Must use import to load ES Module

[stwonary]

I'm using the sample code and got this error:

import pThrottle from 'p-throttle';

const now = Date.now();

const throttle = pThrottle({
	limit: 2,
	interval: 1000
});

Must use import to load ES Module: /var/task/node_modules/p-throttle/index.js require() of ES modules is not supported. require() of /var/task/node_modules/p-throttle/index.js from /var/task/app.js is an ES module file as it is a .js file whose nearest parent package.json contains "type": "module" which defines all .js files in that package scope as ES modules. Instead rename index.js to end in .cjs, change the requiring code to use import(), or remove "type": "module" from /var/task/node_modules/p-throttle/package.json.

just found this article

https://gist.github.com/sindresorhus/a39789f98801d908bbc7ff3ecc99d99c

but I have no idea how this "type": "module" gonna impact any legacy codes. any ideas?
I use Typescript and on some old dependency I still use require('keyword-extractor')

Then I would recommend importing this package using await import(…) which does work in CommonJS.

@sindresorhus even with dynamic imports it produces an ERR_REQUIRE_ESM error.
Tried Node 16 and 18.

const { default: pThrottle } = await import('p-throttle');

Any tip?

Seems to be working here in Node 18.18.0 with something like this;

const setupThrottling = async ({ limit, interval }) => {
  const { default: pThrottle } = await import('p-throttle');

  const throttle = pThrottle({
    limit,
    interval,
  });

  const throttled = throttle(async (callback) => callback());

  return throttled;
};

const useThrottling = await setupThrottling({ limit: 1, interval: 2000 });

useThrottling(() => somethingThrottled());
