如何记录node.js程序中的每个“抛出”？

Question

I have a quite large js codebase that is run as node.js script. I'd like to log every exception even if it is caught inside the production code.

Is it possible to achieve? I thought about injecting some code inside Error constructor by redefining it, but some parts of code throw custom errors. Redefining all error types from the production code is not feasible, neither is adding logging logic next to every throw statement and/or try-catch block.

The best solution would be to somehow redefine throw keyword - is that possible?

Answer 1

There is an event for unhandled exceptions :

process.on('uncaughtException', function (err) {
  console.log('Caught exception: ' + err);
});
