# HFStudio - Quick Start Guide
## π Running Locally for Development
### Prerequisites
- Node.js 18+ and npm
- Python 3.8+
### Option 1: Quick Start (Recommended)
```bash
# Run both frontend and backend
./run_dev.sh
```
This will:
- Start the backend API server on http://localhost:11110
- Start the frontend dev server on http://localhost:11111
- Install dependencies automatically
### Option 2: Manual Setup
#### Terminal 1 - Backend
```bash
cd backend
# Install dependencies
pip install -r requirements.txt
# Run the server
python -m hfstudio.cli --dev
# Or install as package and run
pip install -e .
hfstudio --dev
```
Backend will run on http://localhost:11110
- API docs: http://localhost:11110/docs
- ReDoc: http://localhost:11110/redoc
#### Terminal 2 - Frontend
```bash
cd frontend
# Install dependencies
npm install
# Run dev server
npm run dev
```
Frontend will run on http://localhost:11111
## π Project Structure
```
hfstudio/
βββ frontend/ # Svelte UI (port 11111)
β βββ src/
β βββ routes/ # Page components
β βββ app.css # Tailwind styles
βββ backend/ # Python API (port 11110)
β βββ hfstudio/
β βββ server.py # FastAPI server
β βββ cli.py # CLI interface
βββ run_dev.sh # Dev startup script
```
## π¨ UI Features
- **Text Input**: Large textarea for text-to-speech input
- **Voice Selection**: Choose from available voices
- **Model Selection**: Switch between TTS models
- **Parameter Controls**: Adjust speed, stability, similarity
- **Mode Toggle**: Switch between API and Local execution
- **Audio Player**: Play and download generated speech
## π§ Development Tips
### Frontend Changes
- Edit files in `frontend/src/`
- Hot reload is enabled - changes appear instantly
- Tailwind classes are available
### Backend Changes
- Edit files in `backend/hfstudio/`
- With `--dev` flag, server auto-reloads on changes
- Test API endpoints at http://localhost:11110/docs
### Adding New Features
1. Frontend components go in `frontend/src/lib/components/`
2. API endpoints go in `backend/hfstudio/server.py`
3. TTS models will go in `backend/hfstudio/models/`
## π Troubleshooting
### Port Already in Use
```bash
# Change frontend port
cd frontend
npm run dev -- --port 11112
# Change backend port
cd backend
python -m hfstudio.cli --port 11112
```
### Missing Dependencies
```bash
# Frontend
cd frontend && npm install
# Backend
cd backend && pip install -r requirements.txt
```
### CORS Issues
Make sure both servers are running and check the CORS configuration in `backend/hfstudio/server.py` |
