In my application using Ionic 4 with Firebase/AngularFire2, I authenticate users with the signinwithemeailandpassword() method. I need to verify if it's the first time a user is logging in after registering. Firebase provides the option to check this using isNewUser.
When a new account is created with createUserWithEmailAndPassword(), the value of isNewUser is set to true, which is expected. However, when logging in with signinwithemeailandpassword(), the value always returns false, regardless of whether it's the first login or not.
Here is the code for the login method:
async login(form: NgForm) {
// Validate the login form
if (form.invalid)
return this.statusMessage.message('Validation error!');
console.log(this.user);
try {
const results = await this._afAuth.auth.signInWithEmailAndPassword(this.user.email, this.user.password).then(
user => console.log(user.additionalUserInfo.isNewUser)
);
// console.log(results);
} catch (error) {
switch (error.code) {
case "auth/user-not-found":
this.statusMessage.message("Your email address is wrong! Please try again");
break;
case "auth/invalid-email":
this.statusMessage.message("You have entered an invalid email address");
break;
case "auth/wrong-password":
this.statusMessage.message('The password you entered is wrong');
break;
default:
console.dir(error);
this.statusMessage.message('Something went wrong! Please try again later');
break;
}
}
And here is the signup code:
async register(form: NgForm) {
// Check form validation
if (form.invalid) return this.statusMessage.message('Validation error!');
console.log(this.user);
try {
await this.afAuth.auth.createUserWithEmailAndPassword(this.user.email, this.user.password).then(
user => console.log(user)
);
} catch (error) {
this.statusMessage.message('Something went wrong! Please try again later.');
}
}
}
