Using p-queue with `require`

[fergiemcdowall]

My node project doesn't let me import modules. Is it possible to use p-queue with require? If so, what is the recommended incantation?

If anybody stumbles upon this later, the incantation for those forced to use require is ->

const queue = new (await import('p-queue')).default({concurrency: 1})

Thanks for the answer @fergiemcdowall, much appreciated!

Just in case if anyone wants to re-use the PQueue constructor instead of reusing the same long line of an importation:

let PQueue;
(async () => {
    PQueue = (await import('p-queue')).default;
})();

//... * anything *

const queue1 = new PQueue({concurrency: 5});

const queue2 = new PQueue({concurrency: 10});

@otanim yes, if you account for the possible race condition when you first assign PQueue, then thats a nice way to do it 👍

I got

const queue = new (await import('p-queue')).default({ concurrency: 1 });

That would be because OP used the await INSIDE an Async Closure. Your example appears to use the await AT TOP LEVEL, which doesn't work in any except possibly a beta version of Node.

If you don't know what Top Level, Async, Await and Closure actually mean you have a fair bit of studying to do before you'll be able to use this.
