How can I troubleshoot performance issues in my Node.js application?
Start by identifying the bottlenecks. Use tools like Node.js built-in profiler or third-party tools like PM2.
What specific metrics should I look at to identify these bottlenecks?
Focus on CPU usage, memory consumption, event loop delays, and response times for your API endpoints.
Are there any common coding practices that can lead to performance issues?
Yes, avoid blocking the event loop, use asynchronous programming, and minimize synchronous I/O operations.
Can you recommend any libraries or tools for monitoring performance?
Sure! Consider using APM tools like New Relic, Datadog, or open-source options like Prometheus with Grafana.
