Structure a Node.js Express TypeScript backend using a layered architecture that spans routes, controllers, services, and repositories. This enforces type-safety, standardized error handling, and consistent architecture across microservices to reduce duplication and risk.

The best way to validate requests in an Express TypeScript microservice is using Zod. It enforces type-safety and consistent validation patterns across the API, providing practical examples and anti-patterns to help teams scale while avoiding common pitfalls.

Standardize error handling across Node.js microservices by implementing a BaseController pattern. This provides consistent error processing across controllers and integrates Sentry monitoring to unify architecture, improve maintainability, and accelerate delivery.

Yes, you can use Prisma with a layered Express TypeScript architecture. The guide provides comprehensive coverage of Prisma integration within the repository layer to enforce type-safety and consistency across backend services.

Configure dependency injection in a TypeScript backend by applying the guide's standardized patterns. It enforces type-safety and consistent architecture across services, reducing duplication and risk while accelerating microservice delivery.
