Debugging memory leaks in Node.js: a complete guide
Memory leaks in Node.js can turn a performant application into a nightmare.
1. Identifying the symptoms
Memory leaks in Node.js applications often manifest insidiously. The first sign is usually a gradual increase in RAM consumption over time.
2. Diagnostic tools
Chrome DevTools remains the tool of choice for diagnosing memory leaks in Node.js. By launching your application with the --inspect flag, you gain access to the built-in memory profiler.
3. Remediation strategies
Once the leak has been identified, apply the principle of least privilege: release references as soon as they are no longer needed, and use WeakRef for caches.
Configuring an API Gateway with rate limiting
Protect your APIs with a robust gateway featuring rate limiting, authentication and monitoring.
Measuring your PostgreSQL query results
Optimise your PostgreSQL queries with EXPLAIN ANALYZE and built-in profiling tools.
