title: Fetching global api data in nuxt
body: <p>I'm starting Nuxt project and I have to fetch basic data from my backend.
  for example language dictionary or some data for leftbar and etc.
  in Vue I can just call everything I need in App.vue and save it in vuex and then use whenever I want, but with Nuxt every page is different and I'm curious where should i call this global data api calls.
  I'm guessing I have to create middleware and call actions if data is not loaded already or there is better solution?</p>
