runWithOwner

Executes fn with the given owner set as the current owner. Any reactive primitives (createSignal, createMemo, createEffect, onCleanup, cleanup, etc.) created inside fn are attached to that owner, so they are disposed when the owner is disposed.

The classic pattern: capture the current owner with getOwner() inside a component, then re-enter it from a callback (event handler, async resolve, setTimeout) so disposables created in the callback get cleaned up with the component.

Import

import { runWithOwner } from "solid-js";

Type signature

function runWithOwner<T>(owner: Owner | null, fn: () => T): T;

Examples

function delayed<T>(ms: number, fn: () => T) {
  const owner = getOwner();
  setTimeout(() => runWithOwner(owner, fn), ms);
}
