# JSON-Driven Pages Conversion
|
|
|
|
## Overview
|
|
Converted three complex pages (Models, Component Trees, and Workflows) from traditional React component implementations to JSON-driven configuration. This demonstrates the power and flexibility of the JSON-driven UI system.
|
|
|
|
## Converted Pages
|
|
|
|
### 1. Models Designer (JSON)
|
|
**File**: `/src/config/pages/model-designer.json`
|
|
**Component**: `JSONModelDesigner.tsx`
|
|
|
|
**Features**:
|
|
- KV-persisted model data (`app-models`)
|
|
- Computed values for selected model and model count
|
|
- Sidebar with model list and create button
|
|
- Empty state with call-to-action
|
|
- Main editor area with conditional rendering
|
|
- Fully reactive state management
|
|
|
|
**Data Sources**:
|
|
- `models` (KV) - Persistent model storage
|
|
- `selectedModelId` (static) - Currently selected model
|
|
- `selectedModel` (computed) - Derived from models + selectedModelId
|
|
- `modelCount` (computed) - Total number of models
|
|
|
|
### 2. Component Trees Manager (JSON)
|
|
**File**: `/src/config/pages/component-tree.json`
|
|
**Component**: `JSONComponentTreeManager.tsx`
|
|
|
|
**Features**:
|
|
- KV-persisted component tree data (`app-component-trees`)
|
|
- Tree selection and navigation
|
|
- Hierarchical component structure display
|
|
- Create/edit/delete operations
|
|
- Badge showing tree count
|
|
- Empty state with guided onboarding
|
|
|
|
**Data Sources**:
|
|
- `trees` (KV) - Persistent tree storage
|
|
- `selectedTreeId` (static) - Current tree selection
|
|
- `selectedTree` (computed) - Derived tree data
|
|
- `treeCount` (computed) - Total tree count
|
|
|
|
### 3. Workflows Designer (JSON)
|
|
**File**: `/src/config/pages/workflow-designer.json`
|
|
**Component**: `JSONWorkflowDesigner.tsx`
|
|
|
|
**Features**:
|
|
- KV-persisted workflow data (`app-workflows`)
|
|
- Status filtering (all, success, failed, running)
|
|
- Node and connection management
|
|
- Visual workflow canvas
|
|
- Status-based badges and counts
|
|
- Multi-state workflow support
|
|
|
|
**Data Sources**:
|
|
- `workflows` (KV) - Persistent workflow storage
|
|
- `selectedWorkflowId` (static) - Current workflow
|
|
- `statusFilter` (static) - Filter state
|
|
- `selectedWorkflow` (computed) - Current workflow data
|
|
- `filteredWorkflows` (computed) - Filtered by status
|
|
- `statusCounts` (computed) - Counts per status
|
|
|
|
## Architecture Benefits
|
|
|
|
### Declarative Configuration
|
|
- UI structure defined in JSON, not JSX
|
|
- Easy to understand page structure at a glance
|
|
- Non-developers can read and potentially modify schemas
|
|
|
|
### Reactive Data Flow
|
|
- Computed values automatically update when dependencies change
|
|
- KV storage ensures data persistence between sessions
|
|
- No manual useState/useEffect boilerplate needed
|
|
|
|
### Consistent Patterns
|
|
- All three pages follow the same structural pattern:
|
|
- Sidebar with list and actions
|
|
- Main content area with conditional rendering
|
|
- Empty states with CTAs
|
|
- KV-backed data persistence
|
|
- Computed derived values
|
|
|
|
### Maintainability
|
|
- Centralized component definitions
|
|
- Separation of data, structure, and behavior
|
|
- Easy to add new pages following the same pattern
|
|
- Version control friendly (JSON diffs are clear)
|
|
|
|
## Implementation Details
|
|
|
|
### Page Structure Pattern
|
|
```json
|
|
{
|
|
"dataSources": [
|
|
{ "type": "kv", "key": "...", "defaultValue": [...] },
|
|
{ "type": "static", "defaultValue": null },
|
|
{ "type": "computed", "compute": "...", "dependencies": [...] }
|
|
],
|
|
"components": [
|
|
{
|
|
"type": "div",
|
|
"props": { "className": "..." },
|
|
"children": [
|
|
{
|
|
"type": "Component",
|
|
"bindings": { "prop": { "source": "...", "path": "..." } },
|
|
"events": [
|
|
{ "event": "click", "actions": [...] }
|
|
]
|
|
}
|
|
]
|
|
}
|
|
]
|
|
}
|
|
```
|
|
|
|
### Component Registry Integration
|
|
All JSON page wrappers are registered in `component-registry.ts`:
|
|
- `JSONModelDesigner`
|
|
- `JSONComponentTreeManager`
|
|
- `JSONWorkflowDesigner`
|
|
|
|
### Page Configuration
|
|
Added to `pages.json` with feature toggle support:
|
|
- `models-json` (toggle: `modelsJSON`)
|
|
- `component-trees-json` (toggle: `componentTreesJSON`)
|
|
- `workflows-json` (toggle: `workflowsJSON`)
|
|
|
|
### Seed Data
|
|
Created realistic seed data for all three pages:
|
|
- **Models**: User, Post, Comment models with fields
|
|
- **Component Trees**: Dashboard and Profile layouts
|
|
- **Workflows**: Registration, Data Processing, Payment flows
|
|
|
|
## Usage
|
|
|
|
### Enabling JSON Pages
|
|
Toggle the JSON versions on/off via the Features page:
|
|
- Enable "Models (JSON)" toggle
|
|
- Enable "Component Trees (JSON)" toggle
|
|
- Enable "Workflows (JSON)" toggle
|
|
|
|
### Comparing Implementations
|
|
Both traditional and JSON versions are available:
|
|
- Traditional: `models`, `component-trees`, `workflows`
|
|
- JSON: `models-json`, `component-trees-json`, `workflows-json`
|
|
|
|
This allows side-by-side comparison of approaches.
