[Vuejs]-Vue – use vuex instead of eventbus for calculations with nested data & components

I think you have some problems with architecture. Main idea here is to have some container (smart) component, that is connedcted with store (vuex), and simple (stupid) components, that recieve data from props. Also you must divide your store into modules, so it’ll be easy to maintain. This approach will allows you to modify exactly pieces of data you want.
