Firebase User Profile Add Custom Fields

Question

Is it possible to add custom fields to the user profile table in Firebase?

Right now it looks like I can only add data to:

• "uid"
• "displayName"
• "photoURL"
• "email"
• "emailVerified"
• "phoneNumber"
• "isAnonymous"
• "tenantId"
• "providerData":
• "apiKey"
• "appName"
• "authDomain"
• "stsTokenManager"
• "redirectEventId"
• "lastLoginAt"
• "createdAt"

I would like to have the ability to add custom objects to the JSON string to contain all of the user data.

Quick example, where after I have registered a user, I add that user to a usersCollection and supply other field information as necessary.

In my firebase powered app, what I do is the following:

import app from 'firebase/app'
import 'firebase/auth'
import 'firebase/database'
import 'firebase/firestore'

const config = {
  apiKey: process.env.REACT_APP_API_KEY,
  authDomain: process.env.REACT_APP_AUTH_DOMAIN,
  databaseURL: process.env.REACT_APP_DATABASE_URL,
  projectId: process.env.REACT_APP_PROJECT_ID,
  storageBucket: process.env.REACT_APP_STORAGE_BUCKET,
  messagingSenderId: process.env.REACT_APP_MESSAGING_SENDER_ID 
}

class Firebase {
  constructor (props) {
    app.initializeApp(config)

    this.auth = app.auth()
    this.db = app.database()
    this.firestore = app.firestore()
  }

  signUpWithEmailAndPassword = (email, pw) => {
    this.auth.createUserWithEmailAndPassword(email, password)
    .then(registeredUser => {
      this.firestore.collection("usersCollection")
      .add({
        uid: registeredUser.user.uid,
        field: 'Info you want to get here',
        anotherField: 'Another Info...',
        ....
      })
    }
  }
}

Hope this helps.
