What is SvelteKit?permalink
SvelteKit is a framework for building extremely high-performance web apps.
Building an app with all the modern best practices is fiendishly complicated. Those practices include build optimizations, so that you load only the minimal required code; offline support; preloading pages before the user initiates navigation; and configurable rendering that allows you to render your app on the server or in the browser at runtime or at build-time. SvelteKit does all the boring stuff for you so that you can get on with the creative part.
It uses Vite with a Svelte plugin to provide a lightning-fast and feature-rich development experience with Hot Module Replacement (HMR), where changes to your code are reflected in the browser instantly.
