Live Counter.

Increment and decrement without a full page reload. Nimbus handles the state server-side; Unpoly swaps only the counter fragment.

How it works

You click + or −. The form submits via Unpoly with up-submit.

Nimbus increments / decrements the value in server-side session state and re-renders the fragment.

Unpoly swaps only #counter-fragment — no full page reload, no JavaScript state management.

handlers/counter.go

func (CounterHandler) Increment(
  ctx *http.Context,
) error {
  count := ctx.Session().
    GetInt("count", 0)

  count++
  ctx.Session().Put("count", count)

  return ctx.View("demos/counter/fragment",
    nimbus.Data{"count": count},
  )
}
