No SSR

The No-SSR component defers the rendering of children components from the server to the client.

Introduction

No-SSR is a utility component that prevents its children from being rendered on the server, deferring their rendering to the client instead. This can be useful in a variety of situations, including:

To create an escape hatch for broken dependencies that don't support server-side rendering (SSR)
To improve the time to first paint by only rendering above the fold
To reduce the rendering time on the server
To turn on service degradation when the server load is too heavy
To improve the Time to Interactive (TTI) by only rendering what's important (using the defer prop)

The demo below illustrates how this component works:

Server and Client

<Box sx={{ p: 2, bgcolor: 'primary.main', color: 'primary.contrastText' }}>
  Server and Client
</Box>
<NoSsr>
  <Box
    sx={{ p: 2, bgcolor: 'secondary.main', color: 'secondary.contrastText' }}
  >
    Client only
  </Box>
</NoSsr>

<Box sx={{ p: 2, bgcolor: 'primary.main', color: 'primary.contrastText' }}>
  Server and Client
</Box>
<NoSsr>
  <Box
    sx={{ p: 2, bgcolor: 'secondary.main', color: 'secondary.contrastText' }}
  >
    Client only
  </Box>
</NoSsr>

Delay client-side rendering

You can also use No-SSR to delay the rendering of specific components on the client-side—for example, to let the rest of the application load before an especially complex or data-heavy component.

The following demo shows how to use the defer prop to prioritize rendering the rest of the app outside of what is nested within No-SSR:
