Available Scripts

• npm run dev - Start development server (with env check)
• npm run build - Build for production
• npm run start - Start production server
• npm run lint - Run ESLint
• npm run typecheck - Run TypeScript type checking
• npm run db:apply - Apply database schema
• npm run db:seed - Seed sample data

Python Package

See python/README.md for details on the Python package for vector indexing and recommendations.

Quick Start (Python)

cd python

# Using Poetry
poetry install
poetry run python src/ingest.py
poetry run python src/recommend.py --query "climate change"

# Using pip/venv
python3 -m venv venv
source venv/bin/activate
pip install -r requirements.txt
python src/ingest.py
python src/recommend.py --query "climate change"

Database Schema

The database includes the following tables:

• users - User accounts and profiles
• bills - Congressional bills
• bill_summaries - AI-generated bill summaries
• bill_embeddings - Vector embeddings for similarity search (pgvector)
• endorsements - User bill endorsements
• saved_bills - User saved bills

See db/schema.sql for the complete schema.

API Routes

Bills

• GET /api/bills - Get paginated list of bills
• GET /api/bills/[billId] - Get a specific bill
• POST /api/bills/[billId]/summary - Generate AI summary for a bill

Endorsements

• GET /api/endorsements - Get user's endorsements
• POST /api/endorsements - Create an endorsement
• DELETE /api/endorsements - Delete an endorsement

Auth

• GET/POST /api/auth/[...nextauth] - NextAuth endpoints

Authentication

The app uses NextAuth.js with email (magic link) authentication.

Note: Email functionality requires SMTP configuration. For development, you can use a service like Mailtrap or Resend.

To configure email:

1. Add SMTP environment variables to .env:

   SMTP_HOST=smtp.example.com
   SMTP_PORT=587
   [email protected]
   SMTP_PASSWORD=your-password
   [email protected]
   

2. Alternatively, use a Supabase adapter for authentication (see lib/auth.ts for TODO comments).

Development

Environment Variable Check

The dev server automatically runs scripts/load-env-check.ts to verify environment variables and show which features are available.

Mock Mode

The app gracefully handles missing API keys and database connections by:

• Returning mock data when database is not configured
• Showing placeholder AI summaries when API keys are missing
• Using mock Congress.gov data when API key is not set

This allows development without full configuration, but you'll want to configure all services for production.

Deployment

Vercel (Recommended)

1. Push your code to GitHub
2. Import your repository in Vercel
3. Add environment variables in Vercel dashboard
4. Deploy

Other Platforms

The app can be deployed to any platform that supports Next.js:

• Netlify
• Railway
• AWS Amplify
• Docker (see Dockerfile example in TODO)

TODO

• Implement actual Congress.gov API integration
• Complete Supabase adapter for NextAuth
• Add email templates for magic links
• Implement vector similarity search in Python package
• Add user preference-based recommendations
• Add "contact representative" functionality
• Add bill tracking and notifications
• Add comprehensive error handling
• Add tests (unit, integration, e2e)
• Add Docker support
• Add CI/CD pipeline
