How can I do a config to coop with Redux?

So, I`m working with React and I need to make a config.js file so it could be changed.
I have some template settings in this config. And when I change my template with Redux, I need my config to be completely changed with the Redux state so I could refresh it and have the same settings.

I had an idea about localStorage, but I dont think this is a good idea for business app.
