Nuxt

Nuxt is the full-stack framework for Vue. Nuxt 4 (2025) simplifies directory structure and enhances performance with the Nitro server engine.

When to Use

• Vue Applications: The de-facto standard for production Vue apps.
• Universal Rendering: Switch between SSR, SSG, and CSR per-route.
• Module Ecosystem: rich modules (Nuxt Image, Nuxt Content, Pinia).

Quick Start

Nuxt auto-imports components and composables.

<script setup>
// useFetch is auto-imported
const { data: quote } = await useFetch("/api/quote");
</script>

<template>
  <blockquote>{{ quote.text }}</blockquote>
</template>

Core Concepts

Nitro Engine

Nuxt’s server engine. It builds your server to run anywhere (Node, Deno, Bun, Edge/Serverless) without config.

Auto-Imports

You don’t need to import { ref } from 'vue' or import UserCard from './components/UserCard.vue'. Nuxt does it for you.

Server Routes

server/api/hello.ts creates an API endpoint /api/hello.

Best Practices (2025)

Do:

• Use useFetch: It handles SSR data fetching correctly (preventing double-fetch on client).
• Use Nuxt Modules: Don’t manually configure libraries. Use @nuxt/image, @nuxtjs/tailwindcss.
• Use app/ directory: Nuxt 4 defaults code to app/ to keep root clean.

Don’t:

• Don’t use axios: Use the built-in $fetch (OFetch) which is smarter and lighter.
