node-redis VS Redis

To use Redis in Node.js, we need to install the redis package. It serves as a client to the Redis instance on our machine itself:

Ensure that you have Redis installed before trying out the sample code below. You may follow the official quickstart guide to learn how to get it up and running. Furthermore, make sure to install the necessary dependencies before running the program. This example utilizes the node-redis library.

To make data retrieval efficient and minimize the need to request data from the API on every page load, I implemented a caching strategy using the ioredis package, which is a popular redis client for Node.js for interacting with a Redis database.

These are the objects I pass to ioredis to create my Redis instances (one for sessions and one as the main one):

In order to try and mitigate the OOMs. I read the Background Jobs in Node.JS with Redis blog post and implemented Heroku Data For Redis with ioredis, BullMQ and Throng,

Redis.Redis and Redis.Cluster at the end of the rule actually refer to the ioredis constructors, so to set them up, we must use the ioredis constructors.

ioredis is a popular Node.js client, providing a robust support for Redis Cluster.

To connect to Redis from your application, you will need a library that can perform that for you (Otherwise you have to reinvent the wheel). While I've been using IORedis for a nodeJS application in this demo, if you have been using a different language, you will have to look for different connectors like Lettuce for Java or perhaps go-redis for Go.

The Redis client I'm going to use today is ioredis, because its API is intuitive, very robust and with good performance.

Just create your own wrapper service around one of the existing nodejs redis clients, I used the following client https://github.com/luin/ioredis
