This is the second of a three-part series on MongoDB and Node.js at jsDay in Verona Italy 2014.

1. Node.js, MongoDB
and You: Part II
Mitch Pirtle
jsDay 2014, Verona Italy - @jsdayit

2. How many of you
watched the first talk?

3. Ok how many of you
are new to Node?

4. What language do you
mainly work with?

5. Now about me.

6. Mitch Pirtle
• Recovering Joomla! founder
• Mongo Master
• Starting companies since
1995
• Musician, skate punk, football
coach
• American idiot living in Turin

7. Ok my Javascript
totally sucks.

8. About this talk.

9. Ok, technically there
are three talks today.

10. • Session 1: All about MongoDB (you missed it)
• Session 2: All about Node.js (right now)!
• Session 3: The coolness of both together (next)

11. Introducing:

12. Big Node.js things
• Completely javascript based.
• Asynchronous.
• Crazy, whack-daddy fast.
• You gotta learn javascript anyway.

13. More Node.js things
• Express is the most common framework
• Many others to choose from
• Excellent from an operational perspective
• Great build tools for css and assets

14. What do you mean,
operational perspective?

15. TO THE CONSOLE

16. Ok so what does it
look like?

17. Most simple example
var http = require('http');
http.createServer(function (req, res) {
res.writeHead(200, {'Content-Type': 'text/plain'});
res.end('Hello Worldn');
}).listen(1337, '127.0.0.1');
console.log('Server running at http://127.0.0.1:1337/');

18. This one repeats what it
hears
var net = require('net');
!
var server = net.createServer(function (socket) {
socket.write('Echo serverrn');
socket.pipe(socket);
});
!
server.listen(1337, '127.0.0.1');

19. TO THE CONSOLE

20. But wait, there’s more.

21. Many frameworks and
stacks to choose from
• Express - the most common framework for Node
• MEAN.js - MongoDB, Express, AngularJS and
Node
• ng-kickstarter - Better hooks for developers
(SASS, Zurb, Grunt, API proxy, and more)

22. MOAR CONSOLE

23. Now for the pain.

25. Asynchronous
• Well that was not intuitive.
• You spend a lot of time making asynchronous
code act like a synchronous application.
• You’re doin’ it RONG.

26. Remember: You have to
master the asynchronous
nature of javascript.

27. There’s plenty of docs!
• …from eight months ago
• …that are no longer functional
• …and probably didn’t work very well back then
• Today’s blog post is tomorrow’s broken example
• When stack overflow is your go-to resource,
there’s a problem
