Data Fetching with Server Components

1. Introduction

Server Components are a new paradigm in React that allow developers to fetch data directly on the server side. This approach optimizes the performance of web applications by reducing the amount of JavaScript sent to the client.

2. Key Concepts

• Server Components: Components that are rendered on the server and can fetch data directly.
• Data Fetching: The process of retrieving data needed for rendering a component.
• Client Components: Components that are rendered on the client side, often used for interactivity.

3. Step-by-Step Guide

Below is a step-by-step guide to fetching data using Server Components:

                import React from 'react';

                async function fetchData() {
                    const response = await fetch('https://api.example.com/data');
                    return response.json();
                }

                export default async function MyServerComponent() {
                    const data = await fetchData();
                    return (
                        

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

                import MyServerComponent from './MyServerComponent';

                function App() {
                    return (
                        

                            
                        
                    );
                }

                export default App;
                

4. Best Practices

Here are some best practices to follow when working with Server Components:

• Optimize your API calls to minimize latency.
• Use caching strategies to reduce server load.
• Ensure error handling is implemented for data fetching.
• Keep your Server Components stateless for better performance.
