Last week, Peter introduced to me an application that we use in Tong Hin. Briefly describe about the code that used in this application, It is use a React Native component that implements a login view for an app using the OAuth 2.0 authorization framework. It allows users to log in with a provider, in this case, obtains an access token and an ID token that can be used to authenticate the user’s identity and access protected resources on behalf of the user.
It’s imports libraries such as AsyncStorage, react-native-paper, and react-native-app-auth to implement functionalities such as token storage, UI components, and OAuth 2.0 authorization. The AppContext is used to share data between components, and screens in the app.
Next, it’s also defines the configuration for the authorization provider that will be used for the OAuth 2.0 authorization. The provider’s issuer, client ID, redirect URL, and etc are specified, as well as the scopes that the app requires access to.
Finally, defines the default state of the authentication, which includes information such as whether the user has logged in, which provider was used, and the tokens obtained from the authorization process.
