+# caddy-spa
+
+**Configure Caddy to serve a Single Page Application**
+
+## Purpose
+
+This cube adds a reverse proxy configuration to Caddy for serving a Single Page Application (SPA) from a local backend server, with automatic HTTPS support.
+
+## What This Cube Does
+
+1. **Adds domain configuration to Caddyfile**
+   - Creates a site block for the specified domain
+   - Configures reverse proxy to forward traffic to local application
+   - Imports TLS configuration from the `caddy` cube
+
+2. **Configures reverse proxy**
+   - Proxies all requests to `localhost:{PORT}`
+   - Preserves headers and client information
+   - Handles WebSocket connections
+
+3. **Restarts Caddy service**
+   - Applies the new configuration immediately
+
+## Configuration
+
+### Parameters
+
+- **DOMAIN** (string, default: `''`)
+  - Domain name for the SPA application
+  - Example: `'myapp.example.com'`
+  - Must have DNS pointing to your server's IP
+
+- **PORT** (number, default: `5432`)
+  - Port number where the SPA will be served
+  - Your application should be listening on this port locally
+
+## Dependencies
+
+- **caddy** cube (implicitly required) - Must be installed first to provide the `tls_cert` snippet
+
+## What Gets Configured
+
+This cube adds the following to `/etc/caddy/Caddyfile`:
+
+```
+# BEGIN DOMAIN myapp.example.com
+myapp.example.com {
+    import tls_cert
+    reverse_proxy localhost:5432
+}
+# END myapp.example.com
+```
+
+## Use Cases
+
+**Deploy a React/Vue/Angular app**:
+```javascript
+exec('caddy-spa', {
+  DOMAIN: 'app.example.com',
+  PORT: 3000
+})
+```
+
+**Deploy multiple SPAs**:
+```javascript
+exec('caddy-spa', { DOMAIN: 'app1.example.com', PORT: 3000 })
+exec('caddy-spa', { DOMAIN: 'app2.example.com', PORT: 3001 })
+exec('caddy-spa', { DOMAIN: 'app3.example.com', PORT: 3002 })
+```
+
+## How It Works
+
+1. User visits `https://myapp.example.com`
+2. Caddy receives the request on port 443 (HTTPS)
+3. Caddy automatically handles SSL/TLS encryption
+4. Request is forwarded to `localhost:5432`
+5. Your application receives the request and returns a response
+6. Caddy sends the encrypted response back to the user
+
+## Prerequisites
+
+Before deploying this cube:
+
+1. **Install the caddy cube first**
+   - Provides the base Caddy installation and TLS configuration
+
+2. **Ensure your application is running**
+   - Your SPA backend should be listening on the specified PORT
+   - Example: `npm start` or `pm2 start app.js`
+
+3. **Configure DNS**
+   - Point your domain's A record to your server's IP address
+   - Wait for DNS propagation (can take a few minutes to hours)
+
+4. **Open firewall ports**
+   - Ensure ports 80 and 443 are open (for automatic HTTPS)
+   - `sudo ufw allow 80/tcp`
+   - `sudo ufw allow 443/tcp`
+
+## Post-Installation
+
+Verify the configuration:
+```bash
+sudo caddy validate --config /etc/caddy/Caddyfile
+```
+
+Check Caddy status:
+```bash
+sudo systemctl status caddy
+```
+
+View Caddy logs:
+```bash
+sudo journalctl -u caddy -f
+```
+
+## Common Issues
+
+**502 Bad Gateway**:
+- Your application isn't running on the specified PORT
+- Check: `netstat -tlnp | grep {PORT}`
+
+**Certificate errors**:
+- DNS not pointing to your server
+- Ports 80/443 blocked by firewall
+- Check Caddy logs: `sudo journalctl -u caddy -f`
+
+**Domain not resolving**:
+- DNS propagation not complete yet
+- Verify with: `dig +short myapp.example.com`
+
+## Notes
+
+- Caddy automatically obtains and renews Let's Encrypt certificates
+- The reverse proxy preserves the original client IP and headers
+- WebSocket connections are automatically supported
+- You can add multiple domains by running this cube multiple times with different parameters
