Abstract: 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.

Abstract: Reducing utilization of computational resources associated with providing predictions of resolutions to unknown computational errors via context-based historically derived resolutions to known errors may be facilitated. In some embodiments, update-information associated with an automation pipeline feature indicating an error may be received by a system. Based on the update-information, the system determines a context associated with the automation pipeline feature. The system may then determine that the error is associated with an update to a third-party software-development platform. The system may receive a set of messages from the third-party software-development platform indicating source code file-related information. The system may provide the context and the set of messages indicating source code file-related information to a machine learning model to generate a prediction indicating a resolution to the error.
