Which module is responsible for handling client-side data in Liferay?

The module responsible for handling client-side data in Liferay is Senna.js. This library is specifically designed to manage single-page application (SPA) experiences. It facilitates the dynamic loading of pages without requiring a full refresh by leveraging AJAX for data fetching. This allows for smoother user interactions and a more responsive interface, as it handles the client-side navigation and rendering of content seamlessly.

Senna.js plays a vital role in enhancing the performance of Liferay applications by minimizing page load times and providing a fluid user experience that is characteristic of modern web applications. By managing state and enabling fast transitions between different views, it effectively handles the client-side data layer, ensuring that data is fetched and displayed efficiently.

The other options pertain to different aspects of the Liferay ecosystem. Blade CLI is a command-line tool for creating and managing Liferay modules, while Portal Kernel pertains to the server-side logic of the framework. Theme Contributor is related to theming and how themes are applied within Liferay but does not primarily focus on client-side data handling.
