How does React Suspense work with server-side rendering?

React Suspense allows you to defer rendering part of your UI until some condition is met, like data fetching. When combined with server-side rendering (SSR), it helps in loading data before the page is sent to the client, improving performance and user experience.

Can you explain how to implement it in a project?

Sure! First, ensure you're using React 18 or later. You can wrap your components with <Suspense> and use a data-fetching library that supports Suspense, like React Query. Then, on the server, you can fetch the data and render the components accordingly.

What are the benefits of using Suspense with SSR?

The main benefits include improved loading times, better user experience, and reduced client-side JavaScript execution. It allows users to see content faster while the rest of the app loads.

Are there any limitations I should be aware of?

Yes, some limitations include potential issues with error boundaries and the need for careful handling of loading states. Also, not all libraries support Suspense yet.
