You can use Deno KV for that. Something along the lines of

const kv = await Deno.openKv();

const { value } = await kv.get<{ date: Date, data: unknown }>(["cache"])

if (value && Date.now() - value.date.getTime() <= 60 * 60 * 1000) {
  return value.data
}

const data = await (await fetch("/my/api")).json()

await kv.set(["cache"], { date: new Date(), data })

return data

const kv = await Deno.openKv();

const { value } = await kv.get<{ date: Date, data: unknown }>(["cache"])

if (value && Date.now() - value.date.getTime() <= 60 * 60 * 1000) {
  return value.data
}

const data = await (await fetch("/my/api")).json()

await kv.set(["cache"], { date: new Date(), data })

return data

Hello javi thx for your answer, will it work on Deno Deploy with read-only permission ?

Hello Aléki! No worries You need access to kv's beta for it to work on deploy
