Server-Side Rendering Made Easy: Next.js vs After.js

<h2\routing: the=”” key=”” difference<=”” h2=””>

The primary distinction between Next.js and After.js lies in their routing mechanisms. Next.js takes a more automated approach, mapping URLs to components based on the project’s file structure. This means you don’t need to specify routes explicitly.

// Next.js example
// pages/about.js
function AboutPage() {
  return

About Page

;
}

export default AboutPage;

In contrast, After.js relies on React Router for routing, requiring manual configuration.

// After.js example
// pages/_app.js
import { BrowserRouter, Route } from 'eact-router-dom';

function App({ Component, pageProps }) {
  return (
    
      
    
  );
}

Creating Pages: A Similar Experience

Despite their differences in routing, both frameworks offer a similar experience when it comes to creating pages. You can add React components to create pages, and they’ll be displayed in your app.

// Next.js example
// pages/index.js
function HomePage() {
  return

Home Page

;
}

export default HomePage;

// After.js example
// pages/index.js
function HomePage() {
  return

Home Page

;
}

export default HomePage;

Data Fetching: Similar Approaches

Data fetching in both Next.js and After.js occurs when the component is first rendered. You can use the getStaticProps function in Next.js or the getInitialProps method in After.js to fetch data before rendering the page.

// Next.js example
// pages/news.js
import axios from 'axios';

function NewsPage({ news }) {
  return (

{news.map((item) => (
• {item.title}

))}

  );
}

export async function getStaticProps() {
  const response = await axios.get('https://newsapi.org/v2/top-headlines');
  return {
    props: {
      news: response.data.articles,
    },
  };
}

// After.js example
// pages/news.js
import axios from 'axios';

function NewsPage({ news }) {
  return (

{news.map((item) => (
• {item.title}

))}

  );
}

NewsPage.getInitialProps = async () => {
  const response = await axios.get('undefinedapi.org/v2/top-headlines');
  return {
    news: response.data.articles,
  };
};

Environment Variables: A Key Consideration

When it comes to environment variables, Next.js offers built-in support, allowing you to create a .env.local file in your root project. After.js, on the other hand, stores environment variables in a .env file, requiring keys to be prefixed with RAZZLE_.

//.env.local (Next.js)
API_KEY=1234567890

//.env (After.js)
RAZZLE_API_KEY=1234567890

In both frameworks, environment variables are available as a property of the process.env object.

Choosing the Right Framework

Ultimately, the choice between Next.js and After.js depends on your specific needs. If you prefer a more automated routing approach, Next.js might be the better choice. However, if you need more control over routing and are comfortable with manual configuration, After.js could be the way to go.

• Next.js: Automated routing, built-in support for environment variables
• After.js: Manual routing configuration, requires prefixing environment variables with RAZZLE_
