Production Node.js backends use layered architecture with controllers, services, and repositories. This Skill covers REST and GraphQL patterns with dependency injection, middleware design, and database integration using Prisma for type-safe data access across SQL and NoSQL stores.

Secure Node.js backends require middleware for authentication, authorization, rate limiting, and input validation. This Skill provides tested patterns for implementing these security layers alongside error handling, logging, and structured data access to protect production services.

Prisma integrates into Express through repository and service layers that abstract database queries. This Skill demonstrates type-safe Prisma patterns with dependency injection, enabling maintainable data access across SQL and NoSQL stores in microservices and REST APIs.

Node.js backends need unit, integration, and worker testing. This Skill provides clear testing patterns across middleware, services, and repositories, ensuring secure, scalable implementations with proper error handling and logging throughout the stack.

Yes. This Skill covers REST APIs, GraphQL backends, and microservices using Express and Fastify. Layered patterns with controllers, services, and repositories work across all three, with shared middleware, auth, and database integration approaches.

Production backends require logging, error handling, and instrumentation. This Skill includes OpenTelemetry patterns alongside middleware and structured logging to monitor and troubleshoot Node.js services at scale.
