# Node Text-to-Speech Starter
Text-to-speech demo using Deepgram's API with Node.js backend and web frontend.
## Prerequisites
- [Deepgram API Key](https://console.deepgram.com/signup?jump=keys) (sign up for free)
- Node.js 24+ and pnpm 10+
**Note:** This project uses strict supply chain security measures. npm and yarn will NOT work - pnpm 10.0.0+ is required. See [SECURITY.md](SECURITY.md) for details.
## Quick Start
1. **Install dependencies**
```bash
# Option 1: Use the helper script (recommended)
pnpm run install:all
# Option 2: Manual two-step install
pnpm install
cd frontend && pnpm install && cd ..
```
**Note:** Due to security settings (`ignore-scripts=true`), frontend dependencies must be installed separately. The `install:all` script handles both steps. See [SECURITY.md](SECURITY.md) for details.
2. **Set your API key**
Create a `.env` file:
```bash
DEEPGRAM_API_KEY=your_api_key_here
```
3. **Run the app**
**Development mode** (with hot reload):
```bash
pnpm dev
```
**Production mode** (build and serve):
```bash
pnpm build
pnpm start
```
### 🌐 Open the App
[http://localhost:3000](http://localhost:3000)
## Features
- Enter text to convert to audio
- Multiple model options
- View text-to-speech history
## How It Works
- **Backend** (`server.js`): Node.js/Express server implementing the `/tts/synthesize` endpoint
- **Frontend** (`frontend/`): Vite-powered web UI for audio upload and transcription display
- **API**: Integrates with [Deepgram's Speech-Text-to-Speech API](https://developers.deepgram.com/)
