Awesome

Aigle is an ideal promise library which is faster and more efficient than other libraries. On top of being an impressive benchmark exercise, it is a production-ready library that implements the Promise A+ standard.

Also it has a lot of async style functions, you can start using Promise easily.

Usage

Node.js

npm install --save aigle

const Aigle = require('aigle');

const each = require('aigle/each');

TypeScript

import Aigle from 'aigle';

import { Aigle } from 'aigle';

Async/Await

global.Promise = Aigle;

async function getUsers(ids) {
  const users = await Promise.map(ids, getUser);
  const targets = await Promise.filter(users, filterUser);
  return targets;
}

async function getUsers(ids) {
  return await Promise.map(ids, getUser).filter(filterUser);
}

Convert synchronous functions to asynchronous functions

Aigle.mixin(require('lodash'));

return Aigle.map([1.1, 1.4, 2.2], (n) => Aigle.delay(10, n * 2)) // [2.2, 2.8, 4.4]
  .uniqBy((n) => Aigle.delay(10, Math.floor(n))) // [2.2, 4.4]
  .sum() // 6.6
  .times() // [0, 1, 2, 3, 4, 5];
  .then((value) => console.log(value)); // [0, 1, 2, 3, 4, 5];

browser

Recommend to use webpack, browserify, Rollup or any bundling tool.

or prebuilt scripts from here.

This will expose to global as window.Promise.

<script src="dist/aigle.min.js"></script>

window.Promise;
