+# 🚀 Easypanel Deployment Guide (Nixpacks)
+
+## Overview
+
+This Astro website is configured for **automatic deployment on Easypanel** using **Nixpacks**.
+
+---
+
+## ✅ Auto-Detection
+
+Easypanel will automatically detect this as a Node.js project and use Nixpacks to build it.
+
+**No Dockerfile required!**
+
+---
+
+## 📋 Configuration
+
+### Easypanel Settings:
+
+1. **Project Name:** `dealplustech-astro`
+2. **Service Name:** `dealplustech-website`
+3. **Build Type:** `Nixpacks` (auto-detected)
+4. **Source:** Git repository
+5. **Branch:** `main`
+6. **Port:** `4321` (or use `$PORT` env variable)
+7. **Auto-Deploy:** ✅ Enabled
+
+---
+
+## 🔐 Environment Variables
+
+Set these in Easypanel → Settings → Environment:
+
+```bash
+# Database (SQLite file - Nixpacks will persist this)
+ASTRO_DB_REMOTE_URL=file:/data/consent.db
+
+# Admin Dashboard
+ADMIN_PASSWORD=your-secure-password-here
+
+# Umami Analytics (optional)
+PUBLIC_UMAMI_WEBSITE_ID=your-website-id
+PUBLIC_UMAMI_DOMAIN=https://analytics.moreminimore.com
+
+# Site URL
+PUBLIC_SITE_URL=https://your-domain.com
+```
+
+**⚠️ IMPORTANT:** Change `ADMIN_PASSWORD` from the default!
+
+---
+
+## 🗄️ Database Persistence
+
+The consent logging database needs persistent storage.
+
+### Option A: Volume Mount (Recommended)
+
+1. In Easypanel, go to Service → Volumes
+2. Add a new volume:
+   - **Path:** `/data`
+   - **Size:** `1 GB` (minimum)
+3. Set environment variable:
+   ```bash
+   ASTRO_DB_REMOTE_URL=file:/data/consent.db
+   ```
+
+### Option B: Turso (Production)
+
+For managed database:
+
+1. Create account at https://turso.tech
+2. Create database
+3. Get connection URL
+4. Set environment:
+   ```bash
+   ASTRO_DB_REMOTE_URL=libsql://your-db.turso.io
+   ASTRO_DB_APP_TOKEN=your-token
+   ```
+
+---
+
+## 🔄 Deployment Workflow
+
+### Automatic (Git Push):
+
+1. **Make changes locally**
+   ```bash
+   # Edit files
+   npm run build  # Test locally
+   git add .
+   git commit -m "Update content"
+   git push origin main
+   ```
+
+2. **Easypanel auto-deploys:**
+   - Detects push to `main`
+   - Runs Nixpacks build
+   - Deploys new version
+   - Health checks pass
+   - Traffic switches
+
+3. **Verify:**
+   - Check Easypanel dashboard
+   - Visit website URL
+   - Test cookie consent
+
+### Manual (Force Deploy):
+
+1. Go to Service in Easypanel
+2. Click "Deploy"
+3. Select latest commit
+4. Deploy
+
+---
+
+## 📊 Monitoring
+
+### Health Check
+
+Nixpacks will automatically health check the service.
+
+**Endpoint:** `http://localhost:4321/`  
+**Expected:** Status 200 OK
+

+
+## 🔐 Security Checklist
+
+- [ ] Change `ADMIN_PASSWORD` from default
+- [ ] Enable HTTPS (Easypanel provides SSL automatically)
+- [ ] Set up firewall rules (if needed)
+- [ ] Configure database persistence
+- [ ] Regular backups of consent logs
+

+
+## 🐛 Troubleshooting
+
+### Build Fails
+
+**Check:**
+1. `npm run build` works locally
+2. `package.json` scripts are correct
+3. All dependencies installed
+4. Node version is 20.x
+
+**Fix:**
+```bash
+npm install
+npm run build
+git push origin main
+```
+
+### Database Errors
+
+**Check:**
+1. Volume is mounted at `/data`
+2. Environment variable `ASTRO_DB_REMOTE_URL` is set
+3. Database file has write permissions
+
+**Fix:**
+```bash
+# In Easypanel:
+# 1. Add volume at /data
+# 2. Set ASTRO_DB_REMOTE_URL=file:/data/consent.db
+# 3. Redeploy
+```
+
+### Cookie Consent Not Working
+
+**Check:**
+1. CookieConsentBanner component is imported
+2. BASE_LAYOUT includes the component
+3. No console errors
+
+**Fix:**
+```bash
+# Verify component is included in layout
+# Check browser console for errors
+# Clear cache and reload
+```
+
+### Admin Dashboard 404
+
+**Check:**
+1. Route is `/admin/consent-logs`
+2. Service is running
+3. No build errors
+
+**Fix:**
+```bash
+# Access: https://your-domain.com/admin/consent-logs
+# Login with ADMIN_PASSWORD
+# Check server logs for errors
+```
+

+
+## 📈 Performance Optimization
+
+### Recommended Resources:
+
+- **CPU:** `0.5` core (minimum)
+- **Memory:** `512 MB` (minimum)
+- **Disk:** `1 GB` for database
+
+### Caching:
+
+Nixpacks automatically caches:
+- `node_modules/`
+- Build output
+
+### CDN (Optional):
+
+For better performance, add Cloudflare:
+1. Point DNS to Easypanel
+2. Enable Cloudflare proxy
+3. Configure caching rules
