nodejs-backend-patterns

Structure a Node.js backend using a layered architecture that separates controllers, services, and repositories. This pattern ensures maintainable microservices by isolating business logic from API routes and database operations.

Implement JWT authentication and robust error handling in Express.js using custom error classes and a global error handler. This approach standardizes middleware validation and secures RESTful API endpoints effectively.

Yes, the Node.js backend patterns support database integration with both PostgreSQL and MongoDB. The repository layer abstracts data access, allowing your RESTful APIs to interact seamlessly with either database system.

Set up rate limiting and caching strategies for Fastify by configuring dedicated middleware within the API pipeline. These mechanisms protect RESTful endpoints from excessive traffic and improve microservices response times.

Yes, you can use dependency injection to decouple Node.js API development components. This pattern allows you to pass services into controllers dynamically, making your Express.js or Fastify backend highly testable and modular.

Implement a layered architecture over standard Express.js route definitions when building scalable microservices. This structure separates API routing from business logic and database integration, preventing unmanageable codebases as your application grows.
