⚠️ Warning: Experimental ⚠️

Create the following files:

index.html

<div id="app"></div>
<script type="module">
import { createApp } from 'vue'
import Comp from './Comp.vue'

createApp(Comp).mount('#app')
</script>

Comp.vue

<template>
  <button @click="count++">{{ count }}</button>

export default {
  data: () => ({ count: 0 })

<style scoped>
button { color: red }
</style>

Then run:

npx vite

Go to http://localhost:3000, edit the .vue file to see changes hot-updated instantly.

• Imports are requested by the browser as native ES module imports - there's no bundling.

• The server intercepts requests to *.vue files, compiles them on the fly, and sends them back as JavaScript.

• Imports to npm packages inside .js files (and in <script> of index.html) are re-written on the fly to point to locally installed files (only packages that provide ES module builds will work - "module" field will be used if present in package.json). There is also plans to integrate with Snowpack to leverage its web_modules.

• For libraries that provide ES modules builds that work in browsers, you can also directly import them from a CDN.

• Snowpack integration
• Custom imports map support
