About This Architecture

Node.js Express REST API sequence diagram with JWT authentication, request validation, and multi-layer caching. Client requests flow through Auth Middleware (JWT verification), Joi schema validation, Express Controller, Service Layer, Redis cache, and MongoDB persistence. The diagram illustrates four execution phases: user authentication with token generation, paginated item fetches with Redis caching, PATCH updates with validation, and centralized error handling with structured logging. Fork this diagram to customize authentication strategies, add rate limiting, or integrate OCI Object Storage for file handling.

How should I structure a Node.js Express REST API with authentication, caching, and database persistence?

This sequence diagram shows a production-grade architecture where Client requests pass through JWT Auth Middleware, Joi Validation, Express Controller, and Service Layer before hitting Redis Cache or MongoDB. Four phases cover authentication token generation, cached page item fetches, PATCH updates with validation, and centralized error logging.
