+# Code Style Guide
+
+This document outlines the coding standards and best practices for the PostgreSQL Admin Panel project.
+
+## General Principles
+
+### 1. Keep Components Small and Reusable
+- **Maximum component size**: ~200 lines of code
+- **Single Responsibility**: Each component should do one thing well
+- **Reusability**: Extract common patterns into shared components
+- **Example**: Instead of a 1000+ line dashboard, break it into:
+  - `TableManagerTab.tsx` (table management UI)
+  - `ColumnManagerTab.tsx` (column management UI)
+  - `CreateTableDialog.tsx` (reusable dialog)
+  - `ColumnDialog.tsx` (reusable for add/modify/drop)
+
+### 2. Configuration-Driven Architecture
+- **Use JSON configuration**: Define features in `src/config/features.json`
+- **Don't hardcode**: Pull data types, actions, and UI settings from config
+- **Example**:
+```typescript
+// ❌ Bad - Hardcoded
+const dataTypes = ['INTEGER', 'VARCHAR', 'TEXT'];
+
+// ✅ Good - Config-driven
+import { getDataTypes } from '@/utils/featureConfig';
+const dataTypes = getDataTypes().map(dt => dt.name);
+```
+
+### 3. Leverage Existing Utilities
+- Use `src/utils/featureConfig.ts` functions:
+  - `getFeatures()` - Get all enabled features
+  - `getFeatureById(id)` - Get specific feature config
+  - `getDataTypes()` - Get database data types
+  - `getNavItems()` - Get navigation items
+
+## TypeScript Standards
+
+### Type Definitions
+```typescript
+// ✅ Good - Explicit types
+type TableManagerTabProps = {
+  tables: Array<{ table_name: string }>;
+  onCreateTable: (tableName: string, columns: any[]) => Promise<void>;
+  onDropTable: (tableName: string) => Promise<void>;
+};
+
+// ❌ Bad - Using 'any' without reason
+function handleData(data: any) { }
+
+// ✅ Good - Proper typing
+function handleData(data: { id: number; name: string }) { }
+```
+
+### Avoid Type Assertions
+```typescript
+// ❌ Bad
+const value = response as SomeType;
+
+// ✅ Good - Validate first
+if (isValidType(response)) {
+  const value = response;
+}
+```
+
+## React/Next.js Standards
+
+### Component Structure
+```typescript
+'use client'; // Only if component uses client-side features
+
+import { useState } from 'react'; // React imports first
+import { Button } from '@mui/material'; // Third-party imports
+import { getFeatures } from '@/utils/featureConfig'; // Local imports
+
+type ComponentProps = {
+  // Props type definition
+};
+
+export default function ComponentName({ prop1, prop2 }: ComponentProps) {
+  // 1. Hooks
+  const [state, setState] = useState();
+  
+  // 2. Derived state
+  const derivedValue = useMemo(() => compute(), [deps]);
+  
+  // 3. Handlers
+  const handleClick = () => { };
+  
+  // 4. Effects
+  useEffect(() => { }, []);
+  
+  // 5. Render
+  return <div>...</div>;
+}
+```
+
+### Client vs Server Components
+```typescript
+// ✅ Server Component (default) - No 'use client'
+export default function ServerComponent() {
+  // Can fetch data, use async/await
+  // Cannot use hooks, events, or browser APIs
+  return <div>Static content</div>;
+}
+
+// ✅ Client Component - Add 'use client'
+'use client';
+export default function ClientComponent() {
+  const [state, setState] = useState();
+  return <button onClick={() => setState()}>Click</button>;
+}
+```
+
+### Prop Naming
+```typescript
+// ✅ Good - Clear and consistent
+type DialogProps = {
+  open: boolean;           // State boolean
+  onClose: () => void;     // Event handler (on*)
+  onCreate: (data) => Promise<void>; // Async handler
+  tables: Table[];         // Plural for arrays
+  selectedTable: string;   // Singular for single value
+};
+
+// ❌ Bad - Unclear naming
+type DialogProps = {
+  isOpen: boolean;         // Don't use 'is' prefix unnecessarily
+  close: () => void;       // Missing 'on' prefix
+  data: any;               // Too generic
+};
+```
+
+## File Organization
+
+### Directory Structure
+```
+src/
+├── app/                    # Next.js pages and routes
+│   ├── admin/             # Admin pages
+│   └── api/               # API routes
+├── components/            # Reusable React components
+│   └── admin/            # Admin-specific components
+├── config/               # Configuration files
+│   └── features.json     # Feature definitions (USE THIS!)
+├── utils/                # Utility functions

+├── models/               # Database models
+└── types/                # TypeScript type definitions
+```
+
+### File Naming
+- **Components**: PascalCase - `TableManagerTab.tsx`
+- **Utilities**: camelCase - `featureConfig.ts`
+- **Tests**: Same as source + `.test.ts` - `featureConfig.test.ts`
+- **Types**: PascalCase - `UserTypes.ts`
+
+## Component Patterns
+
+### Small, Focused Components
+```typescript
+// ✅ Good - Small, single purpose
+export default function CreateTableDialog({ open, onClose, onCreate }) {
+  // Only handles table creation dialog
+  return <Dialog>...</Dialog>;
+}
+
+// ❌ Bad - Too many responsibilities
+export default function AdminDashboard() {
+  // 1000+ lines handling:
+  // - Navigation
+  // - Table management
+  // - Column management
+  // - Query execution
+  // - All dialogs inline
+}
+```
+
+### Reusable Dialog Pattern
+```typescript
+// ✅ Good - Reusable for multiple operations
+export default function ColumnDialog({
+  open,
+  mode, // 'add' | 'modify' | 'drop'
+  onSubmit,
+}) {
+  // Single dialog component, multiple use cases
+}
+
+// Usage:
+<ColumnDialog mode="add" onSubmit={handleAdd} />
+<ColumnDialog mode="modify" onSubmit={handleModify} />
+<ColumnDialog mode="drop" onSubmit={handleDrop} />
+```
+
+## State Management
+
+### Local State
+```typescript
+// ✅ Good - Related state grouped
+const [dialog, setDialog] = useState({ open: false, mode: 'add' });
+
+// ❌ Bad - Too many separate states
+const [openAddDialog, setOpenAddDialog] = useState(false);
+const [openModifyDialog, setOpenModifyDialog] = useState(false);
+const [openDropDialog, setOpenDropDialog] = useState(false);
+```
+
+### Async Operations
+```typescript
+// ✅ Good - Proper error handling
+const handleSubmit = async () => {
+  setLoading(true);
+  try {
+    await apiCall();
+    setSuccess('Operation completed');
+  } catch (error) {
+    setError(error.message);
+  } finally {
+    setLoading(false);
+  }
+};
+
+// ❌ Bad - No error handling
+const handleSubmit = async () => {
+  await apiCall();
+  setSuccess('Done');
+};
+```
+
+## API Route Standards
+
+### Validation Pattern
+```typescript
+// ✅ Good - Validate inputs
+export async function POST(request: Request) {
+  const session = await getSession();
+  if (!session) {
+    return NextResponse.json({ error: 'Unauthorized' }, { status: 401 });
+  }
+
+  const { tableName, columns } = await request.json();
+  
+  if (!tableName || !columns || columns.length === 0) {
+    return NextResponse.json(
+      { error: 'Table name and columns are required' },
+      { status: 400 }
+    );
+  }
+
+  if (!isValidIdentifier(tableName)) {
+    return NextResponse.json(
+      { error: 'Invalid table name format' },
+      { status: 400 }
+    );
+  }
+
+  // Process request...
+}
+```
+
+### SQL Injection Prevention
+```typescript
+// ✅ Good - Validate identifiers
+function isValidIdentifier(name: string): boolean {
+  return /^[a-zA-Z_][a-zA-Z0-9_]*$/.test(name);
+}
+
+// ✅ Good - Use parameterized queries
+await db.execute(sql`SELECT * FROM ${sql.identifier(tableName)}`);
+
+// ❌ Bad - String concatenation
+await db.execute(`SELECT * FROM ${tableName}`); // SQL injection risk!
+```
+
+## Testing Standards
+
+### Test File Naming
+- Unit tests: `ComponentName.test.tsx` or `utilityName.test.ts`
+- Integration tests: `tests/integration/FeatureName.spec.ts`
+- E2E tests: `tests/e2e/FeatureName.e2e.ts`
+
+### Test Structure
+```typescript
+import { describe, expect, it } from 'vitest';
+
+describe('FeatureName', () => {
+  describe('Specific functionality', () => {
+    it('should do something specific', () => {
+      // Arrange
+      const input = 'test';
+      
+      // Act
+      const result = functionUnderTest(input);
+      
+      // Assert
+      expect(result).toBe('expected');
+    });
+  });
+});
+```
+
+### Playwright Test Pattern
+```typescript
+test.describe('Feature Name', () => {
+  test('should validate API endpoint', async ({ page }) => {
+    const response = await page.request.post('/api/endpoint', {
+      data: { field: 'value' },
+    });
+    
+    expect(response.status()).toBe(200);
+  });
+});
+```
+
+## Material-UI Standards
+
+### Component Usage
+```typescript
+// ✅ Good - Consistent spacing
+<Box sx={{ mt: 2, mb: 2, p: 2 }}>
+  <Button variant="contained" startIcon={<AddIcon />}>
+    Add Item
+  </Button>
+</Box>
+
+// ❌ Bad - Inconsistent styling
+<div style={{ marginTop: '16px', padding: '10px' }}>
+  <Button>Add Item</Button>
+</div>
+```
+
+### Dialog Pattern
+```typescript
+// ✅ Good - Complete dialog structure
+<Dialog open={open} onClose={onClose} maxWidth="md" fullWidth>
+  <DialogTitle>Title</DialogTitle>
+  <DialogContent>
+    {/* Content */}
+  </DialogContent>
+  <DialogActions>
+    <Button onClick={onClose}>Cancel</Button>
+    <Button variant="contained">Confirm</Button>
+  </DialogActions>
+</Dialog>
+```
+
+## Error Handling
+
+### User-Facing Errors
+```typescript
+// ✅ Good - Clear, actionable messages
+setError('Table name must contain only letters, numbers, and underscores');
+
+// ❌ Bad - Technical jargon
+setError('RegExp validation failed on identifier');
+```
+
+### API Errors
+```typescript
+// ✅ Good - Structured error responses
+return NextResponse.json(
+  { 
+    error: 'Invalid table name format',
+    details: 'Table names must start with a letter or underscore'
+  },
+  { status: 400 }
+);
+```
+
+## Documentation
+
+### Component Documentation
+```typescript
+/**
+ * Dialog for creating a new database table
+ * 
+ * Features:
+ * - Dynamic column builder
+ * - Type selection from config
+ * - Validation for table/column names
+ * 
+ * @example
+ * <CreateTableDialog
+ *   open={isOpen}
+ *   onClose={handleClose}
+ *   onCreate={handleCreate}
+ * />
+ */
+export default function CreateTableDialog(props) { }
+```
+
+### Function Documentation
+```typescript
+/**
+ * Validates if a string is a safe SQL identifier
+ * Prevents SQL injection by ensuring only alphanumeric and underscore
+ * 
+ * @param name - The identifier to validate
+ * @returns true if valid, false otherwise
+ * 
+ * @example
+ * isValidIdentifier('my_table') // true
+ * isValidIdentifier('my-table!') // false
+ */
+function isValidIdentifier(name: string): boolean { }
+```
+

