The Thread-Safe, State-Aware Interface that Weaves Itself.

LoomUI: The Thread-Safe Interface That Weaves Itself

LoomUI is a next-generation Python framework designed to bridge the gap between simple scripts and complex dashboards. Unlike other libraries that require callbacks, manual state management, or reactive graph definitions, LoomUI uses Invisible State Monitoring to update your UI automatically.

Write standard Python. Get a real-time SPA (Single Page Application).

🚀 Key Features

• 🪄 Function-is-the-Interface: Use the @expose decorator to instantly turn any Python function into a web form with inputs and validation.
• 🧠 Invisible State: No session_state["key"]. No callbacks. Just modify state.x = 5, and the UI updates.
• ⚡ WebSocket Powered: Built on FastAPI and Uvicorn for bi-directional, real-time communication.
• 🎨 Theme Engine: One-line CSS variable theming. Cyberpunk? Dark mode? Corporate? Just pass a dict.
• 📊 Integrated Charts: Full Chart.js support right out of the box.

📦 Installation

pip install loomui

⚡ Quick Start: The "Magic" Mode

The fastest way to build a tool. LoomUI inspects your function signatures and generates the UI.

from loom import LoomApp, expose

app = LoomApp()

@expose
def calculate_roi(investment: float, rate: float, years: int):
    """Calculates return on investment instantly."""
    return investment * ((1 + rate) ** years)

if __name__ == "__main__":
    app.run()

---

🛠️ Advanced: The "Layout" Mode

For full control over dashboards, charts, and state.

from loom import LoomApp, state

# 1. Define Theme
dark_theme = {"background": "#111", "text": "#0f0", "primary": "#d0f"}
app = LoomApp(theme=dark_theme)

# 2. Define State
state.count = 0

# 3. Define Logic
def increment():
    state.count += 1

# 4. Build Layout
with app.root:
    app.Text("# System Monitor")
    
    with app.Row():
        app.Button("INCREASE LOAD", on_click=increment)
        app.Text("Current Load: $count") # '$' binds automatically to state
    
    app.Chart(
        type="line",
        labels=["00:00", "00:01", "00:02"],
        data=[10, 25, 60]
    )

if __name__ == "__main__":
    app.run()

🎨 Theming

LoomUI supports full customization via a simple dictionary:

theme = {
    "background": "#ffffff",
    "surface": "#f4f4f9", 
    "text": "#333333",
    "primary": "#6200ea",
    "radius": "12px"
}
app = LoomApp(theme=theme)
