setMode

setMode is a function that updates the user's preferred mode.

It accepts one of three string values: "light", "dark", or "system".

This updates both the visual mode and the persisted preference in localStorage.

Usage

		<script lang="ts">
	import { setMode } from "mode-watcher";
</script>
 
<button onclick={() => setMode("light")}>Set Light Mode</button>
<button onclick={() => setMode("dark")}>Set Dark Mode</button>