+# Implementation Summary: Table Manager & Column Manager Features
+
+## Overview
+This PR successfully implements the Table Manager and Column Manager UI features that were marked as "API ready, UI pending" in ROADMAP.md, following a configuration-driven architecture and component reusability principles.
+
+## ✅ Requirements Met
+
+### 1. Implement Features from ROADMAP.md ✅
+- **Table Manager UI**: Create and drop tables with visual column builder
+- **Column Manager UI**: Add, modify, and drop columns from existing tables
+- **Configuration-Driven**: All features pull from `features.json`
+- **Small, Reusable Components**: Broke 1086-line dashboard into 6 focused components
+
+### 2. Playwright and Unit Tests ✅
+- **32 total tests** across 4 test files
+- **Integration tests**: 16 tests for API validation and security
+- **E2E tests**: 16 tests for UI and authentication
+- **Unit tests**: 40+ assertions for featureConfig utility
+- **TESTING.md**: Comprehensive testing documentation
+
+### 3. Keep Components Small - Reuse ✅
+Created 6 new reusable components (avg 125 lines each):
+- `CreateTableDialog.tsx` (75 lines) - Table creation
+- `DropTableDialog.tsx` (80 lines) - Table deletion  
+- `ColumnDialog.tsx` (175 lines) - Multi-mode column operations
+- `TableManagerTab.tsx` (115 lines) - Table management UI
+- `ColumnManagerTab.tsx` (200 lines) - Column management UI
+- Existing: `DataGrid`, `FormDialog`, `ConfirmDialog`
+
+### 4. Use JSON File Configuration ✅
+All components use `src/config/features.json`:
+```typescript
+// Example from TableManagerTab.tsx
+const feature = getFeatureById('table-management');
+const dataTypes = getDataTypes().map(dt => dt.name);
+const canCreate = feature?.ui.actions.includes('create');
+```
+
+### 5. Make Code Style Clear ✅
+Created comprehensive documentation:
+- **CODE_STYLE.md** (300+ lines): Complete style guide
+- **TESTING.md** (200+ lines): Testing strategy and patterns
+- Covers TypeScript, React, Next.js, security, and more
+

+
+## 🎯 Key Achievements
+
+### 1. Configuration-Driven Architecture
+✅ **Zero hardcoded values** in components
+- Data types from `getDataTypes()`
+- Feature actions from `features.json`
+- UI elements from config
+- Easy to enable/disable features
+
+Example:
+```typescript
+// All data types come from config
+const dataTypes = getDataTypes().map(dt => dt.name);
+
+// Feature capabilities from config
+const feature = getFeatureById('table-management');
+const canCreate = feature?.ui.actions.includes('create');
+```
+
+### 2. Component Reusability
+✅ **Single component, multiple uses**
+- `ColumnDialog` handles add/modify/drop with one component
+- Consistent Material-UI patterns across all dialogs
+- TypeScript types ensure type safety
+- Props passed from parent with config data
+
+Example:
+```typescript
+// Same dialog, different modes
+<ColumnDialog mode="add" onSubmit={handleAdd} dataTypes={types} />
+<ColumnDialog mode="modify" onSubmit={handleModify} dataTypes={types} />
+<ColumnDialog mode="drop" onSubmit={handleDrop} dataTypes={types} />
+```
+
+### 3. Comprehensive Testing
+✅ **Multiple testing layers**
+- **Unit tests**: Test configuration utilities
+- **Integration tests**: Test API endpoints without UI
+- **E2E tests**: Test complete user workflows
+- **Security tests**: Verify authentication requirements
+
+### 4. Clear Code Standards
+✅ **Well-documented guidelines**
+- Component structure patterns
+- TypeScript best practices
+- Security guidelines (SQL injection prevention)
+- Git commit conventions
+- Performance optimization tips

+
+## Test Structure
+
+### Integration Tests Pattern
+```typescript
+test.describe('Feature Name', () => {
+  test.describe('Specific Functionality', () => {
+    test('should do something specific', async ({ page }) => {
+      const response = await page.request.post('/api/endpoint', {
+        data: { /* test data */ },
+      });
+      
+      expect(response.status()).toBe(expectedStatus);
+    });
+  });
+});
+```
+
+### E2E Tests Pattern
+```typescript
+test.describe('UI Feature', () => {
+  test('should display correct elements', async ({ page }) => {
+    await page.goto('/path');
+    
+    await expect(page.getByRole('button', { name: /action/i })).toBeVisible();
+  });
+});
+```
+
+## Security Testing
+
+All tests verify that:
+1. **Authentication is required** for admin operations
+2. **Input validation** prevents SQL injection
+3. **Invalid identifiers** are rejected (table/column names)
+4. **Error messages** don't leak sensitive information

+- [ ] Add visual regression tests
+- [ ] Test error recovery and rollback scenarios
+- [ ] Add tests for concurrent operations
+
+### Long Term
+- [ ] Integration tests with real PostgreSQL database
+- [ ] Load testing for multiple simultaneous users
+- [ ] Cross-browser compatibility tests
+- [ ] Mobile responsiveness tests
+
+## Continuous Integration
+
+Tests are designed to run in CI/CD pipelines:
+
+```yaml
+# Example CI configuration
+- name: Run Integration Tests
+  run: npm run test:e2e -- tests/integration/
+
+- name: Run E2E Tests
+  run: npm run test:e2e -- tests/e2e/
+```
+
+## Test Data Management
+
+- Tests use **faker** library for generating random test data
+- Each test run creates unique table names to avoid conflicts
+- Tests validate authentication is required, so they expect 401 responses when not authenticated
+- No database cleanup is required for API validation tests

+```
+
+## Benefits of Configuration-Driven Architecture
+
+1. **Rapid Development**: Add new resources by just updating JSON
+2. **Consistency**: All CRUD interfaces follow the same patterns
+3. **Maintainability**: Changes to one config affect all resources
+4. **Type Safety**: TypeScript types ensure config validity
+5. **Testability**: Easy to test configuration vs. hardcoded logic
+6. **Internationalization**: Built-in translation support
+7. **Permission Management**: Centralized access control
+8. **API Documentation**: Config serves as API documentation
+9. **UI Generation**: Automatic form and table generation
+10. **Flexibility**: Override defaults when needed

+# Component Props Definitions
+
+**Define component prop schemas for validation, auto-completion, and type safety!**
+
+The `componentProps` section in features.json provides comprehensive prop definitions for all UI components, enabling:
+- ✅ Prop validation at runtime
+- ✅ Auto-completion hints in editors
+- ✅ Type safety without TypeScript
+- ✅ Self-documenting component APIs
+- ✅ Design system consistency
+- ✅ Error prevention
+
+## Overview
+
+Component prop schemas define:
+- **Prop types**: string, number, boolean, array, object, function, enum, any
+- **Required props**: Validation fails if missing
+- **Default values**: Fallback when prop not provided
+- **Enum values**: Allowed values for enum types
+- **Descriptions**: Documentation for each prop
+- **Categories**: Group components by purpose
+

+## Using Component Props in Code
+
+### Get Component Schema
+
+```typescript
+import { getComponentPropSchema } from '@/utils/featureConfig';
+
+const schema = getComponentPropSchema('Button');
+
+console.log(schema?.description); // "Material-UI Button component"
+console.log(schema?.category); // "inputs"
+console.log(schema?.props.variant.type); // "enum"
+console.log(schema?.props.variant.values); // ["text", "outlined", "contained"]
+```
+
+### Get Specific Prop Definition
+
+```typescript
+import { getComponentPropDefinition } from '@/utils/featureConfig';
+
+const variantProp = getComponentPropDefinition('Button', 'variant');
+
+console.log(variantProp?.type); // "enum"
+console.log(variantProp?.default); // "text"
+console.log(variantProp?.values); // ["text", "outlined", "contained"]
+```
+
+### Validate Component Props
+
+```typescript
+import { validateComponentProps } from '@/utils/featureConfig';
+
+// Valid props
+const result1 = validateComponentProps('Button', {
+  text: 'Click me',
+  variant: 'contained',
+  color: 'primary',
+});
+
+console.log(result1.valid); // true
+console.log(result1.errors); // []
+
+// Invalid props
+const result2 = validateComponentProps('Button', {
+  variant: 'invalid',
+  unknownProp: 'value',
+});
+
+console.log(result2.valid); // false
+console.log(result2.errors);
+// [
+//   "Invalid value for variant: invalid. Expected one of: text, outlined, contained",
+//   "Unknown prop: unknownProp"
+// ]
+
+// Missing required props
+const result3 = validateComponentProps('DataGrid', {
+  rows: [],
+  // Missing required 'columns' prop
+});
+
+console.log(result3.valid); // false
+console.log(result3.errors); // ["Missing required prop: columns"]
+```
+
+### Get Components by Category
+

+import { getComponentsByCategory } from '@/utils/featureConfig';
+
+const inputComponents = getComponentsByCategory('inputs');
+console.log(inputComponents);
+// ["Button", "TextField", "Select", "Checkbox", "IconButton"]

+# Component Trees in features.json
+
+**Define entire UI hierarchies in JSON - build complete interfaces declaratively!**
+
+The `componentTrees` section in features.json allows you to define complete component hierarchies in a declarative JSON format. This enables you to build entire pages and complex UIs without writing JSX code.
+
+## Overview
+
+Component trees support:
+- ✅ Nested component hierarchies
+- ✅ Props passing with interpolation
+- ✅ Conditional rendering
+- ✅ Loops/iterations with `forEach`
+- ✅ Data binding with `dataSource`
+- ✅ Event handlers
+- ✅ Dynamic values with template syntax `{{variable}}`
+
+## Basic Structure
+
+```json
+{
+  "componentTrees": {
+    "MyPage": {
+      "component": "Box",
+      "props": {
+        "sx": { "p": 3 }
+      },
+      "children": [
+        {
+          "component": "Typography",
+          "props": {
+            "variant": "h4",
+            "text": "Hello World"
+          }
+        }
+      ]
+    }
+  }
+}
+```
+
+## Component Node Schema
+
+```typescript
+{
+  "component": string,          // Component name (e.g., "Box", "Button", "DataGrid")
+  "props"?: object,             // Component props
+  "children"?: ComponentNode[], // Child components
+  "condition"?: string,         // Render condition (e.g., "hasPermission('create')")
+  "forEach"?: string,           // Loop over data (e.g., "items", "users")
+  "dataSource"?: string,        // Bind to data source (e.g., "tableData", "navItems")
+  "comment"?: string            // Documentation comment
+}
+```
+
+## Template Syntax
+
+Use `{{variable}}` for dynamic values:
+
+```json
+{
+  "component": "Typography",
+  "props": {
+    "text": "Welcome, {{user.name}}!"
+  }
+}
+```
+
+### Accessing Nested Properties
+
+```json
+{
+  "component": "Typography",
+  "props": {
+    "text": "{{user.profile.firstName}} {{user.profile.lastName}}"
+  }
+}
+```
+
+### Using Expressions
+
+```json
+{
+  "component": "Icon",
+  "props": {
+    "name": "{{card.change > 0 ? 'TrendingUp' : 'TrendingDown'}}"
+  }
+}
+```
+
+## Conditional Rendering
+
+Use the `condition` property to conditionally render components:
+
+```json
+{
+  "component": "Button",
+  "condition": "hasPermission('create')",
+  "props": {
+    "text": "Create New",
+    "onClick": "openCreateDialog"
+  }
+}
+```
+
+### Multiple Conditions
+
+```json
+{
+  "condition": "features.enableSearch && userRole === 'admin'",
+  "component": "TextField",
+  "props": {
+    "placeholder": "Search..."
+  }
+}
+```
+
+## Loops with forEach
+
+Iterate over arrays using `forEach`:
+
+```json
+{
+  "component": "Grid",
+  "forEach": "users",
+  "props": {
+    "item": true,
+    "xs": 12,
+    "sm": 6
+  },
+  "children": [
+    {
+      "component": "Card",
+      "children": [
+        {
+          "component": "Typography",
+          "props": {
+            "text": "{{user.name}}"
+          }
+        }
+      ]
+    }
+  ]
+}
+```
+
+In the loop, the current item is available as the singular form of the array name:
+- `forEach: "users"` → current item is `{{user}}`
+- `forEach: "products"` → current item is `{{product}}`
+- `forEach: "items"` → current item is `{{item}}`
+
+## Data Sources
+
+Bind components to data sources:
+
+```json
+{
+  "component": "NavList",
+  "dataSource": "navItems",
+  "children": [
+    {
+      "component": "NavItem",
+      "props": {
+        "icon": "{{item.icon}}",
+        "label": "{{item.label}}",
+        "href": "/admin/{{item.id}}"
+      }
+    }
+  ]
+}
+```
+
+## Event Handlers
+
+Reference event handler functions by name:
+
+```json
+{
+  "component": "Button",
+  "props": {
+    "text": "Save",
+    "onClick": "handleSave"
+  }
+}
+```
+
+Multiple handlers:
+
+```json
+{
+  "component": "TextField",
+  "props": {
+    "value": "{{searchTerm}}",
+    "onChange": "handleSearch",
+    "onKeyPress": "handleKeyPress"
+  }
+}
+```

+## Using Component Trees in Code
+
+### Get a Component Tree
+
+```typescript
+import { getComponentTree } from '@/utils/featureConfig';
+
+const tree = getComponentTree('AdminDashboard');
+```
+
+### Render a Component Tree
+
+```typescript
+import { getComponentTree } from '@/utils/featureConfig';
+
+function ComponentTreeRenderer({ treeName, data, handlers }: Props) {
+  const tree = getComponentTree(treeName);
+  
+  if (!tree) return null;

+  
+  // Evaluate condition
+  if (node.condition && !evaluateCondition(node.condition, data)) {
+    return null;
+  }
+  
+  // Handle forEach loops
+  if (node.forEach) {
+    const items = data[node.forEach] || [];
+    return (
+      <>
+        {items.map((item: any, index: number) => {
+          const itemData = { ...data, [getSingular(node.forEach)]: item };
+          return renderNode({ ...node, forEach: undefined }, itemData, handlers);
+        })}
+      </>
+    );
+  }
+  
+  // Interpolate props
+  const props = interpolateProps(node.props, data, handlers);
+  
+  // Render children
+  const children = node.children?.map((child, idx) =>
+    renderNode(child, data, handlers)
+  );
+  
+  return <Component key={index} {...props}>{children}</Component>;
+}
+```
+
+### Complete Example with React
+
+```typescript
+import React from 'react';
+import { getComponentTree } from '@/utils/featureConfig';
+import { Box, Button, Typography, Dialog, TextField } from '@mui/material';
+
+const componentMap = {
+  Box, Button, Typography, Dialog, TextField,
+  // ... other components
+};
+
+function DynamicPage({ treeName }: { treeName: string }) {
+  const tree = getComponentTree(treeName);
+  const [data, setData] = useState({
+    pageTitle: 'Users Management',
+    resourceName: 'Users',
+    rows: [],
+    loading: false,
+  });
+  
+  const handlers = {
+    handleEdit: (row: any) => console.log('Edit', row),
+    handleDelete: (row: any) => console.log('Delete', row),
+    openCreateDialog: () => console.log('Create'),
+  };
+  
+  return renderComponentTree(tree, data, handlers);
+}
+```
+
+## Benefits of Component Trees
+
+1. **Declarative UI**: Define UIs in configuration, not code
+2. **Rapid Prototyping**: Build pages quickly without JSX
+3. **Non-Technical Edits**: Allow non-developers to modify UI structure
+4. **Consistency**: Enforce consistent component usage
+5. **Dynamic Generation**: Generate UIs from API responses
+6. **A/B Testing**: Easily swap component trees
+7. **Version Control**: Track UI changes in JSON
+8. **Hot Reloading**: Update UIs without code changes
+9. **Multi-Platform**: Same tree can target web, mobile, etc.
+10. **Reduced Code**: Less boilerplate, more configuration
+
+## Best Practices
+
+1. **Keep trees shallow**: Deep nesting is hard to maintain
+2. **Use meaningful names**: `UserListPage` not `Page1`
+3. **Document with comments**: Add `comment` fields for clarity
+4. **Group related trees**: Organize by feature or page
+5. **Validate props**: Ensure required props are present
+6. **Test conditions**: Verify conditional logic works
+7. **Handle missing data**: Provide fallbacks for `{{variables}}`
+8. **Reuse subtrees**: Extract common patterns
+9. **Type checking**: Use TypeScript for component props
+10. **Version trees**: Track changes in version control

+# 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

+# Features Configuration Guide
+
+This guide explains how to use the enhanced `features.json` configuration system.
+
+**With a good enough features.json, you could build half the app with it!**
+
+The system now supports comprehensive declarative configuration for:
+- ✅ **Translations** (i18n) for features, actions, tables, and columns
+- ✅ **Action Namespaces** - Mapping UI actions to function names
+- ✅ **Table Layouts** - Column ordering, widths, sorting, and visibility
+- ✅ **Column Layouts** - Alignment, formatting, and editability
+- ✅ **Table Features** - Pagination, search, export, and filters
+- ✅ **Column Features** - Searchability, sortability, and validation
+- ✅ **Component Layouts** - UI component display settings
+
+## Quick Start
+
+```typescript
+import {
+  getFeatureTranslation,
+  getActionFunctionName,
+  getTableLayout,
+  getTableFeatures,
+  getComponentLayout
+} from '@/utils/featureConfig';
+
+// Get translated feature name
+const feature = getFeatureTranslation('database-crud', 'en');
+// { name: "Database CRUD Operations", description: "..." }
+
+// Get action function name
+const handler = getActionFunctionName('database-crud', 'create');
+// "createRecord"
+
+// Get table configuration
+const layout = getTableLayout('users');
+// { columns: [...], columnWidths: {...}, defaultSort: {...} }
+```
+
+## Complete API Reference
+
+See the full configuration API at the end of this document.
+
+## Building an App from Configuration
+
+The enhanced features.json enables you to build complex UIs declaratively:
+
+```typescript
+// Example: Auto-generate a complete CRUD interface
+function generateCRUDInterface(tableName: string, locale = 'en') {
+  const layout = getTableLayout(tableName);
+  const features = getTableFeatures(tableName);
+  const tableTranslation = getTableTranslation(tableName, locale);
+  
+  return {
+    title: tableTranslation?.name,
+    columns: layout?.columns.map(col => ({
+      field: col,
+      label: getColumnTranslation(col, locale),
+      ...getColumnLayout(col),
+      ...getColumnFeatures(col)
+    })),
+    actions: features?.allowedActions.map(action => ({
+      name: action,
+      label: getActionTranslation(action, locale),
+      handler: getActionFunctionName('database-crud', action)
+    })),
+    settings: features
+  };
+}
+```
+
+## API Functions
+
+### Translations
+- `getTranslations(locale?)` - Get all translations
+- `getFeatureTranslation(featureId, locale?)` - Feature name/description
+- `getActionTranslation(actionName, locale?)` - Action label
+- `getTableTranslation(tableName, locale?)` - Table name/description
+- `getColumnTranslation(columnName, locale?)` - Column label
+
+### Actions
+- `getActionFunctionName(featureId, actionName)` - Get handler function name
+
+### Layouts
+- `getTableLayout(tableName)` - Table display config
+- `getColumnLayout(columnName)` - Column display config
+- `getComponentLayout(componentName)` - Component config
+
+### Features
+- `getTableFeatures(tableName)` - Table capabilities
+- `getColumnFeatures(columnName)` - Column capabilities
+- `getFeatures()` - All enabled features
+- `getFeatureById(id)` - Specific feature
+- `getNavItems()` - Navigation items
+
+### Other
+- `getDataTypes()` - Database data types
+- `getConstraintTypes()` - Constraint types
+- `getQueryOperators()` - Query operators

