# Deno Deploy

> Build a page view counter on Deno Deploy backed by an Upstash Redis database.

<Snippet file="redis/start-redis-snippet.mdx" />

This is a step-by-step guide on how to use Upstash Redis to create a view
counter in your Deno deploy project.

### Create a database

Create a Redis database using [Upstash Console](https://console.upstash.com) or
[Upstash CLI](https://github.com/upstash/cli). Select the global to minimize the
latency from all edge locations. Copy the `UPSTASH_REDIS_REST_URL` and
`UPSTASH_REDIS_REST_TOKEN` for the next steps.

### Create a Deno deploy project

Go to [https://dash.deno.com/projects](https://dash.deno.com/projects) and
create a new playground project.

### 2. Edit the handler function

Then paste the following code into the browser editor:

```ts theme={"system"}
import { serve } from "https://deno.land/std@0.142.0/http/server.ts";
import { Redis } from "https://deno.land/x/upstash_redis@v1.14.0/mod.ts";

serve(async (_req: Request) => {
  if (!_req.url.endsWith("favicon.ico")) {
    const redis = new Redis({
      url: "UPSTASH_REDIS_REST_URL",
      token: "UPSTASH_REDIS_REST_TOKEN",
    });

    const counter = await redis.incr("deno-counter");
    return new Response(JSON.stringify({ counter }), { status: 200 });
  }
});
```

### 3. Deploy and Run

Simply click on `Save & Deploy` at the top of the screen.
