datafold 0.1.13

# ✅ DataFold Native macOS App - Setup Complete!

## 🎉 Implementation Summary

Your DataFold project has been successfully converted to run as a **native macOS application** using Tauri!

## 📦 What Was Created

### 1. New Files

- **`src/datafold_node/embedded_server.rs`** - Embeddable server module
- **`src/datafold_node/static-react/src-tauri/`** - Complete Tauri configuration
  - `src/lib.rs` - Tauri app logic with server integration
  - `src/main.rs` - App entry point
  - `Cargo.toml` - Tauri dependencies
  - `tauri.conf.json` - App configuration
  - `icons/` - App icons (pre-generated)

### 2. Build Scripts

- **`run_tauri_dev.sh`** - Development mode (with live reload)
- **`build_macos_app.sh`** - Production build script
- **`TAURI_NATIVE_APP.md`** - Complete documentation

### 3. Modified Files

- `src/datafold_node/mod.rs` - Added embedded_server module
- `src/datafold_node/static-react/package.json` - Added Tauri scripts
- `src/datafold_node/static-react/src-tauri/Cargo.toml` - Dependencies configured

## 🚀 How to Use

### Development Mode

```bash
./run_tauri_dev.sh
```

This will:
1. Build the React frontend
2. Compile the Tauri app
3. Start the DataFold server automatically on port 9001
4. Open a native macOS window

### Production Build

```bash
./build_macos_app.sh
```

Creates a distributable `.app` bundle at:
```
src/datafold_node/static-react/src-tauri/target/release/bundle/macos/DataFold.app
```

### Install the App

After building, copy to Applications:

```bash
cp -r src/datafold_node/static-react/src-tauri/target/release/bundle/macos/DataFold.app /Applications/
```

Then launch **DataFold** from your Applications folder!

## 💡 Key Features

### ✅ What Works Now

- **Native App Icon** in Dock and Applications
- **Embedded Server** starts automatically
- **Separate Data Directory** (`~/.datafold/data`)
- **Same React UI** as web version
- **All DataFold Features** work identically
- **Small Bundle Size** (~15-20MB)
- **Better Performance** than Electron
- **macOS Integration** (window management, etc.)

### 🎯 Tauri Commands Available

The app exposes these commands to the frontend (for future enhancements):

```javascript
// Get server status
const status = await invoke('get_server_status');
// Returns: { running: boolean, port: number, url: string }

// Open data directory in Finder
await invoke('open_data_directory');

// Get app version
const version = await invoke('get_app_version');
```

## 📁 Data Storage

The native app uses a **separate database** from development:

- **Development Server:** `fold_db/data/`
- **Native App:** `~/.datafold/data/`

This keeps your development and production data isolated.

## 🔧 Technical Details

### Dependencies Added

**Backend (Tauri Rust):**
- `tauri 2.9.2` - Native app framework
- `tauri-plugin-log 2` - Logging
- `tauri-plugin-shell 2` - Shell integration
- `tokio` - Async runtime
- `dirs 5.0` - Home directory detection

**Frontend (npm):**
- `@tauri-apps/cli` - Build tools
- `@tauri-apps/api` - Frontend API

### Configuration

**Window Settings** (`tauri.conf.json`):
```json
{
  "title": "DataFold - Personal Database",
  "width": 1400,
  "height": 900,
  "minWidth": 1000,
  "minHeight": 700,
  "url": "http://localhost:9001"
}
```

**Bundle Settings:**
```json
{
  "identifier": "ai.datafold.app",
  "category": "Developer Tool",
  "macOS": {
    "minimumSystemVersion": "10.13"
  }
}
```

## 🎨 Customization

### Change the Icon

Replace files in:
```
src/datafold_node/static-react/src-tauri/icons/
```

### Change Window Settings

Edit `src/datafold_node/static-react/src-tauri/tauri.conf.json`

### Change Server Port

Edit `src/datafold_node/static-react/src-tauri/src/lib.rs`:
```rust
let server_port = 9001; // Change this
```

## 🐛 Troubleshooting

### Build Errors

1. Clean and rebuild:
   ```bash
   cd src/datafold_node/static-react/src-tauri
   cargo clean
   cd ..
   rm -rf dist
   npm run build
   cargo build
   ```

### Port Already in Use

Kill processes on port 9001:
```bash
lsof -ti:9001 | xargs kill -9
```

### App Won't Open (Security)

First launch security prompt:
```bash
xattr -dr com.apple.quarantine /Applications/DataFold.app
```

Or: **System Preferences → Security & Privacy → Open Anyway**
