# then-queue a simple asynchronous queue [![Build Status](https://img.shields.io/travis/then/queue/master.svg)](https://travis-ci.org/then/queue) [![Dependency Status](https://img.shields.io/gemnasium/then/queue.svg)](https://gemnasium.com/then/queue) [![NPM version](https://img.shields.io/npm/v/then-queue.svg)](http://badge.fury.io/js/then-queue) ## Installation npm install then-queue ## API ### new Queue() ```js var Queue = require('then-queue'); var q = new Queue(); ``` A fresh queue! ### queue.push(item) Push an item onto the queue ### queue.pop() -> Promise Item Pop an item from the queue ### queue.length Amount of items in the queue (note that this can be negative if `pop` has been called more times than `push`). ### Events The `length-changed` event gets emitted whenever `pop` or `push` has been called. You could use it to spawn/kill workers when the length changes.
