# <a id="fusion.application.overview"></a>Hilla Guides

Guides that don’t depend on the frontend framework are documented only in the main [Hilla Guides](https://vaadin.com/docs/next/hilla/guides.md) section: [Browser-Callable Services](https://vaadin.com/docs/next/hilla/guides/browser-callable-services.md), [Client-Side Data Caching](https://vaadin.com/docs/next/hilla/guides/client-caching.md), and [Client Middleware](https://vaadin.com/docs/next/hilla/guides/client-middleware.md). Event handling is documented for React views in [Event Handling](https://vaadin.com/docs/next/hilla/guides/event-handling.md), which also describes how the same events are bound in Lit templates. Upgrading and production deployment aren’t specific to Hilla, either: they’re documented for all of Vaadin in the [Upgrading Guide](https://vaadin.com/docs/next/upgrading.md) and in [Deploying to Production](https://vaadin.com/docs/next/flow/production.md).
