Developing an API without API Platform
summary
Starts from a plain Symfony app (composer require api) and reconstructs API Platform features with a few dozen lines: View listener to serialize controller results, value resolver to deserialize and validate JSON into API models, and a custom ValidationException handled by an EXCEPTION listener that formats violations. Adds a tiny CORS listener, hand‑written SDK, user manual and a React+TypeScript+Redux admin. v0.1 implements the POST/GET review API (about 80% feature parity); it works but maintenance and boilerplate motivate using modern API Platform with pagination, SDK generation and Mercure.
