expo-firebase-starter VS expo-firebase-authentication

npx create-expo-app (also tried react-app and react-native app) appname --template https://github.com/expo-community/expo-firebase-starter

If you want an alternative rather than a solution, I’m using https://github.com/expo-community/expo-firebase-starter in my expo app.

Another thing I maintain is an Expo Community project that integrates Firebase JS SDK in an Expo app. Since the Expo SDK's exponential growth in the past year with the awesome tooling, Developer Experience (DX), and support for native modules, I have some thoughts on what changes I'll be doing next year. Keep an eye on this GitHub repo.

Following that, create the /screens directory mkdir src/features/sign-in/screens and the "sign in" screen touch src/features/sign-in/screens/SignInScreen.js. The "sign in" screen re-uses the , extending it to optionally support a custom submit button text. Note that if any error occurs, it'll be rendered using the component (full source code), which simply uses the component from native-base.

To being with, create the /components directory by running mkdir -p src/components and the email and password form touch src/components/EmailAndPasswordForm.js. The full code for the component can be found in the Github repository, but I'll highlight some of the important bits here.

The goal of this series of blog posts, is to provide a simple example of how to setup Expo and Firebase with email and password based authentication. When done, this app will support sign up, sign in, sign out, email verification, and password reset. All the code for this series of blog posts is available on this Github repository. Let's jump right in.
