Is there a Node.js equivalent of Java UncaughtExceptionHandler?

Question

I had some problematic code in a Node.js application which caused an error (manifested as strange output) but not a total crash. It displayed nothing in the console to indicate an error occurred, and I only identified the root cause by a lot of trial and error in commenting out lines selectively.

To save time in future, is there anything like Java's UncaughtExceptionHandler in Node that will catch anything that's causing errors and display them in the console so I can pinpoint bug(s) immediately?

Answer 1

Yes. You can listen for that event by doing this

process.on('uncaughtException', (err) => {

});

It will override the default behaviour of exiting.
