shopify-polaris-design（Shopify polaris 设计）

This skill ensures that interfaces are built using Shopify's Polaris Design System (React implementation v13.x), guaranteeing a native, accessible, and professional look and feel for Shopify Merchants.

Note (2025-2026): Polaris React (@shopify/polaris) is in maintenance mode. Shopify has introduced Polaris Web Components for new development. However, Polaris React remains fully functional and supported for existing applications. This guide covers the React implementation.

Core Principles

1. Merchant-Focused: Design for efficiency and clarity. Merchants use these tools to run their business.
2. Native Feel: The app should feel like a natural extension of the Shopify Admin. Do not introduce foreign design patterns (e.g. Material Design shadows, distinct bootstappy buttons) unless absolutely necessary.
3. Accessibility: Polaris is built with accessibility in mind. Maintain this by using semantic components (e.g., Button, Link, TextField) rather than custom div implementations.
4. Predictability: Follow standard Shopify patterns. Save buttons go in the App Bridge Save Bar. Page actions go in the top right. Primary content is centered.

Technical Implementation

Dependencies (v13.x - 2025-2026)

{
  "@shopify/polaris": "^13.9.0",
  "@shopify/polaris-icons": "^9.x",
  "@shopify/app-bridge-react": "^4.x"
}

App Bridge Integration (Critical for v13.x)

Many UI components are now handled by App Bridge instead of Polaris React:

// Example: Using App Bridge for Modal (instead of deprecated Polaris Modal)
import { Modal, TitleBar } from '@shopify/app-bridge-react';

function MyComponent() {
  return (
    <Modal id="my-modal">
      <TitleBar title="Confirm Action">
        <button variant="primary" onClick={handleConfirm}>Confirm</button>
        <button onClick={handleCancel}>Cancel</button>
      </TitleBar>
      <p>Are you sure you want to proceed?</p>
    </Modal>
  );
}

// Example: Using App Bridge for Toast
import { useAppBridge } from '@shopify/app-bridge-react';

function showToast() {
  shopify.toast.show('Product saved successfully');
}

// Example: Using App Bridge Save Bar
import { useSaveBar } from '@shopify/app-bridge-react';

function SettingsForm() {
  const saveBar = useSaveBar();

  useEffect(() => {
    if (hasChanges) {
      saveBar.show();
    } else {
      saveBar.hide();
    }
  }, [hasChanges]);
}

Fundamental Components

• AppProvider: All Polaris apps must be wrapped in <AppProvider i18n={enTranslations}>.
• Page: The top-level container for a route. Always set title and primaryAction (if applicable). <Page title="Products" primaryAction={{content: 'Add product', onAction: handleAdd}} backAction={{content: 'Settings', url: '/settings'}} > v13.x Note: backAction prop in Page.Header is deprecated. Use App Bridge navigation instead for complex navigation patterns.
• Layout: Use Layout and Layout.Section to structure content.

- Layout.AnnotatedSection: For settings pages (Title/Description on left, Card on right). - Layout.Section: Standard Full (default), 1/2 (variant="oneHalf"), or 1/3 (variant="oneThird") width columns.

• Card: The primary container for content pieces. Group related information in a Card.

- Use BlockStack (vertical) or InlineStack (horizontal) for internal layout within a Card. - Do not use LegacyCard - it is deprecated. Use Card with layout primitives.

Layout Primitives (Modern Pattern)

import { Box, BlockStack, InlineStack, InlineGrid, Bleed, Divider } from '@shopify/polaris';

// Box - Low-level layout primitive with full token access
<Box padding="400" background="bg-surface-secondary" borderRadius="200">
  Content here
</Box>

// BlockStack - Vertical stacking with gap
<BlockStack gap="400">
  <Item1 />
  <Item2 />
</BlockStack>

// InlineStack - Horizontal layout with alignment
<InlineStack gap="200" align="center" blockAlign="center">
  <Icon />
  <Text>Label</Text>
</InlineStack>

// InlineGrid - Responsive grid layout
<InlineGrid columns={{xs: 1, sm: 2, md: 3}} gap="400">
  <Card>...</Card>
  <Card>...</Card>
  <Card>...</Card>
</InlineGrid>

// Bleed - Negative margin for edge-to-edge content
<Card>
  <Bleed marginInline="400">
    <img src="banner.jpg" style={{width: '100%'}} />
  </Bleed>
</Card>

