Example Deno Application

Here’s a simple Deno server:
server.ts
import { serve } from "https://deno.land/std@0.208.0/http/server.ts";
import { Client } from "https://deno.land/x/postgres@v0.17.0/mod.ts";

const client = new Client({
  hostname: "db",
  port: 5432,
  user: "db",
  password: Deno.env.get("DB_PASSWORD"),
  database: "db",
});

await client.connect();

const handler = async (req: Request): Promise<Response> => {
  const result = await client.queryObject(
    "SELECT COUNT(*) as count FROM requests"
  );
  
  return new Response(
    JSON.stringify({ count: result.rows[0].count }),
    { headers: { "content-type": "application/json" } }
  );
};

serve(handler, { port: 8000 });
With zerops.yaml: 
zerops:
  - setup: api
    build:
      base: deno@1
      buildCommands:
        - deno cache server.ts
      deployFiles:
        - server.ts
    
    run:
      base: deno@1
      ports:
        - port: 8000
      start: deno run --allow-net --allow-env server.ts
