Symfony — Visual Backend Explanations

Symfony, explained visually.
Diagrams + mental models + real code paths.

This hub is a curated path through Symfony internals. I’m starting with fundamentals and then going component-by-component.

Learning path

1) Foundations

• Request → Kernel → Controller → Response
• Routing and controller resolution
• Error handling and exceptions

2) Components

• HttpFoundation (Request/Response, headers, cookies, sessions)
• DependencyInjection (autowiring, compilation, config)
• EventDispatcher (kernel events and flow)
• Messenger (handlers, transports, retries)
• …and more

3) Production engineering

• Performance profiling and bottlenecks
• Caching strategies
• Testing strategy for Symfony apps
