如何将EXPO应用程序连接到Google Firestore？

Question

I am trying to authenticate a user and also organize the users in my database by their uid and then have the data field be by email. The users are successfully being authenticated however nothing appears in my firestore database.

My firestore security rules are in test mode so there should be no issue with permissions. In my action dispatch, I am successfully getting the user from firebase with their uid, access token, and everything else. I believe the error must be some way I am trying to connect to the firestore.

In my app.js file I initialize firebase like this-

import firebase from 'firebase';
import '@firebase/firestore';

componentDidMount() {
    const firebaseConfig = {
      apiKey: 'xxxxxxxx',
      authDomain: 'xxxxxxxxx.firebaseapp.com',
      databaseURL: 'xxxxxxxx.firebaseio.com',
      projectId: 'xxxxxxxx',
      storageBucket: 'xxxxxxx.appspot.com',
      messagingSenderId: 'xxxxxxxxxxx',
      appId: 'xxxxxxxxxxxxxxxxxxxx'
    };
    firebase.initializeApp(firebaseConfig);
  }

Then this is how I am trying to make the call to put the user into the database-

firebase.auth().createUserWithEmailAndPassword(email, password)
   .then((user) =>
     dispatch({ type: USER_LOGIN_SUCCESS, payload: user });
     const dbRoot = firebase.firestore();
     dbRoot.collection('users').doc(user.user.uid).set({ email });
   });

Also at the top of that file, I am importing as follows

import firebase from 'firebase';
import '@firebase/firestore';

Again, these users are being successfully authenticated but they are not appearing in the firestore database.

You have to add a collection to the database and add data .

const dbRoot = firebase.firestore().collection('users');
...
addData() {
  dbRoot.add({
    user: user.user.uid,
    email : email,
    complete: true,
  });

OR

const dbRoot = firebase.firestore().collection('users');
...
 const defaultDoc = {
        email: email
      };

async addData() {
  await  dbRoot.doc(user.user.uid).set(defaultDoc);
}
