Frontend: ANTD Components

All new components must use Ant Design (ANTD) with theme tokens. Never use Radix UI, TailwindCSS, or hardcoded values for new development.

Theme Tokens (Required)

Always use ANTD theme tokens instead of hardcoded values:

typescript

import { theme } from 'antd';

function MyComponent() {
  const { token } = theme.useToken();

  return (
    <div style={{
      padding: token.paddingXL,
      color: token.colorPrimary,
      fontSize: token.fontSizeLG,
      borderRadius: token.borderRadiusLG,
    }}>
      Content
    </div>
  );
}

Common Token Categories:

•Colors: token.colorPrimary, token.colorError, token.colorSuccess, token.colorBorder
•Spacing: token.paddingSM, token.marginMD, token.paddingLG, token.marginXL
•Typography: token.fontSize, token.fontSizeLG, token.fontSizeHeading1
•Borders: token.borderRadius, token.borderRadiusLG

Typography Components

Use ANTD Typography components for text content:

typescript

import { Typography, theme } from 'antd';

const { Title, Paragraph, Text } = Typography;

function MyComponent() {
  const { token } = theme.useToken();

  return (
    <>
      <Title level={1}>Page Title</Title>
      <Paragraph type="secondary">Description text</Paragraph>
      <Text strong>Bold text</Text>
    </>
  );
}

App.useApp Pattern (Message/Notification/Modal)

Always use App.useApp() hook for feedback components:

typescript

import { App } from 'antd';

function MyComponent() {
  const { message, notification, modal } = App.useApp();

  const handleSuccess = () => {
    message.success('Operation successful!');
  };

  const handleNotify = () => {
    notification.info({
      message: 'Update Available',
      description: 'A new version is ready.',
    });
  };

  return <button onClick={handleSuccess}>Save</button>;
}

Note: Your app must be wrapped with <App> in the provider. See src/providers/antd/Provider_ANTD.tsx.

Modal Confirmations (Async Pattern)

Always use async onOk with mutateAsync for delete confirmations and critical actions:

typescript

import { App } from 'antd';
import { useM_Files_Delete } from "@/hooks/Files/useM_Files_Delete";

function MyComponent() {
    const { modal } = App.useApp();
    const mFiles_Delete = useM_Files_Delete();

    const handleDelete = (fileId: string, fileName: string) => {
        modal.confirm({
            title: "Delete File",
            content: `Are you sure you want to delete "${fileName}"?`,
            okText: "Delete",
            okType: "danger",
            onOk: async () => {
                await mFiles_Delete.mutation.mutateAsync({ fileId });
            },
        });
    };

    return <button onClick={() => handleDelete('file_1', 'document.pdf')}>Delete</button>;
}

Why async onOk matters:

•Modal stays open until mutation completes
•Loading spinner shows automatically on OK button
•Errors prevent modal from closing
•Success closes modal automatically

Icon Usage

Primary: Use @ant-design/icons for all icons:

typescript

import { PlusOutlined, EditOutlined, ProjectOutlined } from '@ant-design/icons';

function MyComponent() {
  const { token } = theme.useToken();

  return (
    <>
      <Button icon={<PlusOutlined />}>Create</Button>
      <ProjectOutlined style={{ fontSize: 18, color: token.colorPrimary }} />
    </>
  );
}

Alternative: Use lucide-react only when ANTD doesn't have a suitable icon. Never mix both in the same component.

Form Handling

Use ANTD Form components with validation rules:

typescript

import { Form, Input, Button } from 'antd';

function MyComponent() {
  const [form] = Form.useForm();

  const handleSubmit = () => {
    form.validateFields().then((values) => {
      // Handle submission
    });
  };

  return (
    <Form form={form} layout="vertical">
      <Form.Item
        label="Name"
        name="name"
        rules={[
          { required: true, message: 'Please enter a name' },
          { min: 1, max: 255, message: 'Name must be 1-255 characters' },
        ]}
      >
        <Input placeholder="Enter name..." />
      </Form.Item>

      <Button type="primary" onClick={handleSubmit}>
        Submit
      </Button>
    </Form>
  );
}

CSS/Styling Rules

•No separate CSS/SCSS files for new components
•Use: ANTD components + inline styles with theme tokens
•Legacy: Existing TailwindCSS components remain as-is (no refactoring required)

Deprecated Props (Avoid)

Some ANTD props are deprecated and cause console warnings. Always use the new replacement props.

Common Deprecated Props:

•❌ Card: bodyStyle → ✅ Use styles={{ body: {...} }}
•❌ Modal: destroyOnClose → ✅ Use destroyOnHidden
•❌ Divider: orientation="left/right" → ✅ Use titlePlacement="left/right" (for text positioning)

Examples:

typescript

// ✅ Good - Use styles.body
<Card styles={{ body: { padding: token.paddingSM } }}>Content</Card>

// ✅ Good - Use destroyOnHidden
<Modal destroyOnHidden>Content</Modal>

// ✅ Good - Use titlePlacement for text positioning
<Divider titlePlacement="left">Section Title</Divider>

Component Tokens (Configured in Provider_ANTD)

Button and other components have component-level tokens set in Provider_ANTD.tsx. Do NOT override these with inline styles — use ANTD's size prop and let the tokens handle it:

typescript

// ❌ Bad — overrides component tokens with inline styles
<Button type="primary" style={{ borderRadius: 9999, fontSize: 16, fontWeight: 600, paddingInline: 24 }}>

// ✅ Good — component tokens handle radius, font, padding automatically
<Button type="primary" size="large">

Configured Button sizes (via component tokens):

•size="large" → 48px height, 16px font, 24px padding, pill shape
•size="middle" (default) → 32px height, 12px font, 16px padding, pill shape

Anti-Pattern Detection

Check for these violations before proceeding:

•❌ Hardcoded colors/spacing → ✅ Use theme.useToken() and token.*
•❌ import { message } from 'antd' → ✅ const { message } = App.useApp()
•❌ Plain HTML (<h1>, <p>) → ✅ ANTD Typography (<Title>, <Paragraph>)
•❌ Missing theme.useToken() hook → ✅ Import and use in component
•❌ Mixed icon libraries → ✅ Choose one (prefer @ant-design/icons)
•❌ New Radix/Tailwind → ✅ Use ANTD only
•❌ Deprecated props (bodyStyle, destroyOnClose, orientation on Divider) → ✅ Use new props
•❌ Inline styles that duplicate component tokens (borderRadius, fontSize, fontWeight, padding on Button) → ✅ Use size prop

If any violations are detected, point them out and ask the user to confirm before proceeding.
