# ComfyUI Rust Frontend

A native Rust frontend for ComfyUI-like AI image generation tool using egui.

## Features

- Node-based workflow editor
- Real-time preview pane
- Integration with backend API
- ROCm support through Rust bindings

## Architecture

This frontend is built with:
- `eframe` and `egui` for the UI framework
- `reqwest` for HTTP communication with the backend  
- `serde` for JSON serialization/deserialization

## Project Structure

```
src/
├── main.rs          # Main application entry point
├── node_editor.rs   # Node-based workflow editor implementation
├── node_panel.rs    # Panel for selecting and managing nodes
├── preview_pane.rs  # Preview pane for image results
└── api_client.rs    # Backend API communication layer
```

## Running the Application

1. Make sure you have Rust installed (`rustup` or `curl https://sh.rustup.org/rustup.sh -sSf | sh`)
2. Start the backend server:
   ```bash
   cd ../backend && cargo run
   ```
3. In another terminal, run the frontend:
   ```bash
   cd rust-frontend && cargo run
   ```

## Building

To build for release:
```bash
cd rust-frontend && cargo build --release
```

The executable will be located at `target/release/comfyui-rust-frontend`.

## Integration with Backend

This frontend communicates with the backend through HTTP API endpoints. The API client handles:

- Fetching available node types from `/nodes`
- Executing workflows via POST to `/execute` 
- Getting execution results and preview images

The backend must be running on `http://localhost:8080` by default, but this can be configured in `src/main.rs`.
