nodejs-best-practices

To choose a Node.js framework, evaluate deployment targets, performance needs, and team skills. This Skill guides selection between Hono, Fastify, NestJS, and Express to match your specific serverless or edge API constraints.

The best way to structure a Node.js API is applying a layered architecture with controller, service, and repository boundaries. This pattern separates concerns, ensuring consistent validation and robust error handling across your application.

To handle errors consistently in a Node.js application, implement clear error mapping and validation boundaries within your service layers. This Skill provides decision-tree guidance to standardize error handling and reduce maintenance risk.

To avoid blocking the Node.js event loop, select async patterns that minimize synchronous heavy computation. This Skill guides appropriate async pattern selection to keep your high-performance services responsive and stable.

Yes, you can use this Node.js architecture guidance for legacy-compatible applications. It provides decision-tree-based recommendations for evolving APIs and server runtimes, including layered services and validation suitable for legacy environments.

Your Node.js API testing strategy should balance unit, integration, and E2E tests based on your architecture. This Skill helps determine the right testing approach to reduce bugs and insecurity across your server runtime components.
