Setup

There are two ways to setup Express.

1).The first one is by placing it in your package.json file and running npm install.

{ "name": "MyWebSite", "description": "My website", "version": "0.0.1", "dependencies": { "express": "3.x" } } The framework's code will be placed in node_modules and you will be able to create an instance of it.

$ npm install

2). Just install Express globally with "npm install -g express". By doing this, you now have a brand new CLI instrument. For example if you run:

"express --sessions --css less --hogan app"

Express will create an application skeleton with a few things already configured for you. Here are the usage options for the express(1) command:

Usage: express [options] Options: -h, --help output usage information -V, --version output the version number -s, --sessions add session support -e, --ejs add ejs engine support (defaults to jade) -J, --jshtml add jshtml engine support (defaults to jade) -H, --hogan add hogan.js engine support -c, --css add stylesheet support (less|stylus) (defaults to plain css) -f, --force force on non-empty directory

If you want to generate an application with EJS, Stylus, and session support you would simply execute:

$ express --sessions --css stylus --ejs myapp

create : myapp create : myapp/package.json create : myapp/app.js create : myapp/public create : myapp/public/javascripts create : myapp/public/images create : myapp/public/stylesheets create : myapp/public/stylesheets/style.styl create : myapp/routes create : myapp/routes/index.js create : myapp/views create : myapp/views/index.ejs

install dependencies: $ cd myapp && npm install

run the app: $ node app

Steps i followed

1)."npm install -g express" => If you install express globally with npm you'll have it available from anywhere on your machine.

2).export PATH=/usr/local/share/npm/bin:$PATH in ~/.zshrc

3).express --help

4).express -s demoApp

5).cd demoApp

6).npm install => downloads all the dependencies provided in package.json , and then a node_modules folder will pop up.

7).node app => starts the app

npm install -g nodemon

nodemon app.js => will automatically reflect ur changes

Configuration

site should be deployed to three different places - a local server, a staging server and a production server.

As you know, every node script is run as a console program. So, we can easily send command line arguments which will define the current environment.

I wrapped that part in a separate module /config/index.js

read about modules in ModulesReadMe.txt

Now add

var config = require('./config')();

http.createServer(app).listen(config.port, function(){ console.log('Express server listening on port ' + config.port); });

8). node app.js prod

Tests

npm install -g jasmine-node

create a tests directory which will hold our tests

The spec files must end with .spec.js, so the file should be called config.spec.js.

jasmine-node --verbose ./tests => Run Tests
