Chat app that uses Firebase to handle messaging, with a very simple authentication process for Sign in and Sign up.

Run App

npm install
npm run start

# Press I to open iOS simulator
# Press A to open Android emulator

Decisions

• Use Expo for easier configurations, installing libraries with the correct versions, better debugging, easier building apk and ipa process, easier use of emulators/simulators, and many other benefits.
• use hooks and a Context to handle auth state.
• use Typescript, and linter + prettier configurations to improve the code quality, readeability and to avoid typing bugs.

Improvement areas

• Unit and E2E testing to be able to test the app without the UI. Using jest and Detox.
• add a profile screen
• maybe improve speed when fetching data
• show some image or text message if there are no users in the Chat List Screen
• add scrollview in case if there are many users