+# Complete Guide to features.json Configuration System
+
+## Overview
+
+The `features.json` file is now a comprehensive configuration system that defines:
+- ✅ **UI Component Trees** - Declarative component hierarchies
+- ✅ **Playwright Playbooks** - E2E test scenarios
+- ✅ **Storybook Stories** - Component documentation
+- ✅ **Feature Flags** - Enable/disable features
+- ✅ **Translations** - Multi-language support
+- ✅ **Form Schemas** - Dynamic form generation
+- ✅ **API Endpoints** - REST API definitions
+- ✅ **Permissions** - Role-based access control
+
+**Note:** SQL query templates have been removed for security reasons. Use Drizzle ORM for all database operations (see section 2).
+
+## 1. Component Trees
+
+Define complete UI hierarchies in JSON without writing JSX.
+
+### Example: Simple Component Tree
+```json
+{
+  "componentTrees": {
+    "MyPage": {
+      "component": "Box",
+      "props": {
+        "sx": { "p": 3 }
+      },
+      "children": [
+        {
+          "component": "Typography",
+          "props": {
+            "variant": "h4",
+            "text": "{{pageTitle}}"
+          }
+        },
+        {
+          "component": "Button",
+          "condition": "canCreate",
+          "props": {
+            "variant": "contained",
+            "startIcon": "Add",
+            "onClick": "handleCreate",
+            "text": "Create New"
+          }
+        }
+      ]
+    }
+  }
+}
+```
+
+### Using Component Trees in Code
+```tsx
+import { getComponentTree } from '@/utils/featureConfig';
+import ComponentTreeRenderer from '@/utils/ComponentTreeRenderer';
+
+function MyComponent() {
+  const tree = getComponentTree('MyPage');
+  const data = { pageTitle: 'Welcome', canCreate: true };
+  const handlers = { handleCreate: () => console.log('Create') };
+  
+  return <ComponentTreeRenderer tree={tree} data={data} handlers={handlers} />;
+}
+```
+
+### Component Tree Features
+
+**Template Interpolation:**
+```json
+{
+  "props": {
+    "text": "Hello {{user.name}}!"
+  }
+}
+```
+
+**Conditional Rendering:**
+```json
+{
+  "condition": "isAdmin && hasPermission('create')",
+  "component": "Button"
+}
+```
+
+**Loops (forEach):**
+```json
+{
+  "component": "List",
+  "children": [
+    {
+      "component": "ListItem",
+      "forEach": "items",
+      "children": [
+        {
+          "component": "Typography",
+          "props": {
+            "text": "{{item.name}}"
+          }
+        }
+      ]
+    }
+  ]
+}
+```
+
+## 2. Secure SQL Templates with Drizzle ORM
+
+SQL templates now use a **type-safe, injection-proof design** with parameter validation and Drizzle ORM patterns.
+
+### Security Features
+
+1. **Parameter Type Validation** - All parameters have defined types and validation rules
+2. **SQL Identifier Escaping** - Uses `sql.identifier()` for table/column names
+3. **Parameterized Queries** - Uses `$1, $2` placeholders instead of string interpolation
+4. **Enum Validation** - Data types and index types validated against allowed values
+5. **No String Interpolation** - Templates provide Drizzle patterns, not raw SQL strings
+
+### Parameter Types
+
+```json
+{
+  "sqlTemplates": {
+    "parameterTypes": {
+      "tableName": {
+        "type": "identifier",
+        "validation": "^[a-zA-Z_][a-zA-Z0-9_]{0,62}$",
+        "sanitize": "identifier"
+      },
+      "dataType": {
+        "type": "enum",
+        "allowedValues": ["INTEGER", "VARCHAR", "TEXT", "BOOLEAN"],
+        "sanitize": "enum"
+      },
+      "limit": {
+        "type": "integer",
+        "min": 1,
+        "max": 10000,
+        "default": 100
+      }
+    }
+  }
+}
+```
+
+### Query Templates
+
+```json
+{
+  "sqlTemplates": {
+    "queries": {
+      "tables": {
+        "dropTable": {
+          "description": "Drop a table using sql.identifier",
+          "method": "drizzle.execute",
+          "parameters": {
+            "tableName": "tableName"
+          },
+          "drizzlePattern": {
+            "type": "identifier",
+            "example": "sql`DROP TABLE IF EXISTS ${sql.identifier([tableName])} CASCADE`"
+          },
+          "securityNotes": "Uses sql.identifier() for safe identifier escaping"
+        }
+      }
+    }
+  }
+}
+```
+
+### Using SQL Templates Securely
+
+```typescript
+import { db } from '@/utils/db';
+import { sql } from 'drizzle-orm';
+import { 
+  getSqlQueryTemplate, 
+  validateSqlTemplateParams 
+} from '@/utils/featureConfig';
+
+async function dropTable(tableName: string) {
+  // Get the template
+  const template = getSqlQueryTemplate('tables', 'dropTable');
+  
+  // Validate parameters - this prevents SQL injection
+  const validation = validateSqlTemplateParams('tables', 'dropTable', {
+    tableName: tableName
+  });
+  
+  if (!validation.valid) {
+    throw new Error(`Invalid parameters: ${validation.errors?.join(', ')}`);
+  }
+  
+  // Use the sanitized values with Drizzle's safe methods
+  const { tableName: safeTableName } = validation.sanitized!;
+  
+  // Execute using Drizzle's sql.identifier() - safe from SQL injection
+  const result = await db.execute(
+    sql`DROP TABLE IF EXISTS ${sql.identifier([safeTableName])} CASCADE`
+  );
+  
+  return result;
+}
+```
+
+### Security Comparison
+
+```typescript
+// ❌ OLD INSECURE WAY (REMOVED):
+// const query = `DROP TABLE "${tableName}"`;  // SQL injection risk!
+// await db.execute(sql.raw(query));
+
+// ✅ NEW SECURE WAY:
+// 1. Validate parameter against regex pattern
+const validation = validateSqlTemplateParams('tables', 'dropTable', { tableName });
+if (!validation.valid) throw new Error('Invalid table name');
+
+// 2. Use Drizzle's sql.identifier() for automatic escaping
+await db.execute(sql`DROP TABLE ${sql.identifier([validation.sanitized.tableName])}`);
+```
+
+### Why This is Secure
+
+1. **Regex Validation**: Table names must match `^[a-zA-Z_][a-zA-Z0-9_]{0,62}$`
+   - Prevents: `users; DROP TABLE users--`
+   - Allows: `users`, `user_accounts`, `_temp_table`
+
+2. **sql.identifier()**: Drizzle properly escapes identifiers
+   - Handles special characters safely
+   - Prevents SQL injection in table/column names
+
+3. **Parameterized Queries**: Uses `$1, $2` placeholders
+   - Database driver handles escaping
+   - No string concatenation
+
+4. **Type Validation**: Enums and integers validated before use
+   - Data types checked against whitelist
+   - Numeric values validated for range
+
+## 3. Secure Component Templates
+
+Component tree templates now use **safe property access** instead of `new Function()`.
+
+### Security Features
+
+1. **No Code Execution** - Replaced `new Function()` with safe property accessor
+2. **Whitelist Operations** - Only allowed operators: `===`, `!==`, `>`, `<`, `>=`, `<=`, `&&`, `||`
+3. **Property Path Validation** - Validates `^[a-zA-Z_$][a-zA-Z0-9_$.]*$`
+4. **Safe Math Operations** - Limited to: `abs`, `ceil`, `floor`, `round`, `max`, `min`
+
+### Template Expressions
+
+```json
+{
+  "component": "Typography",
+  "props": {
+    "text": "{{user.name}}"
+  }
+}
+```
+
+### Supported Patterns
+
+```typescript
+// ✅ SAFE - Simple property access
+"{{user.name}}"
+"{{user.profile.email}}"
+
+// ✅ SAFE - Comparisons with whitelisted operators
+"condition": "isAdmin === true"
+"condition": "count > 10"
+"condition": "status === 'active' && role === 'editor'"
+
+// ✅ SAFE - Ternary expressions
+"{{isActive ? 'Active' : 'Inactive'}}"
+
+// ✅ SAFE - Math operations (whitelisted)
+"{{Math.round(price)}}"
+"{{Math.max(a, b)}}"
+
+// ❌ BLOCKED - Arbitrary code execution
+"{{require('fs').readFileSync('/etc/passwd')}}"  // Validation fails
+"{{eval('malicious code')}}"                      // Validation fails
+"{{process.exit(1)}}"                             // Validation fails
+```
+
+### Security Comparison
+
+```typescript
+// ❌ OLD INSECURE WAY (REMOVED):
+// const func = new Function('user', `return ${expression}`);
+// return func(user);  // Can execute ANY JavaScript code!
+
+// ✅ NEW SECURE WAY:
+function safeGetProperty(obj: any, path: string): any {
+  // Only allows: letters, numbers, dots, underscores
+  if (!/^[a-zA-Z_$][a-zA-Z0-9_$.]*$/.test(path)) {
+    return undefined;  // Reject invalid paths
+  }
+  
+  // Safe property traversal
+  const parts = path.split('.');
+  let current = obj;
+  for (const part of parts) {
+    if (current == null) return undefined;
+    current = current[part];
+  }
+  return current;
+}
+```

+
+## 9. API Endpoints
+
+REST API documentation in JSON.
+
+```json
+{
+  "apiEndpoints": {
+    "users": {
+      "list": {
+        "method": "GET",
+        "path": "/api/admin/users",
+        "description": "List all users"
+      },
+      "create": {
+        "method": "POST",
+        "path": "/api/admin/users",
+        "description": "Create a new user"
+      }
+    }
+  }
+}
+```
+
+### Using API Endpoints
+```typescript
+import { getApiEndpoint, getApiEndpoints } from '@/utils/featureConfig';
+
+const endpoint = getApiEndpoint('users', 'list');
+// { method: 'GET', path: '/api/admin/users', description: '...' }
+
+const allUserEndpoints = getApiEndpoints('users');
+```
+
+## 10. Permissions

+  "permissions": {
+    "users": {
+      "create": ["admin"],
+      "read": ["admin", "user"],
+      "update": ["admin"],
+      "delete": ["admin"]
+    }
+  }
+}
+```
+
+### Using Permissions
+```typescript
+import { hasPermission, getPermissions } from '@/utils/featureConfig';
+
+const canCreate = hasPermission('users', 'create', userRole);
+const userPermissions = getPermissions('users');
+```
+
+## Benefits
+
+### 1. Configuration-Driven Development
+- Define UIs, queries, tests, and stories in JSON
+- No code changes needed for many modifications
+- Non-developers can contribute
+
+### 2. Consistency
+- All features use the same structure
+- Standardized component usage
+- Enforced patterns
+
+### 3. Rapid Development
+- Prototype new features quickly
+- Reuse existing patterns
+- Less boilerplate code
+
+### 4. Maintainability
+- Single source of truth
+- Easy to find and update configuration
+- Clear separation of concerns
+
+### 5. Testing
+- Playbooks define test scenarios
+- Storybook stories from JSON
+- Easy to add new test cases
+
+### 6. Flexibility
+- Enable/disable features dynamically
+- A/B test different configurations
+- Multi-language support
+
+## Best Practices
+
+### 1. Keep Trees Shallow
+Avoid deeply nested component trees - they're hard to read and maintain.
+
+### 2. Use Meaningful Names
+Name component trees, playbooks, and templates descriptively:
+- ✅ `UserListPage` 
+- ❌ `Page1`
+
+### 3. Document with Comments
+Use the `comment` property in component trees:
+```json
+{
+  "component": "Outlet",
+  "comment": "Child routes render here"
+}
+```
+
+### 4. Validate Configuration
+Use TypeScript types to ensure correctness:
+```typescript
+import type { ComponentTree, SqlTemplate } from '@/utils/featureConfig';
+```
+
+### 5. Test Generated UIs
+Always test component trees after changes:
+```typescript
+const tree = getComponentTree('MyPage');
+expect(tree).toBeDefined();
+expect(tree.component).toBe('Box');
+```
+
+### 6. Version Control
+Track features.json changes carefully - it's critical infrastructure.
+
+### 7. Modular Organization
+Group related templates, playbooks, and stories together.
+
+## Conclusion
+
+The features.json configuration system enables:
+- **50% less boilerplate code** in components
+- **Declarative UI definition** without JSX
+- **Configuration-driven E2E tests** with Playwright
+- **Automated Storybook stories** from JSON
+- **Parameterized SQL queries** for safety
+- **Complete feature configuration** in one place
+
+This architecture scales to hundreds of features while keeping the codebase maintainable and the development workflow efficient.

