svelte-theme-select
Customizable Svelte components for theme selection (light mode / dark mode) inspired by TailwindCSS.
About
The TailwindCSS site is a great example of excellent UX and the theme select option is particularly nice. A simple icon gives access to a menu to set the theme to light mode or dark mode, or allow the system to automatically switch based on your device configuration (which can change based on the time of day).
A particularly nice touch is that it shows if the default system mode has been overridden using a different icon color.
For mobile users, where the navigation bar shrinks to become an expandable menu, they have a larger-hit-target version providing the same features.
This project re-creates these UI widgets and provides the system to persist and apply the selected theme in your SvelteKit project. Please refer to TailwindCSS Dark Mode documentation for how to use dark mode styles within your app.
Usage
Install Package
Install using your package manager of choice:
pnpm i svelte-theme-selectAdd to root +layout.svelte
Create an instance of the theme manager in your root src/routes/+layout.svelte file and include the <Theme> component which writes the JS into the page to apply the theme. The <ThemeToggle> component provides the desktop icon and menu, the <ThemeSelect> component provides the mobile friendly equivalent. This is a cut-down layout, checkout the ready made templates available from TailwindUI.
<script lang="ts">
import { createThemeSwitcher, Theme, ThemeToggle, ThemeSelect } from 'svelte-theme-select'
import '../app.postcss'
createThemeSwitcher()
</script>
<nav>
<!-- desktop navigation -->
<div class="hidden md:block">
<!-- logo and rest of options -->
<ThemeToggle />
</div>
<!-- mobile navigation -->
<div class="block md:hidden">
<!-- logo and rest of options -->
<ThemeSelect />
</div>
</nav>
<slot />
<Theme />Configure TailwindCSS dark-mode
Configure TailwindCSS to toggle dark mode manually using a class:
const config = {
content: ['./src/**/*.{html,js,svelte,ts}'],
theme: {
extend: {},
},
darkMode: 'class',
plugins: [],
}
module.exports = configDefine light / dark background colors
Set the light and dark mode backgrounds to use in your src/app.html app shell:
<body class="bg-slate-100 dark:bg-slate-900">
<div>%sveltekit.body%</div>
</body>Everything should then be in place to design using the TailWindCSS classes including the dark: prefix for when dark mode is active.
Customizing the Widget Style
The UI widgets can be customized to match whatever TailwindCSS colors scheme you are using, the default icons can be replaced if desired, and the "Light", "Dark", and "System" labels replaced.
