backend-dev-guidelines

Standard backend patterns for Node.js and Express services organize code into routes, controllers, services, and repositories. This structure separates request handling from business logic and data access to standardize architecture across microservices.

To structure a TypeScript backend project, apply a defined directory layout with clear naming conventions for routes, controllers, services, and repositories. This enforces consistent architecture and governance across Node.js and Express microservices.

Yes, this backend development approach works specifically for microservices. It provides structured architecture guidance, reusable templates, and checklists that speed up feature delivery and onboarding across Node.js, Express, and TypeScript microservices.

The best way to standardize error handling and observability in Express is by applying clear patterns for instrumentation, such as Sentry, alongside structured testing workflows. This ensures consistent governance and monitoring across services.

To start applying these backend guidelines, read the architecture-overview and routing-and-controllers documentation, then implement the structured directory layout, naming conventions, and templates into your existing Node.js and TypeScript services.
