#Introduction

Redis is an open source, in-memory, key-value data store most commonly used as a primary database, cache, message broker, and queue. Redis cache delivers sub-millisecond response times, enabling fast and powerful real-time applications in industries such as gaming, fintech, ad-tech, social media, healthcare, and IoT.

Redis is a great database for use with Node. Both Redis and Node share similar type conventions and threading models, which makes for a very predictable development experience. By pairing Node and Redis together you can achieve a scalable and productive development platform.

Redis has two primary Node clients which are node-redis and ioredis. Both are available through npm. We generally suggest using node-redis, as it has wide support for Redis modules, is easily extended, and is widely used.

Check out a list of Redis clients that the community has built for Node.

This article shows how to get started with the recommended libraries: node-redis and ioredis.

#node-redis

#Step 1. Run a Redis server

Follow the instructions in the Redis quick start to get setup with Redis. The rest of this tutorial expects you to have Redis setup and ready to use. You will need the connection string.

#Step 2. Install node-redis using NPM or Yarn

Run the following NPM command to install the Redis client.

#Step 3. Write your application code

Use the following sample code for our Node.js application:

#ioredis

#Step 1. Install `ioredis` using `npm` (or `yarn`)

#Step 2. Write your Application Code
