Fullstack entertainment app using React & Nodejs

One thing I would have liked to improve upon is better arrangement of the login and signup components. These components are very similar in that their logic is nearly identical. What I wanted to do was to use a higher order component to provide the shared logic and pass into it the information unique to each component. What I have now are separate login and signup components that are very similar, and that I am not satisfied with. What would be the best way to go about improving this?

There are definitely other things that can be improved as well. If you have any comments on my code or project I would like to hear them!
