: grunt-contrib-concat concat: { ‘assets/js/main.js’: [ ‘js/libs/jquery.js’, ‘js/libs/underscore.js’ ‘js/libs/backbone.js,

    ‘js/src/app.js’], ‘assets/css/style.css’: [ ‘css/bootstrap.css’, ‘css/main.css’] }

20. Compiling LESS module: grunt-contrib-less less: { dashboard: { files: {

    "css/main.css": "less/style.less", "css/landing.css": "less/landing.less", } } }

21. Running specs #1 module: grunt-contrib-jasmine jasmine: { src: [ 'specs/project.js'],

    options: { host: 'http://localhost:7000/', vendor: [ ‘libs/jquery.js’], helpers: [ 'specs/jasmine-jquery/lib/jasmine-jquery.js', ‘specs/bower_components/sinonjs/sinon.js' ], template: 'specs/index.tmpl', specs: 'specs/build/specs.js', keepRunner: true } },

22. Running specs #2 module: grunt-contrib-connect connect: { server: { options:

    { port: 7000 } } } grunt.registerTask('specs', ['connect', 'jasmine']); Registering our custom “specs” tasks

23. Watching files module: grunt-contrib-watch watch: { gruntfile: { files: '<%=

    jshint.gruntfile.src %>', tasks: ['jshint:gruntfile', 'concat', 'less'] }, less: { files: “less/**/*.less”, /* or use an array */ tasks: [‘less’, ‘concat’] }, specs: { files: “specs/**/*Specs.js” tasks: [‘specs’] } }

24. Live reload module: grunt-reload reload: { port: 6001, proxy: {

    host: 'localhost' } }, watch: { less: { files: “less/**/*.less”, /* or use an array */ tasks: [‘less’, ‘concat’, ‘reload’] } }

25. bower a package manager for the web

26. Installation $ npm install -g bower Install the bower tool

27. Usage $ bower install <package> Install the bower tool $

    "version": "1.0.0", "main": "path/to/main.css", "ignore": [ ".jshintrc", "**/*.txt" ], "dependencies": { "<name>": "<version>" }, "devDependencies": { "<test-framework-name>": "<version>" } }
