Nuxt 3 represents a major evolution in the Vue.js meta-framework landscape. Built from the ground up with TypeScript, it offers improved performance, better developer experience, and leverages the latest Vue 3 features including the Composition API.

Nuxt 3 is built on Vue 3, which means you get access to all the latest features:

• Composition API: Write more reusable and maintainable code
• Multiple root elements: No more wrapper divs required
• Better TypeScript support: First-class TypeScript integration

The new Nitro engine provides:

• Universal deployment: Deploy anywhere with zero configuration
• API routes: Built-in API handling with file-based routing
• Edge-side rendering: Faster response times globally

Say goodbye to import statements for:

• Vue composition functions (ref, reactive, computed)
• Nuxt composables (useHead, useFetch, useState)
• Your own utilities and components

Getting started with Nuxt 3 is straightforward:

npx nuxi@latest init my-nuxt-app
cd my-nuxt-app
npm install
npm run dev

Nuxt 3 continues the tradition of file-based routing. Create a file in the pages/ directory, and it automatically becomes a route:

pages/
├── index.vue          # → /
├── about.vue          # → /about
├── blog/
│   ├── index.vue      # → /blog
│   └── [slug].vue     # → /blog/:slug
└── [...slug].vue      # → catch-all route

Nuxt 3 introduces new composables for data fetching:

<script setup>
// Server-side rendering with caching
const { data: posts } = await useFetch('/api/posts')

// Client-side only
const { data: stats } = await $fetch('/api/stats')

// With refresh capability
const { data: user, refresh } = await useFetch('/api/user')
</script>

Managing SEO is easier than ever with the useSeoMeta composable:

<script setup>
useSeoMeta({
  title: 'My Amazing Page',
  description: 'This page is truly amazing.',
  ogImage: '/og-image.jpg',
  twitterCard: 'summary_large_image'
})
</script>

Create API endpoints by adding files to the server/api/ directory:

// server/api/hello.js
export default defineEventHandler((event) => {
  return {
    message: 'Hello from Nuxt 3!'
  }
})

Nuxt 3's universal deployment means you can deploy to various platforms with zero configuration:

• Static hosting: npm run generate for static sites
• Node.js: npm run build for SSR applications
• Edge functions: Deploy to Vercel, Netlify, Cloudflare Workers

Nuxt 3 brings significant improvements in performance, developer experience, and deployment flexibility. Whether you're building a static site, a server-rendered application, or a hybrid solution, Nuxt 3 provides the tools you need.

The migration from Nuxt 2 might require some changes, but the benefits in terms of performance and developer experience make it worthwhile. Start your next project with Nuxt 3 and experience the future of Vue.js development.
