The original title is "Stop Hardcoding UIs: Server-Driven UI in Next.js"

Short summary

Server-Driven UI (SDUI) shifts layout control from the frontend to the backend by sending component definitions as JSON. The Next.js frontend acts as a dumb renderer, mapping component names from the API response to pre-built React components. This enables instant A/B tests, per-user personalization, and layout restructuring without frontend deployments.

• •Backend sends JSON payload defining which components to render and in what order
• •Next.js maps component names to a registry and dynamically mounts React components
• •Enables A/B testing and personalization without frontend deployments
