··· 60 60 61 61 To see real Cross-Origin Storage, install the [extension](https://chromewebstore.google.com/detail/cross-origin-storage/denpnpcgjgikjpoglpjefakmdcbmlgih), open the preview URL once (the chunks are fetched and stored), then reload or open another site shipping the same Vue version: in DevTools -> Network the hashed chunks are served from the shared store instead of refetched. 62 62 63 + For local testing it's safest to load the extension unpacked from [`web-ai-community/cross-origin-storage-extension`](https://github.com/web-ai-community/cross-origin-storage-extension). 64 + 63 65 ## Browser support 64 66 65 67 The [Cross-Origin Storage API](https://github.com/WICG/cross-origin-storage) is not yet in any browser. You can try it with the [Cross-Origin Storage browser extension](https://github.com/web-ai-community/cross-origin-storage-extension). Without it, chunks load over the network as usual, so your site keeps working; it just doesn't share them.

In DevTools -> Network, the managed hashed `.js` chunks are no longer fetched; they come from the shared store instead. 61 61 62 + For local testing it's safest to load the extension unpacked from [`web-ai-community/cross-origin-storage-extension`](https://github.com/web-ai-community/cross-origin-storage-extension). 63 + 62 64 ## Options 63 65 64 66 | Option | Type | Default | Description |