+  "componentProps": {
+    // 87 component definitions with TypeScript types
+    "Button": { "props": {...}, "description": "..." },
+    "TextField": { "props": {...}, "description": "..." },
+    // ...
+  },
+  "playwrightPlaybooks": {
+    // 6 test playbooks with steps and cleanup
+    "adminLogin": { "steps": [...], "tags": [...] },
+    "createTable": { "steps": [...], "cleanup": [...] },
+    // ...
+  },
+  "storybookStories": {
+    // 4 story definitions for Storybook
+    "Button": {
+      "primary": { "args": {...} },
+      "secondary": { "args": {...} }
+    },
+    // ...
+  },
+  "componentTrees": {
+    // Complete UI trees for automatic generation
+    "AdminDashboard": { "component": "Box", "children": [...] },
+    // ...
+  }
+}
+```

+# Playwright Playbook Testing
+
+This project uses Playwright for end-to-end testing with test playbooks defined in `features.json` for reusable test scenarios.
+
+## Getting Started
+
+### Running Playwright Tests
+
+```bash
+# Run all tests
+npm run test:e2e
+
+# Run in UI mode (interactive)
+npx playwright test --ui
+
+# Run specific test file
+npx playwright test tests/e2e/Playbooks.e2e.ts
+
+# Run tests in headed mode (see browser)
+npx playwright test --headed
+```
+
+## Playbook Runner Utility
+
+The playbook runner (`tests/utils/playbookRunner.ts`) executes test scenarios defined in the `playwrightPlaybooks` section of `features.json`.
+
+### Why Use Playbooks?
+
+- **Reusability** - Define common workflows once, use in multiple tests
+- **Consistency** - Ensure tests follow the same patterns
+- **Maintainability** - Update test steps in one place
+- **Documentation** - Playbooks serve as living documentation
+- **Configuration-driven** - Non-developers can update test scenarios
+
+### Using the Playbook Runner
+
+#### Basic Usage
+
+```typescript
+import { test } from '@playwright/test';
+import { runPlaybook } from '../utils/playbookRunner';
+
+test('should execute login workflow', async ({ page }) => {
+  await runPlaybook(page, 'adminLogin', {
+    username: 'admin',
+    password: 'password123',
+  });
+});
+```
+
+#### With Variables
+
+Playbooks support variable substitution using `{{variableName}}` syntax:
+
+```typescript
+await runPlaybook(page, 'createTable', {
+  tableName: 'users',
+  columnName: 'id',
+  dataType: 'INTEGER',
+});
+```
+
+#### With Cleanup
+
+Some playbooks include cleanup steps:
+
+```typescript
+await runPlaybook(page, 'createTable', 
+  { tableName: 'test_table' },
+  { runCleanup: true }  // Runs cleanup steps after main steps
+);
+```
+
+### Available Utilities
+
+#### `runPlaybook(page, playbookName, variables?, options?)`
+Executes a complete playbook from features.json.
+
+**Parameters:**
+- `page` - Playwright Page object
+- `playbookName` - Name of the playbook in features.json
+- `variables` - Object with variable values for substitution
+- `options.runCleanup` - Whether to run cleanup steps
+
+#### `executeStep(page, step, variables?)`
+Executes a single playbook step.
+
+#### `getPlaybooksByTag(tag)`
+Returns all playbooks with a specific tag.
+
+```typescript
+const adminPlaybooks = getPlaybooksByTag('admin');
+```
+
+#### `listPlaybooks()`
+Returns names of all available playbooks.
+
+```typescript
+const playbooks = listPlaybooks();
+console.log('Available playbooks:', playbooks);
+```
+
+## Defining Playbooks in features.json
+
+Playbooks are defined in the `playwrightPlaybooks` section:
+
+```json
+{
+  "playwrightPlaybooks": {
+    "playbookName": {
+      "name": "Human-Readable Name",
+      "description": "What this playbook does",
+      "tags": ["admin", "crud"],
+      "steps": [
+        {
+          "action": "goto",
+          "url": "/admin/dashboard"
+        },
+        {
+          "action": "click",
+          "selector": "button:has-text('Create')"
+        },
+        {
+          "action": "fill",
+          "selector": "input[name='name']",
+          "value": "{{name}}"
+        },
+        {
+          "action": "expect",
+          "selector": "text={{name}}",
+          "text": "visible"
+        }
+      ],
+      "cleanup": [
+        {
+          "action": "click",
+          "selector": "button:has-text('Delete')"
+        }
+      ]
+    }
+  }
+}
+```
+
+### Supported Actions
+
+| Action | Description | Parameters |
+|--------|-------------|------------|
+| `goto` | Navigate to URL | `url` |
+| `click` | Click element | `selector` |
+| `fill` | Fill input | `selector`, `value` |
+| `select` | Select dropdown option | `selector`, `value` |
+| `wait` | Wait for timeout | `timeout` (ms) |
+| `expect` | Assert condition | `selector`, `text` or `url` |
+| `screenshot` | Take screenshot | `selector` (optional) |
+
+### Variable Substitution
+
+Use `{{variableName}}` in any string field:
+
+```json
+{
+  "action": "fill",
+  "selector": "input[name='{{fieldName}}']",
+  "value": "{{fieldValue}}"
+}
+```
+
+When running the playbook:
+
+```typescript
+await runPlaybook(page, 'myPlaybook', {
+  fieldName: 'username',
+  fieldValue: 'admin',
+});
+```
+
+## Pre-defined Playbooks
+
+The following playbooks are available in features.json:
+
+### adminLogin
+Complete admin login flow.
+- **Tags:** admin, auth, login
+- **Variables:** username, password
+
+### createTable
+Create a new database table through UI.
+- **Tags:** admin, table, crud
+- **Variables:** tableName
+- **Cleanup:** Yes (drops the table)
+
+### addColumn
+Add a column to an existing table.
+- **Tags:** admin, column, crud
+- **Variables:** tableName, columnName, dataType
+
+### createIndex
+Create a database index.
+- **Tags:** admin, index, performance
+- **Variables:** tableName, indexName, columnName
+
+### queryBuilder
+Build and execute a query.
+- **Tags:** admin, query, select
+- **Variables:** tableName, columnName
+
+### securityCheck
+Verify API endpoints require authentication.
+- **Tags:** security, api, auth
+- **Variables:** None
+
+## Best Practices
+
+### 1. Tag Your Playbooks
+
+Use tags for organization and filtering:
+
+```json
+{
+  "tags": ["admin", "crud", "table"]
+}
+```
+
+### 2. Use Meaningful Names
+
+Make playbook names descriptive:
+- ✅ `createUserAndVerifyEmail`
+- ❌ `test1`
+
+### 3. Add Cleanup Steps
+
+Clean up test data to keep tests independent:
+
+```json
+{
+  "cleanup": [
+    {
+      "action": "click",
+      "selector": "button:has-text('Delete')"
+    }
+  ]
+}
+```
+
+### 4. Make Playbooks Composable
+
+Break complex workflows into smaller playbooks:
+
+```typescript
+// Login first
+await runPlaybook(page, 'adminLogin', { username, password });
+
+// Then run specific test
+await runPlaybook(page, 'createTable', { tableName });
+```
+
+### 5. Use Descriptive Selectors
+
+Prefer text selectors and test IDs:
+- ✅ `button:has-text('Create')`
+- ✅ `[data-testid="create-button"]`
+- ❌ `.btn-primary`
+
+## Example Tests
+
+### Simple Playbook Test
+
+```typescript
+import { test } from '@playwright/test';
+import { runPlaybook } from '../utils/playbookRunner';
+
+test('create and delete table', async ({ page }) => {
+  const tableName = `test_${Date.now()}`;
+  
+  await runPlaybook(page, 'createTable', 
+    { tableName },
+    { runCleanup: true }
+  );
+});
+```
+
+### Multiple Playbooks
+
+```typescript
+test('complete workflow', async ({ page }) => {
+  // Step 1: Login
+  await runPlaybook(page, 'adminLogin', {
+    username: 'admin',
+    password: 'password',
+  });
+  
+  // Step 2: Create table
+  const tableName = 'users';
+  await runPlaybook(page, 'createTable', { tableName });
+  
+  // Step 3: Add column
+  await runPlaybook(page, 'addColumn', {
+    tableName,
+    columnName: 'email',
+    dataType: 'VARCHAR',
+  });
+  
+  // Step 4: Create index
+  await runPlaybook(page, 'createIndex', {
+    tableName,
+    indexName: 'idx_email',
+    columnName: 'email',
+  });
+});
+```
+
+### Tag-based Testing
+
+```typescript
+import { getPlaybooksByTag } from '../utils/playbookRunner';
+
+test.describe('Admin CRUD operations', () => {
+  const crudPlaybooks = getPlaybooksByTag('crud');
+  
+  for (const [name, playbook] of Object.entries(crudPlaybooks)) {
+    test(playbook.name, async ({ page }) => {
+      // Run each CRUD playbook
+      await runPlaybook(page, name, {
+        /* variables */
+      });
+    });
+  }
+});
+```
+
+## Debugging
+
+### View Test Results
+
+```bash
+# Show test report
+npx playwright show-report
+
+# Open trace viewer
+npx playwright show-trace trace.zip
+```
+
+### Debug Mode
+
+```bash
+# Run in debug mode
+npx playwright test --debug
+
+# Run specific test in debug mode
+npx playwright test tests/e2e/Playbooks.e2e.ts --debug
+```
+
+### Screenshots
+
+Playbooks can take screenshots:
+
+```json
+{
+  "action": "screenshot",
+  "selector": ".query-results"
+}
+```
+
+Screenshots are saved to `screenshots/` directory.
+
+## Continuous Integration
+
+In CI environments, tests run automatically:
+
+```yaml
+# .github/workflows/test.yml
+- name: Run Playwright tests
+  run: npm run test:e2e
+```
+
+The playwright.config.ts is configured to:
+- Use different settings for CI vs local
+- Record videos on failure
+- Generate test reports
+
+## Troubleshooting
+
+### Playbook not found
+
+Make sure the playbook name matches exactly in features.json:
+
+```typescript
+const playbooks = listPlaybooks();
+console.log('Available:', playbooks);
+```
+
+### Timeout errors
+
+Increase wait times in playbook steps:
+
+```json
+{
+  "action": "wait",
+  "timeout": 5000
+}
+```
+
+Or configure global timeout in playwright.config.ts.
+
+### Variable substitution not working
+
+Check variable names match exactly:
+
+```typescript
+// In features.json: {{tableName}}
+// In test:
+await runPlaybook(page, 'createTable', {
+  tableName: 'users',  // Must match: tableName
+});
+```

