getOwner

Returns the current reactive owner — the lifecycle node that the next cleanup() / onCleanup() / createSignal() etc. Will be attached to.

Returns null if called outside any owner. Capture the owner with getOwner() and re-enter it later with runWithOwner(owner, fn) to attach disposables created from a callback (event handler, async resolution, etc.) back to a component's lifecycle.

Import

import { getOwner } from "solid-js";

Type signature

function getOwner(): Owner | null;

Examples

function defer<T>(fn: () => T) {
  const owner = getOwner();
  queueMicrotask(() => runWithOwner(owner, fn));
}
