SvelteKit Setup Guide 2025: Best CSS Frameworks, Libraries & Example Code

SvelteKit offers a lean, modern developer experience with excellent performance by default. This guide shows a pragmatic setup, recommended CSS frameworks, useful libraries, and a small example so you can ship quickly.

1) Create Your Project

npm create svelte@latest my-app
cd my-app
npm install
npm run dev
      

2) Best CSS Options

• Tailwind CSS — utility-first, fast design iteration.
• DaisyUI — Tailwind component library to ship UI faster.
• Skeleton UI — Svelte-first component kit with themes.

3) Must-Have Libraries

• @tanstack/svelte-query — declarative data fetching/caching.
• svelte-forms-lib — forms, validation, and helpers.
• motion (or svelte-motion) — smooth, composable animations.
• @supabase/supabase-js — auth, DB, and storage in minutes.

4) Minimal Example

Create src/routes/+page.svelte and paste:

// src/routes/+page.svelte
<script lang="ts">
  import { onMount } from 'svelte';
  let name = 'World';
  onMount(() => console.log('SvelteKit ready'));
</script>

<main class="p-8 space-y-4">
  <h1 class="text-3xl font-bold">Hello {name}! 👋</h1>
  <p>This is a clean SvelteKit starter with Tailwind.</p>
</main>
      

5) Deployment Tip

Use the right adapter for your target (Vercel, Node, Cloudflare). Keep images optimized and prefer SSR/SSG for SEO-critical pages.
