Node.js Redis Integration Guide

Using Redis

Node.js Redis integration uses ioredis for caching and sessions.

Introduction to Redis and Node.js

Redis is an in-memory data structure store, commonly used as a database, cache, and message broker. It supports data structures such as strings, hashes, lists, sets, and more. When integrated with Node.js, Redis can significantly enhance the performance of applications by providing fast access to cached data and maintaining session information across distributed systems.

First, ensure you have Node.js and npm installed, then run the following command to install ioredis:

Connecting to a Redis Instance

After installing ioredis, you can connect to a Redis server by creating a new instance of Redis. By default, ioredis connects to localhost:6379, but you can specify a different host and port if needed.
