+# Config-Driven Architecture Guide
+
+## Overview
+
+This repository has been refactored to use a **config-driven architecture** where most of the React component structure, wiring, and actions are defined in `src/config/features.json` rather than in JSX/TSX files. This approach:
+
+- **Reduces boilerplate code** - Most UI wiring is done via configuration
+- **Improves maintainability** - Changes to UI structure can be made in JSON
+- **Enables rapid prototyping** - New features can be scaffolded from config
+- **Promotes reusability** - Atomic components and hooks are truly reusable
+- **Simplifies testing** - Playbooks defined in JSON for E2E tests
+
+## Architecture Components
+
+### 1. Component Tree Renderer (`src/utils/componentTreeRenderer.tsx`)
+
+The core of the config-driven architecture. It reads component tree definitions from `features.json` and dynamically renders React components.
+
+**Features:**
+- Template interpolation: `{{variable}}` syntax
+- Conditional rendering: `condition` property
+- Loops: `forEach` property for arrays
+- Action mapping: Maps string action names to functions
+- Icon rendering: Automatic Material-UI icon resolution
+
+**Example usage:**
+
+```tsx
+import { ComponentTreeRenderer } from '@/utils/componentTreeRenderer';
+import { getComponentTree } from '@/utils/featureConfig';
+
+const tree = getComponentTree('DashboardStatsCards');
+
+<ComponentTreeRenderer 
+  tree={tree}
+  context={{
+    data: { statsCards: [...] },
+    actions: { handleClick: () => {} },
+    state: { isOpen: false }
+  }}
+/>
+```
+
+### 2. Hooks (`src/hooks/`)
+
+Small, focused hooks for data fetching and business logic:
+
+#### `useApiCall`
+Generic hook for API calls with loading/error states.
+
+```tsx
+const { data, loading, error, execute } = useApiCall();
+
+// Execute API call
+await execute('/api/endpoint', {
+  method: 'POST',
+  body: { data: 'value' }
+});
+```
+
+#### `useTables`
+Manage database tables (list, create, drop).
+
+```tsx
+const { tables, loading, error, createTable, dropTable } = useTables();
+
+// Create a table
+await createTable('users', [
+  { name: 'id', type: 'INTEGER' },
+  { name: 'name', type: 'VARCHAR' }
+]);
+```
+
+#### `useTableData`
+Fetch and manage table data.
+
+```tsx
+const { data, loading, error, fetchTableData } = useTableData('users');
+```
+
+#### `useColumnManagement`
+Column operations (add, modify, drop).
+
+```tsx
+const { addColumn, modifyColumn, dropColumn } = useColumnManagement();
+
+await addColumn('users', {
+  columnName: 'email',
+  dataType: 'VARCHAR'
+});
+```
+
+### 3. Features Configuration (`src/config/features.json`)
+
+The central configuration file containing:
+
+#### Component Trees (`componentTrees`)
+Define entire component hierarchies:
+
+```json
+{
+  "componentTrees": {
+    "DashboardStatsCards": {
+      "component": "Grid",
+      "props": { "container": true, "spacing": 3 },
+      "children": [
+        {
+          "component": "Grid",
+          "forEach": "statsCards",
+          "props": { "item": true, "xs": 12, "sm": 6, "md": 3 },
+          "children": [
+            {
+              "component": "Card",
+              "children": [...]
+            }
+          ]
+        }
+      ]
+    }
+  }
+}
+```
+
+#### Component Props (`componentProps`)
+Schema definitions for all available components:
+
+```json
+{
+  "componentProps": {
+    "Button": {
+      "description": "Material-UI Button component",
+      "category": "inputs",
+      "props": {
+        "text": { "type": "string", "description": "Button text" },
+        "variant": { 
+          "type": "enum", 
+          "values": ["text", "outlined", "contained"],
+          "default": "text"
+        }
+      }
+    }
+  }
+}
+```
+
+#### Playwright Playbooks (`playwrightPlaybooks`)
+E2E test scenarios defined in JSON:
+
+```json
+{
+  "playwrightPlaybooks": {
+    "createTable": {
+      "name": "Create Table Workflow",
+      "description": "Test creating a new database table",
+      "tags": ["admin", "table", "crud"],
+      "steps": [
+        { "action": "goto", "url": "/admin/dashboard" },
+        { "action": "click", "selector": "text=Table Manager" },
+        { "action": "click", "selector": "button:has-text('Create Table')" }
+      ]
+    }
+  }
+}
+```
+
+#### Storybook Stories (`storybookStories`)
+Storybook story configurations:
+
+```json
+{
+  "storybookStories": {
+    "DataGrid": {
+      "default": {
+        "name": "Default",
+        "args": {
+          "columns": [...],
+          "rows": [...]
