What are the best practices for managing the Node.js event loop?

What are the best practices for managing the Node.js event loop?

To manage the Node.js event loop effectively, consider these best practices: avoid blocking the event loop, use asynchronous APIs, and leverage worker threads for CPU-intensive tasks.

Can you explain why blocking the event loop is a bad idea?

Blocking the event loop can lead to performance issues, as it prevents other operations from executing, causing delays in handling requests.

What are some common mistakes developers make with the event loop?

Common mistakes include using synchronous code, not handling errors properly, and failing to optimize long-running tasks.

How can I monitor the performance of the event loop?

You can use tools like Node.js built-in diagnostics, the perf_hooks module, or third-party monitoring solutions to track event loop performance.
