Deno Deploy

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 or 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 and create a new playground project.

2. Edit the handler function​

Then paste the following code into the browser editor:

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: 'https://global-smart-lizard-32830.upstash.io',
            token: 'AXV0NzFjNjQtZjg1Yy00YTgdfg765tyjhZDg3MmUyYmQ6765MDg',
        })

        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.
