co - The ultimate generator based flow-control goodness for nodejs (supports thunks, promises, etc)

---

Generator based control flow goodness for nodejs and the browser, using promises, letting you write non-blocking code in a nice-ish way.co@4.0.0 has been released, which now relies on promises. It is a stepping stone towards the async/await proposal. The primary API change is how co() is invoked. Before, co returned a "thunk", which you then called with a callback and optional arguments. Now, co() returns a promise.

I intend to use this space to document my promise modules, useful promise patterns, and how to solve common problems. For now though, you can see all my promise modules below.Star this repo to show your interest, so I can know whether to prioritize this work.

chai-as-promised - Extends Chai with assertions about promises.

---

Chai as Promised extends Chai with a fluent language for asserting facts about promises. Notice: either return or notify(done) must be used with promise assertions. This can be a slight departure from the existing format of assertions being used on a project or by a team. Those other assertions are likely synchronous and thus do not require special handling.

AwaitKit - The ES8 Async/Await control flow for 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.

p-progress - Create a promise that reports progress

---

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.

promises-tests - Compliances tests for Promises/A+

---

This suite tests compliance of a promise implementation with the Promises/A+ specification. Passing the tests in this repo means that you have a Promises/A+ compliant implementation of the then() method, and you can display the Promises/A+ logo in your README. You can also send a pull request to have your implementation listed on the implementations page.

promises - Promises/A+ library for PHP with synchronous support

---

Promises/A+ implementation that handles promise chaining and resolution iteratively, allowing for "infinite" promise chaining while keeping the stack size constant. Read this blog post for a general introduction to promises. A promise represents the eventual result of an asynchronous operation. The primary way of interacting with a promise is through its then method, which registers callbacks to receive either a promise's eventual value or the reason why the promise cannot be fulfilled.

---

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.
