If you don't want to polyfill the whole Promise API, [redux-storage-engine-localstoragefakepromise][] might be a possible solution for you. # A fork of [redux-storage-engine-localstorage](https://github.com/michaelcontento/redux-storage-engine-localstorage) The original author of the package [redux-storage-engine-localstorage](https://github.com/michaelcontento/redux-storage-engine-localstorage) has decided to deprecate the project and no longer maintained.
