App Architecture
Overview
This document outlines the architecture stack for the React Native app, providing a structured foundation for scalable, maintainable, and flexible development. The architecture includes frontend, backend, cloud services, AI/ML integration, and state management strategies. Additionally, it emphasizes modular design to facilitate future improvements and replacements.
| Component | Abstraction Layer Name | Purpose |
|---|---|---|
| Cloud Sync | useCloudStorage() | Allows switching between Firebase, Supabase, AWS S3 |
| ML Services | useAIService() | Enables integration with FastAPI or third-party AI APIs |
| Authentication | useAuth() | Decouples authentication logic from Firebase/Supabase |
| State Management | useAppState() | Ensures global state management consistency |
| Local Storage | useLocalStorage() | Provides offline support via SQLite/AsyncStorage |
1. Technology Stack
1.1 Frontend (React Native Mobile App)
- Framework: Ignite by Infinite Red
- UI Components: React Native Paper / Tailwind CSS
- Navigation: React Navigation
- State Management: Redux Toolkit / React Query
- Offline Storage: SQLite / AsyncStorage
- Data Visualization: Recharts / D3.js
- Authentication: OAuth2 / JWT / Supabase Auth
1.2 Backend & Data Processing
- Backend Framework: FastAPI (Primary API Framework) / Flask (Optional lightweight alternative)
- Database: PostgreSQL / TimescaleDB (for time-series data)
- Data Caching: Redis
- GraphQL / REST API: GraphQL (for flexible queries) / REST API (for performance-critical endpoints)
1.3 AI & Machine Learning Integration
- AI Frameworks: PyTorch / TensorFlow / Scikit-Learn
- API Interface for AI: FastAPI-based AI Service for model inference
- AI Cloud Services (Optional): OpenAI API / Hugging Face / AWS SageMaker
1.4 Cloud Infrastructure & Services
- Hosting: DigitalOcean / AWS / Google Cloud
- Cloud Storage: AWS S3 / Supabase Storage
- Authentication & User Management: Supabase Auth / OAuth2
- CI/CD Deployment: GitHub Actions / Docker
1.5 WordPress Plugin for Data Visualization
- Framework: React JS
- Charting Library: Recharts
- Data Fetching: WordPress REST API for retrieving stored analytics

Appendix B: Decision Process
B.1 Starter Kit Selection
| Starter Kit | Open Source? | AI/ML Ready? | Cloud Sync Flexibility? | Final Choice |
|---|---|---|---|---|
| Ignite by Infinite Red | ✅ Yes (MIT) | ❌ No | ⚠️ Firebase Focus | ✅ Best Choice |
| React Native Starter AI | ❌ No (Paid) | ✅ Yes | ⚠️ Limited | ❌ No (Paid) |
| Flatlogic React Native Starter | ❌ No (Paid) | ⚠️ Partial AI | ❌ Firebase-Only | ❌ No (Paid) |
| mcnamee/react-native-starter-kit | ✅ Yes (MIT) | ❌ No | ✅ Flexible | ✅ Backup Plan |
B.2 Cloud Synchronization Decision
| Cloud Provider | Pros | Cons | Final Choice? |
|---|---|---|---|
| Firebase | Easy Setup | Vendor Lock-in | ❌ No |
| Supabase | Open-Source, SQL | Newer, less proven | ✅ Yes |
| AWS S3 + API | Highly Scalable | Requires API work | ✅ Yes |
Appendix C: Future Expansion Considerations
- Explore on-device AI inference using TensorFlow.js or ML Kit for mobile AI capabilities.
- Implement WebSockets for real-time updates instead of periodic API polling.
- Consider GraphQL adoption for flexible API queries and performance improvements.
- Develop modular feature flags to enable/disable components based on user needs.
