createPresence

On Solid 2, a handle that hears an AnimatePresence's exits, given to its ref: where Solid 1 has Motion's onExitComplete.

import { AnimatePresence, createPresence } from "@wardic/solid/unstable/v2"

const presence = createPresence()

<AnimatePresence ref={presence}>…</AnimatePresence>
<button disabled={presence.exiting()} onClick={async () => {
  setOpen(false)
  await presence.next("exitComplete")
  await save()
}}>Close and save</button>

Member
`exiting()`	Whether a child is leaving.
`next(name)`	A promise of the next `"exitStart"`, a child's exit starting, or `"exitComplete"`, every leaving child gone. An exit a returning child interrupts doesn't complete.
`each(name)`	Every one, for `for await`.
`when(name)`	Every one, as a memo for an effect.

ref also takes a callback, ref={(p) => (presence = p)}, handed the presence's own handle. On a server nothing leaves: exiting() is false, and next never settles.

Types

Presence: the handle, above.
PresenceEvents: what each event resolves with, by name; PresenceEvent, a name.
