OnExit

Exit event listeners for Deno. Listens for unload and unhandledrejection events.

Basic Usage

import { addExitListener } from "<import-path>";

addExitListener(event => console.debug(`Process exit detected\nCause: ${event?.cause}`));

Signals

By default, the exit event will not be dispatched when the process exits due to a signal (e.g. SIGINT, SIGTERM, SIGKILL, etc.). To enable this behavior, call the exitOnSignal function with the signals you want to listen for.

/**
 * Registers exit event listeners for the specified signals.
 *
 * @param {Deno.Signal[]} [signals=["SIGINT", "SIGTERM", "SIGQUIT"]] - The signals to listen for.
 * @param {boolean} [clear=true] - Whether to clear any previously registered signal listeners.
 */

import { exitOnSignal } from "<import-path>";

exitOnSignal(["SIGINT"]); // defaults to SIGINT, SIGTERM, SIGQUIT

Signal listeners can also be cleared by calling clearSignalListeners.
