A reimplementation of Node's util.getPromiseDetails(), which was removed in v16.

Note

This package is not recommended for use in production other than for reflection purposes. For more information about this topic, please see nodejs/node#40054.

npm i inspect-promise

Usage

There are two ways you can use this package:

1. Import normally as a function

import { inspectPromise } from "inspect-promise";

const p = Promise.resolve(100);

console.log(inspectPromise(p));

2. Globally modify the Promise constructor

import "inspect-promise/extend";

const p = Promise.resolve(100);

console.log(Promise.inspect(p));

Both result in the same output:

{
  status: "fulfilled",
  value: 100
}
