Virtual DOM on the Server — SSR and Hydration

In this tutorial, you will learn about Virtual Dom on the Server. We cover key concepts, practical examples, and best practices to help you master this topic.

Server-side rendering with Virtual DOM involves rendering the component tree to HTML on the server, then "hydrating" the static HTML with event handlers on the client.

// React SSR
import { renderToString } from 'react-dom/server';
const html = renderToString(<App />);

// The client hydrates the pre-rendered HTML
import { hydrateRoot } from 'react-dom/client';
hydrateRoot(document.getElementById('root'), <App />);
