This component is experimental and in order to use it you must enable the `experimental.clientFallback` option in your `nuxt.config`.
::
## Events
- `@ssr-error`: Event emitted when a child triggers an error in SSR. Note that this will only be triggered on the server.
```vue
<template>
<NuxtClientFallback @ssr-error="logSomeError">
<!-- ... -->
</NuxtClientFallback>
</template>
```
## Props
- `placeholderTag` | `fallbackTag`: Specify a fallback tag to be rendered if the slot fails to render.
- **type**: `string`
- **default**: `div`
- `placeholder` | `fallback`: Specify fallback content to be rendered if the slot fails to render.
- **type**: `string`
- `keepFallback`: Keep the fallback content if it failed to render server-side.
- **type**: `boolean`
- **default**: `false`
```vue
<template>
<!-- render <span>Hello world</span> server-side if the default slot fails to render -->
<NuxtClientFallback fallback-tag="span" fallback="Hello world">
<BrokeInSsr />
</NuxtClientFallback>
</template>
```
## Slots
- `#fallback`: specify content to be displayed server-side if the slot fails to render.
```vue
<template>
<NuxtClientFallback>
<!-- ... -->
<template #fallback>
<!-- this will be rendered on server side if the default slot fails to render in ssr -->
<p>Hello world</p>
</template>