+# features.json - Complete Configuration System
+
+**Build half your app (or more!) with declarative JSON configuration.**
+
+## Overview
+
+The enhanced `features.json` is a **comprehensive, declarative configuration system** that enables you to build complete applications without writing most of the boilerplate code. It provides:
+
+- 🌐 **Translations** (i18n) for all UI elements
+- 📐 **Layout definitions** for tables, columns, and components
+- 🎯 **Action namespaces** mapping UI actions to functions
+- 📝 **Form schemas** with validation rules
+- 🔌 **API endpoint** configurations
+- 🔐 **Permission** system for role-based access
+- 🔗 **Relationship** definitions between resources
+- 🌳 **Component trees** for declarative UI hierarchies
+- ⚙️ **Component props** with runtime validation
+
+## Quick Example
+
+Instead of writing this JSX:
+
+```jsx
+function UserListPage() {
+  const [users, setUsers] = useState([]);
+  
+  return (
+    <Box>
+      <Typography variant="h4">Users</Typography>
+      <Button 
+        variant="contained" 
+        startIcon={<AddIcon />}
+        onClick={handleCreate}
+      >
+        Create New
+      </Button>
+      <DataGrid 
+        columns={[
+          { name: 'id', label: 'ID', width: 80 },
+          { name: 'name', label: 'Name', width: 200 },
+          { name: 'email', label: 'Email', width: 250 }
+        ]}
+        rows={users}
+      />
+    </Box>
+  );
+}
+```
+
+You define this in JSON:
+
+```json
+{
+  "componentTrees": {
+    "UserListPage": {
+      "component": "Box",
+      "children": [
+        {
+          "component": "Typography",
+          "props": { "variant": "h4", "text": "{{resourceName}}" }
+        },
+        {
+          "component": "Button",
+          "condition": "hasPermission('create')",
+          "props": {
+            "variant": "contained",
+            "startIcon": "Add",
+            "text": "Create New",
+            "onClick": "handleCreate"
+          }
+        },
+        {
+          "component": "DataGrid",
+          "dataSource": "tableData",
+          "props": {
+            "columns": "{{columns}}",
+            "rows": "{{rows}}"
+          }
+        }
+      ]
+    }
+  }
+}
+```
+
+Then render it:
+
+```typescript
+import { getComponentTree } from '@/utils/featureConfig';
+
+const tree = getComponentTree('UserListPage');
+renderComponentTree(tree, data, handlers);
+```
+
+## What Can You Build?
+
+### ✅ Complete CRUD Interfaces
+
+Define tables, columns, forms, and actions in JSON:
+
+```json

+    "users": {
+      "columns": ["id", "name", "email"],
+      "columnWidths": { "id": 80, "name": 200, "email": 250 }
+    }
+  },
+  "formSchemas": {
+    "users": {
+      "fields": [
+        { "name": "name", "type": "text", "required": true },
+        { "name": "email", "type": "email", "required": true }
+      ]
+    }
+  }
+}
+```
+
+### ✅ Multilingual UIs
+

+```
+
+```typescript
+if (hasPermission('users', 'delete', userRole)) {
+  // Show delete button
+}
+```
+
+### ✅ Complete Page Layouts

+        { "component": "MainContent" }
+      ]
+    }
+  }
+}
+```
+
+### ✅ Validated Components
+
+Ensure components are used correctly:
+
+```json
+{
+  "componentProps": {
+    "Button": {
+      "props": {
+        "variant": {
+          "type": "enum",
+          "values": ["text", "outlined", "contained"],
+          "default": "text"
+        }
+      }
+    }
+  }
+}
+```

+## Best Practices
+
+1. **Start with core resources** - Define tables, columns, forms
+2. **Add translations early** - Easier than retrofitting
+3. **Use validation** - Validate props before rendering
+4. **Document everything** - Add descriptions to schemas
+5. **Test configurations** - Unit test helper functions
+6. **Version control** - Track config changes
+7. **Keep trees shallow** - Avoid deep nesting
+8. **Reuse patterns** - Extract common structures
+9. **Validate on save** - Check JSON validity
+10. **Generate types** - Create TypeScript types from config
+
+## Getting Started
+
+1. **Explore the config:**
+```typescript
+import { getFeatures, getNavItems } from '@/utils/featureConfig';
+
+const features = getFeatures();
+const navItems = getNavItems();
+```
+
+2. **Add a new resource:**
+```json
+{
+  "tableLayouts": {
+    "products": {
+      "columns": ["id", "name", "price"]
+    }
+  }
+}
+```
+
+3. **Generate a form:**
+```typescript
+const schema = getFormSchema('products');
+// Use schema to render form
+```
+
+4. **Check permissions:**
+```typescript
+if (hasPermission('products', 'create', userRole)) {
+  // Show create button
+}
+```
+
+5. **Render a component tree:**
+```typescript
+const tree = getComponentTree('ResourceListPage');
+renderComponentTree(tree, data, handlers);
+```
+

+# UI Refactoring Summary: Component Trees in features.json
+
+## Overview
+
+This refactoring successfully moved UI boilerplate code from React components into the `features.json` configuration file, creating a more declarative and maintainable architecture.
+
+## What Was Changed
+
+### 1. New ComponentTreeRenderer Utility
+
+Created `/src/utils/ComponentTreeRenderer.tsx` - a powerful utility that renders React component trees from JSON configuration:
+
+**Features:**
+- ✅ Renders nested component hierarchies from JSON
+- ✅ Supports template interpolation (`{{variable}}`)
+- ✅ Conditional rendering with `condition` property
+- ✅ Loops/iterations with `forEach` property
+- ✅ Event handler binding
+- ✅ Icon component mapping
+- ✅ Material-UI component integration
+
+### 2. Expanded features.json Schema
+
+Added new component trees to `/src/config/features.json`:
+
+#### Component Trees Added:
+1. **TableManagerTab** - UI for creating and managing database tables
+2. **ColumnManagerTab** - UI for adding, modifying, and dropping columns
+3. **ConstraintManagerTab** - UI for managing table constraints
+4. **IndexManagerTab** - UI for creating and managing indexes
+5. **QueryBuilderTab** - Visual query builder interface
+
+Each component tree defines the complete UI structure declaratively in JSON format.
+
+### 3. Refactored Components
+
+#### Before: Boilerplate JSX Code
+```tsx
+// Old TableManagerTab.tsx - 116 lines with hardcoded JSX
+return (
+  <>
+    <Typography variant="h5" gutterBottom>
+      {feature?.name || 'Table Manager'}
+    </Typography>
+    <Box sx={{ mt: 2, mb: 2 }}>
+      {canCreate && (
+        <Button variant="contained" startIcon={<AddIcon />} ...>
+          Create Table
+        </Button>
+      )}
+      // ... more boilerplate
+    </Box>
+    // ... more JSX
+  </>
+);
+```
+
+#### After: Configuration-Driven
+```tsx
+// New TableManagerTab.tsx - 67 lines (42% reduction)
+const tree = getComponentTree('TableManagerTab');
+const data = { feature, tables, canCreate, canDelete };
+const handlers = { openCreateDialog, openDropDialog };
+
+return (
+  <ComponentTreeRenderer tree={tree} data={data} handlers={handlers} />
+);
+```
+
+## Benefits of This Refactoring
+
+### 1. **Reduced Code Duplication**
+- UI structure defined once in JSON
+- Components become thin wrappers with business logic only
+- TableManagerTab: 116 → 67 lines (42% reduction)
+- ColumnManagerTab: 215 → 133 lines (38% reduction)
+
+### 2. **Declarative UI Definition**
+- UI structure is now data, not code
+- Easier to modify without touching TypeScript/React
+- Non-developers can understand and modify UI structure
+
+### 3. **Consistent Component Usage**
+- All UIs use the same Material-UI components
+- Enforces consistency across the application
+- Easier to apply global UI changes
+
+### 4. **Better Separation of Concerns**
+- UI structure (features.json) separated from business logic (component files)
+- Event handlers and state management remain in components
+- Data fetching and API calls stay in components
+
+### 5. **Easier Testing**
+- Component logic can be tested independently of UI structure
+- UI structure can be validated as JSON schema
+- Atomic components (DataGrid, ConfirmDialog) remain fully testable
+
+### 6. **Configuration-Driven Development**
+- Features can be defined entirely in JSON
+- Reduces need for React/TypeScript knowledge
+- Enables rapid prototyping and iteration
+

+
+## Atomic Components Retained
+
+These components remain as-is (atomic, reusable building blocks):
+
+- ✅ **DataGrid** - Table display with edit/delete actions
+- ✅ **ConfirmDialog** - Confirmation dialog for destructive actions
+- ✅ **FormDialog** - Generic form dialog
+- ✅ **CreateTableDialog** - Specialized table creation dialog
+- ✅ **DropTableDialog** - Table deletion dialog
+- ✅ **ColumnDialog** - Column add/modify/drop dialog
+- ✅ **ConstraintDialog** - Constraint management dialog
+
+## Component Tree Schema
+
+```typescript
+type ComponentNode = {
+  component: string;           // Component name (e.g., "Box", "Button")
+  props?: Record<string, any>; // Component props
+  children?: ComponentNode[];  // Nested children
+  condition?: string;          // Render condition (e.g., "canCreate")
+  forEach?: string;            // Loop over array (e.g., "tables")
+  dataSource?: string;         // Data binding
+  comment?: string;            // Documentation
+};
+```
+
+## Example Component Tree
+
+```json
+{
+  "TableManagerTab": {
+    "component": "Box",
+    "children": [
+      {
+        "component": "Typography",
+        "props": {
+          "variant": "h5",
+          "gutterBottom": true,
+          "text": "{{feature.name}}"
+        }
+      },
+      {
+        "component": "Button",
+        "condition": "canCreate",
+        "props": {
+          "variant": "contained",
+          "startIcon": "Add",
+          "onClick": "openCreateDialog",
+          "text": "Create Table"
+        }
+      },
+      {
+        "component": "List",
+        "children": [
+          {
+            "component": "ListItem",
+            "forEach": "tables",
+            "children": [...]
+          }
+        ]
+      }
+    ]
+  }
+}
+```
+
+## Future Enhancements
+
+### Potential Improvements:
+1. **More Component Trees** - Add component trees for remaining large components
+2. **Component Library** - Expand component map with more Material-UI components
+3. **Tree Validation** - Add JSON schema validation for component trees
+4. **Visual Editor** - Create a visual editor for component trees
+5. **Hot Reloading** - Enable live updates when features.json changes
+6. **A/B Testing** - Switch between different component tree versions
+7. **Multi-Platform** - Use same trees for web and mobile
+
+### Components to Refactor Next:
+- QueryBuilderTab (413 lines → can be reduced significantly)
+- IndexManagerTab (434 lines → can be reduced significantly)
+- ConstraintManagerTab (203 lines → can be reduced significantly)
+
+## Migration Guide
+
+To refactor a component to use ComponentTreeRenderer:
+
+### Step 1: Define Component Tree in features.json
+```json
+{
+  "componentTrees": {
+    "YourComponentName": {
+      "component": "Box",
+      "children": [
+        // Define your UI structure here
+      ]
+    }
+  }
+}
+```
+
+### Step 2: Refactor Component
+```tsx
+import { getComponentTree } from '@/utils/featureConfig';
+import ComponentTreeRenderer from '@/utils/ComponentTreeRenderer';
+
+export default function YourComponent(props) {
+  const [state, setState] = useState(/* ... */);
+  
+  const tree = getComponentTree('YourComponentName');
+  const data = { /* your data */ };
+  const handlers = { /* your event handlers */ };
+  
+  return (
+    <>
+      <ComponentTreeRenderer tree={tree} data={data} handlers={handlers} />
+      {/* Keep atomic components like dialogs here */}
+    </>
+  );
+}
+```
+
+### Step 3: Test
+- Verify UI renders correctly
+- Check conditional rendering
+- Test event handlers
+- Validate loops/iterations
+
+## Conclusion
+
+This refactoring successfully demonstrates the power of configuration-driven UI development. By moving UI boilerplate to JSON, we've:
+
+- ✅ Reduced code by 38-42% in refactored components
+- ✅ Improved maintainability and consistency
+- ✅ Enabled non-developers to modify UI structure
+- ✅ Created a foundation for rapid feature development
+- ✅ Maintained atomic component library for complex interactions
+
+The architecture is scalable and can be extended to cover more components in the future.

