Install

npm i @mkhl_ivnv/promise-queue

Import

Use the ESM imports

import { PromiseQueue } from "@mkhl_ivnv/promise-queue";

Usage

Create new instance of PromiseQueue and be shure specify concurrency on constructor >= 1

import { PromiseQueue } from "@mkhl_ivnv/promise-queue";

const queue = new PromiseQueue({ concurrency: 1 });

Use the public method enqueue to add new task on queue. This method returned new promise that includes queue waiting time and task execution time.

import { PromiseQueue } from "@mkhl_ivnv/promise-queue";

const queue = new PromiseQueue({ concurrency: 1 });

const task = () => fetch('https://fetch.example');
const taskOnQueue = queue.enqueue(task);

taskOnQueue.then((fetchResponse) => fetchResponce.json());

You can use AbortController to reject task promise.

import { PromiseQueue } from "@mkhl_ivnv/promise-queue";

const queue = new PromiseQueue({ concurrency: 1 });
const abortController = new AbortController();
const { signal, abort } = abortController;

const task = () => fetch('https://fetch.example', {signal});
const taskOnQueue = queue.enqueue(task, signal);

abort();

taskOnQueue.then((fetchResponse) => fetchResponce.json());
