Phase 2 - Web Application with Authentication
Status: Evolved into Phase 3
Overview
Phase 2 was the web-based version of the Todo application that added:
- Frontend (Next.js) and Backend (FastAPI) separation
- User authentication via Better Auth
- JWT token-based security
- Web UI for task management
What Happened
Phase 2 codebase evolved directly into Phase 3 when the AI-Native chatbot was added. The Phase 2 web application (backend + frontend) served as the foundation for the Phase 3 AI-powered system.
Current Location
The Phase 2 codebase (with Phase 3 AI enhancements) is now located in:
../phase-3/backend/- FastAPI backend with Better Auth../phase-3/frontend/- Next.js frontend with web UI
Phase 2 vs Phase 3
| Feature | Phase 2 | Phase 3 |

If you need a pure Phase 2 version (without AI features), you can:
- Check out the git commit before Phase 3 implementation
- Remove the chatbot endpoint from Phase 3 backend
- Remove the chat UI from Phase 3 frontend
