promiseHooks.onInit(init)

• init <Function> The init callback to call when a promise is created.
• Returns: <Function> Call to stop the hook.

The init hook must be a plain function. Providing an async function will throw as it would produce an infinite microtask loop.

import { promiseHooks } from 'node:v8';

const stop = promiseHooks.onInit((promise, parent) => {});const { promiseHooks } = require('node:v8');

const stop = promiseHooks.onInit((promise, parent) => {});
