hackafy | Instagram clone built with React and Redux | User Interface library

You should normalize your state as explained in the redux docs. The key points:

1. You should keep your store as flat as possible
2. Try to reduce duplicate information => only set ids references instead of actual data

3. don't use arrays to store your data, because you will have to use find or filter a lot, instead use a map/object with the key as the access point to the actual object like this:

   comments: {comment_id1: {title: 'title', author:'author_id'}}

to get all comments, add a allComments array with only the ids like this
