React Native

• Use React following the React Guide
• Use TypeScript
• Prefer using core components and apis over writing bespoke components.

Tooling

• Start new projects with create-belt-app
• Use Expo
• Use Expo EAS for continuous deployment
• Use Expo Secure Store for storing sensitive data like auth and refresh tokens
• Use React Navigation for routing
• Use TanStack React Query as an API client for REST APIs
• Use Apollo Client as an API client for GraphQL APIs
• Use Redux Toolkit for global state
  • Avoid storing API data in a global store. Instead, use a dedicated API client.
• Use React Native Firebase for push notifications
• Use Sentry for error reporting
• Prefer RevenueCat for in-app payments
  • If RevenueCat pricing is not acceptable since it collects a percentage of revenue, use react-native-iap

Style

• Prefer using StyleSheets
• Prefer organized and composable styles
• Avoid designing for only one platform.
• Avoid designing for only one screen size.
• Prefer common mobile patterns and avoid non-standard patterns.

Testing

• Test using React Native Testing Library and Jest
