+## Craft Cloud
+During a [build](https://craftcms.com/knowledge-base/cloud-builds), Craft Cloud deploys static assets to a CDN, so you’ll need to configure the plugin to use the appropriate URLs:
+```php
+<?php
+// config/vite.php
+
+use craft\cloud\Helper as CloudHelper;
+
+return [
+    'manifestPath' => CloudHelper::artifactUrl('dist/.vite/manifest.json'),
+    'serverPublic' => CloudHelper::artifactUrl('dist/'),
+];
+```
+This helper function returns a CDN URL that includes your project and environment identifiers, like this:
+```
+https://cdn.craft.com/{project-uuid}/builds/{environment-uuid}/artifacts/dist/
+```
+Outside of Cloud, this behaves as though it were prepended with `@web`.
+If you’d prefer to use an on-disk `manifestPath` when working locally (instead of a URL), the `CloudHelper::isCraftCloud()` function lets you switch based on the environment:
+```php
+<?php
+// config/vite.php
+
+use craft\cloud\Helper as CloudHelper;
+
+return [
+    'manifestPath' => CloudHelper::isCraftCloud() ? CloudHelper::artifactUrl('dist/.vite/manifest.json') : '@webroot/dist/.vite/manifest.json',
+    'serverPublic' => CloudHelper::artifactUrl('dist/'),
+];
+```
+Additionally, your Vite config should have [public `base`](https://vitejs.dev/guide/build.html#public-base-path) set to use the same CDN URL. In Craft Cloud’s build pipeline, this is exposed as an [`CRAFT_CLOUD_ARTIFACT_BASE_URL` environment variable](https://craftcms.com/knowledge-base/cloud-builds#build-command):
+```javascript
+// vite.config.js
+export default ({ command }) => ({
+  base: command === 'serve' ? '' : `${process.env.CRAFT_CLOUD_ARTIFACT_BASE_URL || ''}/dist/`,
+})
+```
+
