# Method name:

siteSite.prefetchPageResources(prefetchItems: PrefetchItems)

# Method Link:

https://dev.wix.com/docs/sdk/frontend-modules/site/prefetch-page-resources.md

# Method Description:

Optimizes resource fetching of pages and popups in a site so they'll load faster.

Use the `prefetchPageResources()` method to optimize resource fetching of pages and
 popups a site's visitors are likely to visit next. When a site
 visitor navigates to those pages or popups, they'll load quicker than usual
 since some of their resources have already been retrieved.

 You can only prefetch resources from pages or popups within the current site.

 A prefetch is considered successful if the specified pages and popups exist in
 the current site. If any of the specified pages or popups do not exist, the
 prefetch operation returns an error status and lists of the pages and popups
 that were not found.

## Prefetch resources successfully

```javascript
import { site } from '@wix/site-site';

const response = await site.prefetchPageResources( {
  "lightboxes": ["First Box", "Second Box"],
  "pages": ["/first-page", "/second-page"]
} );

if(response.errors) {
  // handle errors
}

/* Promise resolves to:
 *
 * {
 *   "message": "success"
 * }
 */
```

## Prefetch resources unsuccessfully

```javascript
import { site } from '@wix/site-site';

const response = await site.prefetchPageResources( {
  "lightboxes": ["My Lightbox", "Fake Lightbox"],
  "pages": ["/my-page", "/nonexistent-page"]
} );

if(response.errors) {
  // handle errors
}

/* Promise resolves to:
 * {
 *   "message": "some resources not found",
 *   "errors": {
 *     "lightboxes": ["Fake Lightbox"],
 *     "pages": ["/nonexistent-page"]
 *   }
 * }
 */
