@olan88/Q

A small TypeScript promise queue package that works in both ESM and CommonJS.

Install

npm install @olan88/Q

Usage

ESM

import { Q } from "@olan88/Q";

const queue = new Q();

queue.add(async () => {
  // runs first
});

queue.add(async () => {
  // runs after previous task is finished
});

await queue.onIdle();

CommonJS

const { Q } = require("@olan88/Q");

const queue = new Q();
queue.add(() => Promise.resolve("ok"));

API

• new Q()
• queue.add(job)
  • Accepts a function (() => value | Promise) so the queue controls when it starts.
  • Returns a promise for the task result.
• queue.size
  • Number of queued/running tasks.
• queue.onIdle()
  • Resolves when all currently queued tasks are done.
