Transactional autosave with local and remote lifecycles

Abstract:

A system performs autosave. The system receives, by a web browser of a client device, a user action performed by a user that interacts with a website corresponding to a server. The system determines a change record corresponding to the user action, queues the change record in a first queue to commit corresponding changes to local models, and queues the change record in a second queue that communicates with the server to persist the change record at the serve. The first queue may be an ordered persistence queue that maintains a history of change records for performing undo and redo operations in interacting with the website. The second queue may be an ordered queue where change records are processed one at a time and each change record is sent to the server only if a prior change record in the second queue has been successfully recorded on the server.
