2. Server-side Fetching and Data Management with Next.js

This blog focuses on the power of Next.js for server-side data fetching, routing, and API integration.
• Server-side Fetching in Next.js:
• Next.js allows data fetching both on the server side (SSR) and client side. This is useful for performance optimization and SEO, especially when you need to pre-render content on the server before sending it to the client.
• In this project, API routes are set up using Next.js to handle data fetching for items. This includes endpoints for fetching item lists, adding new items, updating, and deleting them.
• API Routes in Next.js:
• The API routes are used to handle requests such as GET, POST, PUT, and DELETE to manage the items. These API routes run on the server, ensuring that sensitive data and logic are kept secure.
• For example, GET /api/items fetches the list of items, and POST /api/items adds a new item to the database.
• Using fetch() in the components allows the frontend to interact with these API routes seamlessly, ensuring data updates are reflected in real-time.
• Why is Next.js good for this?
• Next.js simplifies data fetching by providing both static and dynamic methods (e.g., getServerSideProps, getStaticProps, API routes).
• It ensures that the content is delivered quickly and SEO-friendly by enabling server-side rendering (SSR).