Data Display

• IndexTable: For lists of objects (Products, Orders) with bulk actions and filtering. import {IndexTable, Card, Text, Badge, useIndexResourceState} from '@shopify/polaris'; function ProductList({products}) {const {selectedResources, allResourcesSelected, handleSelectionChange} = useIndexResourceState(products); const rowMarkup = products.map((product, index) => (<IndexTable.Row id={product.id} key={product.id} selected={selectedResources.includes(product.id)} position={index} > <IndexTable.Cell> <Text variant="bodyMd" fontWeight="bold">{product.name}</Text> </IndexTable.Cell> <IndexTable.Cell>{product.sku}</IndexTable.Cell> <IndexTable.Cell> <Badge tone={product.status === 'active'? 'success': 'info'}> {product.status} </Badge> </IndexTable.Cell> </IndexTable.Row>)); return (<Card padding="0"> <IndexTable resourceName={{singular: 'product', plural: 'products'}} itemCount={products.length} selectedItemsCount={allResourcesSelected? 'All': selectedResources.length} onSelectionChange={handleSelectionChange} headings={[{title: 'Name'}, {title: 'SKU'}, {title: 'Status'},]} > {rowMarkup} </IndexTable> </Card>);}
• DataTable: For simple, non-interactive data grids (e.g., analytics data).
• ResourceList: For simpler lists without table structure (use ResourceItem for each item).

Form Design

import {
  Form, FormLayout, TextField, Select, Checkbox,
  ChoiceList, RadioButton, RangeSlider, ColorPicker,
  DropZone, Tag, Autocomplete
} from '@shopify/polaris';

function ProductForm() {
  const [formState, setFormState] = useState({
    title: '',
    description: '',
    status: 'draft',
    tags: [],
  });
  const [errors, setErrors] = useState({});

  return (
    <Form onSubmit={handleSubmit}>
      <FormLayout>
        <TextField
          label="Product title"
          value={formState.title}
          onChange={(value) => setFormState({...formState, title: value})}
          error={errors.title}
          autoComplete="off"
          helpText="This will be displayed to customers"
        />

        <TextField
          label="Description"
          value={formState.description}
          onChange={(value) => setFormState({...formState, description: value})}
          multiline={4}
          autoComplete="off"
        />

        <Select
          label="Status"
          options={[
            {label: 'Draft', value: 'draft'},
            {label: 'Active', value: 'active'},
            {label: 'Archived', value: 'archived'},
          ]}
          value={formState.status}
          onChange={(value) => setFormState({...formState, status: value})}
        />

        <FormLayout.Group>
          <TextField label="Price" type="number" prefix="$" />
          <TextField label="Compare at price" type="number" prefix="$" />
        </FormLayout.Group>

        <ChoiceList
          title="Availability"
          choices={[
            {label: 'Online Store', value: 'online'},
            {label: 'Point of Sale', value: 'pos'},
            {label: 'Buy Button', value: 'buy_button'},
          ]}
          selected={formState.channels}
          onChange={(value) => setFormState({...formState, channels: value})}
          allowMultiple
        />
      </FormLayout>
    </Form>
  );
}

Filters & Search (IndexFilters)

import {
  IndexFilters, useSetIndexFiltersMode, IndexFiltersMode,
  ChoiceList, RangeSlider, TextField
} from '@shopify/polaris';

function FilteredList() {
  const [queryValue, setQueryValue] = useState('');
  const [status, setStatus] = useState([]);
  const { mode, setMode } = useSetIndexFiltersMode(IndexFiltersMode.Filtering);

  const filters = [
    {
      key: 'status',
      label: 'Status',
      filter: (
        <ChoiceList
          title="Status"
          titleHidden
          choices={[
            {label: 'Active', value: 'active'},
            {label: 'Draft', value: 'draft'},
            {label: 'Archived', value: 'archived'},
          ]}
          selected={status}
          onChange={setStatus}
          allowMultiple
        />
      ),
      shortcut: true,
    },
  ];

  const appliedFilters = status.length > 0
    ? [{key: 'status', label: `Status: ${status.join(', ')}`}]
    : [];

  return (
    <IndexFilters
      queryValue={queryValue}
      queryPlaceholder="Search products"
      onQueryChange={setQueryValue}
      onQueryClear={() => setQueryValue('')}
      filters={filters}
      appliedFilters={appliedFilters}
      onClearAll={() => setStatus([])}
      mode={mode}
      setMode={setMode}
      tabs={[
        {content: 'All', id: 'all'},
        {content: 'Active', id: 'active'},
        {content: 'Draft', id: 'draft'},
      ]}
      selected={0}
    />
  );
}

Design Tokens & CSS (v13.x)

Deprecated Components (v13.x) - DO NOT USE

These components will be removed in future versions:

