Symfony 4: A new Way to develop Applications
summary
Symfony 4 centers on Flex recipes (Composer plugin) that auto-add config and wiring so projects start small, grow only what you need using the Symfony skeleton or the Symfony client; bundles are now for third‑party libraries only, services default to autowiring and private services, parameters move to .env, Webpack Encore standardizes assets, and the messenger component adds first‑class queue support. Codebase drops ~70% vs older editions and a headline “hello world” benchmark shows ~3x speed vs Laravel, upgrade via 3.4.
