Expert guidance for shadcn-svelte, a Svelte 5 port of shadcn/ui. Use this skill when working with shadcn-svelte components, installing UI components via CLI, implementing forms with Superforms/Formsnap, adding dark mode with mode-watcher, creating data tables with TanStack Table, theming with Tailwind CSS v4 and OKLCH colors, or building custom component registries.

shadcn-svelte

A Svelte 5 / SvelteKit port of shadcn/ui - beautifully designed, accessible components built with Bits UI and Tailwind CSS.

Quick Start

Installation

# SvelteKit
pnpm dlx shadcn-svelte@latest init

# Add components
pnpm dlx shadcn-svelte@latest add button card dialog

Basic Usage

Components use namespace imports:

<script lang="ts">
  import * as Card from "$lib/components/ui/card/index.js";
  import { Button } from "$lib/components/ui/button/index.js";
</script>

<Card.Root>
  <Card.Header>
    <Card.Title>Title</Card.Title>
    <Card.Description>Description</Card.Description>
  </Card.Header>
  <Card.Content>Content here</Card.Content>
  <Card.Footer>
    <Button>Action</Button>
  </Card.Footer>
</Card.Root>

Key Patterns

Component Import Pattern

<!-- Compound components (most components) -->
import * as Dialog from "$lib/components/ui/dialog/index.js";

<!-- Single components -->
import { Button } from "$lib/components/ui/button/index.js";
import { Input } from "$lib/components/ui/input/index.js";

Form Implementation

Use Superforms + Formsnap for forms:

<script lang="ts">
  import * as Form from "$lib/components/ui/form/index.js";
  import { superForm } from "sveltekit-superforms";

  let { data } = $props();
  const form = superForm(data.form);
</script>

<form method="POST" use:form.enhance>
  <Form.Field {form} name="email">
    <Form.Control>
      {#snippet children({ props })}
        <Input {...props} type="email" />
      {/snippet}
    </Form.Control>
    <Form.FieldErrors />
  </Form.Field>
</form>

Dark Mode

<!-- +layout.svelte -->
<script lang="ts">
  import { ModeWatcher } from "mode-watcher";
</script>

<ModeWatcher />
{@render children()}

Toggle with toggleMode(), setMode("dark"), or resetMode() from mode-watcher.
