+# PyWebView Development Environment Setup
+
+## Overview
+
+This document describes the PyWebView + FastAPI development environment setup for the MT Music Player web migration.
+
+## Installation
+
+The following packages have been installed via `uv`:
+
+- **pywebview**: Native webview wrapper for displaying HTML content
+- **fastapi**: Modern web framework for building APIs
+- **uvicorn**: ASGI server for FastAPI
+
+```bash
+uv add pywebview fastapi uvicorn
+```
+
+## Test Files Created
+
+### 1. Basic PyWebView Test (`test_pywebview.py`)
+- Simple standalone PyWebView window test
+- Verifies PyWebView installation and functionality
+- Run with: `uv run python test_pywebview.py`
+
+### 2. FastAPI Server (`test_fastapi_server.py`)
+- Standalone FastAPI server with background thread support
+- Includes CORS middleware for development
+- Test endpoints at `/` and `/api/test`
+- Can run standalone: `uv run python test_fastapi_server.py`
+
+### 3. Integrated Example (`test_pywebview_fastapi.py`)
+- Combined PyWebView + FastAPI setup
+- FastAPI runs in background thread
+- PyWebView window loads FastAPI server content
+- Includes Python-JavaScript API bridge
+- Run with: `uv run python test_pywebview_fastapi.py`
+
+### 4. Server (`server.py`)
+- General-purpose server supporting both development and production modes
+- Environment-based configuration for flexible deployment
+- Optional hot-reload for development (when `HOT_RELOAD=True`)
+- File watcher for Python, HTML, CSS, JS changes (dev mode)
+- Debug mode controlled via `DEBUG` environment variable
+- Configurable port and host via environment variables
+- Run with: `uv run python server.py`
+
+## Key Features Implemented
+
+✅ **PyWebView Package Installed**: Native webview wrapper installed and working
+✅ **Basic Window Creation**: Can create and display PyWebView windows
+✅ **FastAPI Server**: Background thread server implementation
+✅ **Server Integration**: PyWebView loads content from localhost FastAPI
+✅ **Hot-Reload**: Development server with automatic browser refresh
+✅ **Modular Configuration**: Port and host configurable via environment variables
+✅ **Debug Mode**: Developer tools accessible (F12 in window)
+✅ **CORS Configuration**: Enabled for development flexibility
+✅ **API Bridge**: Python-JavaScript communication established
+
+## Architecture
+
+```
+┌─────────────────┐
+│ PyWebView │
+│ (Native Window)│
+└────────┬────────┘
+ │
+ │ HTTP
+ ▼
+┌─────────────────┐
+│ FastAPI │
+│ (Backend API) │
+└─────────────────┘
+```
+
+## Configuration
+
+The server uses `python-decouple` for environment-based configuration:
+
+### Core Settings
+- **SERVER_PORT**: Port number (default: 3000)
+- **SERVER_HOST**: Host address (default: 127.0.0.1)
+- **APP_TITLE**: Application title (default: "mt music player")
+
+### Mode Settings
+- **DEBUG**: Enable debug mode (default: False)
+- **HOT_RELOAD**: Enable file watcher and auto-reload (default: False)
+- **CORS_ENABLED**: Enable CORS middleware (defaults to DEBUG value)
+
+### Quick Setup
+
+For development:
+```bash
+cp .env.dev .env # Pre-configured for development
+```
+
+For production:
+```bash
+cp .env.example .env # Pre-configured for production
+```
+
+Or set directly:
+```bash
+DEBUG=True HOT_RELOAD=True uv run python server.py # Development
+DEBUG=False uv run python server.py # Production
+```
+
+## Development Workflow
+
+1. **Start Development Server**:
+ ```bash
+ uv run python server.py
+ ```
+
+2. **Access Application**:
+ - Window opens automatically
+ - FastAPI server at http://localhost:3000
+ - Developer tools with F12
+
+3. **Hot-Reload**:
+ - Edit any `.py`, `.html`, `.css`, or `.js` file
+ - Browser automatically reloads
+
+## Next Steps
+
+With this foundation in place, the next phases of the migration can proceed:
+
+1. **Zig Module Enhancement** (Task 23): Update scanning module for web architecture
+2. **FastAPI Backend** (Task 24): Build comprehensive API framework
+3. **Audio Streaming** (Task 25): Implement streaming service
+4. **HTMX Frontend** (Task 26-29): Create UI with HTMX and Alpine.js
+5. **Native Integration** (Task 31-32): File system and keyboard shortcuts
+
+## Testing
+
+Run all test files to verify setup:
+
+```bash
+# Test PyWebView alone
+uv run python test_pywebview.py
+
+# Test FastAPI server
+uv run python test_fastapi_server.py
+
+# Test integrated setup
+uv run python test_pywebview_fastapi.py
+
+# Run development server
+uv run python server.py
+```
+
+All components are working and ready for the web migration implementation.
