"Deep Dive into Symfony's Dependency Injection Component"

on YouTube ↗49m

" summary

Symfony's DependencyInjection component compiles YAML into optimized PHP factories, supports auto-wiring via PHP 8 constructor types and attributes, and removes or inlines unused services so the container stays small and fast. It implements PSR-11, treats services as singletons by default, and uses service tags plus autoconfigure to collect implementations (example: CSV column transformers) and a decorator-based HTTP client to intercept requests; the described patterns are shown working end-to-end.
