Asynchronous Programming Library for JavaScript & Node.js

🌊 Let your code flow. Extension methods for fluent syntax in Swift.

Simplest way to manage asynchronicity

Makes websocket's API just like REST with Promise-like API, with native Promises.

A tiny library to wait for the results of multiple callbacks. For node and the browser.

Don't keep your promises 😉

Thenable contract

🙏 Promise A+ implementation

Simplest request promise wrapper with retry

Deferred (and comparison to Future and Promise)

Expirable Promises

Ergo is a Swift framework for concurrent programming based on promise pipelining. It could help to avoid callback hell in complex asynchronous task

Promise wrapper on top of fs module

Define and chain Closures with Inputs and Outputs

Make your module implement dual APIs, callback API and thenable (Promise) API.

JavaScript Native Contracts

Powerful event-based system that introduces thenable objects to enable promise-like event handling.

🦁 Step by step build a Promise Class & Promise/Promise A+

then-ref is a utility library designed to standardize the APIs of third-party libraries, providing consistent then, catch, and finally methods for both synchronous and asynchronous APIs.

Test whether an object looks like a promises-a+ promise.
