 If you use one of the [streaming server rendering APIs](/reference/react-dom/server) (or a framework that relies on them), React will also use your `<Suspense>` boundaries to handle errors on the server. If a component throws an error on the server, React will not abort the server render. Instead, it will find the closest `<Suspense>` component above it and include its fallback (such as a spinner) into the generated server HTML. The user will see a spinner at first.
