SvelteKit

SvelteKit is the official application framework built on Svelte for building full-stack web applications. It provides file-based routing, server-side rendering, static site generation, and API endpoints in a single unified project structure. Each route can independently choose its rendering strategy.

The framework handles layout nesting, data loading with server-side load functions, form actions for progressive enhancement, error handling, and environment variable management. Adapters allow deployment to Vercel, Netlify, Cloudflare, Node.js servers, and static hosts. For web developers familiar with Svelte, SvelteKit provides production-ready scaffolding for complete applications, similar to what Next.js provides for React or Nuxt provides for Vue, with the performance benefits of Svelte's compile-time approach carrying through to the full-stack experience.
