Native Vue.js SFC Support in the Browser.

Writing Vue code is a joy, largely due to the elegance of Single-File Components (SFCs). The ability to colocate your <template>, <script>, and <style> in a single `.vue` file is incredibly productive. The problem? Browsers cannot natively read `.vue` files. They require a heavy build step via Vite or Webpack.

Client-Side Vite Compilation

NitroIDE is the premier Vue online compiler because it runs the entire Vite bundler and Vue compiler directly inside the browser using WebAssembly. There are no remote servers compiling your code. You write a `.vue` file, and our local engine transforms it into executable JavaScript in under 50 milliseconds.

const count = ref(0);
</script>

<template>
  <div class="counter-app">
    <h1>NitroIDE + Vue 3</h1>
    <button @click="count++">Count is: {{ count }}</button>
  </div>
</template>

<style scoped>
.counter-app {
  text-align: center;
  padding: 2rem;
}
</style>

Voler Language Server: True Vue development requires more than just compilation. NitroIDE runs Volar (the official Vue language server) locally in a Web Worker, giving you flawless TypeScript integration inside your <template> blocks.

Instant Hot Module Replacement

Because the Vite server is running adjacent to your code in the same browser tab, Hot Module Replacement (HMR) operates flawlessly. When you tweak a CSS rule inside your `
