# JSON UI Enhancement - Implementation Summary
|
|
|
|
## Overview
|
|
Enhanced the JSON-driven UI system by creating additional custom hooks, atomic components, and comprehensive JSON page schemas to demonstrate loading more UI from JSON declarations while maintaining atomic component architecture.
|
|
|
|
## Custom Hooks Created
|
|
|
|
### 1. `useConfirmDialog` (/src/hooks/ui/use-confirm-dialog.ts)
|
|
- **Purpose**: Manages confirmation dialog state declaratively
|
|
- **Features**:
|
|
- Promise-based API for confirmation prompts
|
|
- Configurable title, description, and button text
|
|
- Support for default/destructive variants
|
|
- Clean state management with callbacks
|
|
|
|
### 2. `useFormState` (/src/hooks/ui/use-form-state.ts)
|
|
- **Purpose**: Handles form state, validation, and errors
|
|
- **Features**:
|
|
- Field-level validation with custom validators
|
|
- Touch state tracking for better UX
|
|
- Required field validation built-in
|
|
- Dirty state tracking
|
|
- Form reset functionality
|
|
- TypeScript-safe value management
|
|
|
|
### 3. `useListOperations` (/src/hooks/ui/use-list-operations.ts)
|
|
- **Purpose**: Provides comprehensive list manipulation operations
|
|
- **Features**:
|
|
- Add, update, remove, move items
|
|
- Multi-selection support
|
|
- Bulk operations (removeSelected)
|
|
- Find by ID helper
|
|
- Custom ID getter for flexibility
|
|
- Callback for external sync (e.g., persistence)
|
|
|
|
## Atomic Components Created
|
|
|
|
### 1. `ConfirmButton` (/src/components/atoms/ConfirmButton.tsx)
|
|
- Simple button with built-in confirmation prompt
|
|
- Async action support with loading states
|
|
- Customizable confirmation message
|
|
|
|
### 2. `MetricCard` (/src/components/atoms/MetricCard.tsx)
|
|
- Display key metrics with optional icons
|
|
- Trend indicators (up/down with percentage)
|
|
- Clean, card-based design
|
|
- Perfect for dashboards
|
|
|
|
### 3. `FilterInput` (/src/components/atoms/FilterInput.tsx)
|
|
- Search/filter input with magnifying glass icon
|
|
- Clear button appears when value exists
|
|
- Focus state animations
|
|
- Accessible and keyboard-friendly
|
|
|
|
### 4. `CountBadge` (/src/components/atoms/CountBadge.tsx)
|
|
- Display count with optional max value (e.g., "99+")
|
|
- Auto-hides when count is 0
|
|
- Multiple variants (default, secondary, destructive, outline)
|
|
|
|
## JSON Page Schema Created
|
|
|
|
### Analytics Dashboard Schema (/src/schemas/analytics-dashboard.json)
|
|
Comprehensive JSON-driven page demonstrating:
|
|
|
|
- **Data Sources**:
|
|
- KV-backed user list (persistent)
|
|
- Static filter query state
|
|
- Computed filtered users list
|
|
- Computed statistics (total, active, inactive)
|
|
|
|
- **UI Components**:
|
|
- Gradient header with title and subtitle
|
|
- Three metric cards showing total, active, and inactive users
|
|
- User directory card with:
|
|
- Badge showing filtered count
|
|
- Filter input for real-time search
|
|
- Dynamically rendered user cards
|
|
- Status badges with conditional variants
|
|
|
|
- **Data Bindings**:
|
|
- Reactive computed values
|
|
- Transform functions for complex UI updates
|
|
- Event handlers for user interactions
|
|
- Conditional rendering based on data
|
|
|
|
- **Seed Data**: 5 sample users with varied statuses
|
|
|
|
## Architecture Benefits
|
|
|
|
### Separation of Concerns
|
|
- **Hooks**: Business logic and state management
|
|
- **Atoms**: Simple, focused UI components
|
|
- **JSON Schemas**: Declarative UI definitions
|
|
- **Data Sources**: Centralized data management
|
|
|
|
### Reusability
|
|
- Hooks can be used across any component
|
|
- Atomic components are composable
|
|
- JSON schemas are templates for rapid development
|
|
|
|
### Maintainability
|
|
- Each component under 150 LOC (as per PRD guidelines)
|
|
- Clear single responsibility
|
|
- Type-safe with TypeScript
|
|
- Testable in isolation
|
|
|
|
### Scalability
|
|
- Add new hooks without touching components
|
|
- Create new atomic components independently
|
|
- Define entire pages in JSON without code changes
|
|
- Computed data sources prevent prop drilling
|
|
|
|
## Demo Use Cases
|
|
|
|
The created hooks and components enable:
|
|
|
|
1. **Form Management**: Use `useFormState` for complex forms with validation
|
|
2. **List Management**: Use `useListOperations` for CRUD operations on arrays
|
|
3. **Confirmations**: Use `useConfirmDialog` for destructive actions
|
|
4. **Dashboards**: Use `MetricCard` and JSON schemas for analytics UIs
|
|
5. **Search/Filter**: Use `FilterInput` and computed data sources for live filtering
|
|
6. **Counts**: Use `CountBadge` for notification counts or item totals
|
|
|
|
## Next Steps
|
|
|
|
The system is now ready for:
|
|
- Creating more JSON-driven pages for different use cases
|
|
- Building a visual schema editor for non-technical users
|
|
- Adding more specialized atomic components
|
|
- Creating additional reusable hooks for common patterns
