In designing the app, I designed it as “the app has one map”.
-
We decided to create a map of the initial state when the app is launched.
-
Subsequently, the following features were added
- At startup, it reads information from the server and loads the data, if any.
- Whenever there is a Map update, save it to the server.
-
Usually the loading time is instantaneous, so it wasn’t a problem.
-
But after 6 hours of accumulating many people’s drawings, it started to take a long time.
-
Editing the initial state map before loading is complete writes its contents to the server
solution
- The “app has one map” is incorrect.
- App has a maximum of one map” is appropriate.
- The initial state of the application is “Do you want to create a new map? Open existing map?” It should be
- The initial map is created only when you choose to create a new one.
- Those who opened the edit link directly chose “Open Existing Map” equivalent.
- In this case, the loading indicator should be displayed until the loading is completed and editing should not be allowed.
