Getting Started with Nuxt 4

Introduction to Nuxt 4

Nuxt 4 is the latest version of the popular Vue.js framework for building full-stack web applications. It provides a powerful foundation for creating modern web experiences with server-side rendering, static generation, and more.

What is Nuxt?

Nuxt is an intuitive framework built on top of Vue.js that makes web development enjoyable and powerful. It provides:

• File-based routing: Automatically generate routes from your file structure
• Auto-importing: Components and composables are automatically imported
• API routes: Build backend endpoints within the same project
• Unified data fetching: Use useFetch and useAsyncData for data management

Getting Started

To create a new Nuxt project, run:

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

Your application will be available at http://localhost:3000.

Key Features

1. File-Based Routing

Create files in the pages/ directory and Nuxt automatically generates routes:

pages/
  index.vue          → /
  about.vue          → /about
  blog/
    [slug].vue       → /blog/:slug

2. Server Routes

Define API endpoints in server/api/:

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

3. Server Middleware

Create middleware in server/middleware/:

// server/middleware/logging.ts
export default defineEventHandler((event) => {
    console.log('Request:', event.node.req.url)
})

Building Your First App

Start with a simple landing page and gradually add features:

1. Create a pages/index.vue file
2. Add components in components/
3. Create API routes in server/api/
4. Deploy to production
