# DashA2UI

A2UI Protocol Implementation for Dash - Declarative UI generation for LLM agents.

## Overview

DashA2UI implements the [A2UI (Agent-to-User Interface) Protocol v0.8](https://github.com/google/A2UI) for generating declarative, streaming UI payloads that can be rendered by A2UI-compatible clients.

A2UI is designed to be:
- **LLM-friendly**: Flat adjacency list model, easy for LLMs to generate incrementally
- **Secure**: Declarative data format, not executable code
- **Framework-agnostic**: Same payload renders on web, Flutter, etc.

## Installation

### From GitHub (recommended until published to PyPI)

```bash
# Core package (no framework dependencies)
pip install "dasha2ui @ git+https://github.com/Cemberk/dasha2ui.git"

# With Dash renderer support
pip install "dasha2ui[dash] @ git+https://github.com/Cemberk/dasha2ui.git"

# Everything
pip install "dasha2ui[all] @ git+https://github.com/Cemberk/dasha2ui.git"
```

### From Local Clone

```bash
git clone https://github.com/Cemberk/dasha2ui.git
cd dasha2ui
pip install -e .[dash]  # Editable install with Dash support
```

### From PyPI (when published)

```bash
pip install dasha2ui[dash]
pip install dasha2ui[all]
```

## Quick Start

### Building A2UI Surfaces

```python
from dasha2ui import (
    A2UISurface, text, row, column, card,
    TextUsageHint, Distribution
)

# Create a surface
surface = A2UISurface("my-dashboard")

# Add components
title = surface.add(text("Dashboard", usage_hint=TextUsageHint.H1))
subtitle = surface.add(text("Welcome!", usage_hint=TextUsageHint.BODY))

# Create layout
content = surface.add(column([title.id, subtitle.id]))

# Build A2UI messages
messages = surface.build(root_id=content.id)

# Output as JSON
print(surface.to_json_array(root_id=content.id))
```

### Using Pre-built Templates

```python
from dasha2ui import build_dashboard_ui

messages = build_dashboard_ui(
    title="Sales Dashboard",
    metrics=[
        {"title": "Total Sales", "value_path": "/sales/total", "icon": "shoppingCart"},
        {"title": "Orders", "value_path": "/sales/orders", "icon": "payment"},
    ],
    data={"sales": {"total": "$12,345", "orders": "156"}}
)
```

### Rendering in Dash

```python
from dasha2ui.renderers.dash_renderer import A2UIRenderer

# Process A2UI messages
renderer = A2UIRenderer()
renderer.process_messages(messages)

# Get Dash component
dash_component = renderer.render()

# Use in your Dash app
app.layout = html.Div([dash_component])
```

## Components

DashA2UI supports all A2UI v0.8 standard components:

### Layout
- `row()` - Horizontal flex layout
- `column()` - Vertical flex layout
- `list_component()` - Scrollable list
- `card()` - Card container

### Content
- `text()` - Text with typography hints (h1-h5, body, caption)
- `image()` - Image with sizing hints
- `icon()` - Material Design icons
- `divider()` - Horizontal/vertical divider

### Interactive
- `button()` - Button with action
- `text_field()` - Text input
- `checkbox()` - Checkbox
- `slider()` - Slider
- `multiple_choice()` - Selection
- `tabs()` - Tab navigation
- `modal()` - Modal dialog

### Media
- `video()` - Video player
- `audio_player()` - Audio player

## Data Binding

Components can bind to a data model using paths:

```python
from dasha2ui import text, BoundString, A2UISurface

surface = A2UISurface("example")

# Bind text to data model path
value = surface.add(text(BoundString.bound("/metrics/total")))

# Set data
surface.set_data({"metrics": {"total": "1,234"}})
```

## Streaming

For progressive UI generation:

```python
from dasha2ui import A2UIStream, text, column

stream = A2UIStream("dashboard")

# Send initial structure
yield stream.begin_rendering("root")

# Stream components
title = text("Loading...", id="title")
yield stream.surface_update([title])

# Update data progressively
yield stream.data_update({"status": "Ready"})
```

## LLM Integration

A2UI is designed for LLM output. Example prompt:

```
Generate A2UI JSON to display a dashboard with:
- Title: "Performance Metrics"
- 3 metric cards showing CPU, Memory, Disk usage

Output format: JSON array of A2UI messages
```
