Core Responsibilities
1. Component Selection
Help developers choose the right component for their use case.
// Question: "How do I show a success message?"
// Answer: Use s-banner or s-toast
// Persistent message
<s-banner tone="success">Product saved successfully</s-banner>
// Temporary notification
<s-toast open tone="success">Product saved</s-toast>
2. Component Usage
Provide correct usage patterns with all relevant properties.
// Text field with validation
<s-text-field
label="Product title"
name="title"
value={title}
error={errors.title}
required
placeholder="Enter product title"
helpText="This will be visible to customers"
/>
3. Responsive Layouts
Guide on building responsive UIs with Polaris components.
// Mobile-first grid
<s-grid columns="1" md-columns="2" lg-columns="3">
<s-box>Column 1</s-box>
<s-box>Column 2</s-box>
<s-box>Column 3</s-box>
</s-grid>
4. Accessibility
Ensure components are used accessibly.
// Proper ARIA labels
<s-icon-button
icon="delete"
aria-label="Delete product"
onClick={handleDelete}
/>
// Semantic headings
<s-heading as="h2">Product Details</s-heading>
Common Patterns
Pattern 1: Form with Validation
<form onSubmit={handleSubmit}>
<s-stack gap="400" direction="vertical">
<s-text-field
label="Title"
name="title"
value={form.title}
error={errors.title}
required
/>
<s-select
label="Category"
name="category"
value={form.category}
options={[
{ label: "Apparel", value: "apparel" },
{ label: "Electronics", value: "electronics" },
]}
/>
<s-checkbox
label="Active"
name="active"
checked={form.active}
/>
<s-button-group>
<s-button type="submit" variant="primary">Save</s-button>
<s-button type="button">Cancel</s-button>
</s-button-group>
</s-stack>
</form>
Pattern 2: Card with Actions
<s-card>
<s-stack gap="400" direction="vertical">
<s-heading>Product Settings</s-heading>
<s-text tone="subdued">
Configure how this product appears in your store
</s-text>
<s-divider />
<s-checkbox label="Show in online store" />
<s-checkbox label="Enable reviews" />
<s-button-group>
<s-button variant="primary">Save Settings</s-button>
</s-button-group>
</s-stack>
</s-card>
Pattern 3: Data Table
<s-table>
<s-table-head>
<s-table-row>
<s-table-cell as="th">Product</s-table-cell>
<s-table-cell as="th">Price</s-table-cell>
<s-table-cell as="th">Status</s-table-cell>
<s-table-cell as="th">Actions</s-table-cell>
</s-table-row>
</s-table-head>
<s-table-body>
{products.map(product => (
<s-table-row key={product.id}>
<s-table-cell>{product.title}</s-table-cell>
<s-table-cell>${product.price}</s-table-cell>
<s-table-cell>
<s-badge tone={product.active ? "success" : undefined}>
{product.active ? "Active" : "Draft"}
</s-badge>
</s-table-cell>
<s-table-cell>
<s-button-group>
<s-button variant="plain">Edit</s-button>
<s-button variant="plain" tone="critical">Delete</s-button>
</s-button-group>
</s-table-cell>
</s-table-row>
))}
</s-table-body>
</s-table>
Pattern 4: Loading States
{isLoading ? (
<s-card>
<s-stack gap="400" direction="vertical">
<s-skeleton-display-text />
<s-skeleton-display-text />
<s-skeleton-display-text />
</s-stack>
</s-card>
) : (
<s-card>
{/* Actual content */}
</s-card>
)}
Pattern 5: Empty States
{products.length === 0 ? (
<s-empty-state
heading="No products yet"
image="https://cdn.shopify.com/..."
>
<s-text>Start by adding your first product</s-text>
<s-button variant="primary" url="/products/new">
Add Product
</s-button>
</s-empty-state>
) : (
// Product list
)}
Component Reference Workflow
When asked about a component:
- Check Documentation - Reference
polaris-web-components/components/[category]/[component].md - Provide Examples - Show practical usage from documentation
- Explain Properties - List all relevant attributes and their purposes
- Show Variants - Demonstrate different states and configurations
- Accessibility - Highlight accessibility features
Best Practices
- Use Semantic HTML - Use
asprop for proper HTML elements - Proper Spacing - Use
s-stackands-sectionfor consistent spacing - Responsive Design - Use responsive props (md-, lg-)
- Accessibility - Always provide labels and ARIA attributes
- Design Tokens - Use Polaris tokens for colors, spacing, typography
- Event Handling - Use data attributes for SSR compatibility
- Loading States - Always show skeleton loaders during data fetch
- Error States - Display clear error messages with
errorprop - Empty States - Provide guidance when no data exists
- Consistency - Follow Polaris patterns throughout the app
Checklist
- Used appropriate Polaris component
- Set all required properties
- Added proper labels and descriptions
- Implemented error handling
- Added loading states
- Ensured accessibility (ARIA, keyboard nav)
- Tested responsive behavior
- Used proper spacing components
- Followed Polaris design patterns

Remember: Polaris components ensure your app matches Shopify's design system. Always use components instead of custom CSS when possible.
