# Connect with @upstash/redis

[@upstash/redis](https://github.com/upstash/redis-js)
is an HTTP/REST based Redis client built on top of
[Upstash REST API](/redis/features/restapi). For more information,
refer to the documentation of Upstash redis client ([TypeScript](/redis/sdks/ts/overview) & [Python](/redis/sdks/py/overview)).

It is the only connectionless (HTTP based) Redis client and designed for:

* Serverless functions (AWS Lambda)
* Cloudflare Workers (see
  [the example](https://github.com/upstash/redis-js/tree/main/examples/cloudflare-workers-with-typescript))
* Fastly Compute\@Edge (see
  [the example](https://github.com/upstash/upstash-redis/tree/master/examples/fastly))
* Next.js (see [the quickstart](/redis/quickstarts/nextjs-app-router)), Jamstack
* Client side web/mobile applications
* WebAssembly
* and other environments where HTTP is preferred over TCP.

See
[the list of APIs](https://upstash.com/docs/redis/features/restapi#rest-redis-api-compatibility)
supported.

## Quick Start

### Install

```bash theme={"system"}
npm install @upstash/redis
```

### Usage

```typescript theme={"system"}
import { Redis } from "@upstash/redis";

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

const data = await redis.get("key");
console.log(data);
```

<Tip>
  You can find values to set as `UPSTASH_REDIS_REST_URL` and`UPSTASH_REDIS_REST_TOKEN`
  on the details tab of your database on [Upstash Console](https://console.upstash.com/redis).
  See [Connect Client page](/redis/howto/connect-client#database) for more information.
</Tip>

If you define `UPSTASH_REDIS_REST_URL` and`UPSTASH_REDIS_REST_TOKEN` environment
variables, you can load them automatically.

```typescript theme={"system"}
import { Redis } from "@upstash/redis";

const redis = Redis.fromEnv();

const data = await redis.get("key");
console.log(data);
```
