The fastest javascript implementation of a double-ended queue. Used by the official Redis, MongoDB, MariaDB & MySQL libraries for Node.js and many other libraries. Maintains compatability with deque.

Package Exports

  • denque
  • denque/index.js

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (denque) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Denque is a well tested, extremely fast and lightweight double-ended queue implementation with zero dependencies and includes TypeScript types.

Double-ended queues can also be used as a:

This implementation is currently the fastest available, even faster than double-ended-queue, see the benchmarks.

Every queue operation is done at a constant O(1) - including random access from .peekAt(index).

Works on all node versions >= v0.10

Quick Start

Install the package:

npm install denque

Create and consume a queue:

const Denque = require("denque");

const denque = new Denque([1,2,3,4]);
denque.shift(); // 1
denque.pop(); // 4

See the API reference documentation for more examples.
