This document provides an overview of Node.js, Express.js, and Jade for building web applications. It also describes how to set up routes and controllers in Node.js and render views using Jade. Code examples are given for creating routes, a user controller, and a profile view. The full source code for a simple Node.js app demonstrating these concepts is provided in a GitHub repository.

6. Start

7. Routs
routes = require('./routes')
user = require('./routes/user')
app.get('/', routes.index); http://localhost/
app.get('/users', user.list); http://localhost/users
app.get('/users/:user', user.profile); http://localhost/users/bill
app.get('/users/:user/pics', user.media);
http://localhost/users/bill/pics

8. Controller
user.js
exports.profile = function(req, res){
res.render('profile',
{
title: 'Profile',
username: req.params.user
}
);
}; // get('/users/:user',user.profile)

9. View
profile.jade
extends layout
block content
h1= title
p This is #{username}'s profile
