Before You Get Started

  • I summarize key points to help you learn and review quickly.
  • Simply click on Ask AI links to dive into any topic you want.

What is Nuxt.js?

  • Summary: Nuxt.js is an open-source framework built on top of Vue.js that makes web development more intuitive and powerful. It enhances Vue with better file-based routing, layouts, and server-side rendering for improved SEO and performance.
  • Key Takeaway/Example: Prerequisites include knowing Vue.js and having Node.js installed. Nuxt adds features like static or dynamic generation, and meta tags for SEO directly in components or pages.

Setting Up Your First Nuxt.js Project

  • Summary: Start by running npx create-nuxt-app . in your project folder using npm as the package manager. Skip git init and modules for basics, then run npm run dev to start the server.
  • Key Takeaway/Example: This sets up the project in the current directory. The setup process asks for overrides and installs dependencies, leading to a welcome page at localhost:3000.

Understanding the Project Structure

  • Summary: Key files include nuxt.config.js for configuration like enabling dev tools, app.vue as the root file for markup, server for server-side logic, and public for static assets like images or robots.txt.
  • Key Takeaway/Example: The public folder serves files directly, e.g., adding text to robots.txt makes it accessible at /robots.txt. Other folders like pages, components, and layouts will be added as needed.

Creating Pages and Routing

  • Summary: Create a pages folder with files like index.vue for the homepage and about.vue for /about. Use <NuxtPage /> in app.vue to render pages. Routing is automatic based on file structure.
  • Key Takeaway/Example: Add navigation with <NuxtLink to="/">Home</NuxtLink> and <NuxtLink to="/about">About</NuxtLink>. This creates internal links without extra setup.
<template>
  <main>
    <h1>Hello World Home</h1>
  </main>
</template>

Dynamic Routes

  • Summary: For dynamic pages, create files like [id].vue in a folder like posts. Access params with route.params.id to render content based on the URL.
  • Key Takeaway/Example: Visiting /posts/1 shows "Post 1". A 404 page is auto-generated for invalid routes, which can be customized.
<template>
  <main>
    <h1>Post {{ $route.params.id }}</h1>
  </main>
</template>

Working with Layouts

  • Summary: Create a layouts folder with default.vue for shared elements like nav and footer. Use <NuxtLayout> in app.vue. Set custom layouts per page with definePageMeta({ layout: 'custom' }).
  • Key Takeaway/Example: Wrap content in <slot /> in layouts. Default applies globally unless overridden.
<template>
  <div>
    <nav>
      <NuxtLink to="/">Home</NuxtLink>
      <NuxtLink to="/about">About</NuxtLink>
    </nav>
    <slot />
    <footer>My Website Footer</footer>
  </div>
</template>

Using Components

  • Summary: Create a components folder with files like Button.vue. Components auto-import, so use them directly like <Button>My Custom Button</Button>.
  • Key Takeaway/Example: Use slots for flexible content. Nuxt handles imports, making it easier than plain Vue.
<template>
  <button class="bg-green-500 hover:bg-green-700 text-white font-bold py-2 px-4 rounded">
    <slot />
  </button>
</template>

Conclusion and Next Steps

  • Summary: Nuxt.js is ideal for larger projects needing SEO, outperforming plain Vue for client sites. It supports auth, APIs, and databases like Supabase.
  • Key Takeaway/Example: Use Nuxt for quick setup with powerful features; stick to Vue for simple SPAs. Future topics could include API fetching, composables, or auth.
