What is server-side rendering (SSR) in Angular?

Short answer: SSR means rendering the app’s HTML on the server before sending it to the client. With Angular Universal, the app runs on Node.js server rendering Angular components into HTML. The client then takes over via Angular’s client-side rendering (hydration).

Real-world example (ShopNest)

ShopNest admin can be built in Angular with modules/components, services for API calls, and reactive forms for product edit.

Say this in the interview

1. Define — one clear sentence (the short answer above).
2. Example — relate it to a project like ShopNest or your real work.
3. Trade-off — when you would not use it.
