A way to wait indefinitely until a job is completed

Hi, this is such an amazing project, thank you!

I wanted to know if there was a way to wait indefinitely until a job is completed before moving to the next in queue? Currently just setting it to a really large number does the job, but it just seems there is probably a better way that I'm missing.

I need this because I use this to write to a file on any state change, and it can result in overwriting issues sometimes if multiple file saves are called at the same time.

Again thank you for an amazing project!

RangeError: Too many elements passed to Promise.all

Your readme excited me because it says, I use it with tens of thousands of jobs on the queue. However, I tried adding 10,400 items to the queue and got RangeError: Too many elements passed to Promise.all. I am using the 1.2 syntax (second example in your README). Is there a different approach required for larger queues?

Nice work!

Not an issue. Just wanted to say thanks. This is a really great algorithm you've published here! Exactly what I needed and it worked right out of the box.

Doc issue

Thank you for this package.
The example code "running sequentially" seems incomplete to me. Could you take a look ?
Thanks !

Q/A is there a way to remove a currently waiting task after adding to queue?

Hi! This project looks super promising for my needs, and I love the minimum dependencies, but I have a feeling it's missing 1 crucial piece

The project I'm working on right now allows for users to request a batch of PDFs, package them up into a zip, and get later for download

I can make great use of this package to simplify the very asynchronous nature of this workflow on our server, but I don't see anything about removing a waiting request in the queue

say I have a queue with 10 requests, which won't resolve in an hour or so and decide 10 minutes after making my request I don't actually want that export anymore so I send another request to cancel my last request

wait() and end() make use of a hash to keep track of a request in the queue. Could this hash be used to remove that request from the queue later, assuming it's not currently executing?

Incorrect typings for the QueueStats interface

It looks like the type definition for QueueStats interface is incorrect.

index.d.ts contains the following definition:

export interface QueueStats {running: {number}, waiting: {number}, last: {number}}

this type means that the running, waiting and last property are all objects with a property inside them called number and a type of any. However looking at the code I think each of those should simply be of type number, like so:

export interface QueueStats {
    running: number;
    waiting: number;
    last: number;
}

TypeError: Queue is not a constructor

while using v2.1.4

const {Queue} = require('async-await-queue');
const myq = new Queue(1, 100);

TypeError: Queue is not a constructor

"typescript": "~4.9.5"
Works with v1.2.1

saw diff in index.d.ts
in 2.1.4 export declare class Queue .... is used
in 1.2.1 export class Queue ... is used
saw Andre Pena's answer. He thinks its of no use
