Core Concepts

What is Astro?

Astro is a web framework that makes websites FAST. It does this by removing JavaScript you don’t need.

Here’s what makes it different:

Think of Astro’s “islands” like small power stations. They only turn on when someone needs them. Everything else? Just plain, fast HTML.

Out of all the tools I’ve used in the past ten years, Astro is the one that makes me most excited about where web development is going. - Brian Holt

Want to mix different frameworks? No problem:

---
import SvelteNav from './Nav.svelte';
import ReactPost from './Post.jsx';
import VueFooter from './Footer.vue';
---

<SvelteNav client:load />
<ReactPost client:load />
<VueFooter client:load />

What is Next.js?

Next.js supercharges React apps. Built by Vercel, it helps you build React apps faster and better.

Think of Next.js as a powerful tool for building highly interactive web applications. It’s the go-to choice for big names like TikTok, Twitch, and Hulu when they need to:

• Update content in real-time
• Check who users are
• Show different content to different users
• Keep track of complex data

How They Compare

Let’s look at the key differences between Astro and Next.js:

1. Page Loading Methods

These frameworks handle content in totally different ways:

Think of it this way: Astro is like picking items from a menu (you only get what you order), while Next.js serves the whole buffet (whether you’re hungry or not).

That’s probably why Trivago picked Astro for their content-heavy pages, but Twitch went with Next.js for their interactive features.

2. Working with each framework

Here’s what you’ll get with each:

3. Getting Data

4. Using Components

Best Uses

Let’s break down which projects work best with each framework:

When to Use Astro

Astro can do almost anything that major frameworks like Next.js and SvelteKit, etc., can do. It’s so powerful, it’s so flexible, it’s so simple. - James Q Quick

Astro shines when you need speed and content delivery:

What makes Astro stand out:

• Starts with zero JavaScript
• Adds interactivity only where needed
• Handles content right out of the box
• Plays nice with your favorite UI tools

Astro ships ZERO JavaScript by default. It only adds JavaScript where you need it.

Think about building a blog with Astro: Your articles load as pure HTML. JavaScript loads ONLY for things like comments.

When to Use Next.js

Next.js has made it easier for us to scale and build on the Web with fewer people–there’s only one of us, and we’re putting our sites in front of some of the world’s largest brands. - Adham Foda CTO KidSuper

Next.js powers bigger, more complex projects:

What makes Next.js stand out:

• Supports server-side rendering
• Optimizes performance with automatic code splitting
• Manages images
• Controls page routing

Next.js includes JavaScript on every page. But don’t worry - it splits the code automatically to keep things fast.

Think about building a blog with Next.js: Pages load with JavaScript included, making navigation between posts instant.

Wrap-up

When deciding between Astro and Next.js, consider your project’s needs. Astro is ideal for content-heavy sites that require less JavaScript, while Next.js is better suited for highly interactive web applications that demand more dynamic capabilities.

Both tools keep getting better at what they do. Your pick? It comes down to what you’re building in 2024.
