Synchronize offline events when user is online

Description

As soon as the connection to the OpenLMIS server is re-established, the application should attempt to synchronize the offline events it has with the server. The stock events should be sent synchronously in the same order they were created offline.

Questions:
Do we synchronize events for all users or just the user who is logged in?

  • We should synchronize just for the user who is logged in

Acceptance criteria:

  • When the user is online, their offline pending events are sent to the server

  • The events are sent in the same order they were created in the offline mode

  • The synchronization is happening in the background - the user can interact with the site

  • Sent events are considered successful unless the server responds with an error

Tested with success

Verified cases:

  • When the user is online, their offline pending events are sent to the server

  • The events are sent in the same order they were created in the offline mode

  • The synchronization is happening in the background

  • The events are sent for proper user

  • The stock on hands table is updated after synchronization

  • After code refactoring, synchronization works fine and stock events are removed from Local Storage when they are sent properly

  • When I close the app during synchronization the events are sent

Verified on:

  • Ubuntu 20.04

  • Google Chrome Browser Version 85.0.4183.83

  • Firefox Version 80.0

one small issue, when I close the app during synchronization and I do it too fast the event is sent but still exists in the offline pending events table and in the header.
