Svelte

Also known as: Svelte.js / SvelteKit

Rich Harris's compiler-based UI framework that eliminates the virtual DOM by compiling to minimal JS at build time, resulting in high runtime performance. SvelteKit handles full-stack SSR/SSG needs.


Overview

Svelte is a compiler that transforms components into pure JavaScript at build time, eliminating virtual DOM overhead and producing small bundles. Svelte 5 introduced the Runes API ($state, $derived, $effect) for more explicit reactivity.

Relationship with SvelteKit

SvelteKit is Svelte's official full-stack framework, equivalent to Next.js or Nuxt. It provides file-based routing, SSR, SSG, and API routes, with Vite as its build tool.
