Project Overview
AquaStack is a universal React monorepo that combines Next.js web applications, Expo mobile clients, and Convex backends with Better Auth security. The project demonstrates full-stack type safety and real-time capabilities across multiple platforms from a single codebase.
The architecture leverages shared packages for common types, UI components, and utilities while maintaining platform-specific optimizations. This approach maximizes code reuse and ensures consistent user experience across web and mobile applications.
Technical Architecture
Built with Turborepo for efficient monorepo management, the system features:
- Backend: Convex real-time database with Better Auth integration for secure authentication
- Web App: Next.js with App Router, Convex client, and Better Auth session management
- Mobile App: Expo Router with NativeWind styling, Zustand state management
- Shared Packages: Centralized types, UI components, and auth utilities
The system provides complete end-to-end type safety with generated types from Convex schemas flowing through to all client applications.