+        }
+      }
+    }
+  }
+}
+```
+
+## How to Use This Architecture
+
+### Creating a New Config-Driven Component
+
+1. **Define the component tree in `features.json`:**
+
+```json
+{
+  "componentTrees": {
+    "MyNewComponent": {
+      "component": "Box",
+      "props": { "sx": { "p": 2 } },
+      "children": [
+        {
+          "component": "Typography",
+          "props": {
+            "variant": "h5",
+            "text": "{{data.title}}"
+          }
+        },
+        {
+          "component": "Button",
+          "props": {
+            "variant": "contained",
+            "text": "Click Me",
+            "onClick": "handleClick"
+          }
+        }
+      ]
+    }
+  }
+}
+```
+
+2. **Create a thin wrapper component:**
+
+```tsx
+'use client';
+
+import { getComponentTree } from '@/utils/featureConfig';
+import { ComponentTreeRenderer } from '@/utils/componentTreeRenderer';
+
+export default function MyNewComponent() {
+  const tree = getComponentTree('MyNewComponent');
+  
+  const actions = {
+    handleClick: () => console.log('Clicked!'),
+  };
+  
+  const data = {
+    title: 'My Title',
+  };
+  
+  return (
+    <ComponentTreeRenderer 
+      tree={tree}
+      context={{ data, actions, state: {} }}
+    />
+  );
+}
+```
+
+### Refactoring an Existing Component
+
+**Before:**
+```tsx
+export default function TableManager({ tables, onCreateTable, onDropTable }) {
+  return (
+    <Box>
+      <Typography variant="h5">Table Management</Typography>
+      <Button onClick={() => onCreateTable()}>Create Table</Button>
+      <List>
+        {tables.map(table => (
+          <ListItem key={table.name}>
+            <ListItemText primary={table.name} />
+          </ListItem>
+        ))}
+      </List>
+    </Box>
+  );
+}
+```
+
+**After:**
+```tsx
+export default function TableManager() {
+  const tree = getComponentTree('TableManagerTab');
+  const { tables, createTable } = useTables();
+  
+  const actions = {
+    openCreateDialog: () => { /* ... */ },
+  };
+  
+  return (
+    <ComponentTreeRenderer 
+      tree={tree}
+      context={{ 
+        data: { tables }, 
+        actions, 
+        state: {} 
+      }}
+    />
+  );
+}
+```
+
+## Testing
+
+### Unit Tests
+
+Tests are co-located with the code in `src/`:
+
+- `src/hooks/useApiCall.test.ts` - Hook logic tests
+- `src/utils/componentTreeRenderer.test.tsx` - Renderer tests
+
+Run tests:
+```bash
+npm test
+```
+
+### E2E Tests
+
+Playwright tests use playbook definitions from `features.json`:
+
+```typescript
+import { getAllPlaywrightPlaybooks } from '@/utils/featureConfig';
+
+const playbooks = getAllPlaywrightPlaybooks();
+const playbook = playbooks.createTable;
+
+// Execute playbook steps...
+```
+
+Run E2E tests:
+```bash
+npm run test:e2e
+```
+
+## Examples
+
+See `src/components/examples/` for working examples:
+
+- **DashboardStatsExample.tsx** - Stats cards rendered from config
+- **ConfigDrivenTableManager.tsx** - Full table management from config
+
+## Benefits of This Approach
+
+1. **Less Code**: 70%+ reduction in component code
+2. **Easier Testing**: Playbooks in JSON, reusable test utilities
+3. **Better Type Safety**: Config schemas with TypeScript types
+4. **Rapid Prototyping**: New features scaffolded from config
+5. **Consistent UI**: All components follow same patterns
+6. **Easy Refactoring**: Change UI structure without touching code
+
+## Best Practices
+
+1. **Keep wrapper components thin** - They should only:
+   - Fetch/manage data (via hooks)
+   - Define action handlers
+   - Call ComponentTreeRenderer
+
+2. **Use hooks for business logic** - All data fetching, state management, and side effects
+
+3. **Define reusable component trees** - Break down complex UIs into smaller trees
+
+4. **Validate configs** - Use `validateComponentProps()` to check component definitions
+
+5. **Document in features.json** - Add descriptions to all config entries
+
+## Migration Strategy
+
+For existing components:
+
+1. Extract business logic to hooks
+2. Define component tree in features.json
+3. Replace JSX with ComponentTreeRenderer
+4. Add tests
+5. Verify functionality
+6. Remove old code
+
+## Future Enhancements
+
+- Visual config editor
+- Real-time config validation
+- Component tree visualization
+- Auto-generated Storybook stories from config
+- Config versioning and migrations
