## 🏗️ Architecture

- **Backend**: Django REST Framework (Python)
- **Frontend**: React + TypeScript + Material-UI
- **Search Engine**: ElasticSearch
- **Task Queue**: Celery + Redis
- **Audio Extraction**: yt-dlp + FFmpeg
- **Containerization**: Docker

## 📋 Prerequisites

- Docker & Docker Compose
- 2-4GB available RAM
- Dual-core CPU (quad-core recommended)
- Storage space for your audio library

## 🚀 Quick Start

### 1. Clone the Repository

```bash
git clone https://github.com/yourusername/soundwave.git
cd soundwave
```

### 2. Create Environment File

```bash
cp .env.example .env
# Edit .env if you want to change default credentials
# Default: admin / soundwave
```

### 3. Start the Application

```bash
docker compose up -d
```

That's it! The application will:
- Pull/build all necessary images
- Start ElasticSearch and Redis
- Start the SoundWave application
- Run database migrations automatically

**Access:** http://localhost:8889  
**Default credentials:** admin / soundwave

### First-Time Setup

The application automatically:
- Creates the admin user on first run
- Runs database migrations
- Collects static files
- Initializes the search index

Just wait ~30-60 seconds after `docker compose up -d` for services to be ready.

## 📖 Detailed Setup (Old Method)

Copy the example environment file and customize it:

```bash
cp .env.example .env
```

Edit `.env` with your preferred settings:

```env
SW_HOST=http://localhost:123456
SW_USERNAME=admin
SW_PASSWORD=your_secure_password
ELASTIC_PASSWORD=your_elastic_password
TZ=America/New_York
```

### 3. Start SoundWave

```bash
docker-compose up -d
```

### 4. Access the Application

Open your browser and navigate to:
```
http://localhost:123456
```

Login with the credentials you set in `.env`:
- **Username**: admin (or your SW_USERNAME)
- **Password**: soundwave (or your SW_PASSWORD)

## 🛠️ Development

### Backend Development

```bash
cd backend
python -m venv venv
source venv/bin/activate  # On Windows: venv\Scripts\activate
pip install -r requirements.txt
python manage.py migrate
python manage.py runserver
```

### Frontend Development

## 🔧 Configuration

### Environment Variables

| Variable | Description | Default |
|----------|-------------|---------|
| `SW_HOST` | Application URL | `http://localhost:123456` |
| `SW_USERNAME` | Initial admin username | `admin` |
| `SW_PASSWORD` | Initial admin password | `soundwave` |
| `ELASTIC_PASSWORD` | ElasticSearch password | Required |
| `REDIS_HOST` | Redis hostname | `soundwave-redis` |
| `TZ` | Timezone | `UTC` |
| `SW_AUTO_UPDATE_YTDLP` | Auto-update yt-dlp | `false` |

### Audio Quality

By default, SoundWave downloads the best available audio quality. You can configure this in the settings or via yt-dlp options in `task/tasks.py`.

## 🐛 Troubleshooting

### Container Won't Start

```bash
# Check logs
docker-compose logs soundwave

# Check ElasticSearch
docker-compose logs soundwave-es

# Restart services
docker-compose restart
```

### Download Failures

- Ensure yt-dlp is up to date: Set `SW_AUTO_UPDATE_YTDLP=true`
- Check FFmpeg is installed in the container
- Review download logs in the admin panel

### Port Already in Use

If port 123456 is in use, change it in `docker-compose.yml`:

```yaml
ports:
  - "YOUR_PORT:8000"
```
