# Coolify Migration Guide

This document outlines the changes made to prepare the Next.js wedding app for deployment on Coolify (self-hosted on Proxmox).

## ✅ Changes Completed

### 1. Next.js Configuration (`next.config.ts`)
- ✅ Already configured with `output: "standalone"` for Docker deployment
- ✅ No localhost-specific configurations found
- ✅ Compatible with Coolify's build process

### 2. Environment Variables Strategy

#### Updated Files:
- **`src/lib/env.ts`**: Added support for dual Supabase URLs
  - `SUPABASE_URL`: Server-side internal Docker URL (optional, falls back to `NEXT_PUBLIC_SUPABASE_URL`)
  - `NEXT_PUBLIC_SUPABASE_URL`: Client-side external URL (required)
  - New `ENV.SUPABASE.SERVER_URL` property that uses internal URL in production

#### Created Files:
- **`.env.example`**: Complete production environment variable template with documentation

### 3. Supabase Client Configuration

#### Updated Files:
- **`src/lib/supabase.ts`**:
  - `createSupabaseClient()`: Always uses `NEXT_PUBLIC_SUPABASE_URL` for browser/client-side
  - `createSupabaseAdminClient()`: Uses `ENV.SUPABASE.SERVER_URL` (internal Docker URL in production)

- **`src/lib/supabase-server.ts`**:
  - `createServerSupabaseClient()`: Uses `ENV.SUPABASE.SERVER_URL` for server components
  - `createRequestSupabaseClient()`: Uses `ENV.SUPABASE.SERVER_URL` for API routes

### 4. Database Connection (Prisma)
- ✅ `prisma/schema.prisma`: Already compatible with both local and Docker network connections
- ✅ `package.json`: Build scripts include `prisma generate` which runs during Docker build
- ✅ `postinstall` script ensures Prisma client is generated after `npm install`

### 5. Docker Optimization
- ✅ Created `.dockerignore` with proper exclusions
- ✅ Verified `package.json` scripts work in Docker environment
- ✅ Prisma client generation runs during build (`prisma generate` in build script)

### 6. Hardcoded URL Fixes
- ✅ Fixed `src/app/api/admin/guests/route.ts`: Now uses `ENV.APP_URL`
- ✅ Fixed `src/app/api/rsvp/submit/route.ts`: Now uses `ENV.APP_URL` (2 instances)
- ✅ Fixed `src/lib/api-client.ts`: Now uses `ENV.APP_URL` for server-side

### 7. Git Configuration
- ✅ Updated `.gitignore` to exclude `.env.production`

```

## 🔧 How Dual Supabase URLs Work

### Development (Local Mac)
- Uses `NEXT_PUBLIC_SUPABASE_URL` for both client and server
- `SUPABASE_URL` can be omitted (falls back to `NEXT_PUBLIC_SUPABASE_URL`)
- Example: `http://localhost:54321`

### Production (Coolify)
- **Client-side (Browser)**: Uses `NEXT_PUBLIC_SUPABASE_URL` → External URL via Cloudflare tunnel
  - Example: `https://supabase-api.themoyos.co.za`
  
- **Server-side (API Routes, Server Components)**: Uses `SUPABASE_URL` → Internal Docker network URL
  - Example: `http://supabase-kong-CONTAINER_ID:8000`
  - Falls back to `NEXT_PUBLIC_SUPABASE_URL` if `SUPABASE_URL` is not set

### Benefits
- **Performance**: Server-side calls use internal Docker network (faster, no external routing)
- **Security**: Service role key only used server-side (never exposed to browser)
- **Reliability**: Internal network calls don't depend on Cloudflare tunnel availability

## 🚀 Deployment Steps

### Before Deployment

1. **Get Container IDs from Coolify**:
   - Find your Supabase Kong container ID
   - Find your Supabase DB container ID
   - Update `SUPABASE_URL` and `DATABASE_URL` with actual container IDs

2. **Generate Secrets**:
   ```bash
   # Generate SESSION_SECRET
   openssl rand -base64 32
   
   # Generate CSRF_SECRET
   openssl rand -base64 32
   ```

3. **Verify Local Build**:
   ```bash
   cd app
   npm run build
   ```
   Ensure build succeeds without errors.

### In Coolify

1. **Create New Service**:
   - Source: Your Git repository
   - Build Command: `npm ci && npm run build`
   - Start Command: `npm start`
   - Port: `3000`

2. **Set Environment Variables**:
   - Copy all required variables from `.env.example`
   - Replace placeholders with actual values
   - **Important**: Set `SUPABASE_URL` with actual container ID

3. **Configure Networking**:
   - Ensure Next.js app can reach Supabase containers via Docker network
   - Verify container names match your `SUPABASE_URL` and `DATABASE_URL`

4. **Deploy**:
   - Coolify will run `npm ci`, `npm run build`, then `npm start`
   - Prisma client will be generated during build (`prisma generate` in build script)

## 🔍 Verification Checklist

After deployment, verify:

- [ ] Application starts without errors
- [ ] API routes respond correctly
- [ ] Supabase client-side calls work (check browser network tab)
- [ ] Supabase server-side calls work (check API route logs)
- [ ] Database connections work (Prisma queries succeed)
- [ ] No hardcoded localhost URLs in production logs
- [ ] Environment variables are loaded correctly

## 🐛 Troubleshooting

### Issue: "Supabase is not configured"
- **Solution**: Ensure `NEXT_PUBLIC_SUPABASE_URL` and `NEXT_PUBLIC_SUPABASE_ANON_KEY` are set

### Issue: Server-side Supabase calls fail
- **Solution**: Check `SUPABASE_URL` is set correctly with container ID
- **Solution**: Verify Docker network allows communication between containers

### Issue: Database connection fails
- **Solution**: Verify `DATABASE_URL` uses correct container ID and password
- **Solution**: Check Docker network connectivity

### Issue: Build fails with Prisma errors
- **Solution**: Ensure `DATABASE_URL` is set during build (Prisma needs it for introspection)
- **Solution**: Check `prisma generate` runs successfully in build script

## 📝 Notes

- **Local Development**: Still works with `.env.local` using `localhost` URLs
- **Backward Compatibility**: If `SUPABASE_URL` is not set, falls back to `NEXT_PUBLIC_SUPABASE_URL`
- **Test Files**: Hardcoded `localhost:3000` in test files is intentional and fine
- **Proxy/Geofence**: `src/proxy.ts` checks for localhost - this is intentional for development

## 🔄 Migration Summary

| Component | Before | After |
|-----------|--------|-------|
| Client Supabase | `NEXT_PUBLIC_SUPABASE_URL` | `NEXT_PUBLIC_SUPABASE_URL` (unchanged) |
| Server Supabase | `NEXT_PUBLIC_SUPABASE_URL` | `SUPABASE_URL` (internal Docker) or fallback |
| Database | `DATABASE_URL` (localhost) | `DATABASE_URL` (Docker network) |
| App URLs | Hardcoded localhost | `ENV.APP_URL` |
| Build Output | Standard | Standalone (Docker-ready) |

## ✨ Next Steps

1. Test the build locally: `npm run build`
2. Set up environment variables in Coolify
3. Deploy to Coolify
4. Verify all functionality works
5. Monitor logs for any issues
