firestoreをasyncを使って取得する

asyncを使わないパターン

const functions = require('firebase-functions');
const admin = require('firebase-admin');
admin.initializeApp();
exports.db = functions
  .region('asia-northeast1')
  .https.onRequest((request, response) => {
  admin.firestore().collection('scores')
        .orderBy('maxKanaSpeed', 'desc')
        .limit(50)
        .get()
        .then((snapshot) =>
      {
        var scores = snapshot.docs.map(x => x.data());
        var json = JSON.stringify(scores);
        response.send("json" + json);
  });
});
