Returns a Promise wrapped version of the supplied function or module.Callback-style function or module whose methods you want to promisify.

•    Javascript

Bluebird is a fully featured promise library with focus on innovative features and performance.

micro - Asynchronous HTTP microservices

•    Javascript

Important: Micro is only meant to be used in production. In development, you should use micro-dev, which provides you with a tool belt specifically tailored for developing microservices.

Hydra - Lightweight full-featured Promises, Async & Await Library in Swift

•    Swift

A more detailed look at how Hydra works can be found in ARCHITECTURE file or on Medium.

ecmascript-asyncawait - Async/await for ECMAScript

•    HTML

The introduction of Promises and Generators in ECMAScript presents an opportunity to dramatically improve the language-level model for writing asynchronous code in ECMAScript. The spec text can be found here. This proposal is implemented in a regenerator which can compile ES5 code containing async and await down to vanilla ES5 to run in existing browsers and runtimes.

coobjc - coobjc provides coroutine support for Objective-C and Swift

•    Objective-C

This library provides coroutine support for Objective-C and Swift. We added await method、generator and actor model like C#、Javascript and Kotlin. For convenience, we added coroutine categories for some Foundation and UIKit API in cokit framework like NSFileManager, JSON, NSData, UIImage etc. We also add tuple support in coobjc. Sequence of simple operations is unnaturally composed in the nested blocks. This "Callback hell" makes it difficult to keep track of code that is running, and the stack of closures leads to many second order effects.

AsyncEx - A helper library for async/await.

•    CSharp

A helper library for async/await. Note: This README is for AsyncEx v5 (prerelease). For AsyncEx v4 (the current version), see here. If you are seeing an upgrade error when upgrading from v3 to v4, see this documentation.

kneden - Transpile ES2017 async/await to vanilla ES6 Promise chains: a Babel plugin

•    Javascript

This project is currently unmaintained. If you want to take over, feel free to fork the repo. If such a fork gets maintained or contains useful improvements, I'd be willing to merge back and give repo+npm access.WARNING: Kneden is usable, but it's also not complete yet.

p-progress - Create a promise that reports progress

•    Javascript

Useful for reporting progress to the user during long-running async operations.Same as the Promise constructor, but with an appended progress parameter in executor.

FluentLenium - FluentLenium is a website automation framework which extends Selenium to write reliable and resilient UI functional tests

•    Java

FluentLenium makes the writing of acceptance testing more easy and in a fluent way using the power of css selectors. Build upon Selenium WebDriver. goTo("http://www.bing.com"); $("#sb_form_q").fill().with("FluentLenium"); $("#sb_form_go").submit(); assertThat(title()).contains("FluentLenium");

micro-router - :station: A tiny and functional router for Zeit's Micro

•    Javascript

A simple url pattern that you can define your path. In this path, you can set your parameters using a : notation. The req parameter from handler will return these parameters as an object. For more information about how you can define your path, see url-pattern that's the package that we're using to match paths.

posterus - Composable async primitives (futures) with cancelation, control over scheduling, and coroutines

•    Javascript

Posterus is a library of promise-like asynchronous primitives (futures) that support cancelation. Futures compose just like promises, but can also be cleanly shut down, aborting pending operations and freeing resources. Posterus also exposes its inner scheduling capabilities, allowing you to "opt out" of asynchrony when needed (motivating example).

awaiting - The async/await utility for browsers and Node.js.

•    Javascript

The async/await utility for browsers and Node.js. import whatever you want, you hipster.

async-to-gen - ⌛ Use async functions in your JavaScript today with speed and simplicity.

•    Javascript

Transform async functions to generator functions with speed and simplicity.

emittery - Simple and modern async event emitter

•    Javascript

It's only ~200 bytes minified and gzipped. I'm not fanatic about keeping the size at this level though.Emitting events asynchronously is important for production code where you want the least amount of synchronous operations.

AwaitKit - The ES8 Async/Await control flow for Swift

•    Swift

AwaitKit is a powerful Swift library inspired by the Async/Await specification in ES8 (ECMAScript 2017) which provides a powerful way to write asynchronous code in a sequential manner. Internally it uses PromiseKit to create and manage promises.

async - Easily run code asynchronously

•    PHP

This library provides a small and easy wrapper around PHP's PCNTL extension. It allows running of different processes in parallel, with an easy-to-use API. When creating asynchronous processes, you'll get an instance of ParallelProcess returned. You can add the following event hooks on a process.

async-reactor - Render async Stateless Functional Components in React

•    Javascript

The returned value is a regular Component. This examples are exporting a regular React component. You can integrate it into an existing application or render it on the page.

YieldAwait : Await Events with "yield"

•    DotNet

This is a .NET library that allows you to stop running the code wherever you want in order to await an event using the functionality of "yield" sentence. It's useful when you want to await asynchronous events or when you have to deal with many events in a sequential way.

Enough AsyncLock

Helper class for locking accross one or several await calls. Based on code developed and described by Stephen Toub, http://blogs.msdn.com/b/pfxteam/archive/2012
