What are Event Listeners? And how can they lead us through the core of D8?


Magic happens. It did in Drupal 7, and it still does in Drupal 8. But NOW, a lot of magic happens via event listeners: little object-oriented pockets of code that we can *actually* understand and debug. Amazing!

In this talk, we'll learn what events are, create a simple event listener, and then use our new dangerous knowledge to start digging into how Drupal 8 *actually* works. Ever wonder where security is applied? Or where Drupal queries for the node? With a little bit of work, you'll be able to find these answers - or anything else - on your own.
