Concurrency Packages

A time-based rate limiter using promises

A library of latches suitable for managing concurrent code.

Estimate the number of processes that can be executed concurrently

Tiny scheduler for functions returning promises that can limit their concurrency.

Iterate over promises, promise-returning or async/await functions in series or parallel. Support settle (fail-fast), concurrency (limiting) and hooks system (start, beforeEach, afterEach, finish)

Limit the number of asynchronous concurrent tasks running

resolves promises to an err, data tuple

Persistent Shared Memory and Parallel Programming Model

Read/Write lock on asynchronous code

A nice, lightweight module that limits concurrency of a function. If you're looking to say 'I want 3 instances of this to run at a time', then this module is for you.

Add some concurrency to a writable stream

a queue runner with priorities, concurrency and promises

Leader and followers algorithm to make partitioning easy.

Perhaps the most awesome way of interacting with data using a chainable API

Userful promise utils, include map, filter, retry and sleep

run promises in parallel with a concurrency limit
