Is module 'localStorage' required or can 'index.js' be used?

Instead of localStorage.js I used index.js to simplify the syntax for reading/write to store. This also because I only require 1 localStorage module.

Seems to work fine in most scenario

Store is properly initialized with state values
For writing the store I had to add mutations in 'index.js'. Is this required? ...It was not mentioned in the ReadMe

Only problem is that after refreshing the value is not initialized from LocalStorage.

Is this because a module with a name 'localStorage' must be used?
