Which should you use? A side-by-side look at what each one does, who it suits, what it costs, how hard it is to set up, and where each falls short.
Open source · MIT
A Node.js client for Redis, written in TypeScript, with Cluster, Sentinel, and Streams support.
Open source · MIT
A Redis client library for Node.js, written in TypeScript, for talking to Redis from JavaScript code.
The short answer
Choose ioredis if you need…
- 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
Choose node-redis if you need…
- Node.js developers who need to read and write Redis data from an application
- Teams building caching or session storage on top of Redis
- Projects that want optional Redis modules such as JSON, search, or time-series through add-on packages
- Developers who need to connect to Redis clusters, TLS, or UNIX sockets

What each one is
ioredis
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.
node-redis
node-redis is a client library that lets Node.js programs connect to a Redis server and run its commands, such as storing and reading keys. Redis is a data store often used for caching and fast temporary data. The library exposes Redis commands in both their raw names and camel-cased JavaScript versions, and supports transactions, pub/sub, and connections to clusters.
Best for
ioredis
- 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
node-redis
- Node.js developers who need to read and write Redis data from an application
- Teams building caching or session storage on top of Redis
- Projects that want optional Redis modules such as JSON, search, or time-series through add-on packages
- Developers who need to connect to Redis clusters, TLS, or UNIX sockets
Strengths
ioredis
- 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
node-redis
- Supports all standard Redis commands, with a fallback sendCommand method for anything not yet wrapped
- Offers both raw and camel-cased command names, plus typed reply transformation
- Installs as one package, with separate packages available if you need only part of it
Not ideal for
ioredis
- 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
node-redis
- People who want a graphical Redis admin tool; this is code, not an app with a UI
- Projects that need an object-mapping layer; the README points to redis-om-node for that
- Anyone without a running Redis server, since the library needs one to connect to
Trade-offs
ioredis
- 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
node-redis
- Requires a running Redis server; the library alone does nothing without one
- The README notes some API differences in cluster mode and a pitfall with spreading arguments into commands like hDel, so careful reading is needed
- Version 5 and 6 changes, such as the pool API, mean older examples may not match the current version
