Svelte is a radical new approach to building user interfaces. Whereas traditional frameworks like React and Vue do the bulk of their work in the browser, Svelte shifts that work into a compile step that happens when you build your app. Instead of using techniques like virtual DOM diffing, Svelte writes code that surgically updates the DOM when the state of your app changes, resulting in exceptionally fast and lightweight applications.
Before starting with Svelte, ensure you have Node.js installed and basic knowledge of HTML, CSS, and JavaScript.
The easiest way to start a new Svelte project is using the official template with Vite, the next-generation frontend tooling.
Terminal
npm create vite@latest my-app -- --template sveltecd my-app && npm installnpm run devnpm create svelte@latest my-app (SvelteKit)💡 Pro Tip: Svelte 5 introduces Runes — a new simpler syntax for reactive state management. SvelteKit is the official framework for building full-stack Svelte applications.
