What is SvelteKit?
Answer
SvelteKit is the official application framework for Svelte — the equivalent of Next.js for React or Nuxt for Vue. It provides everything needed for production web apps: File-based routing (create +page.svelte files in the src/routes/ directory). Server-side rendering (SSR), static site generation (SSG), and client-side rendering — all configurable per-page. Server endpoints (+server.js) for API routes. Load functions for data fetching before rendering. Form actions for progressive enhancement. Layouts for shared UI across pages. Adapters for deploying to different platforms (Node.js, Cloudflare, Vercel, Netlify, static). SvelteKit is built on Vite for fast development and optimized production builds. It is the recommended way to build full-featured Svelte applications.
