@scaleforge/async-group

AsyncGroup simplifies promise management and ensures proper shutdown synchronization in NodeJS. It allows for storing promises in a shared context and conveniently wait for their settlement. AsyncGroup is ideal for background operations and ensuring completion before application shutdown.

Installation

npm install --save @scaleforge/async-group

Usage

import AsyncGroup from '@scaleforge/async-group';

const group = new AsyncGroup();

async function asyncOperation() {
  await new Promise((resolve) {
    setTimeout(() => resolve(), Math.floor(Math.random() * 60000 ));
  })
}

async function onApplicationBootstrap() {
  group.add(asyncOperation());
  group.add(asyncOperation());
  group.add(asyncOperation());
}

async function onApplicationShutdown() {
  await group.wait();
}
