Page Refresh and Unistore

When I refresh the page the state is lost with unistore which is similar to redux. React/Redux has middleware libs to persist the state. What are the options with unistore ? I found an interesting article on stackoverflow that talks about saving state to local storage. But things can get messy and the article also mentions about performance issues with frequent state changes.
