creating a basic react redux application

I have a partly finished react application, but it needs redux to get data from the backend. It is basicly something reddit like. you have messages(posts) and reactions. when you land on the homepage it should get all the messages from the backend and show it with infinite scroll or pagination. You can upvote and downvote messages and when you click on a message you get redirected to another page with that message and the reactions on that message. when you add a message you get a token back that allows you to edit your reaction. The backend is done, the react frontend has already been worked. most of the work that needs to be done is using react to get data from the api.
