In this chapter, we developed several common functionalities present in most e-commerce apps, such as user login and registration, retrieving data from an API, purchase journeys, and payments.
We tied all the screens with a common app state managed through Redux, which makes this app scalable and easily maintainable.
With maintainability in mind, we added properties validation for all our components and screens. Moreover, we enforced standard code formatting and linting, using ESLint, so that the app is ready for various team members to align and develop comfortable new features or maintain the current ones.
Finally, we also added API mocking for the developers to work locally without needing a backend when building the mobile app.
