Nodejs Backend Patterns
Build production-ready Node.js backend services with Express/Fastify, implementing middleware…
A production-grade pattern set for building scalable Node.js backends with Express or Fastify, fully written in TypeScript. It covers layered architecture (controller/service/repository), dependency injection, multi-layer security middleware, robust error handling, database integration, and resilience patterns like circuit breakers and connection pooling. Build APIs that survive real traffic, not just demos.

The skill assembles a Node.js service in a fixed order, security pipeline first, layers second, failure handling last. This is the actual build sequence:
- Pick the framework by requirement, not popularity: Fastify for throughput-critical APIs (2-3x Express), Express for ecosystem breadth, both bootstrapped with structured logging
- Stack the 5-layer request pipeline in order: Helmet header hardening, CORS origin whitelist, Redis-backed rate limiter (stricter limits on auth routes), JWT auth middleware, then Zod validation of body, query and params
- Split the code into layers with dependency injection: controllers handle HTTP only, services own business logic, repositories own SQL, a DI container wires singletons like the connection pool
- Define custom error classes (ValidationError 400, NotFoundError 404, UnauthorizedError 401) and a single global error handler that logs unexpected errors and never leaks stack traces in production
- Configure the PostgreSQL connection pool with timeouts, wrap multi-step writes in BEGIN/COMMIT/ROLLBACK transactions, and release clients in finally blocks
- Finish with resilience: layered caching (in-memory, then Redis), circuit breakers on every third-party call with defined fallbacks, and graceful shutdown that drains requests and closes the pool on SIGTERM

-
Does it force a choice between Express and Fastify?
No, both get production-ready setup templates. The deeper layers, service and repository structure, dependency injection, error hierarchy, Redis caching, are framework-neutral, so the framework choice stays a swap at the edge rather than a rewrite of the core.
-
How does the circuit breaker actually protect my API when a third party goes down?
External calls are wrapped so consecutive failures trip the breaker, which short-circuits further calls and serves a fallback instead of stacking up timeouts. Combined with connection pooling and workload isolation, one dying dependency or one heavy query can't starve every other request.
-
Can I use these patterns in serverless functions?
Mostly no. The patterns assume long-running server processes: connection pools, warm Redis clients, and middleware chains that amortize their setup cost. In a cold-start, per-invocation world the pooling and caching math changes fundamentally, so serverless needs different plumbing.
