DialogSSR

Server-Side Rendering

Dialogs will work fine by default in a server-side rendering environment, but keep in mind the following scenario to avoid SSR hydration issues:

When unmountOnClose is set to false (default value is true), Dialog will keep the element rendered at all times, but since it uses React Portal underneath, and portals do not support SSR, it'll result in a hydration error. For SSR environments, it's advised to always set this property to true.
