✅ Setup Complete - Local PostgreSQL Configuration

What Changed

1. Removed Supabase Configuration ❌

  • Removed all Supabase connection strings from .env
  • No more IPv6 connectivity issues
  • No cloud database dependencies for local development

2. Configured Local PostgreSQL ✅

  • Database: inflashield
  • Connection: postgresql://postgres:postgres@localhost:5432/inflashield
  • Automatic database creation on first run
  • All tables and schemas created automatically

3. Updated Project Structure ✅

New Files:

  • scripts/setup-db.js - Automatic database creation script
  • LOCAL_SETUP.md - Complete local development guide
  • SETUP_COMPLETE.md - This file

Modified Files:

  • .env - Local PostgreSQL configuration
  • drizzle.config.ts - Updated for local database
  • package.json - Added automatic setup scripts
  • README.md - Updated Quick Start guide
  • Moved auth.ts and auth.config.ts to src/ directory

4. Database Schema ✅

Schemas Created:

  • app - Application data
  • audit - Immutable audit logs

Tables Created:

  • app.users - User accounts
  • app.sessions - User sessions
  • app.hedge_signals - Hedge recommendations
  • app.orders - Trade orders
  • app.wallets - Connected wallets
  • app.notification_preferences - User settings
  • audit.audit_log - Audit trail

How to Use

Start Development Server

npm run dev

What happens:

  1. Checks if PostgreSQL is running
  2. Creates inflashield database if it doesn't exist
  3. Creates all required tables and schemas
  4. Starts Next.js development server at http://localhost:3000

Other Commands

# Manually setup database
npm run db:setup

# Push schema changes
npm run db:push

# Run migrations
npm run db:migrate

# Visual database browser
npm run db:studio

# Build for production
npm run build

For Production (Vercel)

Option 1: Vercel Postgres (Recommended)

  1. Deploy to Vercel
  2. In Vercel Dashboard: Storage → Create Database → Postgres
  3. Vercel automatically sets DATABASE_URL environment variable
  4. Done! No manual configuration needed

Option 2: External PostgreSQL

  1. Create PostgreSQL instance (AWS RDS, DigitalOcean, etc.)
  2. In Vercel Dashboard: Add environment variable:
    DATABASE_URL=postgresql://user:password@host:5432/inflashield
    
  3. Deploy

See docs/QUICK_DEPLOY.md for step-by-step Vercel deployment.


Database Connection Details

Local Development

Host: localhost
Port: 5432
Database: inflashield
User: postgres
Password: postgres

Production (Vercel Postgres)

Automatically configured by Vercel when you create a database in their dashboard.


Key Differences: Local vs Supabase

Feature Local PostgreSQL Supabase (Removed)
Setup Automatic Manual configuration
Connectivity Always works IPv6 issues
Cost Free Free tier limits
Management Local control Cloud managed
Deployment Use Vercel Postgres Required Supabase account

Verification Checklist

✅ PostgreSQL installed and running
✅ Database inflashield created
✅ All tables created in app schema
✅ Audit table created in audit schema
✅ Development server starts without errors
✅ API endpoints respond correctly
✅ No Supabase dependencies


Next Steps

  1. Development Ready - Run npm run dev to start coding
  2. 📖 Read Documentation - See LOCAL_SETUP.md for troubleshooting
  3. 🚀 Deploy to Production - Follow docs/QUICK_DEPLOY.md
  4. 🔑 Add API Keys - Configure external API keys in .env

Troubleshooting

Database connection fails

# Check if PostgreSQL is running
sudo systemctl status postgresql

# Start PostgreSQL
sudo systemctl start postgresql

Password authentication failed

# Reset password
sudo -u postgres psql -c "ALTER USER postgres WITH PASSWORD 'postgres';"

Port 3000 already in use

# Kill process on port 3000
lsof -i :3000
kill -9 <PID>

See LOCAL_SETUP.md for more troubleshooting tips.


Summary

Your InflaShield project is now configured to:

  • ✅ Run locally with PostgreSQL (no cloud dependencies)
  • ✅ Auto-create database and tables on first run
  • ✅ Deploy to Vercel with Vercel Postgres (managed cloud database)
  • ✅ Work without IPv6 connectivity issues
  • ✅ Have clean separation between local and production environments

Ready to code! 🚀
