Upstash works with Redis® API, that means you can use any Redis client with Upstash. At the Redis Clients page you can find the list of Redis clients in different languages.

Probably, the easiest way to connect to your database is to use redis-cli. Because it is already covered in Getting Started, we will skip it here.

​
Database

After completing the getting started guide, you will see the database page as below:

The information required for Redis clients is displayed here as Endpoint, Port and Password. Also when you click on Connect button, you can copy the code that is required for your client.

Below, we will provide examples from popular Redis clients, but the information above should help you configure all Redis clients similarly.

If you have enabled TLS in your database, please refer to Connect With TLS section instead.

upstash-redis

Because upstash-redis is HTTP based, we recommend it for Serverless functions. Other TCP based clients can cause connection problems in highly concurrent use cases.

Library: upstash-redis

Example:

import { Redis } from "@upstash/redis";

const redis = new Redis({
  url: "UPSTASH_REDIS_REST_URL",
  token: "UPSTASH_REDIS_REST_TOKEN",
});

(async () => {
  try {
    const data = await redis.get("key");
    console.log(data);
  } catch (error) {
    console.error(error);
  }
})();

​
Node.js

Library: ioredis

Example:

const Redis = require("ioredis");

let client = new Redis("redis://:YOUR_PASSWORD@YOUR_ENDPOINT:YOUR_PORT");
await client.set("foo", "bar");
let x = await client.get("foo");
console.log(x);

​
Python

Library: redis-py

Example:

import redis
r = redis.Redis(
host= 'YOUR_ENDPOINT',
port= 'YOUR_PORT',
password= 'YOUR_PASSWORD')
r.set('foo','bar')
print(r.get('foo'))

​
Java

Library: jedis

Example:

Jedis jedis = new Jedis("YOUR_ENDPOINT", "YOUR_PORT");
jedis.auth("YOUR_PASSWORD");
jedis.set("foo", "bar");
String value = jedis.get("foo");
System.out.println(value);

​
Go

Library: redigo

Example:

func main() {
  c, err := redis.Dial("tcp", "YOUR_ENDPOINT:YOUR_PORT")
  if err != nil {
      panic(err)
  }

  _, err = c.Do("AUTH", "YOUR_PASSWORD")
  if err != nil {
      panic(err)
  }

  _, err = c.Do("SET", "foo", "bar")
  if err != nil {
      panic(err)
  }

  value, err := redis.String(c.Do("GET", "foo"))
  if err != nil {
      panic(err)
  }

  println(value)
}
