nodejs-best-practices

Node.js architecture should use a layered structure with Controller, Service, and Repository separation. This design separates business logic from routing and data access, improving maintainability and scalability for complex applications.

Common Node.js anti-patterns include poor async patterns, scattered error handling, and missing validation. Refactoring should centralize error handling and apply structured architecture principles to eliminate these structural flaws.

Use NestJS for enterprise applications requiring structured architecture and dependency injection, while Fastify is preferred for performance-critical services where low overhead and high throughput are the primary deployment targets.

The best way to handle asynchronous operations in Node.js is to implement centralized error handling and structured async patterns. This approach captures errors consistently across the application layer and prevents unhandled rejections.

Node.js architecture scales for edge deployment targets by selecting appropriate frameworks like Hono and applying performance-focused best practices. Layered design and async patterns ensure reliable execution in distributed environments.
