promiseHooks.createHook(callbacks)


    注册要为每个 promise 的不同生命周期事件调用的函数。

    The hook callbacks must be plain functions. Providing async functions will throw as it would produce an infinite microtask loop.

    Registers functions to be called for different lifetime events of each promise.

    The callbacks init()/before()/after()/settled() are called for the respective events during a promise's lifetime.

    All callbacks are optional. For example, if only promise creation needs to be tracked, then only the init callback needs to be passed. The specifics of all functions that can be passed to callbacks is in the Hook Callbacks section.

    import { promiseHooks } from 'node:v8';
    
    const stopAll = promiseHooks.createHook({
      init(promise, parent) {}
    });const { promiseHooks } = require('node:v8');
    
    const stopAll = promiseHooks.createHook({
      init(promise, parent) {}
    });
