transitionHooks

Returns the transition machinery while a transition is running, otherwise null. Renderers reach the slot and boundary layers (slotSwap, boundaryHold) only through it: a transition can only be running once the machinery exists, so this never creates it (a static call that did would keep the whole machinery in every bundle that renders a Show).

Import#

import { transitionHooks } from "@shadow-js/core/extend";

Signature#

function transitionHooks(): Hooks | null

Returns#

The hooks during a transition callback or lane run, null otherwise.

  return transitionHooks()?.boundaryHold() ?? null;
