HTTP Patterns: PSR 7 & 15 By Example
summary
Live coding shows PSR-7 request/response objects as immutable, how to evolve them with with methods, and how streams can be detached and transformed; PSR-15 middleware takes a ServerRequest and a handler so a simple middleware stack handler runs route, auth and logging middleware in order. The demo builds a tiny weather/traffic API, adds logging and bearer-token auth, emits responses with Laminas emitters, and uses the Tortilla/Burrito wrapper to add convenience methods — everything runs and is easy to unit test.
