Mastering Symfony 4's Dependency Injection

Workshop abstract

The Dependency Injection component is the spine of any Symfony apps. With Symfony 4, you should not be using the container directly in any parts of your src/ folder. In an apparent paradox, the container is now invisible from your code, allowing to create really decoupled classes that have little to no coupling with Symfony - the framework. In this workshop, I propose we review together 1. how automation works so you won't ever consider it "magic" 2. how to leverage configuration to create e.g. scoped service locators, named autowiring aliases, tagged iterators, and learn what all these beasts are if you don't ;)
