p-waterfall - Run promise-returning & async functions in series, each passing its result to the next

  •        7

Returns a Promise that is fulfilled when all promises returned from calling the functions in tasks are fulfilled, or rejects if any of the promises reject. The fulfilled value is the value returned from the last task.Functions are expected to return a value. If a Promise is returned, it's awaited before continuing with the next task.

node-promise-mysql


Promise-mysql is a wrapper for mysqljs/mysql that wraps function calls with Bluebird promises. Usually this would be done with Bluebird's .promisifyAll() method, but mysqljs/mysql's footprint is different to that of what Bluebird expects. At the minute only the standard connection (using .createConnection()) and the pool (using .createPool()) is supported. createPoolCluster is not implemented yet.

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.


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.

IxJS - The Interactive Extensions for JavaScript


The Interactive Extensions for JavaScript (IxJS) brings the Array#extras combinators to iterables, generators, async iterables and async generators. With the introduction of the Symbol.iterator and generators in ES2015, and subsequent introduction of Symbol.asyncIterator and async generators, it became obvious we need an abstraction over these data structures for composition, querying and more.IxJS unifies both synchronous and asynchronous pull-based collections, just as RxJS unified the world of push-based collections. RxJS is great for event-based workflows where the data can be pushed at the rate of the producer, however, IxJS is great at I/O operations where you as the consumer can pull the data when you are ready.

promise-fun - Promise packages, patterns, chat, and tutorials


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.

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


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.

proposal-async-iteration - Asynchronous iteration for JavaScript


The iterator interface (introduced in ECMAScript 2015) is a sequential data access protocol which enables the development of generic and composable data consumers and transformers. Their primary interface is a next() method which returns a { value, done } tuple, where done is a boolean indicating whether the end of the iterator has been reached, and value is the yielded value in the sequence. Since both the next value in the sequence and the "done" state of the data source must be known at the time that the iterator method returns, iterators are only suitable for representing synchronous data sources. While many data sources encountered by the JavaScript programmer are synchronous (such as in-memory lists and other data structures), many others are not. For instance, any data source which requires I/O access will be typically represented using an event-based or streaming asynchronous API. Unfortunately, iterators cannot be used to represent such data sources.

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.

ea-async - EA Async implements async-await methods in the JVM.


EA Async implements async-await methods in the JVM. It allows programmers to write asynchronous code in a sequential fashion.

chillout - Reduce CPU usage in JavaScript


Reduce JavaScript CPU usage by asynchronous iteration. Provides asynchronous iteration functions that have a Promise based interface and it can execute with low CPU usage. Each iteration adds delay if the processing is heavy to maintain the CPU stability. Iterate without delay if processing is fast. Therefore, it will realize friendly processing for your machine. It can execute JavaScript without "Warning: Unresponsive Script" alert in the browser.

ecmascript-asyncawait - Async/await for ECMAScript


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.
