a basic api:
```
  import { Application, Router } from 'https://deno.land/x/oak/mod.ts';
  import { Client } from "https://deno.land/x/postgres@v0.17.0/mod.ts";

  const app = new Application();
  const router = new Router();

  // Configure database connection
  const client = new Client({
    hostname: 'usmidsap02',
    port: 5432,
    user: 'api',
    password: '',
    database: 'ubm',
  });

  await client.connect();

  // Define a route to retrieve values from the database
  router.get('/', async (ctx) => {
    ctx.response.body = "live";
  });
  // Define a route to retrieve values from the database
  router.get('/api/data', async (ctx) => {
    const result = await client.queryObject("SELECT * FROM rlarp.pl LIMIT 10");
    console.log(result.rows); // [{id: 1, name: 'Carlos'}, {id: 2, name: 'Johnru'}, ...]
    //const result = await client.query('SELECT 1');
    ctx.response.body = result.rows;
  });

  app.use(router.routes());
  app.use(router.allowedMethods());

  // Start the server
  console.log('Server is running on http://localhost:8085');
  await app.listen({ port: 8085 });
