What it is

ioredis is a Redis client library for Node.js. It lets your JavaScript or TypeScript code send commands to a Redis server and read the results, using either callbacks or promises. It also covers Redis Cluster, Sentinel, Pub/Sub, Lua scripting, and TLS connections.

  • Store and read cached values with simple get and set calls
  • Publish messages to channels and subscribe to them with Pub/Sub
  • Process event data with Redis Streams
  • Run Lua scripts or Redis Functions from Node.js code
  • Connect to a Redis Cluster or Sentinel setup with a single client API

Great for

  • Node.js backend developers who already run Redis and want a full-featured client
  • Teams maintaining existing projects that already depend on ioredis
  • Apps that use Redis Cluster or Sentinel for high availability
  • TypeScript projects that want built-in type declarations

Not ideal for

  • New projects: the README says node-redis is the recommended client for new projects and that ioredis is in best-effort maintenance
  • Projects that need Redis Stack features like search or JSON as a first-class API, since the README points to node-redis for those
  • Non-Node.js environments, since this is a Node.js client

How to get it

  1. 1

    Install with a package manager

    You'll need: Node.js 20 or newer (for v6, per the README version table) · A running Redis server (the default connection is localhost:6379)

    Install the library

    npm install ioredis

    Optional: add Node.js type declarations in a TypeScript project

    npm install --save-dev @types/node
  2. 2

    Run it

    • Install the package with npm install ioredis.
    • Create a client with const Redis = require("ioredis") and const redis = new Redis().
    • Call a command such as redis.set("mykey", "value") and read it back with redis.get("mykey").
    • Pass connection options or a redis:// URL to the constructor if your server is not on localhost:6379.
  3. 3

    Get the most out of it

    • Use a redis:// or rediss:// connection string, with rediss:// for TLS, to configure connections in one line
    • Use the Cluster and Sentinel classes when you run a high-availability Redis setup
    • Define custom commands through the Lua scripting abstraction
    • Use the examples/ folder in the repository for working code on hashes, lists, sets, sorted sets, and streams

Strengths

  • Covers a wide range of Redis features, including Cluster, Sentinel, Streams, and TLS
  • Ships with official TypeScript declarations and is written in TypeScript
  • Supports both Node callbacks and native promises

Trade-offs

  • The README says ioredis is in best-effort maintenance and recommends node-redis for new projects
  • Requires Node.js 20 or newer for the current v6 release, according to the version table
