Choosing a Node.js framework depends on project scale and complexity. Use Fastify or Hono for high-performance APIs, Express for simplicity, and NestJS for structured, large-scale applications requiring robust architecture.

Architectural best practices for Node.js applications involve adopting layered structures, implementing centralized error management, handling async patterns correctly, and enforcing input validation alongside secure coding principles.

Evaluating modern runtimes like Bun and Deno against standard Node.js involves checking native TypeScript support, ESM compatibility, and specific performance targets for your deployment scenarios.

Centralized error handling in Node.js requires capturing asynchronous errors globally and routing them through a unified middleware structure to ensure consistent error responses and secure application behavior.

Structuring a Node.js project for maintainability involves applying layered architectures, separating business logic from routing, and standardizing validation and testing protocols across the application.

Transitioning to ESM from CommonJS in Node.js development is recommended when utilizing modern runtimes, leveraging native TypeScript execution, and requiring compatibility with contemporary framework ecosystems.
