 Both the argument and the return value are serialized with [devalue](https://github.com/sveltejs/devalue), which handles types like `Date` and `Map` (and custom types defined in your [transport hook](hooks#Universal-hooks-transport)) in addition to JSON.
 
-### Refreshing queries
+### Updating queries
 
-Any query can be updated via its `refresh` method:
+Any query can be re-fetched via its `refresh` method, which retrieves the latest value from the server:
 
 ```svelte
 <button onclick={() => getPosts().refresh()}>
 	Check for new posts
 </button>
 ```
 
-> [!NOTE] Queries are cached while they're on the page, meaning `getPosts() === getPosts()`. This means you don't need a reference like `const posts = getPosts()` in order to refresh the query.
+Alternatively, if you need to update its value manually, you can use the `set` method:
+
+```svelte
+<script>
+	import { getPosts } from './data.remote';
+	import { onMount } from 'svelte';
+
+	onMount(() => {
+		const ws = new WebSocket('/ws');
+		ws.addEventListener('message', (ev) => {
+			const message = JSON.parse(ev.data);
+			if (message.type === 'new-post') {
+				getPosts().set([
+					message.post,
+					...getPosts().current,
+				]);
+			}
+		});
+		return () => ws.close();
+	});
+</script>