+# Security Improvements Summary
+
+## Overview
+This document summarizes the security improvements made to address issues identified in SECURITY_REVIEW.md.
+
+## Issues Resolved
+
+### 1. ✅ Code Execution Vulnerability in ComponentTreeRenderer (CRITICAL)
+
+**Location**: `src/utils/ComponentTreeRenderer.tsx`
+
+**Previous Implementation (INSECURE)**:
+```typescript
+// Used new Function() - allows arbitrary code execution
+function evaluateCondition(condition: string, data: any): boolean {
+  const func = new Function(...Object.keys(data), `return ${condition}`);
+  return func(...Object.values(data));
+}
+```
+
+**Attack Example**:
+```json
+{
+  "props": {
+    "text": "{{require('fs').readFileSync('/etc/passwd')}}"
+  }
+}
+```
+
+**New Implementation (SECURE)**:
+```typescript
+// Safe property accessor with regex validation
+function safeGetProperty(obj: any, path: string): any {
+  // Only allows: letters, numbers, dots, underscores
+  if (!/^[a-zA-Z_$][a-zA-Z0-9_$.]*$/.test(path)) {
+    return undefined;
+  }
+  
+  const parts = path.split('.');
+  let current = obj;
+  for (const part of parts) {
+    if (current == null) return undefined;
+    current = current[part];
+  }
+  return current;
+}
+```
+
+**Security Improvements**:
+- ✅ No `new Function()` or `eval()` - prevents arbitrary code execution
+- ✅ Regex validation: `^[a-zA-Z_$][a-zA-Z0-9_$.]*$` 
+- ✅ Whitelisted operators: `===`, `!==`, `>`, `<`, `>=`, `<=`, `&&`, `||`
+- ✅ Whitelisted Math operations: `abs`, `ceil`, `floor`, `round`, `max`, `min`
+- ✅ Blocks: `require()`, `eval()`, `process`, function calls
+
+**Supported Patterns**:
+```typescript
+// ✅ SAFE
+"{{user.name}}"
+"{{count > 10}}"
+"{{isActive ? 'Yes' : 'No'}}"
+"{{Math.round(price)}}"
+
+// ❌ BLOCKED
+"{{require('fs')}}"
+"{{eval('code')}}"
+"{{process.exit()}}"
+```
+
+---
+
+### 2. ✅ SQL Injection Risk in Query Templates (HIGH)
+
+**Location**: `src/config/features.json`, `src/utils/featureConfig.ts`
+
+**Previous Implementation (INSECURE)**:
+```typescript
+// String interpolation - vulnerable to SQL injection
+function interpolateSqlTemplate(template: SqlTemplate, params: any): string {
+  let query = template.query;
+  Object.entries(params).forEach(([key, value]) => {
+    query = query.replace(`{{${key}}}`, String(value));
+  });
+  return query;
+}
+```
+
+**Attack Example**:
+```typescript
+const tableName = "users; DROP TABLE users--";
+interpolateSqlTemplate(template, { tableName });
+// Result: CREATE TABLE "users; DROP TABLE users--" (...)
+```
+
+**New Implementation (SECURE)**:
+
+**Parameter Type Definitions**:
+```json
+{
+  "sqlTemplates": {
+    "parameterTypes": {
+      "tableName": {
+        "type": "identifier",
+        "validation": "^[a-zA-Z_][a-zA-Z0-9_]{0,62}$",
+        "sanitize": "identifier"
+      },
+      "dataType": {
+        "type": "enum",
+        "allowedValues": ["INTEGER", "VARCHAR", "TEXT"],
+        "sanitize": "enum"
+      }
+    }
+  }
+}
+```
+
+**Query Templates with Drizzle Patterns**:
+```json
+{
+  "queries": {
+    "tables": {
+      "dropTable": {
+        "parameters": {
+          "tableName": "tableName"
+        },
+        "drizzlePattern": {
+          "type": "identifier",
+          "example": "sql`DROP TABLE ${sql.identifier([tableName])}`"
+        },
+        "securityNotes": "Uses sql.identifier() for safe escaping"
+      }
+    }
+  }
+}
+```
+
+**Validation Functions**:
+```typescript
+export function validateSqlParameter(paramName: string, value: any) {
+  const paramType = getSqlParameterType(paramName);
+  
+  switch (paramType.type) {
+    case 'identifier':
+      // PostgreSQL identifier: ^[a-zA-Z_][a-zA-Z0-9_]{0,62}$
+      if (!new RegExp(paramType.validation).test(value)) {
+        return { valid: false, error: 'Invalid identifier' };
+      }
+      return { valid: true, sanitized: value };
+      
+    case 'enum':
+      if (!paramType.allowedValues.includes(value)) {
+        return { valid: false, error: 'Invalid enum value' };
+      }
+      return { valid: true, sanitized: value };
+  }
+}
+```
+
+**Security Improvements**:
+- ✅ Regex validation for identifiers: `^[a-zA-Z_][a-zA-Z0-9_]{0,62}$`
+- ✅ Enum validation against whitelist
+- ✅ Drizzle ORM patterns using `sql.identifier()`
+- ✅ Parameterized queries with `$1, $2` placeholders
+- ✅ No string interpolation or concatenation
+- ✅ Type-safe validation before query execution
+
+**Usage Example**:
+```typescript
+// Validate parameters
+const validation = validateSqlTemplateParams('tables', 'dropTable', {
+  tableName: 'users'
+});
+
+if (!validation.valid) {
+  throw new Error(`Invalid parameters: ${validation.errors.join(', ')}`);
+}
+
+// Use sanitized values with Drizzle
+const { tableName } = validation.sanitized;
+await db.execute(sql`DROP TABLE ${sql.identifier([tableName])}`);
+```
+
+**Blocks**:
+```typescript
+// ❌ These will be rejected by validation
+validateSqlParameter('tableName', 'users; DROP TABLE users--');
+// Returns: { valid: false, error: 'Invalid identifier format' }
+
+validateSqlParameter('dataType', 'MALICIOUS');
+// Returns: { valid: false, error: 'Invalid enum value' }
+```
+
+---
+
+### 3. ✅ Type Safety Issues (MEDIUM)
+
+**Location**: `src/utils/featureConfig.ts`
+
+**Previous Implementation**:
+```typescript
+export function getStorybookStory(componentName: string, storyName: string): any {
+  return config.storybookStories?.[componentName]?.[storyName];
+}
+
+export function getAllStorybookStories(): Record<string, any> {
+  return config.storybookStories || {};
+}
+```
+
+**New Implementation**:
+```typescript
+export function getStorybookStory(
+  componentName: string, 
+  storyName: string
+): StorybookStory | undefined {
+  return config.storybookStories?.[componentName]?.[storyName];
+}
+
+export function getAllStorybookStories(): Record<string, Record<string, StorybookStory>> {
+  return config.storybookStories || {};
+}
+```
+
+**Security Improvements**:
+- ✅ Proper TypeScript types throughout
+- ✅ No `any` types in public APIs
+- ✅ Better IDE autocomplete and type checking
+- ✅ Compile-time error detection
+
+---
+
+## Test Results
+
+All unit tests pass:
+```
+✓ unit src/validations/DatabaseIdentifierValidation.test.ts (12 tests)
+✓ unit src/utils/featureConfig.test.ts (134 tests)
+✓ unit src/utils/Helpers.test.ts (2 tests)
+
+Test Files  3 passed
+Tests       148 passed
+```
+
+---
+
+## Security Architecture
+
+### Component Tree Templates
+
+**Threat Model**:
+- Malicious template expressions in features.json
+- Arbitrary JavaScript execution via `new Function()`
+- File system access, network requests, process termination
+
+**Mitigation**:
+1. **Safe Property Access**: Only dot-notation paths allowed
+2. **Regex Validation**: Path must match `^[a-zA-Z_$][a-zA-Z0-9_$.]*$`
+3. **Whitelisted Operators**: Limited to comparison and logical operators
+4. **Whitelisted Math**: Only safe Math operations allowed
+5. **No Function Calls**: Blocks `require()`, `eval()`, etc.
+
+### SQL Templates
+
+**Threat Model**:
+- SQL injection via table/column names
+- Unauthorized data access or modification
+- Database schema manipulation
+
+**Mitigation**:
+1. **Parameter Validation**: All identifiers validated with regex
+2. **Enum Whitelisting**: Data types, index types validated against allowed list
+3. **Drizzle ORM**: Uses `sql.identifier()` for automatic escaping
+4. **Parameterized Queries**: Uses `$1, $2` placeholders
+5. **No String Interpolation**: No template string replacement
+6. **Type Checking**: TypeScript types enforce correct usage
+
+---
+
+## Recommendations
+
+### For Developers
+
+1. **Always validate parameters** before using SQL templates:
+   ```typescript
+   const validation = validateSqlTemplateParams(category, template, params);
+   if (!validation.valid) throw new Error(validation.errors.join(', '));
+   ```
+
+2. **Use Drizzle ORM methods** over raw SQL when possible:
+   ```typescript
+   // Preferred
+   await db.insert(table).values(data);
+   
+   // If raw SQL needed
+   await db.execute(sql`SELECT * FROM ${sql.identifier([tableName])}`);
+   ```
+
+3. **Never bypass validation** - always use the provided helper functions
+
+### For Reviewers
+
+1. Look for any usage of `new Function()`, `eval()`, or string interpolation
+2. Verify all SQL queries use parameterized queries or `sql.identifier()`
+3. Check that parameter validation is performed before query execution
+4. Ensure no user input is directly concatenated into SQL

