+# Ant Design Import Rules for Worklenz
+
+## 🚨 CRITICAL: Always Use Centralized Imports
+
+**NEVER import Ant Design components directly from 'antd' or '@ant-design/icons'**
+
+### ✅ Correct Import Pattern
+```typescript
+import { Button, Input, Select, EditOutlined, PlusOutlined } from '@antd-imports';
+// or
+import { Button, Input, Select, EditOutlined, PlusOutlined } from '@/shared/antd-imports';
+```
+
+### ❌ Forbidden Import Patterns
+```typescript
+// NEVER do this:
+import { Button, Input, Select } from 'antd';
+import { EditOutlined, PlusOutlined } from '@ant-design/icons';
+```
+
+## Why This Rule Exists
+
+### Benefits of Centralized Imports:
+- **Better Tree-Shaking**: Optimized bundle size through centralized management
+- **Consistent React Context**: Proper context sharing across components
+- **Type Safety**: Centralized TypeScript definitions
+- **Maintainability**: Single source of truth for all Ant Design imports
+- **Performance**: Reduced bundle size and improved loading times
+
+## What's Available in `@antd-imports`
+
+### Core Components
+- **Layout**: Layout, Row, Col, Flex, Divider, Space
+- **Navigation**: Menu, Tabs, Breadcrumb, Pagination
+- **Data Entry**: Input, Select, DatePicker, TimePicker, Form, Checkbox, InputNumber
+- **Data Display**: Table, List, Card, Tag, Avatar, Badge, Progress, Statistic
+- **Feedback**: Modal, Drawer, Alert, Message, Notification, Spin, Skeleton, Result
+- **Other**: Button, Typography, Tooltip, Popconfirm, Dropdown, ConfigProvider
+
+### Icons
+Common icons including: EditOutlined, DeleteOutlined, PlusOutlined, MoreOutlined, CheckOutlined, CloseOutlined, CalendarOutlined, UserOutlined, TeamOutlined, and many more.
+
+### Utilities
+- **appMessage**: Centralized message utility
+- **appNotification**: Centralized notification utility
+- **antdConfig**: Default Ant Design configuration
+- **taskManagementAntdConfig**: Task-specific configuration
+
+## Implementation Guidelines
+
+### When Creating New Components:
+1. **Always** import from `@/shared/antd-imports`
+2. Use `appMessage` and `appNotification` for user feedback
+3. Apply `antdConfig` for consistent styling
+4. Use `taskManagementAntdConfig` for task-related components
+
+### When Refactoring Existing Code:
+1. Replace direct 'antd' imports with `@/shared/antd-imports`
+2. Replace direct '@ant-design/icons' imports with `@/shared/antd-imports`
+3. Update any custom message/notification calls to use the utilities
+
+### File Location
+The centralized import file is located at: `worklenz-frontend/src/shared/antd-imports.ts`
+
+## Examples
+
+### Component Creation
+```typescript
+import React from 'react';
+import { Button, Input, Modal, EditOutlined, appMessage } from '@antd-imports';
+
+const MyComponent = () => {
+  const handleClick = () => {
+    appMessage.success('Operation completed!');
+  };
+
+  return (
+    <Button icon={<EditOutlined />} onClick={handleClick}>
+      Edit Item
+    </Button>
+  );
+};
+```
+
+### Form Implementation
+```typescript
+import { Form, Input, Select, Button, DatePicker } from '@antd-imports';
+
+const MyForm = () => {
+  return (
+    <Form layout="vertical">
+      <Form.Item label="Name" name="name">
+        <Input />
+      </Form.Item>
+      <Form.Item label="Type" name="type">
+        <Select options={options} />
+      </Form.Item>
+      <Form.Item label="Date" name="date">
+        <DatePicker />
+      </Form.Item>
+    </Form>
+  );
+};
+```
+
+## Enforcement
+
+This rule is **MANDATORY** and applies to:
+- All new component development
+- All code refactoring
+- All bug fixes
+- All feature implementations
+
+**Violations will result in code review rejection.**

+# Node-pg-migrate Migrations
+
+This directory contains database migrations managed by node-pg-migrate.
+
+## Migration Commands
+
+- `npm run migrate:create -- migration-name` - Create a new migration file
+- `npm run migrate:up` - Run all pending migrations
+- `npm run migrate:down` - Rollback the last migration
+- `npm run migrate:redo` - Rollback and re-run the last migration
+
+## Migration File Format
+
+Migrations are JavaScript files with timestamp prefixes (e.g., `20250115000000_performance-indexes.js`).
+
+Each migration file exports two functions:
+- `exports.up` - Contains the forward migration logic
+- `exports.down` - Contains the rollback logic
+
+## Best Practices
+
+1. **Always use IF EXISTS/IF NOT EXISTS checks** to make migrations idempotent
+2. **Test migrations locally** before deploying to production
+3. **Include rollback logic** in the `down` function for all changes
+4. **Use descriptive names** for migration files
+5. **Keep migrations focused** - one logical change per migration
+
+## Example Migration
+
+```javascript
+exports.up = pgm => {
+  // Create table with IF NOT EXISTS
+  pgm.createTable('users', {
+    id: 'id',
+    name: { type: 'varchar(100)', notNull: true },
+    created_at: {
+      type: 'timestamp',
+      notNull: true,
+      default: pgm.func('current_timestamp')
+    }
+  }, { ifNotExists: true });
+
+  // Add index with IF NOT EXISTS
+  pgm.createIndex('users', 'name', {
+    name: 'idx_users_name',
+    ifNotExists: true
+  });
+};
+
+exports.down = pgm => {
+  // Drop in reverse order
+  pgm.dropIndex('users', 'name', { 
+    name: 'idx_users_name', 
+    ifExists: true 
+  });
+  
+  pgm.dropTable('users', { ifExists: true });
+};
+```
+
+## Migration History
+
+The `pgmigrations` table tracks which migrations have been run. Do not modify this table manually.
+
+## Converting from SQL Migrations
+
+When converting SQL migrations to node-pg-migrate format:
+
+1. Wrap SQL statements in `pgm.sql()` calls
+2. Use node-pg-migrate helper methods where possible (createTable, addColumns, etc.)
+3. Always include `IF EXISTS/IF NOT EXISTS` checks
+4. Ensure proper rollback logic in the `down` function
