SvelteKit routing uses file-based naming conventions where +page.svelte defines routes and +layout.svelte wraps them. This guide prescribes a quick-start skeleton to scaffold multi-route apps with nested layouts and error boundaries.

SvelteKit layout groups let you compose UIs without URL changes. You need them when multiple routes share a layout but should not alter the URL path, enabling nested layout composition for scalable interfaces.

SSR hydration in SvelteKit attaches interactivity to server-rendered HTML. This guide provides hydration guidelines and patterns to ensure robust apps during scaffolding and maintenance without mismatches.

Yes, +server.ts files create API routes in SvelteKit. This naming convention defines server-side endpoints within your project structure, handling requests alongside pages and layouts for full-stack capabilities.

Use +error.svelte files to handle errors in SvelteKit routing. This guide provides error handling patterns that act as error boundaries within your layout structure, catching load failures and rendering fallback UI.

SvelteKit nested layouts fail when file naming conventions are incorrect. Ensure +layout.svelte files are placed in the correct directory hierarchy to wrap child +page.svelte routes, establishing a consistent structure for scalable apps.
