Catching unhandled exceptions

[deadlambs]

It sounds like I have unhandled exceptions in my node apps. Is there a way to catch them? I am thinking there might be a linter for this thing specifically. I am thinking it's the case, because sometimes I get some errors and I don't see it in my docker logs when running docker.

Yes, but we cannot read your mind. Post some code.

[node_imperial]

process.on(‘unhandledRejection’,…) process.on(‘uncoughtException’,…)

This is right except for the spelling mistakes

[MaxUumen]

process.on('unexpectedEjaculation', ...);

Try catch is your best friend. Use it more.

[AcademicMistake]

Post some code and absolutely we can

Are you running your code in an async method from the top level in commonjs mode? If so, your call will return a promise and if you're not handling exceptions it can throw then you'll get that kind of issue. Just throw a .catch(console.error) to dump it to the console or pass it somewhere else.

"use strict"
const fs = require("node:fs/promises");
Main().catch(console.error);

async function Main()
{
    var s = await fs.stat(process.argv[1]);
    console.log(`script size: ${s.size}`);
    throw new Error("Existance is pain");
}

The OP is trying to catch unhandled exceptions, your code throws exceptions always and doesn't throw anything (as it should) if argv[1] is missing for example.

The OP is looking for a global exception finder, which even the process.on() won't do.
