Deep dive into Symfony 4 internals
summary
A tiny framework replicates Symfony 4 internals end to end: PSR-7 requests and responses, an event loop middleware runner, a router that optimizes static vs dynamic routes into a single-fat-regex router, a compiled service container with autowiring that prunes unused private services, middleware for file or void caching plus a cache data collector and toolbar, and a token-storage-plus-voter security layer. The demo runs live and works; PSR-7 implementation is ~2k LOC versus ~5k in Guzzle.
