nodejs-best-practices

Choosing a Node.js framework depends on performance needs, team familiarity, and ecosystem requirements. Evaluate options like Express, Fastify, NestJS, or Hono using a decision tree based on your specific architectural constraints and project scale.

Node.js architecture best practices emphasize layered structures, robust error handling, and secure async patterns. Context-driven choices for validation and testing ensure application stability and maintainability.

Choosing ESM or CommonJS for API development depends on your runtime environment and native TypeScript requirements. Modern Node.js applications often favor ESM for better compatibility with edge deployments and current ecosystem standards.

Node.js, Bun, and Deno offer different runtime considerations for high-performance APIs. Selecting between them requires evaluating native TypeScript support, module system compatibility, and specific ecosystem requirements.

Use Fastify instead of Express when building high-performance APIs requiring lower overhead and faster execution. Express remains viable for projects prioritizing ecosystem maturity and team familiarity over raw benchmark speed.

TypeScript significantly enhances Node.js architecture by providing type safety for validation and async patterns. While not strictly required, it is highly recommended for robust, maintainable applications across modern runtimes.
