Structure your Node.js Express microservice using a layered architecture that separates routes, controllers, services, and repositories. This pattern enforces clean separation of concerns, ensuring maintainability and consistency across backend projects.

The BaseController pattern standardizes request handling in backend API development by abstracting common logic into a base class. It streamlines controller creation in Express and TypeScript, ensuring established architectural patterns are consistently applied.

Validate API request inputs in Express using Zod by defining schema objects for your data. This Skill provides guidelines for integrating Zod to enforce type safety and runtime validation, preventing invalid data from reaching services.

Yes, you can use Sentry for error handling in Node.js microservices. This Skill provides guidelines for integrating Sentry to capture and monitor exceptions, ensuring robust error tracking across your Express backend architecture.

The best way to manage configuration in a TypeScript Express application is using a unifiedConfig approach. This standardizes environment variables and settings, ensuring secure and maintainable configuration management across microservices.

Implement dependency injection in an Express backend by passing service instances directly to controllers or routes. This approach decouples component creation, enhancing testability and maintaining the clean layered architecture of your microservices.
