Building a reusable auth flow in React Native

A comprehensive guide on setting up a reusable authentication flow in React Native, this tutorial walks through creating a basic yet real-world auth system that can be easily implemented in future projects. It starts by outlining the necessary development environment, including Node.js, npm or Yarn, and the react-native-cli, and then guides users through creating a new React Native project named RNauthflow. The tutorial covers installing essential dependencies for navigation with React Navigation, setting up token storage using react-native-async-storage, and creating an authentication context with the React Context API. It explains how to implement auth actions using the useReducer and useMemo hooks, and how to integrate these into the app by wrapping the main component with an AuthProvider. Additionally, the tutorial details adding screens and navigation using React Navigation v5 to create a simple login and home screen flow. The guide concludes by suggesting deployment options with services like Firebase, Okta, and Auth0, and provides links to a GitHub repository for the complete code and a suggestion to use LogRocket for monitoring and improving React Native apps.
