A uniform cache interface for Redis and memcached that works out of the box, with Promises!

Usage no npm install needed!

<script type="module">
  import nodeEasyCache from '';



A cache abstraction for Node.js that supports both Redis and memcached using async/await (Javascript Promises). No plugins or configuration needed - supports Redis and memcached out of the box!

Use case:

  • for developers to easily get started with Redis or memcached
  • for developers to easily switch between Redis and memcached
  • for developers to use Redis and memcached in the same codebase

Inspired by Shopify's go-cache

Uses redis and memjs under the hood

Test cases written with Jest and continuous integration with Docker, Docker Compose and Circle CI

Get started

  1. npm install node-easy-cache

  2. Check out the Example Project

Supported operations

All operations run the exact same on on Redis and memcached clients. Supported operations:

Function Return type (if not void)
client.get(key) string or null if missed
client.set(key, value, _ttl)
client.delete(key) boolean
client.increment(key, delta) Number
client.decrement(key, delta) Number

Note on integer behaviour in Redis vs memcached

Memcached does not allow storing negative integers, so the increment and decrement behaviour between Redis and memcached is different. However, this API makes them behave the same by using get and set operations for memcached using strings. Therefore, using increment and decrement for memcached is slower, but it will have the same behaviour as Redis.

If you want to use the default memcached behaviour, you can access the underlying client by accessing client.memcachedClient


Before testing, MAKE SURE THAT YOU HAVE NO IMPORTANT DATA IN REDIS/MEMCACHE! The test cases flush the database frequently.

  1. Make sure you have redis-server running and memcached running. If you have Docker installed, you can run docker-compose up to run Dockerized containers for testing

  2. If you're not running Redis or memcached locally on the default port, set the REDIS_CONNECTION or MEMCACHED_CONNECTION environment variable

  3. Run npm test


Please report any bugs using the GitHub issue tracker.

If you want to contribute features, please add test cases and run prettier --write . (code formatter) before submitting. Notice that the test cases for both Redis and memcached should be the exact same. You can run the script to ensure this.
