async-easy-group v1.0.2

async-easy-group

Group asynchronous requests together in loops and elsewhere and resolve the group after all the members have resolved

Get Started

Install with npm for use with node/webpack, or serve ./build/async-easy-group.js to the client for use on the front end

npm i -S async-easy-group

Simple to use

Add your callback to the group, then call the done method (wait.done in this case) when your asynchronous operations resolve

const wait = asyncGroup(10)
  .then(() => {
    console.log('Asynchronous calls finished');
  });

Extra options

Add in a timeout length (3000 here) and call the start method prior to initializing your asynchronous calls in order to call the catch callback if your asynchronous operations fail to resolve in time

Also add in an index when you call the done method in order to seamlessly switch to using the results of each call in an array, rather than using the results provided by the final operation to resolve

const asyncGroup = require('async-easy-group');

const wait = asyncGroup(10, 3000)
  .then((data) => {
    console.log('Data retrieved:', data);
  })
  .catch((partialData) => {
    console.error('Partial data retrieved:', partialData);
  });

const func = index => (() => {
  wait.done('some data', index);
});

wait.start();
for (let i = 0; i < 10; i++) {
  setTimeout(func(i), 1000);
}
