JSON-Driven Architecture Refactor

Overview

Created a comprehensive JSON-driven architecture that loads UI from declarative configurations, breaking down large components and creating an extensive hook library.

New Hook Library

Data Management Hooks (`/src/hooks/data/`)

useDataSource: Unified data source management (KV, static, computed)
useCRUD: Full CRUD operations for any data type
useSearchFilter: Search and filter functionality
useSort: Sorting with direction toggle
usePagination: Complete pagination logic
useSelection: Multi/single selection management

Form Hooks (`/src/hooks/forms/`)

useFormField: Field-level validation and state
useForm: Form submission with async support

New Atomic Components (`/src/components/atoms/`)

All components < 50 LOC:

DataList: Renders lists with empty states
StatCard: Metric display with trends and icons
ActionButton: Button with tooltip support
LoadingState: Configurable loading spinners
EmptyState: Empty state with optional actions

JSON Page Configuration

Created /src/config/pages/dashboard.json demonstrating:

Declarative card layouts
Data binding expressions
Computed data sources
Dynamic component rendering
Responsive grid configurations

JSON Page Renderer

/src/components/JSONPageRenderer.tsx interprets JSON schemas to render:

Multi-section layouts
Dynamic data bindings
Icon resolution from Phosphor
Gradient cards with sub-components
Stat cards from configuration

Architecture Benefits

No Code Changes: Update UI through JSON edits
Type-Safe: Full TypeScript support throughout
Composable: Mix JSON-driven and coded components
Maintainable: All components under 150 LOC
Testable: Hooks isolated from UI logic

Usage Example

import { JSONPageRenderer } from '@/components/JSONPageRenderer'
import dashboardSchema from '@/config/pages/dashboard.json'

function MyPage({ projectData }) {
  return (
    <JSONPageRenderer
      schema={dashboardSchema}
      data={projectData}
      functions={{ calculateCompletionScore }}
    />
  )
}

Next Steps

Expand JSON schemas for all pages
Add more computed data sources
Create schema validation
Build visual JSON editor
Add action bindings (click handlers, etc.)
