Overview

What is SvelteKit?

SvelteKit adds application structure around Svelte components. Files under the routes directory define pages and endpoints; load functions retrieve data; form actions handle submissions on the server. A project can render pages on the server, in the browser, or ahead of time, and adapters prepare the build for a chosen deployment target.

Why it matters

SvelteKit provides a documented path from UI components to a deployable web application. The official introduction and adapter guide were checked 27 September 2026. Claims about smaller bundles or faster sites are omitted because the result depends on the application and comparison.
