asyncHook.enable()
- 返回: <AsyncHook>
asyncHook
的引用。
启用给定 AsyncHook
实例的回调。
如果没有提供回调,则启用是无操作的。
默认禁用 AsyncHook
实例。
如果 AsyncHook
实例应该在创建后立即启用,则可以使用以下模式。
import { createHook } from 'node:async_hooks';
const hook = createHook(callbacks).enable();
const async_hooks = require('node:async_hooks');
const hook = async_hooks.createHook(callbacks).enable();
- Returns: <AsyncHook> A reference to
asyncHook
.
Enable the callbacks for a given AsyncHook
instance. If no callbacks are
provided, enabling is a no-op.
The AsyncHook
instance is disabled by default. If the AsyncHook
instance
should be enabled immediately after creation, the following pattern can be used.
import { createHook } from 'node:async_hooks';
const hook = createHook(callbacks).enable();
const async_hooks = require('node:async_hooks');
const hook = async_hooks.createHook(callbacks).enable();
