I asked myself: Why do I need Vuex? I did not find a good answer. Here is why I question the value of Vuex. I found this article:
https://blog.logrocket.com/vuex-why-we-need-spa-state-management/ Which does not really answer, why? It explains what Vuex does, but why can you not do that with a simple service? I forked that repo and re-wrote it without Vuex and with an ApplicationService that takes care of state management.
