Node.js Best Practices

Project Structure

• src/ for source code
• src/lib/ for utilities
• src/types/ for TypeScript types
• tests/ for test files
• Keep entry point minimal

Async Patterns

• Use async/await everywhere
• Handle all promise rejections
• Use Promise.all for parallel tasks
• Use Promise.allSettled when all must complete
• Set timeouts for external calls
• Use AbortController for cancellation
