Vue Router and Vuex

I have 2 questions. 1. How can I catch undefined routes and redirect to 404 page? 2. How I can use Vuex actions to get data from api? I know that vuex mutations must be sync and actions async. But I can get data with mutations and can use then promise. but can't in actions or I do anything mistake. Please give me beautiful example for that(component type). I use vuex in laravel mix in Laravel project. Thanks...
