2. 1. Background
2. jQuery, Prototype, Firebug and others
3. Node.js

3. HTML, JavaScript, DHTML and that’s all.

4.  Gmail and Ajax.
 Introduction of jQuery, Prototype and other
JS frameworks.
 Birth of Firebug

5.  The first incarnations of JavaScript lived in
browsers. Node.js really is just another
context: it allows you to run JavaScript code
in the backend, outside a browser.
 In 2009 Ryan Dahl created a framework that
appeared to propose an answer to the
technical challenge of interacting with a large
web audience in real-time.

6. 1. Google's V8 VM
2. libev
3. libeio

7.  Node leverages a number of existing open-
source projects: most importantly Marc
Lehmann's libev and libeio C libraries and
Google's V8 JavaScript engine. The libev and
libeio C libraries handle the intricacies of
event-driven networking and input/output
while the V8 engine allows Node to be
programmed using JavaScript.

8.  Node is conceptually composed of three
layers of functionality:
 The underlying core engine, a number of core
modules that add provide utility functions
and APIs, and community-created modules
for everything else.

10. 1. Installation
2. Hello World

11.  Node.js is really two things: a runtime
environment and a library.
 To install:
https://github.com/joyent/node/wiki/Installation
 Linux: apt-get, rpm or make.
 Windows: untar the package and run exe.

12. var http = require("http");
http.createServer(function(request, response) {
console.log("Request received.");
response.writeHead(200, {"Content-Type":
"text/plain"});
response.write("Hello World");
response.end();
}).listen(8888);

13.  WhiteBoard
 Google Docs Excel
 Trello – Project Collaboration Tool

14.  Audience questions.
