Promisify a callback-style function

Compose promise-returning & async functions into a reusable pipeline

Beautiful concurrency for JavaScript

Limit the execution rate of a function

Async is a JavaScript asynchronous flow library designed to manage the execution and coordination of asynchronous tasks in Node.js and the browser. It provides functional utilities to wrap, process, and orchestrate complex asynchronous workflows. The library distinguishes itself through a comprehensive task orchestrator that handles dependency graphs to resolve circular references and manages concurrent task queues. It includes a unification bridge that allows callback-style and promise-based functions to operate within the same execution interface. The project covers several primary capabil

RxJS is a library for reactive programming that provides a framework for composing asynchronous and event-based programs. It utilizes observable sequences to model data flows, allowing developers to manage complex sequences of events through a declarative programming interface. The library implements the observer pattern to facilitate decoupled communication between data producers and subscribers. By employing a lazy execution model, streams remain dormant until a consumer explicitly subscribes, at which point data production is triggered. This approach enables the construction of predictable

promise semaphore

Filter promises concurrently

Promises fail silently if you don't attach a .catch() handler.

Bluebird is a JavaScript promise library designed for managing asynchronous operations with a custom promise implementation. It provides a framework for controlling promise lifecycles and orchestrating non-blocking programming patterns. The library distinguishes itself with an asynchronous debugging toolkit that captures long stack traces across asynchronous boundaries and a global handler for unhandled promise rejections. It includes a predicate-based error filtering system to target specific exception types and a mechanism for the deterministic cleanup of system resources. It covers a broa

Modernize node.js to current ECMAScript specifications! node.js will not update their API to ES6+ for a while. This library is a wrapper for various aspects of node.js' API.
