firebase.auth().createUserWithEmailAndPassword Undefined is not a function

Question

I am following the firebase documentation on user management

var firebase = require(\'firebase\');

// Initialize Firebase
firebase.initializeApp({
    servi         


        

Answer 1

Could this be because you defined the error as "err", but under errorMessage, "error.message" was the code? Not quite sure, but try this and see if it fixes:

var firebase = require('firebase');

// Initialize Firebase
firebase.initializeApp({
    serviceAccount: "./.json",
    databaseURL: "https://.firebaseio.com"
});

router.get('/create', function(req, res){
    var email = req.email;
    var password = req.password;
    firebase.auth().createUserWithEmailAndPassword(email, password).catch(function(error){ 
        var errorCode = error.code;
        var errorMessage = error.message;
        console.log("ERROR");
        console.log(errorCode, errorMessage);
    });
});
