Node.js for dummies

Sebastian Domagała

What are we going to talk about today:

  • A bit too short introduction of Node
  • What makes it so easy...
  • ...and why you should be careful
  • Beer-as-a-Service
  • Microservices
  • Q&A

Let's talk Node

Did we even need another programming language?

  • Brings event-driven programming to web servers - no need for threading
  • Lightweight
  • Stateless
  • Non-blocking IO
  • Perfect for microservices
  • NPM

Let's talk Node

Why we use only one thread...
And why it does NOT matter? 




  function przygotujPiwo(chmiel, callback) {
    dodajChmiel(chmiel, function(brzeczka) {
      const temperatura = '10'; //stopnie Celsjusza
      schładzajBrzeczke(brzeczka, temperatura, function(schlodzonaBrzeczka) {
        dodajDrożdżeDoBrzeczki(drożdze, brzeczka, function(piwo) {
          callback(piwo);
        });
      });
    });
  });

So...
let's get our hands dirty

Not the service we deserved, but the one that we needed

Bright future

That's all cool and stuff... but what are the things that might go wrong?

Let's use example:
