This document provides information about Node.js, Express, and using Node.js with databases like MySQL. It describes Node.js as a JavaScript web framework that is fast and small. It explains that Express is a web application framework built on Node.js and Connect. It provides instructions for installing Express and a quick start guide. It also lists features of Express like routing, views, and sessions. Finally, it discusses hosting Node.js applications on platforms like Heroku and connecting Node.js to MySQL.

- 3. EXPRESS WEB FRAMEWORK • Insanely fast (and small) • server-side JavaScript web development framework • built on • [node](http://nodejs.org) • [Connect](http://github.com/senchalabs/connect)
- 4. var app = express.createServer(); app.get('/', function(req, res){ res.send('Hello World'); }); app.listen(3000);
- 5. INSTALL npm install express npm install -g express
- 6. QUICK START • Create the app: •$ npm install -g express •$ express /tmp/foo && cd /tmp/foo
- 7. QUICK START • Install dependencies: •$ npm install -d • Start the server: •$ node app.js
- 8. STRUCTURE
- 9. FEATURES * Robust routing * Redirection helpers * Dynamic view helpers * Content negotiation * Focus on high performance * View rendering and partials support
- 10. FEATURES * Environment based configuration * Session based flash notifications * Built on [Connect](http://github.com/senchalabs/connect) * High test coverage * Executable for generating applications quickly * Application level view options
- 11. FEATURES VIA CONNECT * Session support * Cache API * Mime helpers * ETag support * Persistent flash notifications * Cookie support * JSON-RPC * Logging * and _much_ more!
