Outline
 Server Side Javascript
 Environment Preparation
 Static Check & Unit Test

NodeJs
 Javascript is a frontend programming language,
but things have changed...

Server Side Javascript
 Server Side Javascript needs:
 Package management and Modular
 Task Management Tools, like maven in java;
 Quality Assurance Utilities
− Static Check
− Unit Test

Writing Modular JavaScript
 Modularity
 AMD: Asynchronous Module Definition
define(
module_id /*optional*/,
[dependencies] /*optional*/,
definition function /*function for instantiating the module or object*/
);

Package Management
NPM is short for Node Packaged Modules.

Grunt.js
 Why a build tool is needed for CI ?
 Why Grunt.js

Basic Grunt.js tasks
 init
Generate project scaffolding from a predefined template
 lint
validate files with jshint
 min
minify files with UglifyJS
 server
Start a static node web server
 test
Run unit tests with nodeunit. (Jasmine support)

Install NodeJs
 Install via source code
 Download from
nodejs.org/download
 ./configure & make & make install
 Install via package manager
su -c 'yum install npm'
 Dependencies
 V8 Javascript Engine

Install Related Modules
 npm install -g grunt-cli
 npm install -g grunt-contrib-jshint
 npm install -g grunt-mocha-
phantomjs

Mocha
 Feature Rich
 Runs on node + the browser
 Simplifies async testing
 Growl notifications
 Choose your own assertion library

Chai
 BDD / TDD
 For node + the browser
 Three assertion styles
 should - foo.should.be.a('string')
 expect - expect(foo).to.be.a('string')
 assert - assert.typeOf(foo,'string')
