Svelte is a modern JavaScript framework that compiles your code to vanilla JavaScript at build time. Unlike other frameworks, Svelte doesn’t ship a runtime library, resulting in smaller bundle sizes and better performance.

Key Features

• No Runtime - Compiles to vanilla JavaScript
• Small Bundle Size - No framework overhead in production
• Reactive - Automatic reactivity without virtual DOM
• Simple Syntax - Easy to learn and write
• TypeScript Support - Full TypeScript integration

Common Use Cases

• Web Applications - Single-page applications
• Progressive Web Apps - Fast, responsive web apps
• Component Libraries - Reusable UI components
• Static Sites - SvelteKit for static site generation
• Mobile Apps - Svelte Native for mobile development

Getting Started

# Create a new Svelte app
npm create svelte@latest my-app
cd my-app
npm install
npm run dev

Basic Example

<script>
  let count = 0;
  
  function increment() {
    count += 1;
  }
</script>

<h1>Count: {count}</h1>
<button on:click={increment}>Increment</button>

<style>
  h1 {
    color: #ff3e00;
  }
</style>
