Sveltekit Structure

SvelteKit Structure

Quick Start

File types: +page.svelte (page) | +layout.svelte (wrapper) | +error.svelte (error boundary) | +server.ts (API endpoint)

Routes: src/routes/about/+page.svelte → /about | src/routes/posts/[id]/+page.svelte → /posts/123

Layouts: Apply to all child routes. +layout.svelte at any level wraps descendants.

Example

src/routes/├── +layout.svelte              # Root layout (all pages)├── +page.svelte                # Homepage /├── about/+page.svelte          # /about└── dashboard/    ├── +layout.svelte          # Dashboard layout (dashboard pages only)    ├── +page.svelte            # /dashboard    └── settings/+page.svelte   # /dashboard/settings

<!-- +layout.svelte --><script>	let { children } = $props();</script>
<nav><!-- Navigation --></nav><main>{@render children()}</main><footer><!-- Footer --></footer>
