# TauPy
Build desktop apps with **Python + Rust**, and drop in React/Vite when you want. Fast reloads, native window controls, and a tiny API surface.
## Demo
🎯 **Focus Timer Demo** - a small demo application showcasing TauPy window APIs,
compact mode switching, and a React-based UI.
👉 https://github.com/S1avv/taupy-focus
## Why TauPy
- **Hybrid by design** - Python backend + Rust launcher; use Python widgets or a full React front-end.
- **Hot dev loop** - edit → window refreshes near-instantly, no page reload dance.
- **Native window API** - minimize/maximize/resize/drag, all routed through Python to the launcher.
- **Shipping ready** - `taupy build` bundles your front-end, rebuilds the launcher, and Nuitka-packages the backend.
## Code example (Python UI)
```python
from taupy import App, VStack, Text, Button, State
from taupy.events import Click
app = App("Hello TauPy", 800, 500)
msg = State("Hello, TauPy!")
@app.dispatcher.on_click("btn_hello")
async def hello(_: Click):
msg.set("Button clicked!")
@app.route("/")
def home():
return VStack(Text(msg), Button("Click me", id="btn_hello"))
if __name__ == "__main__":
import asyncio
asyncio.run(app.run(VStack(id="root")))
```
## Install
```bash
pip install taupy-framework
```
## Quick start (React front-end)
```bash
taupy new [app_name]
cd [app_name]
npm install
taupy dev
```
## Build
```bash
taupy build
```
Pipeline:
1) Build React/Vite (if present) → `target/dist`
2) `cargo build --release` for the launcher → `target/launcher`
3) Nuitka bundle backend → `target/app.exe`
## Performance snapshot (indicative)
| Scenario | TauPy (Python + Rust) | PyQt / PySide | Tkinter | Electron |
|--------|------------------------|---------------|----------|----------|
| Cold start (release build) | ~300–600 ms | ~900 ms – 1.8 s | ~500–900 ms | ~1.5 – 3 s |
| Hot reload (code → UI) | ~40–120 ms (WS diff) | Full widget refresh | Full redraw | ~200–500 ms |
| UI update (state → render) | ~10–40 ms | QWidget update | Full widget update | Virtual DOM diff |
| Bundle size | ~6–15 MB + dist | 40–80 MB | ~2–5 MB | 120+ MB |
| UI stack | HTML/CSS (WebView) | Native Qt | Native Tk | Chromium |
### Measurement conditions
> Measurements taken on Windows 11, Ryzen 7 5800X, NVMe SSD.
> Release builds, minimal "hello world" applications.
> Numbers are indicative and vary by project size and configuration.
## TauPy CLI
- `taupy dev` - run backend + external front-end (Vite) with hot reload.
- `taupy build` - build front-end, launcher, and Nuitka bundle into `target/`.
- `taupy new ` - scaffold a new TauPy project.
## Dev vs Prod (auto)
- Dev (`--dev`): external HTTP (Vite 5173), hot reload.
- Prod: serves bundled `dist/` on 8000. Override with `TAUPY_EXTERNAL_HTTP` / `TAUPY_HTTP_PORT`.
## 📘 Documentation

## Roadmap
- Cross-platform launcher (Linux/macOS)
- Native dialogs & notifications
- Packaging presets (single-file)
- Built-in icon set & theme presets
- DevTools/inspector mode
- Playground in browser
## Requirements
- Windows 64-bit, Python 3.11+
- Rust toolchain (launcher rebuild)
- Node.js (for React/Vite, optional)
