1. Code Optimization 🔧

  • Use asynchronous functions (async/await) to avoid blocking the event loop.
  • Optimize database queries with indexing and caching.
  • Minimize memory leaks by properly managing require and import statements.

2. Performance Tuning ⚙️

  • Enable Node.js cluster module for multi-core CPU utilization.
  • Use process.nextTick() or setImmediate() for microtask scheduling.
  • Reduce garbage collection pressure by reusing objects and avoiding unnecessary allocations.

3. Resource Management 💾

  • Leverage caching strategies like Redis or Memcached for frequent data access.
  • Optimize file I/O with fs.promises and streaming for large files.
  • Monitor memory and CPU usage using tools like perf or node --inspect.

4. Advanced Tips 📚

  • Use Web Workers for CPU-intensive tasks.
  • Enable HTTP/2 for faster request-response cycles.
  • Profile code with v8 tools to identify bottlenecks.
