SvelteKit is a framework for full-stack web development that combines routing and server-side rendering to create websites with both client-side interactivity and server-side logic. It provides the infrastructure to build a variety of application types, including single page applications and static sites.
The project utilizes an adapter-based deployment system to support multi-platform hosting. This allows a single codebase to be packaged for different environments, such as standalone Node servers, serverless edge deployments on Cloudflare, or hosted platforms like Vercel and Netlify.
The framework covers several architectural capabilities, including file-system-based routing, server-side rendering, and prerendered static generation. It also includes tools for build-time image optimization and the ability to package reusable components.
