Nuxt provides the `<NuxtClientFallback>` component to render its content on the client if any of its children trigger an error in SSR.
|
|
|
|
::note{to="/docs/guide/going-further/experimental-features#clientfallback"}
|
|
This component is experimental and in order to use it you must enable the `experimental.clientFallback` option in your `nuxt.config`.
|

|
```vue [pages/example.vue]
|
|
<template>
|
|
<div>

<Sidebar />

|
<!-- this component will be rendered on client-side -->
|
|
<NuxtClientFallback fallback-tag="span">
|
|
<Comments />
|
|
<BrokeInSSR />
|