Code Style Example (v13.x Best Practices)

import {
  Page, Layout, Card, BlockStack, InlineStack,
  Text, Button, Badge, Box, Divider, Banner,
  IndexTable, useIndexResourceState
} from '@shopify/polaris';
import { ExportIcon, PlusIcon } from '@shopify/polaris-icons';

export default function Dashboard({ products }) {
  const { selectedResources, allResourcesSelected, handleSelectionChange } =
    useIndexResourceState(products);

  const promotedBulkActions = [
    { content: 'Export selected', icon: ExportIcon },
  ];

  const rowMarkup = products.map((product, index) => (
    <IndexTable.Row
      id={product.id}
      key={product.id}
      selected={selectedResources.includes(product.id)}
      position={index}
    >
      <IndexTable.Cell>
        <Text variant="bodyMd" fontWeight="bold">{product.title}</Text>
      </IndexTable.Cell>
      <IndexTable.Cell>
        <Badge tone={product.status === 'active' ? 'success' : 'info'}>
          {product.status}
        </Badge>
      </IndexTable.Cell>
      <IndexTable.Cell>${product.price}</IndexTable.Cell>
    </IndexTable.Row>
  ));

  return (
    <Page
      title="Dashboard"
      primaryAction={{
        content: 'Add product',
        icon: PlusIcon,
        onAction: () => {}
      }}
      secondaryActions={[
        {content: 'Export', icon: ExportIcon, onAction: () => {}}
      ]}
    >
      <Layout>
        <Layout.Section>
          <Banner tone="info" onDismiss={() => {}}>
            <p>New: Try our improved bulk editing features.</p>
          </Banner>
        </Layout.Section>

        <Layout.Section>
          <Card padding="0">
            <IndexTable
              resourceName={{singular: 'product', plural: 'products'}}
              itemCount={products.length}
              selectedItemsCount={allResourcesSelected ? 'All' : selectedResources.length}
              onSelectionChange={handleSelectionChange}
              headings={[
                {title: 'Product'},
                {title: 'Status'},
                {title: 'Price', alignment: 'end'},
              ]}
              promotedBulkActions={promotedBulkActions}
            >
              {rowMarkup}
            </IndexTable>
          </Card>
        </Layout.Section>

        <Layout.Section variant="oneThird">
          <Card>
            <BlockStack gap="400">
              <Text as="h2" variant="headingMd">Quick Stats</Text>
              <Divider />
              <BlockStack gap="200">
                <InlineStack align="space-between">
                  <Text tone="subdued">Total products</Text>
                  <Text fontWeight="semibold">{products.length}</Text>
                </InlineStack>
                <InlineStack align="space-between">
                  <Text tone="subdued">Active</Text>
                  <Text fontWeight="semibold">
                    {products.filter(p => p.status === 'active').length}
                  </Text>
                </InlineStack>
              </BlockStack>
            </BlockStack>
          </Card>

          <Box paddingBlockStart="400">
            <Card>
              <BlockStack gap="300">
                <Text as="h3" variant="headingSm">Quick Actions</Text>
                <Button variant="plain" url="/settings">
                  View all settings
                </Button>
              </BlockStack>
            </Card>
          </Box>
        </Layout.Section>
      </Layout>
    </Page>
  );
}

Anti-Patterns to AVOID

• DO NOT use deprecated components (LegacyCard, Modal, Toast, etc.).
• DO NOT use Shadows or Borders manually. Cards handle this.
• DO NOT use style={{margin: 10}}. Use <Box padding="400"> or <BlockStack gap="400">.
• DO NOT create a "Save" button at the bottom of a form. Use App Bridge Save Bar.
• DO NOT use generic loading spinners. Use <SkeletonPage> or <SkeletonBodyText> for loading states.
• DO NOT use <h1>, <h2>, etc. directly. Use <Text as="h2" variant="headingMd">.
• DO NOT use inline styles. Use Box/BlockStack props or design tokens.
• DO NOT import from @shopify/polaris/build/esm/.... Use named exports from @shopify/polaris.

Internationalization Support (v13.10+)

Polaris v13.10 added translations for 8 new languages: Hindi, Lithuanian, Bulgarian, Hungarian, Romanian, Russian, Indonesian, and Greek.

import enTranslations from '@shopify/polaris/locales/en.json';
import viTranslations from '@shopify/polaris/locales/vi.json';

// Use the appropriate translations based on merchant locale
<AppProvider i18n={merchantLocale === 'vi' ? viTranslations : enTranslations}>
  <App />
</AppProvider>