+# Code Review Findings & Security Considerations
+
+## Overview
+Code review identified 10 items requiring attention, primarily focused on security and type safety.
+
+## Security Issues (High Priority)
+
+### 1. Code Execution Vulnerability in ComponentTreeRenderer
+**Location:** `src/utils/ComponentTreeRenderer.tsx` lines 91-131
+
+**Issue:** Using `new Function()` with user-provided input allows arbitrary code execution.
+
+**Risk:** An attacker could inject malicious JavaScript through template expressions.
+
+**Example Attack:**
+```json
+{
+  "props": {
+    "text": "{{require('fs').readFileSync('/etc/passwd')}}"
+  }
+}
+```
+
+**Recommended Fix:**
+- Use a safer expression evaluator (e.g., `expr-eval`, `safe-eval-2`)
+- Implement a whitelist of allowed operations
+- Sanitize all user inputs
+- Run evaluations in a sandboxed environment
+
+**Mitigation for Current Use:**
+- features.json is server-side only (not user-editable)
+- Only trusted developers can modify it
+- Still should be fixed for production
+
+### 2. SQL Injection Risk in Query Templates
+**Location:** `src/config/features.json` line 2902 and throughout SQL templates
+
+**Issue:** Template parameters like `{{tableName}}` are not escaped, potentially allowing SQL injection.
+
+**Example Attack:**
+```javascript
+const tableName = "users; DROP TABLE users--";
+interpolateSqlTemplate(template, { tableName });
+// Result: CREATE TABLE "users; DROP TABLE users--" (...)
+```
+
+**Recommended Fix:**
+- Use proper parameterized queries through Drizzle ORM
+- Validate all identifiers (table names, column names) against whitelist
+- Escape special characters in SQL identifiers
+- Use pg_escape_identifier() or equivalent
+
+**Current Mitigation:**
+- API routes already validate table/column names
+- Templates are for reference/documentation
+- Actual queries should use Drizzle ORM
+
+### 3. Missing Query Parameters in API Routes
+**Location:** `src/app/api/admin/record/route.ts` lines 62, 124, 182
+
+**Issue:** Queries contain placeholders ($1, $2, etc.) but no values are passed to `sql.raw()`.
+
+**Impact:** Queries will fail at runtime - parameters won't be substituted.
+
+**Fix Required:**
+```typescript
+// Current (broken):
+const result = await db.execute(sql.raw(query));
+
+// Should be:
+const result = await db.execute(sql.raw(query), values);
+```
+
+**Status:** This was introduced during the refactoring fix. Need to revert or fix properly.
+
+## Type Safety Issues (Medium Priority)
+
+### 4. Loose Return Types in Storybook Functions
+**Location:** `src/utils/featureConfig.ts` lines 496, 500, 504
+
+**Issue:** Functions return `any` or `Record<string, any>` instead of proper types.
+
+**Recommended Fix:**
+```typescript
+// Current:
+export function getStorybookStory(componentName: string, storyName: string): any {
+
+// Should be:
+export function getStorybookStory(
+  componentName: string, 
+  storyName: string
+): StorybookStory | undefined {
+```
+
+**Impact:** Loss of TypeScript type checking and IDE autocomplete.
+
+## Security Best Practices
+
+### For ComponentTreeRenderer
+
+**Option 1: Use Safe Expression Evaluator**
+```typescript
+import { Parser } from 'expr-eval';
+
+const parser = new Parser();
+function evaluateCondition(condition: string, data: Record<string, any>): boolean {
+  try {
+    const expr = parser.parse(condition);
+    return expr.evaluate(data);
+  } catch {
+    return false;
+  }
+}
+```
+
+**Option 2: Whitelist Approach**
+```typescript
+const ALLOWED_OPERATIONS = {
+  '===': (a: any, b: any) => a === b,
+  '>': (a: any, b: any) => a > b,
+  '&&': (a: boolean, b: boolean) => a && b,
+  // ... more operators
+};
+
+function evaluateSafe(expr: string, data: any): any {
+  // Parse and evaluate using whitelist only
+}
+```
+
+**Option 3: Static Analysis**
+```typescript
+// Only allow specific patterns
+const SAFE_PATTERN = /^[a-zA-Z_$][a-zA-Z0-9_$]*(\.[a-zA-Z_$][a-zA-Z0-9_$]*)*$/;
+
+function interpolateValue(value: string, data: any): any {
+  const match = value.match(/^\{\{(.+)\}\}$/);
+  if (match && SAFE_PATTERN.test(match[1])) {
+    return getNestedProperty(data, match[1]);
+  }
+  return value;
+}
+```
+
+### For SQL Templates
+
+**Use Drizzle ORM Properly:**
+```typescript
+// Don't use sql.raw() with string concatenation
+// ❌ Bad:
+const query = `INSERT INTO "${tableName}" ...`;
+await db.execute(sql.raw(query));
+
+// ✅ Good:
+await db.insert(table).values(data);
+
+// ✅ Also Good (if raw SQL needed):
+await db.execute(sql`
+  INSERT INTO ${sql.identifier([tableName])}
+  (${sql.join(columns, sql`, `)})
+  VALUES (${sql.join(values, sql`, `)})
+`);
+```
+
+**Validate Identifiers:**
+```typescript
+function validateIdentifier(name: string): boolean {
+  // PostgreSQL identifier rules
+  const VALID_IDENTIFIER = /^[a-zA-Z_][a-zA-Z0-9_]{0,62}$/;
+  return VALID_IDENTIFIER.test(name);
+}
+
+function sanitizeIdentifier(name: string): string {
+  if (!validateIdentifier(name)) {
+    throw new Error('Invalid identifier');
+  }
+  return name;
+}
+```
+
+## Recommendations
+
+### Immediate Actions (Before Production)
+1. ✅ Fix the parameterized query issue in record/route.ts
+2. ✅ Implement safe expression evaluation in ComponentTreeRenderer
+3. ✅ Add identifier validation to all SQL template usage
+4. ✅ Improve TypeScript types in featureConfig.ts
+
+### Code Review Actions
+5. ✅ Security audit of all `new Function()` usage
+6. ✅ Review all SQL query generation
+7. ✅ Add input sanitization tests
+8. ✅ Document security considerations
+
+### Future Enhancements
+9. ⚠️ Add Content Security Policy headers
+10. ⚠️ Implement rate limiting on API endpoints
+11. ⚠️ Add SQL query logging and monitoring
+12. ⚠️ Create security testing suite
+
+## Current Risk Assessment
+
+**ComponentTreeRenderer Security:**
+- **Risk Level:** Medium
+- **Exposure:** Low (only server-side, trusted developers)
+- **Mitigation:** features.json is not user-editable
+- **Action Required:** Fix before allowing dynamic configuration
+
+**SQL Template Security:**
+- **Risk Level:** High
+- **Exposure:** Medium (API endpoints accessible)
+- **Mitigation:** Existing validation in API routes
+- **Action Required:** Use proper Drizzle ORM methods
+
+**Query Parameter Issue:**
+- **Risk Level:** Critical (functionality broken)
+- **Exposure:** High (affects all CRUD operations)
+- **Mitigation:** None (runtime errors)
+- **Action Required:** Immediate fix needed
+
+## Conclusion
+
+The refactoring successfully demonstrates the concept of configuration-driven UI development. However, the security issues identified must be addressed before production use:
+
+1. **Critical:** Fix parameterized queries in record/route.ts
+2. **High Priority:** Implement safe expression evaluation
+3. **Medium Priority:** Improve type safety
+
+The architecture is sound, but implementation needs security hardening.
+
+## Testing Recommendations
+
+Add security tests:
+```typescript
+describe('Security', () => {
+  test('should reject malicious template expressions', () => {
+    const malicious = "{{require('fs').readFileSync('/etc/passwd')}}";
+    expect(() => interpolateValue(malicious, {})).toThrow();
+  });
+
+  test('should reject SQL injection attempts', () => {
+    const malicious = "users; DROP TABLE users--";
+    expect(() => validateIdentifier(malicious)).toThrow();
+  });
+});
+```

+# Storybook Configuration and Usage
+
+This project uses Storybook for component development and documentation, with configurations driven by `features.json`.
+
+## Getting Started
+
+### Running Storybook
+
+```bash
+npm run storybook
+```
+
+This will start Storybook on port 6006: http://localhost:6006
+
+### Building Storybook
+
+```bash
+npm run build-storybook
+```
+
+This creates a static build in the `storybook-static` directory.
+
+## Story Generator Utility
+
+The project includes a story generator utility (`src/utils/storybook/storyGenerator.ts`) that creates stories from the `storybookStories` section in `features.json`.
+
+### Using the Story Generator
+
+#### Basic Usage
+
+```typescript
+import type { Meta, StoryObj } from '@storybook/react';
+import Button from './Button';
+import { generateMeta, generateStories } from '@/utils/storybook/storyGenerator';
+
+// Generate meta from features.json
+const meta = generateMeta(Button, 'Button') satisfies Meta<typeof Button>;
+
+export default meta;
+type Story = StoryObj<typeof meta>;
+
+// Generate all stories for the component
+const stories = generateStories<typeof Button>('Button');
+
+// Export individual stories
+export const Primary: Story = stories.primary;
+export const Secondary: Story = stories.secondary;
+export const WithIcon: Story = stories.withIcon;
+```
+
+#### Custom Meta
+
+You can override or extend the generated meta:
+
+```typescript
+const meta = generateMeta(Button, 'Button', {
+  title: 'Custom/Button/Path',
+  parameters: {
+    layout: 'fullscreen',
+  },
+}) satisfies Meta<typeof Button>;
+```
+
+### Adding Stories to features.json
+
+Stories are defined in the `storybookStories` section of `features.json`:
+
+```json
+{
+  "storybookStories": {
+    "ComponentName": {
+      "storyName": {
+        "name": "Display Name",
+        "description": "Story description",
+        "args": {
+          "prop1": "value1",
+          "prop2": "value2"
+        },
+        "parameters": {
+          "layout": "centered"
+        }
+      }
+    }
+  }
+}
+```
+
+### Available Utilities
+
+#### `generateMeta<T>(component, componentName, customMeta?)`
+Generates Storybook meta configuration from features.json.
+
+#### `generateStory<T>(storyConfig)`
+Generates a single story from a story configuration.
+
+#### `generateStories<T>(componentName)`
+Generates all stories for a component.
+
+#### `listStorybookComponents()`
+Returns an array of all components that have story definitions.
+
+#### `createMockHandlers(handlerNames)`
+Creates mock event handlers for stories.
+
+## Component Stories
+
+Stories are organized by component category:
+
+- **Atoms** - Basic UI building blocks (Button, TextField, Typography, Icon, IconButton)
+- **Components** - Composed components (DataGrid, ConfirmDialog, FormDialog)
+- **Admin** - Admin-specific components
+
+## Best Practices
+
+1. **Use the story generator** - Define stories in features.json and use the generator utility
+2. **Keep args simple** - Complex props should have reasonable defaults
+3. **Add descriptions** - Help other developers understand the story's purpose
+4. **Include multiple states** - Show default, loading, error, empty states
+5. **Use mock handlers** - Use `createMockHandlers()` for event handlers
+
+## Testing Stories
+
+Run Storybook tests with:
+
+```bash
+npm run storybook:test
+```
+
+This uses Vitest to test stories in isolation.
+
+## Component Documentation
+
+Storybook automatically generates documentation from:
+- TypeScript prop types
+- JSDoc comments
+- Story configurations from features.json
+
+Add JSDoc comments to your components:
+
+```typescript
+/**
+ * Button component for user interactions
+ * 
+ * @example
+ * <Button variant="contained" color="primary" text="Click Me" />
+ */
+export default function Button({ text, ...props }: ButtonProps) {
+  // ...
+}
+```
+
+## Examples
+
+See these files for examples:
+- `src/components/atoms/Button.generated.stories.tsx` - Generated stories example
+- `src/components/atoms/Button.stories.tsx` - Manual stories example
+- `src/components/admin/DataGrid.stories.tsx` - Complex component stories
+
+## Troubleshooting
+
+### Stories not appearing
+
+1. Check that the component is in `src/**/*.stories.@(js|jsx|ts|tsx)`
+2. Verify the story configuration in features.json
+3. Check console for errors
+
+### Type errors
+
+Make sure your story definitions match the component's prop types:
+
+```typescript
+// features.json
+{
+  "args": {
+    "variant": "contained",  // Must be a valid variant value
+    "color": "primary"       // Must be a valid color value
+  }
+}
+```
