Choosing a Node.js framework requires evaluating project context through decision trees that weigh architecture layering, testability, and scale. This guidance applies practical selection criteria to match frameworks with specific small to large project requirements.

The best way to structure Node.js architecture is using a layered design with controller, service, and repository layers. This separation improves testability and future-proofs applications by isolating business logic from runtime and framework concerns.

Deciding between ESM and CommonJS involves evaluating runtime system choices based on Node.js versions and project dependencies. Context-driven reasoning helps determine which module format aligns with your architecture and tooling requirements.

Node.js security practices and validation patterns should be applied using practical decision criteria rather than memorized rules. Guidance covers anti-patterns, error handling, and security principles tailored to your specific application context.

You should avoid specific Node.js async patterns when they conflict with your project's error handling and architecture layering requirements. Context-driven decision trees help identify anti-patterns and select appropriate asynchronous processing approaches.
