help SvelteKit FAQ

What does SvelteKit add on top of Svelte?

Svelte is the component framework, while SvelteKit adds routing, server rendering, layouts, load functions, form actions, and build adapters. In practice, SvelteKit is the full application framework for building sites and apps with Svelte.

How does routing work in SvelteKit?

SvelteKit uses file-based routing inside the src/routes directory. A file like src/routes/about/+page.svelte maps to an /about page, while +server.js or +server.ts can define API endpoints.

Can SvelteKit deploy to Vercel or Cloudflare?

Yes, SvelteKit uses adapters for deployment targets such as Vercel, Netlify, Node servers, and Cloudflare environments. The adapter choice controls whether the app is prerendered, server-rendered, or deployed to an edge-style runtime.

Why do people compare SvelteKit with Next.js?

Both are full-stack web frameworks with routing and server-rendered pages, but SvelteKit uses Svelte instead of React. A team choosing between them is usually choosing between the Svelte compiler model and the React ecosystem around Next.js.
