# Deployment

We support various platforms, such as nodejs, cloudflare and fastly. Platforms
differ slightly when it comes to environment variables and their `fetch` api.
Please use the correct import when deploying to special platforms.

## Node.js / Browser

Examples: Vercel, Netlify, AWS Lambda

If you are running on nodejs you can set `UPSTASH_REDIS_REST_URL` and
`UPSTASH_REDIS_REST_TOKEN` as environment variable and create a redis instance
like this:

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

const redis = new Redis({
  url: <UPSTASH_REDIS_REST_URL>,
  token: <UPSTASH_REDIS_REST_TOKEN>,
})

// or load directly from env
const redis = Redis.fromEnv()
```

<Info>
  If you are running on nodejs v17 and earlier, `fetch` will not be natively
  supported. Platforms like Vercel, Netlify, Deno, Fastly etc. provide a polyfill
  for you. But if you are running on bare node, you need to either specify a
  polyfill yourself or change the import path slightly:

  ```typescript theme={"system"}
  import { Redis } from "@upstash/redis/with-fetch";
  ```
</Info>

* [Code example](https://github.com/upstash/upstash-redis/blob/main/examples/nodejs)

## Cloudflare Workers

Cloudflare handles environment variables differently than Node.js. Please add
`UPSTASH_REDIS_REST_URL` and `UPSTASH_REDIS_REST_TOKEN` using
`wrangler secret put ...` or in the cloudflare dashboard.

Afterwards you can create a redis instance:

```ts theme={"system"}
import { Redis } from "@upstash/redis/cloudflare"

const redis = new Redis({
  url: <UPSTASH_REDIS_REST_URL>,
  token: <UPSTASH_REDIS_REST_TOKEN>,
})


// or load directly from global env

// service worker
const redis = Redis.fromEnv()


// module worker
export default {
  async fetch(request: Request, env: Bindings) {
    const redis = Redis.fromEnv(env)
    // ...
  }
}
```

* [Documentation](https://docs.upstash.com/redis/tutorials/cloudflare_workers_with_redis)

## Fastly

Fastly introduces a concept called
[backend](https://developer.fastly.com/reference/api/services/backend/). You
need to configure a backend in your `fastly.toml`. An example can be found
[here](https://github.com/upstash/upstash-redis/blob/main/examples/fastly/fastly.toml).
Until the fastly api stabilizes we recommend creating an instance manually:

```ts theme={"system"}
import { Redis } from "@upstash/redis/fastly"

const redis = new Redis({
  url: <UPSTASH_REDIS_REST_URL>,
  token: <UPSTASH_REDIS_REST_TOKEN>,
  backend: <BACKEND_NAME>,
})
```

* [Code example](https://github.com/upstash/upstash-redis/tree/main/examples/fastly)
* [Documentation](https://blog.upstash.com/fastly-compute-edge-with-redis)

## Deno

Examples: [Deno Deploy](https://deno.com/deploy),
[Netlify Edge](https://www.netlify.com/products/edge/)

```ts theme={"system"}
import { Redis } from "https://deno.land/x/upstash_redis/mod.ts"

const redis = new Redis({
  url: <UPSTASH_REDIS_REST_URL>,
  token: <UPSTASH_REDIS_REST_TOKEN>,
})

// or
const redis = Redis.fromEnv();
```
