Process Application Frontend
The process application frontend is implementing the user task forms and business object views for the example application. It is built as a typical Angular Single Page Application (SPA) and provides views for both user tasks and the business objects. It communicates with process application backend via REST API, defined in the latter.
The user primarily interacts with the process platform which seamlessly integrates with the process applications. Usually, it provides integration points for user-task embedding / UI-composition. Unfortunately, this topic strongly depends on the frontend technology and is not a subject we want to demonstrate in this example. For simplicity, we built a very simple example, skipping the UI composition / integration entirely.
The navigation between the process platform and process application is just as simple as a full page navigation of a hyperlink.
