Publication number: 20250141978Abstract: The techniques disclosed herein provide a synchronization engine that operates in conjunction with a service worker to dynamically store and update a working set of user data and single page application (SPA) resources from a network server to a user device. The working set can be hosted across several domains and identified by association with a user account. Accordingly, the synchronization engine retrieves the working set from the network server to enable offline execution of the single page applications. As such, subsequent requests for interacting with a single page application are then serviced by the synchronization engine using the working set retrieved from the network server. For instance, the service worker can bind user data to the application resources to enable progressive rendering through an application controller using locally available resources. In this way, the disclosed system provides a consistent user experience irrespective of network connectivity.Type: ApplicationFiled: October 25, 2023Publication date: May 1, 2025Inventors: Aninda RAY, Andrew James KOLTZ, Dennis Joel David MYREN, Naman KANAKIYA, Roger Allen LUEDER, Steven BAILEY, John FAN, Edgar HERNANDEZ GONZALEZ
