When an app has network connectivity, mobile users process a case by performing steps, and the app runs various postprocessing actions on the server. When the app is in offline mode, the app queues these actions and runs them on the server during the subsequent data synchronization. However, your offline-enabled app can also run these actions with custom JavaScript activities or data transforms that run directly on the client. These JavaScript activities act as an offline substitute for the standard postprocessing of actions in online mode. If you use these custom activities in offline mode, and your business process ensures that the data from the client is always valid and final, you can skip the postprocessing on the server. This approach avoids duplicate processing of actions and saves server and app resources.
