Setup

Prerequisites

• Python 3.11+
• Node.js 18+
• NeonDB account (free tier works)
• Google Cloud project with OAuth credentials
• Gemini API key
• Groq API key

1. Backend

cd backend
python -m venv .venv
source .venv/bin/activate
pip install -r requirements.txt

2. Frontend

cd frontend
npm install

3. Environment variables

Copy env.example to .env in the project root and fill in your keys. See the file for descriptions of each variable.

4. Database

Create a project on NeonDB, copy the connection string into NEON_DATABASE_URL in .env. Tables are auto-created on first startup, or you can run backend/app/schema.sql manually.

5. Google OAuth

In Google Cloud Console, create OAuth 2.0 credentials and add http://localhost:8000/auth/callback as an authorized redirect URI.

Running locally

Start both in separate terminals:

# Backend (from backend/)
uvicorn app.main:app --reload --port 8000

# Frontend (from frontend/)
npm run dev

Frontend runs at http://localhost:5173, backend at http://localhost:8000. The Vite dev server proxies /api and /auth requests to the backend.

API Endpoints

Interactive docs available at http://localhost:8000/docs when running.
