The backend skill helps you build reliable, maintainable HTTP APIs end-to-end by enforcing validation, layered architecture, consistent error handling, and pragmatic database/cache/async patterns.
Provide your endpoint requirements and constraints (auth method, request/response shapes, data model) and ask for a layered Hono or Go chi implementation including validation, error responses, and the repository/service split.

A production-ready HTTP API requires a layered architecture separating routers, handlers, services, and repositories. This structure enforces consistent error handling, isolated business logic, and maintainable database operations across Hono or Go chi implementations.
Backend validation is best handled using Zod for input schemas alongside a robust AppError hierarchy. This combination ensures consistent error responses, explicit request IDs, and graceful failures across your HTTP API endpoints.
Avoid N+1 queries in PostgreSQL by using query composition and transaction boundaries within your repository layer. This approach ensures transaction-safe database operations and optimized data fetching.
Yes, Redis and BullMQ are used for background jobs in Node or Bun backends. This setup enables cache-aside patterns, retry queues, and event-driven orchestration for asynchronous processing.
Yes, this backend architecture supports typed JWT auth middleware. It integrates directly into the HTTP API layer to secure endpoints and manage authentication flows seamlessly.
Separate repository and service layers whenever building production-grade HTTP APIs to isolate data access from business logic. This split prevents N+1 queries, clarifies transaction boundaries, and maintains clean code.
