GRUNT & GULPBuild Script Automation

Gulp / Grunt• Gulp and Grunt are both task runners (think Ant)• Grunt uses a configuration based approach• Gulp uses streams from Node• Common tasks:

• Compile SASS/Less to CSS• Run JSLint• Minify JavaScript/CSS files

Gulp: Hello World

Gulp: Hello World

Gulp: Configuring IDE Actions

Grunt: Example

Install via npm

Grunt: Install Dependencies

RequireJS

Maps module names to local paths for testing.

NODE.JSServerside JavaScript

What is Node.js?

Node.js is a platform built onChrome’s JavaScript runtime for easily building fast and scalable network applications. Node.js uses an event-driven, non-blocking I/O model that makes it lightweight and efficient, perfect for data-intensive real-time applications that run across distributed devices.

Node.js Runtime• V8 JavaScript Engine is an open source JavaScript

engine developed by Google for the Chrome web browser.

• V8 compiles JavaScript to native machine code (IA-32, x86-64, ARM, etc.) before executing it.

Node.js + Express.js

Template Engines• JADE <- supported natively by NetBeans• EJS• Handlebars• Hogan.js

Node.js Express.js Template Engine

NetBeans & Node.js• Fully integrated support for Node.js• Project wizard for creating new projects• Express generator is integrated• Project specific Node.js settings

UNIT TESTING

Unit TestingSupported Unit Testing frameworks:• Karma• JS Test Driver• MochaDemo• Jasmine – JavaScript unit testing framework

• Tests written in JavaScript• Test synchronous and asychronous JavaScript code

• Karma – JavaScript test runner• Based on NodeJS• Launches and executes tests in web browser

(Chrome/FireFox/etc.)

Karma Configuration & SetupInstalling Karma for a project (from within project directory):• npm install karma --save-dev• npm install karma-jasmine karma-chrome-launcher --

CORDOVA

Introducing Cordova• Originally named PhoneGap.• Mobile development framework• Development started in 2009.• Wraps HTML5 applications in a native

wrapper.• Purchased by Adobe in 2011.• Code donated to Apache as Apache Cordova.

• PhoneGap built on Cordova

• Adobe provides cloud build system for PhoneGap.

CordovaPlatform SDK

• Certificates to test on devices ($$)

Ant (ant.apache.org)NodeJS (nodejs.org)

• Install Apache Cordova (cordova.apache.org)

ChromeJava 8 (java.oracle.com)NetBeans 8.0.1 (netbeans.org)What might we want to install? Maven (maven.apache.org)

Karma (karma-runner.github.io)Jasmine (jasmine.github.io)Grunt (gruntjs.com)
