Using Vue Single-File Components improves developer experience. With Nuxt rendering strategies explained, you can write Vue components in a way that feels natural—simple, intuitive, and powerful. By automating repetitive tasks, Nuxt allows you to focus on building your full-stack Vue application with confidence and ease.

<script setup>
useSeoMeta({
  title: 'Meet Nuxt',
  description: 'The Intuitive Vue Framework.'
})
</script>

<template>
  <div id="app">
    <AppHeader />
    <NuxtPage />
    <AppFooter />
  </div>
</template>

<style>
#app {
  background-color: #020420;
  color: #00DC82;
}
</style>

Choose the rendering strategy that suits each route. With hybrid rendering, you can enjoy the best of both worlds: the speed and efficiency of a static site combined with the rich interactivity of a dynamic application.

export default defineNuxtConfig({
  routeRules: {
    // Homepage pre-rendered at build time
    '/': { prerender: true },
    // Product page generated on-demand with background revalidation
    '/products/**': { swr: true },
    // Blog post generated on-demand once until next deploy
    '/blog/**': { isr: true },
    // Admin dashboard renders only on client-side
    '/admin/**': { ssr: false },
    // Add cors headers on API routes
    '/api/**': { cors: true },
    // Redirects legacy urls
    '/old-page': { redirect: '/new-page' }
  }
})

Nuxt Core Features: Simplifying Development and Boosting Performance

Nuxt offers a comprehensive set of features that simplify development, enhance performance, and improve scalability. In this article, we will focus on its primary strengths and discuss why choose Nuxt for modern web apps as the optimal solution for modern projects. We will address all the features in detail in the following blog posts.

File-System Routing: Intuitive Route Management

One of the core features of Nuxt framework is its intuitive file-system routing. Nuxt automatically generates routes based on the pages/ directory, eliminating the need for manual configuration. Each .vue file corresponds to a route, and the naming conventions effortlessly allow for dynamic and nested routes. For example, files with names like [id].vue create dynamic routes, while nested directories define child routes. This intuitive system accelerates development and ensures a clean, organized structure for your project.

Rendering Modes

Nuxt supports multiple rendering modes to suit a variety of use cases:

  • Server-Side Rendering (SSR) - Pages are rendered on the server and sent as fully-formed HTML, enhancing performance and SEO optimization with Nuxt.

  • Static Site Generation (SSG) - Pages are pre-rendered at build time, delivering ultra-fast load speeds with a static site.
