[iOS] Cannot get data set by react-native's AsyncStorage

[ohnishiakira]

Current behavior

• On iOS, data (set by react-native core's AsyncStorage) cannot be accessed from this library's AsyncStorage.

Expected behavior

• Data can be accessed from both AsyncStorage.

Repro steps

• react-native init Sample --version 0.59.0
• yarn add @react-native-community/async-storage@1.2.1
• Use AsyncStorage in react-native and set data using AsyncStorage.setItem
• then Use AsyncStorage in @react-native-community/async-storage and get data using AsyncStorage.getItem

Environment

• Async Storage version: 1.2.1
• React-Native version: 0.59.0
• Platform tested: iOS
• Logs/Error that are relevant:

I create sample counter app using this App.js.

Here is desktop recording and operation logs.

1. start app. Currently using react-native's AsyncStorage ( count is 0 )
2. tap "increment" button 3 times ( count is 3 )
3. move to text editor and update App.js to using react-native-community/async-storage's AsyncStorage
4. reload app ( count backs to 0! )
5. tap "increment" button 4 times ( count is 4 )
6. move to text editor and update App.js to using react-native's AsyncStorage again
7. reload app ( count is 3 )

Hi @ohnishiakira , thanks for your input!

I believe this is because we've changed the name of a directory, where data is being saved.

This is our current name

react-native version

I cannot test it right now, but I'd like to see if it's the case.

@krizzu , I think this bug is very serious. Can you release new version soon?

[krizzu]

Hey @thientnc-ibl

Sure, but first, we have to discuss a way to add backward compatibility - maybe add a feature that allows different db/directory name.

What is the reason for the directory name change? I guess everyone who migrates from React Native's AsyncStorage expects the old data to be accessible, so shouldn't the default name of the directory be the same as before?

[krizzu]

That must have been the whirlwind of changes I did while detaching from RN Core.
I'm happy to revert it back, merge and release it, then think about adding a feature to change it in the future.

Let me know if anyone would like to work on it or should I do it.

Thanks.
