Node.js, MongoDB and You: Part II

Mitch Pirtle jsDay 2014, Verona Italy - @jsdayit

How many of you watched the first talk?

Ok how many of you are new to Node?

What language do you mainly work with?

Now about me.

Ok my Javascript totally sucks.

About this talk.

Ok, technically there are three talks today.

• Session 1: All about MongoDB (you missed it)

• Session 2: All about Node.js (right now)!

• Session 3: The coolness of both together (next)

Introducing:

Big Node.js things

• Completely javascript based.

• Asynchronous.

• Crazy, whack-daddy fast.

• You gotta learn javascript anyway.

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

What do you mean, operational perspective?

TO THE CONSOLE

Ok so what does it look like?

Most simple example

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

This one repeats what it hears

var net = require('net');!var server = net.createServer(function (socket) { socket.write('Echo server\r\n'); socket.pipe(socket);});!server.listen(1337, '127.0.0.1');

TO THE CONSOLE

But wait, there’s more.

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)

MOAR CONSOLE

Now for the pain.

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.

Remember: You have to master the asynchronous

nature of javascript.

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
