After everything is set on Firebase end, let's create our Login and Sign Up screens for our instagramClone application. Let's reuse our API and Firebase service from the whatsappClone app, but we will leave only Firebase authentication in our API service for now. In a Firebase service, we will need to change the configuration, which we've already learned how to obtain from the Firebase console.

Our config/routes.js file will now look like this:

import Login from '../screens/Login';
import Signup from '../screens/Signup';
import Home from '../screens/Home';
const routes = {
 login: { screen: Login },
 signup: { screen: SignUp },
 home: { screen: Home }
 }
export default routes;
