Question: Can you recommend a tool that helps me identify and fix errors in my NodeJs application?

If you're looking for a service to find and fix problems in your Node.js code, N|Solid is a full-featured platform that offers real-time visibility into performance and security problems.

Another good option is Inspector, a code execution monitoring service that spots problems in real time and uses AI to fix them.
