- **Real-Time Data**: Visualizations powered by the actual CSV data generated by the Premium Data Engine.
- **Secure Access**: Protected by HTTP Basic Auth.
- **Automated Updates**: Daily data collection for major AI/Tech companies (NVDA, MSFT, GOOGL, META, AAPL, TSLA, AMD).
## Local Development
1. **Clone the repository**:
```bash
git clone https://github.com/Nhughes09/replit.git
cd replit
```
2. **Install dependencies**:
```bash
pip install -r requirements.txt
```
3. **Set Environment Variables**:
You need a Finnhub API key.
```bash

```
4. **Run the App**:
```bash
uvicorn main:app --reload
```
Visit `http://localhost:8000`.

## Deployment on Hugging Face Spaces
This app is optimized for **Hugging Face Spaces** (Docker SDK).
### 1. Create a Space
1. Go to [huggingface.co/new-space](https://huggingface.co/new-space).
2. **Name**: `hheuristics-datasets` (or similar).
3. **SDK**: Select **Docker**.
4. **Template**: Select **Blank**.
5. **Space Hardware**: Free (CPU basic) is sufficient.
### 2. Connect Repository
You can either:
- **Sync with GitHub**: In the Space settings, connect this GitHub repository.
- **Direct Push**: Add the Space as a remote and push directly:
```bash
git remote add space https://huggingface.co/spaces/YOUR_USERNAME/SPACE_NAME
git push space main
```
### 3. Environment Variables
1. Go to your Space's **Settings** tab.
2. Scroll to **Variables and secrets**.
3. Add a **Secret**:
- Key: `FINNHUB_KEY`
- Value: Your Finnhub API Key.
### 4. Background Updates
The GitHub Action (`.github/workflows/daily_update.yml`) will still handle the daily data updates for free! It pushes the new data to GitHub, which will trigger a rebuild of your Space if you have connected them.
