Nuxtjs getting firestore data within asyncData

I'm trying to convert my VueJS app to NuxtJS to work with SSR. I'm stuck trying to get data loaded with asyncData. When I add my query to a 'mounted() {}' function it works fine but I can't get it to work with asyncData(){} so that I can use SSR.

Does anyone have any idea how to fix this.

My code: 

 <ul>
   <li v-for='province in provinces' v-bind:key="province.id"> {{province.name_nl}}</li>
      </ul>

  asyncData () {
    return { msg: 'Welcome to my  new app' }
    const moment = require("moment");
    var date = moment(new Date()).format("YYYY-MM-DD");
    let housesArray = []
    let provincesArray = []

    return firebase.firestore()
      .collection('provinces')
      .get()
      .then(querySnapshot => {
        querySnapshot.forEach(doc => {
        provincesArray.push(doc.data());
        });
        return {provinces: provincesArray}
      });
  },

Or is there another way I should be doing this? Keeping in mind that it does have to work with SSR.

PS: Yes this code is inside my pages folder, not the component, I know that's not allowed.

When using asyncDate() you can add the async and await keywords to wait for the response(s) before returning them.

How I solved it: 

 async asyncData () {
    const moment = require("moment");
    var date = moment(new Date()).format("YYYY-MM-DD");
    let housesArray = []
    let provincesArray = []

await firebase.firestore()
  .collection('provinces')
  .orderBy('name_nl')
  .get()
  .then(querySnapshot => {
    querySnapshot.forEach(doc => {
      provincesArray.push(doc.data());
    });
  });

await firebase.firestore()
  .collection("houses")
  .where("valid_until", ">", date)
  .get()
  .then(querySnapshot => {
    querySnapshot.forEach(doc => {
      housesArray.push(doc.data());
    });
  });

return {
  provinces: provincesArray,
  houses: housesArray
}
  },
