EventEmitter.errorMonitor - Node documentation
property EventEmitter.errorMonitor

Usage in Deno

import { EventEmitter } from "node:events";

This symbol shall be used to install a listener for only monitoring 'error'events. Listeners installed using this symbol are called before the regular'error' listeners are called.

Installing a listener using this symbol does not change the behavior once an'error' event is emitted. Therefore, the process will still crash if no regular 'error' listener is installed.

Type

unique symbol
