Full-Stack Next.js Case Studies

1. Introduction

Next.js is a powerful React framework that enables developers to build full-stack applications with ease. This lesson focuses on practical case studies that demonstrate the capabilities and real-world applications of Next.js in full-stack development.

2. Case Studies

2.1 E-Commerce Application

An e-commerce platform built with Next.js can leverage its server-side rendering capabilities for SEO optimization and fast page loads. This case study outlines the architecture and implementation.


            // Example of a page in Next.js for listing products
            import React from 'react';
            import { getProducts } from '../lib/api';

            const ProductsPage = ({ products }) => {
                return (
                    
                        Products
                        
                            {products.map(product => (
                                {product.name}
                            ))}
                        
                    
                );
            };

            export async function getServerSideProps() {
                const products = await getProducts();
                return { props: { products } };
            }

            export default ProductsPage;

2.2 Blogging Platform

This case study illustrates how to create a blogging platform where users can create, edit, and delete posts. The platform utilizes Next.js for both the frontend and backend.


            // Example of a blog post creation form
            import React, { useState } from 'react';

            const CreatePost = () => {
                const [title, setTitle] = useState('');
                const [content, setContent] = useState('');

                const handleSubmit = async (e) => {
                    e.preventDefault();
                    await fetch('/api/posts', {
                        method: 'POST',
                        body: JSON.stringify({ title, content }),
                        headers: { 'Content-Type': 'application/json' },
                    });
                };

                return (
                    
                         setTitle(e.target.value)} placeholder="Post Title" required />
                         setContent(e.target.value)} placeholder="Post Content" required />
                        <button type="submit">Create Post</button>
                    </form>
                );
            };

            export default CreatePost;
            </code></pre>
