How to use cron?

I have this test repo on deno deploy:

import express from 'express'
import { cron } from "https://deno.land/x/deno_cron/cron.ts";
const app  = express()

app.listen(3001, () => 
{ 
    console.log('\u{1F680} API running!') 
})

cron("*/60 * * * * *", () => {
  console.log('ok');
});

import express from 'express'
import { cron } from "https://deno.land/x/deno_cron/cron.ts";
const app  = express()

app.listen(3001, () => 
{ 
    console.log('\u{1F680} API running!') 
})

cron("*/60 * * * * *", () => {
  console.log('ok');
});

It does print

API running

API running

but not the console log on the cron lambda, why is it not getting called?

Cron is built right into Deno as , see https://docs.deno.com/deploy/kv/manual/cron/

I don't understand the question. Can you rephrase that?

I imagine they are asking if Deno Deploy only supports and not the package they brought up.

Right, I'm not familiar by with that particular library. It's not created by us and was last updated around when the very first Deno 1.0 release was made. Might also be that this library never worked, but was a work in progress project by someone
