+# Subdomain Support Implementation
+
+This implementation adds subdomain support to the Neploy application deployment platform, allowing applications to be accessed via subdomains instead of only path-based routing.
+
+## Features Added
+
+### 1. Backend Changes
+
+- **Enhanced Gateway Model**: Added `Subdomain` and `EndpointType` fields to support both routing types
+- **Flexible Deployment**: Modified application deployment to accept endpoint type and domain configuration
+- **Smart Router**: Updated gateway router to handle both subdomain and path-based routing
+- **Service Layer**: Enhanced gateway service with subdomain creation and management
+
+### 2. Frontend Changes
+
+- **Configuration UI**: Added endpoint type selection to application deployment form
+- **Domain Configuration**: Added domain input field for subdomain routing
+- **Enhanced Gateway Table**: Updated to show endpoint type and appropriate URL format
+- **Type Safety**: Added proper TypeScript types for subdomain configuration
+
+## Usage
+
+### Path-based Routing (Default)
+- **URL Pattern**: `domain.com/appname`
+- **Configuration**: Select "Path-based" in deployment form
+- **Example**: `localhost/myapp` or `company.com/api`
+
+### Subdomain Routing (New)
+- **URL Pattern**: `appname.domain.com`
+- **Configuration**: Select "Subdomain" in deployment form and specify domain
+- **Example**: `myapp.localhost` or `api.company.com`
+
+## Technical Implementation
+
+### Gateway Model
+```go
+type Gateway struct {
+    Domain        string `json:"domain"`
+    Subdomain     string `json:"subdomain"`
+    Path          string `json:"path"`
+    EndpointType  string `json:"endpointType"` // "subdomain" or "path"
+    // ... other fields
+}
+```
+
+### Route Matching Logic
+- **Subdomain**: Matches `Host` header against `subdomain.domain`
+- **Path**: Matches URL path prefix against configured path
+
+### Database Schema
+The existing database already supported subdomains with:
+- `subdomain` column for subdomain value
+- `endpoint_type` column with constraint `('subdomain', 'path')`
+- Unique constraints for both subdomain and path routing
+
+## Benefits
+
+1. **Flexibility**: Companies can choose their preferred routing method
+2. **Clean URLs**: Subdomain routing provides cleaner, more professional URLs
+3. **Separation**: Better logical separation of applications
+4. **Backward Compatibility**: Existing path-based deployments continue to work
+
+## Example Deployment Flow
+
+1. User deploys an application called "blog"
+2. Selects "Subdomain" endpoint type
+3. Specifies domain as "company.com"
+4. Application becomes accessible at `blog.company.com`
+5. Gateway table shows endpoint type and full URL
+
+## Testing
+
+Basic tests have been added to verify:
+- Route key generation for both types
+- Subdomain and path matching logic
+- Route validation
+
+Run tests with: `go test ./pkg/gateway -v`
