Wipe AsyncStorage in react native

I notice that I am wasting a certain amount of time debugging redux actions that I am persisting to AsyncStorage in react-native thanks to redux-persist. Sometimes I'd just like to wipe AsyncStorage to save some development time and try with fresh data.

EDIT: Best case the solution should work on simulators and real devices, iOS and Android. Maybe there are different work arounds for different platforms.

Thanks

Try using clear() function which erases all AsyncStorage for all clients, libraries, etc

clearAsyncStorage = async() => {
    AsyncStorage.clear();
}

This function can be applied anywhere on the code base to clear AsyncStorage. For example, here is how it can be called on a <Button> component.

<Button onPress={this.clearAsyncStorage}>
  <Text>Clear Async Storage</Text>
</Button>

You can clear AsyncStorage easily without touching your source code. Using react native debugger; and in the devtools console type

$reactNative.AsyncStorage.clear();

or to call it in RN's normal debugger with clear() you can put this in...

if (__DEV__) {
   global.clear = () => {
     AsyncStorage.clear().then(() => console.log('Cleared'))
   }
}

IMHO, all the answers referring to AsyncStorage.clear() are wrong, since, as the documentation say:

> Erases all AsyncStorage for all clients, libraries, etc. You probably > don't want to call this; use removeItem or multiRemove to clear only > your app's keys.

The correct answer may be found here:

> Here is a simple way of doing it:

clearAllData() {
    AsyncStorage.getAllKeys()
        .then(keys => AsyncStorage.multiRemove(keys))
        .then(() => alert('success'));
}

redux-persist comes with a purge() callback. You can call that in a debug menu somewhere if you choose.

Working with AsyncStorage threw a Reference Error on my side :

ReferenceError: AsyncStorage is not defined

I finally found in the React Native Debuguer documentation a mention about

> $reactNative.*

(For RN >= 0.56)

Which led mean to this snippet to wipe out all of my local storage :

clearAllData = () => {
    $reactNative.AsyncStorage.getAllKeys()
        .then(keys => $reactNative.AsyncStorage.multiRemove(keys))
        .then(() => alert('success'));
}

Then just clearAllData();
