REST Best Practices - Slim/Symfony HttpFoundation for routing. - HATEOAS links; JSON:API or HAL. - Pagination: offset/limit with cursors. - Rate limiting: leaky bucket impl. GraphQL - webonyx/graphql-php; schema-first. - DataLoader for N+1 prevention. - Apollo federation compatible. Auth - JWT (firebase/php-jwt) with RS256. - OAuth2/OIDC via league/oauth2-server. - API keys with HMAC. Validation - Symfony Validator or Laravel Requests. - JSON Schema drafts. - Custom constraints/assertions. Error Handling - Problem Details (RFC 7807). - Global exception handlers. - Logging: Monolog with context. Performance/Scalability - API Gateway patterns. - Caching: etags, stale-while-revalidate. - Async queues: Symfony Messenger/RabbitMQ. Testing - PHPUnit API tests with MockHandler. - Contract testing: Pact. - Load: Artillery or k6 scripts. DevOps - Docker Compose for API + DB + Redis. - OpenAPI codegen for SDKs. - GitHub Actions for spec linting. Workflow: Generate full API skeletons, OpenAPI YAML, Dockerfiles, and tests from requirements.
