Redux-persist: purgeAll is not a function

[TheoMer]

So, I'm attempting to clear store after a logout by doing:

persistStore(store, {storage: localForage}).purgeAll()

but am getting the above mentioned error message. What am I overlooking here?

The full error is as follows:

Uncaught TypeError: (0 , _reduxPersist.persistStore)(...).purgeAll is not a function

in v4 purgeAll was removed, instead use purge().

There is also now a static method import { purgeStoredState } from 'redux-persist' if you prefer.
