Server-Side Rendering (SSR) is a technique where the web page is generated on the server and sent as a fully rendered HTML to the client. This contrasts with Client-Side Rendering (CSR), where the browser dynamically builds the page using JavaScript.
Why Use SSR? 📈
- Improved SEO: Search engines can crawl rendered content more effectively.
- Better Performance: Reduces initial load time by serving pre-rendered pages.
- Enhanced Accessibility: Ensures compatibility with older browsers and devices.

How to Implement SSR? 🧭
- Set up a server: Use Node.js, Python, or any backend language.
- Render HTML dynamically: Generate content based on user requests or data.
- Send the rendered page: Deliver the complete HTML to the client.
SSR vs CSR 🔄
| Feature | SSR | CSR |
|---|---|---|
| Rendering Location | Server | Client |
| Initial Load Speed | Faster | Slower |
| SEO Friendliness | High | Low (if JavaScript is blocked) |
Best Practices 📚
- Cache rendered pages for frequently accessed routes.
- Use streaming to improve user experience.
- Combine with static site generation (SSG) for optimal results.
