Thanks… it’s working (Y)

import firebase from "firebase"
require("firebase/firestore");

// Initialize Firebase
var config = {
  apiKey: "XXXX",
  authDomain: "XXX.firebaseapp.com",
  databaseURL: "https://XXXX.firebaseio.com",
  projectId: "XXX",
  storageBucket: "XXX.appspot.com",
  messagingSenderId: "XXXX"
};
firebase.initializeApp(config);

var db = firebase.firestore();

.
.
.
.
  componentDidMount(){
    var db = firebase.firestore();
    var docRef = db.collection("users");
    const output = {};

    docRef.limit(50)
		.get()
		.then(querySnapshot => {
			querySnapshot.docs.map(function (documentSnapshot) {
				return (output[documentSnapshot.id] = documentSnapshot.data());
			});
      this.setState({dataSource: Object.entries(output)}) ;
      console.log("datasource:", this.state.dataSource );
		});
  }
