Node.js Memory Leak Guide
Coming Soon
This comprehensive guide for Node.js memory leak detection and prevention is currently being developed.
We welcome contributions from the community! If you'd like to help write this guide, please:

This guide will cover:
- Node.js-specific memory leak patterns
- V8 heap analysis and optimization
- Production monitoring and alerting
- Framework-specific considerations
- Microservices memory management
What Will Be Covered
Node.js Memory Management
- V8 JavaScript engine internals
- Event loop and memory implications
- Buffer and stream memory handling
- Cluster mode considerations
Common Node.js Memory Leak Patterns
- Event emitter listener accumulation
- Unclosed file descriptors and streams
- Global variable accumulation
- Closure-based memory retention
- Promise chain leaks
- Buffer allocation without cleanup
- Database connection pool leaks
Node.js-Specific Tools
- Node.js Inspector (--inspect flag)
- Clinic.js - Performance monitoring suite
- 0x - Single-command flamegraph profiling
- heapdump - Heap snapshot generation
- memwatch-next - Memory usage monitoring
- Chrome DevTools for heap analysis
Framework Considerations
- Express.js middleware memory patterns
- NestJS dependency injection and memory
- Fastify plugin memory management
- Socket.io connection handling
- GraphQL resolver memory patterns
Production Monitoring
- PM2 memory monitoring
- Docker container memory limits
- Kubernetes memory management
- APM tools integration (New Relic, DataDog)
- Custom health check endpoints
Performance Optimization
