My index.js renders every time and I don't want this.

I don't know what happens, but every time I press a button on my sidebar my index.js renders

It is difficult to answer this question without seeing some source code, but if I were you I would look into optimizing with useMemo or useCallback.

It is also possible that you can use useEffect with an array dependency, but like I said, without seeing some source code, it is difficult to give better advice.

Take a look at https://reactjs.org/docs/hooks-reference.html and read useEffect, useMemo and useCallback.
