Adds an experimental flag `clientPrerender` to prerender your prefetched pages on the client with the [Speculation Rules API](https://developer.mozilla.org/en-US/docs/Web/API/Speculation_Rules_API).
|
||
|
|
|
||
|
|
```js
|
||
|
|
// astro.config.mjs
|
||
|
|
{
|
||
|
|
prefetch: {
|
||
|
|
prefetchAll: true,
|
||
|
|
defaultStrategy: 'viewport',
|
||
|
|
},
|
||
|
|
experimental: {
|
||
|
|
clientPrerender: true,
|
||
|
|
},
|
||
|
|
}
|
||
|
|
```
|
||
|
|
|
||
|
|
Enabling this feature overrides the default `prefetch` behavior globally to prerender links on the client according to your `prefetch` configuration. Instead of appending a `<link>` tag to the head of the document or fetching the page with JavaScript, a `<script>` tag will be appended with the corresponding speculation rules.
|
||
|
|
|
||
|
|
Client side prerendering requires browser support. If the Speculation Rules API is not supported, `prefetch` will fallback to the supported strategy.
|
||
|

|
See the [Prefetch Guide](https://docs.astro.build/en/guides/prefetch/) for more `prefetch` options and usage.
