Getting Started with Nuxt 3

Nuxt 3 is a powerful framework built on top of Vue 3 that makes building modern web applications a breeze. In this comprehensive guide, we'll walk through everything you need to know to get started.

Why Choose Nuxt 3?

Nuxt 3 offers several compelling advantages:

Server-Side Rendering (SSR) - Better SEO and faster initial page loads
Auto-imports - No need to manually import components and composables
File-based routing - Automatic route generation from your file structure
TypeScript support - First-class TypeScript integration
Hybrid rendering - Mix SSR, SSG, and CSR as needed

Installation

Getting started is simple. Create a new Nuxt 3 project with:

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

Project Structure

A typical Nuxt 3 project structure looks like this:

my-app/
├── pages/
├── components/
├── composables/
├── layouts/
├── public/
├── server/
└── nuxt.config.ts

Creating Your First Page

Create a new file pages/index.vue:

<template>
  <div>
    <h1>Welcome to Nuxt 3!</h1>
    <p>This is your first page.</p>
  </div>
</template>

That's it! Nuxt automatically creates a route for this page.

Next Steps
