Introduction to Sustainable Development

Sustainable development in tech means creating applications that are efficient, scalable, and have minimal environmental impact. With the growing demand for web applications, it’s crucial to adopt practices that reduce energy consumption and improve performance.

Key Terminology

• Sustainability: Building applications that are efficient and have a minimal environmental footprint.
• Scalability: The ability of an application to handle increased load without compromising performance.
• Efficiency: Using resources in the best possible way to achieve the desired outcome.

Getting Started with Next.js

Next.js is a powerful framework for building React applications. It offers features like server-side rendering and static site generation, which are great for creating sustainable applications.

Setup Instructions

# Install Node.js if you haven't already
# Then, create a new Next.js app
npx create-next-app@latest my-sustainable-app
cd my-sustainable-app
npm run dev

Simple Example: Static Site Generation

// pages/index.js
export default function Home() {
  return (
    

      
Welcome to My Sustainable App
      
This is a simple static page.
    
  );
}

Progressively Complex Examples

Example 1: Server-Side Rendering

// pages/index.js
export async function getServerSideProps() {
  // Fetch data from an API or database
  const data = await fetch('https://api.example.com/data').then(res => res.json());
  return { props: { data } };
}

export default function Home({ data }) {
  return (
    

      
Data from Server
      
{JSON.stringify(data, null, 2)}

  );

}

This example demonstrates server-side rendering, where data is fetched on each request, ensuring fresh content.

Example 2: Dynamic Routing

// pages/posts/[id].js
import { useRouter } from 'next/router';

export default function Post() {
  const router = useRouter();
  const { id } = router.query;

  return 
Post: {id}
;
}

Example 3: API Routes

// pages/api/hello.js
export default function handler(req, res) {
  res.status(200).json({ message: 'Hello, world!' });
}

Common Questions & Answers

1. What is Next.js?

   Next.js is a React framework that enables features like server-side rendering and static site generation.

2. Why is sustainability important in web development?

   It reduces the environmental impact and improves the efficiency and performance of web applications.

3. How does server-side rendering contribute to sustainability?

   It reduces the amount of JavaScript sent to the client, improving load times and reducing energy consumption.

4. What are static site generation benefits?

   Static sites are pre-rendered, making them fast and reducing server load.

5. How can I troubleshoot common Next.js issues?

   Check the Next.js documentation, ensure your Node.js version is up-to-date, and verify your code syntax.

Troubleshooting Common Issues

Ensure your Node.js version is compatible with Next.js. Check the official documentation for version requirements.

If you encounter a build error, try deleting the .next folder and rebuilding your app.

Practice Exercises

• Create a new page using static site generation and display a list of items.
• Implement server-side rendering to fetch and display data from an API.
• Set up a dynamic route and create pages based on URL parameters.

Remember, practice makes perfect! Keep experimenting with Next.js features to build sustainable applications. 🌟
