TypeError: Semaphore is not a constructor

[adam-nielsen]

Is there a trick to using this module in a Typescript project?

import Semaphore from 'semaphore-async-await';
const lock = new Semaphore(1);

TypeError: Semaphore is not a constructor

I was able to work around the issue by changing the import statement to this, but it seems a bit dodgy:

import SemaphoreModule from 'semaphore-async-await';
// Not sure why we need to do it this way...
const Semaphore = (SemaphoreModule as any)['default'];

const lock = new Semaphore(1); // works now

Am I doing something wrong?

Can you attach some playground or zipped example?

Here's an example: example.zip

Run it via:

npm install
npx ts-node index.ts

It looks like the issue is around module handling. If my code isn't a module then it seems to work, but once I configure it to work as a module that's when it seems to dislike the Semaphore constructor.

I'm getting the same error.
