Major differences between traditional UI and Theme Cosmos components

Updated on December 13, 2022
Applicable to Theme Cosmos applications

Theme Cosmos can support a hybrid architecture where most components retain the classic server-side rendering, but portal authoring components and list views use a React-based library. This approach produces a more efficient and dynamic interface, while leaving most Pega Platform functionalities unchanged.

The hybrid mode promotes ready-to-use low-maintenance solutions for portals and landing pages. Consequently, some classic Pega Platform components might work differently in this environment, or might not be supported. The following table lists some of the changes to the design process.

For more information, see Enabling hybrid mode.

ComponentChange in Theme Cosmos
AuthoringYou cannot edit Theme Cosmos portals and landing pages in Dev Studio.
Custom sections in portalsCustom sections that you insert manually into the portal harness might not work correctly in a Theme Cosmos environment. Best practice is to use the default sections, such as PortalNavigation for navigation, and edit them in the App Studio Channels menu.
Editable data pagesThe application deletes the pages at the end of a requestor cycle.
Full case viewIf you use App Studio to build new case types in existing applications, the end-user experience renders the full case view with the Cosmos React implementation of the Cosmos design system.
TablesTheme Cosmos offers enhanced performance for rendering, sorting, filtering, and grouping tabular data. This feature covers tables on landing pages, inside case pages, and tables in the Explore Data page.
