Node.js Introduction

How did you set up a web site 10 years ago?

• Perl? ASP? PHP?
• Windows server? Linux server?
• VBScript? JScript

I was working on:

• DVBBS
• Windows Server 2000
• VBScript + JScript

I needed to know:

• ASP (VBScript)
• Windows Server 2000 + IIS
• VBScript + JScript

I need to know:

• Client-Side JavaScript
• Server-Side JavaScript (Node.js)

				var http = require('http');
				var server = http.createServer(function(request, response) {
				    response.send('Hello, world!');
				});
				var port = 3000;
				server.listen(port);
			

• No configuration for Apache or alike
• No URL routing? You will see.

It's just like Rails or other MVC framework. It supports:

• String definition
• RegExp definition

• Routing
• Middleware
  • Logger
  • Body Parser
  • Method Override
  • Cookie Paser
  • Session
• Templating Engine
• Static Content

1. Use module.exports to write modules
2. Provide package.json and index.js
3. npm publish (use npm adduser for the first time)

• Heroku
• Joyent no.de
• CloudFoundry
• Nodester

1. gem install heroku (for the first time)
2. heroku create --stack cedar to create an app
3. Put web: node web.js in a file named Procfile
4. Make sure that package.json is correct
5. git push heroku
6. heroku ps:scale web=1 to set web process number to 1

Please read this guide for more details.

Replacement of Apache, Lighttpd, etc?

Replacement of ASP, PHP, Rails, etc?

• More users
