Is this tutorials some sort of series? Because I don't find Laravel code here.
If yes, then there is also validation part in the server I guess.

About global state (Vuex related), can I ask your opinion about storing info and token at the global states? Some people say that storing it in global states (Vuex or maybe local storage) can be attack-factor for doing XSS

Last thing, many people that are new to state management easily confused and sometimes misunderstood what it's for (sometimes they use it like Service Pattern in OOP paradigm). Maybe adding some diagram and illustration can bring more value to your reader :)
