process.finalization.unregister(ref)

• ref <Object> | <Function> 对先前注册的资源的引用。

  \ref <Object> | <Function> The reference to the resource that was registered previously.

此函数从最终注册表中删除对象的注册,因此将不再调用回调。

\This function remove the register of the object from the finalization registry, so the callback will not be called anymore.

const { finalization } = require('node:process');
// Please make sure that the function passed to finalization.register()
// does not create a closure around unnecessary objects.
function onFinalize(obj, event) {
 // You can do whatever you want with the object
 obj.dispose();
}
function setup() {
 // This object can be safely garbage collected,
 // and the resulting shutdown function will not be called.
 // There are no leaks.
 const myDisposableObject = {
 dispose() {
 // Free your resources synchronously
 },
 };
 finalization.register(myDisposableObject, onFinalize);
 // Do something
 myDisposableObject.dispose();
 finalization.unregister(myDisposableObject);
}
setup();import { finalization } from 'node:process';
