 When using TypeScript, make sure your `tsconfig.json` is setup correctly.
 
-- Use a [`target`](https://www.typescriptlang.org/tsconfig/#target) of at least `ES2022`, or a `target` of at least `ES2015` alongside [`useDefineForClassFields`](https://www.typescriptlang.org/tsconfig/#useDefineForClassFields). This ensures that rune declarations on class fields are not messed with, which would break the Svelte compiler
+- Use a [`target`](https://www.typescriptlang.org/tsconfig/#target) of at least `ES2015` so classes are not compiled to functions
 - Set [`verbatimModuleSyntax`](https://www.typescriptlang.org/tsconfig/#verbatimModuleSyntax) to `true` so that imports are left as-is
 - Set [`isolatedModules`](https://www.typescriptlang.org/tsconfig/#isolatedModules) to `true` so that each file is looked at in isolation. TypeScript has a few features which require cross-file analysis and compilation, which the Svelte compiler and tooling like Vite don't do.

+## getAbortSignal
+
+Returns an [`AbortSignal`](https://developer.mozilla.org/en-US/docs/Web/API/AbortSignal) that aborts when the current [derived](/docs/svelte/$derived) or [effect](/docs/svelte/$effect) re-runs or is destroyed.
+
+Must be called while a derived or effect is running.
+
+```svelte
+<script>
+	import { getAbortSignal } from 'svelte';
+
+	let { id } = $props();
+
+	async function getData(id) {
+		const response = await fetch(`/items/${id}`, {
