Redirecting on login

Here, things will get a bit more tricky. First, we'll do some preparation.

Inside our LoginContainer, when it comes to our signup and login methods, we currently just console.log out the result in our then statement. In other words, we don't actually do anything once our user logs in:

signup() {
  firebase.auth().createUserWithEmailAndPassword(this.state.email, this.state.password)
    .then(res => {
console.log(res);
    }).catch(error => {
      console.log(error);
      this.setState({ error: 'Error signing up.' });
    })
}

Let's change this bit (in both signup and login) to call another method, onLogin:

login() {
  firebase.auth().signInWithEmailAndPassword(this.state.email, this.state.password)
    .then(res => {
this.onLogin();
    }).catch((error) => {
      if (error.code === 'auth/user-not-found') {
        this.signup();
      } else {
        this.setState({ error: 'Error logging in.' });
      }
    });
}

Then, we can define our onLogin method:
