# JSON UI System Implementation Summary
## Overview
Successfully implemented a comprehensive JSON-driven UI system that allows building complex React interfaces from declarative JSON configurations, significantly reducing the need for manual React component coding.
## What Was Built
### Core Infrastructure
#### 1. JSON UI Library (`/src/lib/json-ui/`)
- **schema.ts**: Zod schemas for type-safe JSON configurations
- UIComponent, Form, Table, Dialog, Layout, Tabs, Menu schemas
- Data binding, event handling, and conditional rendering support
- Type exports for TypeScript integration
- **component-registry.ts**: Central registry of available components
- All shadcn/ui components (Button, Card, Input, Table, etc.)
- HTML primitives (div, span, h1-h6, section, etc.)
- Phosphor icon components (40+ icons)
- Extensible registration system
- **renderer.tsx**: Dynamic React component renderer
- Interprets JSON and renders React components
- Handles data binding with automatic updates
- Event handler execution
- Conditional rendering based on data
- Array looping for lists
- Form rendering with validation
- **hooks.ts**: React hooks for data management
- `useJSONDataSource`: Single data source management (KV, API, static, computed)
- `useJSONDataSources`: Multiple data sources orchestration
- `useJSONActions`: Action registration and execution
- **utils.ts**: Helper functions
- Data binding resolution
- Nested object value access
- Condition evaluation
- Data transformation
- Class name merging
#### 2. Components
- **JSONUIPage.tsx**: Renders a complete page from JSON config
- Data source initialization
- Action handling
- Layout rendering
- **JSONUIShowcase.tsx**: Demo page showing all examples
- Tabbed interface for different examples
- Toggle between JSON view and rendered preview
- Live demonstrations of capabilities
#### 3. JSON Configuration Examples (`/src/config/ui-examples/`)
- **dashboard.json**: Complete dashboard
- Stats cards with data binding
- Activity feed with list looping
- Quick action buttons
- Multi-section layout
- **form.json**: User registration form
- Text, email, password inputs
- Textarea for bio

- Data binding for all fields
- **table.json**: Interactive data table
- Dynamic rows from array data
- Status badges
- Per-row action buttons (view, edit, delete)
- Event handlers with parameters
- **settings.json**: Settings panel
- Tabbed interface (General, Notifications, Security)
- Switch toggles for preferences
- Select dropdown for language
- Multiple independent data sources
- Save/reset functionality
#### 4. Documentation
- **JSON-UI-SYSTEM.md**: Complete reference guide
- System overview and features
- JSON structure documentation
- Component type reference
- Data binding guide
- Event handling patterns
- Best practices
- Extension guide
- **ui-examples/README.md**: Examples guide
- Description of each example
- Key features demonstrated
- Usage instructions
- Best practices for creating new UIs
#### 5. Integration
- Added JSONUIShowcase to pages.json configuration
- Registered component in orchestration registry
- Added new "JSON UI" tab to application navigation
## Key Features Implemented
### 1. Declarative UI Definition
- Define complete UIs in JSON without writing React code
- Compose components using nested JSON structures
- Configure props, styling, and behavior declaratively
### 2. Data Binding
- Bind component values to data sources
- Automatic synchronization between data and UI
- Support for nested data paths
- Multiple data source types (static, API, KV, computed)
### 3. Event Handling
- Define event handlers in JSON
- Pass parameters to action handlers
- Support for all common events (onClick, onChange, onSubmit, etc.)
- Custom action execution with context
### 4. Advanced Rendering
- **Conditional Rendering**: Show/hide elements based on conditions
- **List Looping**: Render arrays with automatic item binding
- **Dynamic Props**: Calculate props from data at render time
- **Nested Components**: Unlimited component composition depth
### 5. Component Library
- Full shadcn/ui component suite available
- HTML primitive elements
- Icon library (Phosphor icons)
- Easy to extend with custom components
### 6. Type Safety
- Zod schema validation for all JSON configs
- TypeScript types exported from schemas
- Runtime validation of configurations
## Benefits
### For Developers
✅ Rapid prototyping and iteration
✅ Less boilerplate code to write
✅ Consistent component usage
✅ Easy to test and validate UIs
✅ Clear separation of structure and logic
✅ Version control friendly (JSON diffs)
### For Non-Developers
✅ Build UIs without React knowledge
✅ Modify existing UIs easily
✅ Clear, readable configuration format
✅ Immediate visual feedback
### For the Project
✅ Reduced code duplication
✅ Standardized UI patterns
✅ Easier maintenance
✅ Dynamic UI loading capabilities
✅ Configuration-driven development
## Architecture Decisions
### Why JSON Instead of JSX?
- **Declarative**: More explicit about structure and intent
- **Serializable**: Can be stored, transmitted, and versioned
- **Accessible**: Non-developers can understand and modify
- **Dynamic**: Can be loaded and changed at runtime
- **Validated**: Type-checked with Zod schemas
### Component Registry Pattern
- Centralized component access
- Easy to extend with new components
- Type-safe component resolution
- Supports both React components and HTML elements
### Data Source Abstraction
- Multiple source types under one interface
- Easy to add new source types
- Separates data concerns from UI
- Enables data persistence strategies
## Example Usage
### Simple Button
```json
{
"id": "my-button",
"type": "Button",
"props": { "variant": "primary" },
"events": { "onClick": "handle-click" },
"children": "Click Me"
}
```
### Data-Bound Card
```json
{
"id": "user-card",
"type": "Card",
"children": [
{
"id": "user-name",
"type": "CardTitle",
"dataBinding": "user.name"
}
]
}
```
### List with Loop
```json
{
"id": "items-list",
"type": "div",
"loop": {
"source": "items",
"itemVar": "item"
},
"children": [
{
"id": "item-name",
"type": "p",
"dataBinding": "item.name"
}
]
}
```

# JSON UI System Documentation
## Overview
The JSON UI System is a declarative framework for building React user interfaces from JSON configurations. Instead of writing React components, you define your UI structure, data sources, and event handlers in JSON files, which are then rendered dynamically.
## Key Features
- **Fully Declarative**: Define complete UIs without writing React code
- **Data Binding**: Automatic synchronization between data sources and UI components
- **Event Handling**: Configure user interactions and actions in JSON
- **Component Library**: Access to all shadcn/ui components and Phosphor icons
- **Conditional Rendering**: Show/hide elements based on data conditions
- **Looping**: Render lists from array data sources
- **Type-Safe**: Validated with Zod schemas
## JSON Structure
### Basic Page Configuration
```json
{
"id": "my-page",
"title": "My Page",
"description": "Page description",
"layout": {
"type": "flex",
"direction": "column",
"gap": "6",
"padding": "6",
"className": "h-full bg-background",
"children": []
},
"dataSources": {},
"actions": []
}
```
### Components
Components are the building blocks of your UI. Each component has:
```json
{
"id": "unique-id",
"type": "ComponentName",
"props": {},
"className": "tailwind-classes",
"style": {},
"children": [],
"dataBinding": "dataSource.path",
"events": {},
"conditional": {},
"loop": {}
}
```
#### Component Types
**HTML Primitives**:
- `div`, `span`, `p`, `h1`, `h2`, `h3`, `h4`, `h5`, `h6`
- `section`, `article`, `header`, `footer`, `main`, `aside`, `nav`
**shadcn/ui Components**:
- `Button`, `Input`, `Textarea`, `Label`
- `Card`, `CardHeader`, `CardTitle`, `CardDescription`, `CardContent`, `CardFooter`
- `Badge`, `Separator`, `Alert`, `AlertDescription`, `AlertTitle`
- `Switch`, `Checkbox`, `RadioGroup`, `RadioGroupItem`
- `Select`, `SelectContent`, `SelectItem`, `SelectTrigger`, `SelectValue`
- `Table`, `TableBody`, `TableCell`, `TableHead`, `TableHeader`, `TableRow`
- `Tabs`, `TabsContent`, `TabsList`, `TabsTrigger`
- `Dialog`, `DialogContent`, `DialogDescription`, `DialogFooter`, `DialogHeader`, `DialogTitle`
- `Skeleton`, `Progress`, `Avatar`, `AvatarFallback`, `AvatarImage`
**Icons** (Phosphor):
- `ArrowLeft`, `ArrowRight`, `Check`, `X`, `Plus`, `Minus`
- `Search`, `Filter`, `Download`, `Upload`, `Edit`, `Trash`
- `Eye`, `EyeOff`, `ChevronUp`, `ChevronDown`, `ChevronLeft`, `ChevronRight`
- `Settings`, `User`, `Bell`, `Mail`, `Calendar`, `Clock`, `Star`
- `Heart`, `Share`, `Link`, `Copy`, `Save`, `RefreshCw`
- `AlertCircle`, `Info`, `HelpCircle`, `Home`, `Menu`
- And many more...
### Data Binding
Bind component values to data sources:
```json
{
"id": "stat-value",
"type": "p",
"className": "text-3xl font-bold",
"dataBinding": "stats.users"
}
```
For nested data:
```json
{
"dataBinding": {
"source": "user",
"path": "profile.name"
}
}
```
### Event Handlers
Configure user interactions:
```json
{
"events": {
"onClick": "action-id"
}
}
```
With parameters:
```json
{
"events": {
"onClick": {
"action": "delete-item",
"params": {
"itemId": "item.id"
}
}
}
}
```
Common events:
- `onClick`, `onDoubleClick`
- `onChange`, `onInput`, `onBlur`, `onFocus`
- `onSubmit`
- `onCheckedChange` (for checkboxes/switches)
### Data Sources
Define where your data comes from:
```json
{
"dataSources": {
"stats": {
"type": "static",
"config": {
"users": 1234,
"projects": 45
}
},
"users": {
"type": "api",
"config": {
"url": "/api/users",
"method": "GET"
}
},
"preferences": {
"type": "kv",
"config": {
"key": "user-preferences",
"defaultValue": {}
}
}
}
}
```
Data source types:
- `static`: Hardcoded data in the JSON
- `api`: Fetch from an API endpoint
- `kv`: Persist to Spark KV store
- `computed`: Calculate from other data sources
### Conditional Rendering
Show components based on conditions:
```json
{
"conditional": {
"if": "user.isAdmin",
"then": {
"id": "admin-panel",
"type": "div",
"children": "Admin controls"
},
"else": {
"id": "guest-message",
"type": "p",
"children": "Please log in"
}
}
}
```
### Looping
Render arrays of data:
```json
{
"loop": {
"source": "projects",
"itemVar": "project",
"indexVar": "index"
},
"children": [
{
"id": "project-card",
"type": "Card",
"children": [
{
"id": "project-name",
"type": "CardTitle",
"dataBinding": "project.name"
}
]
}
]
}
```
## Examples
### Dashboard Example
See `/src/config/ui-examples/dashboard.json` for a complete dashboard with:
- Stats cards
- Activity feed with looping
- Quick action buttons
- Static data sources
### Form Example
See `/src/config/ui-examples/form.json` for a registration form with:
- Text inputs
- Email and password fields
- Textarea
- Checkbox
- Form submission handling
- Data binding for all fields
### Table Example
See `/src/config/ui-examples/table.json` for a data table with:
- Row looping
- Status badges
- Action buttons per row
- Hover states
## Best Practices
1. **Unique IDs**: Always provide unique `id` values for every component
2. **Semantic Components**: Use HTML primitives (`div`, `section`, etc.) for layout, shadcn components for interactive elements
3. **Data Binding**: Bind to data sources rather than hardcoding values
4. **Event Naming**: Use clear, action-oriented event names (`create-user`, `delete-project`)
5. **Responsive Design**: Use Tailwind responsive prefixes (`md:`, `lg:`) in `className`
6. **Component Hierarchy**: Keep component trees shallow for better performance
## Extending the System
### Register Custom Components
```typescript
import { registerComponent } from '@/lib/json-ui/component-registry'
import { MyCustomComponent } from './MyCustomComponent'
registerComponent('MyCustom', MyCustomComponent)
```
### Add Custom Data Source Types
Edit `/src/lib/json-ui/hooks.ts` to add new data source handlers.
### Add Custom Actions
Actions are handled in the parent component. Add new action handlers in your page component:
```typescript
const handleAction = (handler: EventHandler, event?: any) => {
switch (handler.action) {
case 'my-custom-action':
// Handle your custom action
break
}
}
```
## File Locations
- **Schema Definitions**: `/src/lib/json-ui/schema.ts`
- **Component Registry**: `/src/lib/json-ui/component-registry.ts`
- **Renderer**: `/src/lib/json-ui/renderer.tsx`
- **Hooks**: `/src/lib/json-ui/hooks.ts`
- **Utils**: `/src/lib/json-ui/utils.ts`
- **Examples**: `/src/config/ui-examples/`
- **Demo Page**: `/src/components/JSONUIShowcase.tsx`
## Advantages
**No React Knowledge Required**: Build UIs with JSON
**Rapid Prototyping**: Create and iterate on UIs quickly
**Consistent Styling**: Automatic adherence to design system
**Easy Testing**: JSON configurations are easy to validate
**Version Control Friendly**: Clear diffs when UI changes
**Dynamic Loading**: Load UI configurations at runtime
**Type Safety**: Zod schemas validate configurations
## Limitations
⚠️ **Complex Logic**: Advanced state management still requires React components
⚠️ **Performance**: Very large component trees may be slower than hand-coded React
⚠️ **Debugging**: Stack traces point to the renderer, not your JSON
⚠️ **Learning Curve**: Understanding the JSON schema takes time
## Future Enhancements
- [ ] Visual JSON UI builder/editor
- [ ] More complex data transformations
- [ ] Animation configurations
- [ ] Form validation schemas in JSON
- [ ] GraphQL data source support
- [ ] WebSocket data sources for real-time updates
- [ ] Export JSON UI to React code
- [ ] JSON UI template library

# Migrating React Components to JSON UI
This guide helps you convert existing React components to JSON UI configurations.
## When to Migrate
**Good Candidates:**
- Static layouts and dashboards
- Forms with standard inputs
- Data tables and lists
- Settings panels
- Card-based UIs
- Simple interactive components
**Poor Candidates:**
- Complex state management
- Heavy animations and transitions
- Canvas/WebGL rendering
- Real-time collaboration features
- Components with custom hooks
- Performance-critical rendering
## Migration Process
### Step 1: Identify Component Structure
**React Component:**
```tsx
export function UserCard({ user }) {
return (
<Card>
<CardHeader>
<CardTitle>{user.name}</CardTitle>
<CardDescription>{user.email}</CardDescription>
</CardHeader>
<CardContent>
<p>{user.bio}</p>
</CardContent>
</Card>
)
}
```
**Break Down:**
1. Root component: Card
2. Children: CardHeader, CardContent
3. Data: user object with name, email, bio
4. No events or complex logic
### Step 2: Create Data Sources
Identify where data comes from:
```json
{
"dataSources": {
"user": {
"type": "static",
"config": {
"name": "John Doe",
"email": "john@example.com",
"bio": "Software developer"
}
}
}
}
```
### Step 3: Build Component Tree
Convert JSX to JSON:
```json
{
"id": "user-card",
"type": "Card",
"children": [
{
"id": "card-header",
"type": "CardHeader",
"children": [
{
"id": "user-name",
"type": "CardTitle",
"dataBinding": "user.name"
},
{
"id": "user-email",
"type": "CardDescription",
"dataBinding": "user.email"
}
]
},
{
"id": "card-content",
"type": "CardContent",
"children": [
{
"id": "user-bio",
"type": "p",
"dataBinding": "user.bio"
}
]
}
]
}
```
### Step 4: Convert Event Handlers
**React:**
```tsx
<Button onClick={() => handleDelete(user.id)}>
Delete
</Button>
```
**JSON:**
```json
{
"type": "Button",
"events": {
"onClick": {
"action": "delete-user",
"params": {
"userId": "user.id"
}
}
},
"children": "Delete"
}
```
Then implement the action handler in your page component.
### Step 5: Handle Lists
**React:**
```tsx
{users.map(user => (
<UserCard key={user.id} user={user} />
))}
```
**JSON:**
```json
{
"loop": {
"source": "users",
"itemVar": "user",
"indexVar": "index"
},
"children": [
{
"id": "user-card",
"type": "Card",
"children": [...]
}
]
}
```
### Step 6: Convert Conditionals
**React:**
```tsx
{user.isAdmin ? (
<AdminPanel />
) : (
<UserPanel />
)}
```
**JSON:**
```json
{
"conditional": {
"if": "user.isAdmin",
"then": {
"id": "admin-panel",
"type": "AdminPanel"
},
"else": {
"id": "user-panel",
"type": "UserPanel"
}
}
}
```
## Common Patterns
### Form with State
**React:**
```tsx
const [formData, setFormData] = useState({})
const handleChange = (e) => {
setFormData(prev => ({...prev, [e.target.name]: e.target.value}))
}
return (
<Input
name="email"
value={formData.email}
onChange={handleChange}
/>
)
```
**JSON:**
```json
{
"type": "Input",
"props": {
"name": "email"
},
"dataBinding": "formData.email",
"events": {
"onChange": "update-field"
}
}
```
Data source:
```json
{
"dataSources": {
"formData": {
"type": "static",
"config": {
"email": ""
}
}
}
}
```
### Styling and Classes
**React:**
```tsx
<div className={cn(
"flex items-center gap-4",
isActive && "bg-primary"
)}>
```
**JSON:**
```json
{
"type": "div",
"className": "flex items-center gap-4",
"conditional": {
"if": "isActive",
"then": {
"type": "div",
"className": "flex items-center gap-4 bg-primary"
}
}
}
```
Or better, use data binding for dynamic classes:
```json
{
"type": "div",
"className": "flex items-center gap-4",
"style": {
"backgroundColor": "isActive ? 'var(--primary)' : 'transparent'"
}
}
```
### API Data
**React:**
```tsx
const [users, setUsers] = useState([])
useEffect(() => {
fetch('/api/users')
.then(r => r.json())
.then(setUsers)
}, [])
```
**JSON:**
```json
{
"dataSources": {
"users": {
"type": "api",
"config": {
"url": "/api/users",
"method": "GET"
}
}
}
}
```
### Persistent Data
**React:**
```tsx
const [prefs, setPrefs] = useKV('user-prefs', {})
```
**JSON:**
```json
{
"dataSources": {
"prefs": {
"type": "kv",
"config": {
"key": "user-prefs",
"defaultValue": {}
}
}
}
}
```
## Complete Migration Example
### Before (React)
```tsx
export function ProjectList() {
const [projects, setProjects] = useState([])
const [loading, setLoading] = useState(true)
useEffect(() => {
fetchProjects().then(data => {
setProjects(data)
setLoading(false)
})
}, [])
const handleDelete = (id) => {
deleteProject(id).then(() => {
setProjects(prev => prev.filter(p => p.id !== id))
})
}
if (loading) return <Skeleton />
return (
<div className="space-y-4">
<h1>Projects</h1>
{projects.map(project => (
<Card key={project.id}>
<CardHeader>
<CardTitle>{project.name}</CardTitle>
<Badge>{project.status}</Badge>
</CardHeader>
<CardContent>
<p>{project.description}</p>
</CardContent>
<CardFooter>
<Button onClick={() => handleDelete(project.id)}>
Delete
</Button>
</CardFooter>
</Card>
))}
</div>
)
}
```
### After (JSON)
```json
{
"id": "project-list",
"layout": {
"type": "flex",
"direction": "column",
"gap": "4",
"className": "p-6",
"children": [
{

## Benefits After Migration
✅ No React state management boilerplate
✅ Configuration can be modified without code changes
✅ Easy to A/B test different layouts
✅ Non-developers can make UI changes
✅ Clear separation of data and presentation
✅ Version control shows structural changes clearly
## Challenges and Solutions
### Challenge: Complex State Logic
**Solution:** Keep state management in React, only migrate presentational parts
### Challenge: Custom Hooks
**Solution:** Expose hook data through data sources
### Challenge: Performance Issues
**Solution:** Use static components for hot paths, JSON for configurable areas
### Challenge: Type Safety
**Solution:** Use Zod schemas to validate JSON at runtime
## Testing Migrated Components
1. **Visual Comparison**: Compare side-by-side with original
2. **Interaction Testing**: Verify all events work correctly
3. **Data Flow**: Confirm data binding updates properly
4. **Edge Cases**: Test with empty data, errors, loading states
5. **Performance**: Check render performance hasn't regressed
## Incremental Migration Strategy
1. Start with static content pages
2. Move to simple forms
3. Migrate data tables and lists
4. Convert settings and configuration UIs
5. Leave complex interactive components in React
## When to Stop
If you encounter:
- More than 3 levels of conditionals
- Complex derived state calculations
- Performance bottlenecks
- Heavy animation requirements
- Real-time data synchronization
Consider keeping it as a React component or creating a custom component for the JSON UI system.

# JSON UI Examples
This directory contains example JSON configurations that demonstrate the capabilities of the JSON UI system.
## Available Examples
### 1. Dashboard (`dashboard.json`)
A complete dashboard interface featuring:
- **Stats Cards**: Display key metrics with data binding
- **Activity Feed**: Shows recent activities using list looping
- **Quick Actions**: Grid of action buttons with click handlers
- **Static Data Sources**: Demonstrates hardcoded data in JSON
**Key Features Demonstrated:**
- Component composition with Cards
- Data binding to show dynamic values
- Event handlers for user interactions
- Grid layouts with responsive classes
- Icon components integration
### 2. Form (`form.json`)
A user registration form showcasing:
- **Text Inputs**: Name, email, password fields
- **Textarea**: Multi-line bio input
- **Checkbox**: Newsletter subscription
- **Form Actions**: Submit and cancel buttons
- **Data Binding**: Two-way binding for all form fields
**Key Features Demonstrated:**
- Form field components
- Input validation attributes
- onChange event handling
- Form data management
- Label-input associations
### 3. Data Table (`table.json`)
An interactive projects table with:
- **Table Structure**: Header and body rows
- **List Looping**: Dynamic rows from array data
- **Status Badges**: Visual status indicators
- **Row Actions**: View, edit, and delete buttons per row
- **Action Parameters**: Pass row data to event handlers
**Key Features Demonstrated:**
- Table components (TableHeader, TableBody, TableRow, TableCell)
- Loop rendering with itemVar and indexVar
- Badge components for status
- Icon buttons for actions
- Event handlers with dynamic parameters
### 4. Settings (`settings.json`)
A comprehensive settings panel featuring:
- **Tabbed Interface**: General, Notifications, Security tabs
- **Switch Toggles**: Enable/disable features
- **Select Dropdown**: Language selection
- **Multiple Data Sources**: Separate sources for each tab
- **Settings Persistence**: Save and reset functionality
**Key Features Demonstrated:**
- Tabs component with multiple TabsContent
- Switch components with data binding
- Select components with options
- Separator components for visual organization
- Multiple independent data sources
## How to Use These Examples
1. **View in the UI**: Navigate to the "JSON UI" page in the application to see live previews
2. **Toggle JSON View**: Click the "Show JSON" button to see the configuration
3. **Copy and Modify**: Use these as templates for your own UI configurations
4. **Learn by Example**: Each example builds on concepts from the previous ones
## Creating Your Own
To create a new JSON UI:
1. Create a new `.json` file in this directory
2. Follow the structure from existing examples
3. Import it in `JSONUIShowcase.tsx`:
```typescript
import myExample from '@/config/ui-examples/my-example.json'
```
4. Add it to the examples object:
```typescript
myExample: {
name: 'My Example',
description: 'Description here',
icon: IconComponent,
config: myExample,
}
```
## JSON Structure Reference
Each JSON file should have:
- `id`: Unique identifier
- `title`: Display title
- `description`: Brief description
- `layout`: Root layout configuration
- `type`: Layout type (flex, grid, etc.)
- `children`: Array of child components
- `dataSources`: Data sources configuration
- `actions` (optional): Action definitions
## Best Practices
1. **Start Simple**: Begin with basic layouts before adding complexity
2. **Use Semantic IDs**: Give components meaningful, descriptive IDs
3. **Test Data First**: Start with static data sources before moving to API/KV
4. **Incremental Development**: Add features one at a time
5. **Refer to Documentation**: See `/docs/JSON-UI-SYSTEM.md` for complete reference
## Tips
- Use the existing examples as starting points
- Keep component trees shallow for better performance
- Leverage Tailwind classes for styling
- Use data binding instead of hardcoded values
- Group related settings in separate data sources

# JSON UI System
A comprehensive declarative UI framework for building React interfaces from JSON configurations.
## 📁 Directory Structure
```
src/lib/json-ui/
├── index.ts # Main exports
├── schema.ts # Zod schemas for type validation
├── component-registry.ts # Component registry and lookup
├── renderer.tsx # React renderer for JSON configs
├── hooks.ts # React hooks for data management
├── utils.ts # Utility functions
└── validator.ts # Configuration validation
```
## 🚀 Quick Start
### 1. Create a JSON Configuration
```json
{
"id": "my-page",
"title": "My Page",
"layout": {
"type": "flex",
"direction": "column",
"children": [
{
"id": "greeting",
"type": "h1",
"children": "Hello World"
},
{
"id": "cta-button",
"type": "Button",
"events": {"onClick": "greet"},
"children": "Click Me"
}
]
},
"dataSources": {}
}
```
### 2. Render the Configuration
```tsx
import { JSONUIPage } from '@/components/JSONUIPage'
import config from './my-config.json'
export function MyPage() {
return <JSONUIPage jsonConfig={config} />
}
```
## 📚 Documentation
- **[Complete Guide](/docs/JSON-UI-SYSTEM.md)** - Full system documentation
- **[Quick Reference](/docs/JSON-UI-QUICK-REF.md)** - Component and syntax quick reference
- **[Migration Guide](/docs/MIGRATING-TO-JSON-UI.md)** - Convert React to JSON UI
- **[Examples README](/src/config/ui-examples/README.md)** - Example configurations
## 🎯 Core Concepts
### Components
Define UI elements using JSON:
```json
{
"id": "my-button",
"type": "Button",
"props": {"variant": "primary"},
"className": "mt-4",
"children": "Submit"
}
```
### Data Binding
Connect UI to data sources:
```json
{
"type": "p",
"dataBinding": "user.name"
}
```
### Event Handling
Respond to user interactions:
```json
{
"events": {
"onClick": "save-data"
}
}
```
### Looping
Render lists from arrays:
```json
{
"loop": {
"source": "items",
"itemVar": "item"
},
"children": [...]
}
```
### Conditionals
Show/hide based on conditions:
```json
{
"conditional": {
"if": "user.isAdmin",
"then": {...},
"else": {...}
}
}
```
## 🧩 Available Components
### Layout
- HTML primitives: `div`, `span`, `section`, `header`, etc.
### UI Components (shadcn/ui)
- `Button`, `Input`, `Textarea`, `Label`
- `Card`, `CardHeader`, `CardTitle`, `CardContent`, etc.
- `Table`, `TableHeader`, `TableBody`, `TableRow`, `TableCell`
- `Tabs`, `TabsList`, `TabsTrigger`, `TabsContent`
- `Badge`, `Separator`, `Alert`, `Switch`, `Checkbox`
- And 30+ more...
### Icons (Phosphor)
- `Plus`, `Minus`, `Edit`, `Trash`, `Eye`, `Settings`
- `User`, `Bell`, `Calendar`, `Star`, `Heart`
- And 30+ more...
## 💾 Data Sources
### Static Data
```json
{
"dataSources": {
"config": {
"type": "static",
"config": {"theme": "dark"}
}
}
}
```
### API Data
```json
{
"dataSources": {
"users": {
"type": "api",
"config": {"url": "/api/users"}
}
}
}
```
### KV Store
```json
{
"dataSources": {
"preferences": {
"type": "kv",
"config": {
"key": "user-prefs",
"defaultValue": {}
}
}
}
}
```
## 🛠️ Advanced Usage
### Custom Components
Register your own components:
```typescript
import { registerComponent } from '@/lib/json-ui'
import { MyCustomComponent } from './MyCustomComponent'
registerComponent('MyCustom', MyCustomComponent)
```
### Validation
Validate JSON configurations:
```typescript
import { validateJSONUI, prettyPrintValidation } from '@/lib/json-ui'
const result = validateJSONUI(myConfig)
console.log(prettyPrintValidation(result))
```
### Type Safety
Use TypeScript types from schemas:
```typescript
import type { UIComponent, PageUI } from '@/lib/json-ui'
const component: UIComponent = {
id: 'my-component',
type: 'Button',
children: 'Click Me'
}
```
## 📦 Exports
```typescript
// Schemas and Types
export type {
UIComponent,
Form,
Table,
Dialog,
Layout,
Tabs,
Menu,
PageUI,
DataBinding,
EventHandler
} from './schema'
// Components
export {
JSONUIRenderer,
JSONFormRenderer
} from './renderer'
export {
uiComponentRegistry,
registerComponent,
getUIComponent,
hasComponent
} from './component-registry'
// Hooks
export {
useJSONDataSource,
useJSONDataSources,
useJSONActions
} from './hooks'
// Utils
export {
resolveDataBinding,
getNestedValue,
setNestedValue,
evaluateCondition,
transformData
} from './utils'
// Validation
export {
validateJSONUI,
prettyPrintValidation
} from './validator'
```
## 🎨 Examples
See `/src/config/ui-examples/` for complete working examples:
- **dashboard.json** - Dashboard with stats and activity feed
- **form.json** - Registration form with validation
- **table.json** - Data table with row actions
- **settings.json** - Tabbed settings panel
View them live in the app under "JSON UI" tab.
## ✅ Benefits
- **Declarative**: Clear, readable configuration format
- **Type-Safe**: Validated with Zod schemas
- **Extensible**: Add custom components easily
- **Dynamic**: Load and modify UIs at runtime
- **Maintainable**: Separation of structure and logic
- **Accessible**: Non-developers can modify UIs
## ⚠️ Limitations
- Not suitable for complex state management
- Performance considerations for very large UIs
- Debugging can be more challenging
- Learning curve for the JSON schema
## 🔮 Future Enhancements
- Visual drag-and-drop UI builder
- GraphQL data source support
- Animation configurations
- Form validation schemas
- WebSocket real-time updates
- Export JSON to React code
- Template library with common patterns
