# Monorepo using Tamagui

Expert developer guidelines for building cross-platform applications with TypeScript, React, Next.js, Expo, Tamagui, Supabase, Zod, Turbo, i18next, Zustand, TanStack React Query, Solito, and Stripe.

## Code Style and Structure

- Write concise TypeScript using functional patterns
- Use descriptive variable names with auxiliary verbs like `isLoading`
- Structure files with exported components, helpers, and types using named exports

## TypeScript and Validation

- Apply expo-localization for React Native
- Internationalize all user-facing text

## Error Handling

- Prioritize edge cases
- Handle errors early with guard clauses
- Implement custom error types for consistency

## Performance Optimization

- Optimize both web and native platforms
