How to use ReactJS to style branding? How to develop my custom branding locally? (Universal login)

We are looking for local development of auth0 branding pages, how you guys are solving this challenge? I tried to using auth0 branding templates update but it’s painful to use.

I saw an article about auth0 and storybooks but there is no example of local development - how I can re use my components from storybook with auth0?
