## App Bridge Setup

### Initialize App Bridge
|
|
```html
|
|
<head>
|
|
<meta name="shopify-api-key" content="%SHOPIFY_API_KEY%" />
|
|
<script src="https://cdn.shopify.com/shopifycloud/app-bridge.js"></script>

|
### App Window Component
|
|
```tsx
|
|
<s-app-window config={{ apiKey: process.env.SHOPIFY_API_KEY }}>
|
|
{/* Your app content */}
|
|
</s-app-window>
|
|
```
|
|
|
|
## Navigation Patterns
|
|
|
|
### Title Bar with Breadcrumbs
|
|
```tsx
|
|
<s-title-bar title="Product Details">
|
|
<s-breadcrumbs>
|
|
<s-link url="/app/products">Products</s-link>
|
|
</s-breadcrumbs>
|
|
|
|
<s-button variant="primary" onclick={handleSave}>
|
|
Save
|
|
</s-button>
|
|
|
|
<s-action-list>
|
|
<s-button variant="plain" onclick={handleDuplicate}>Duplicate</s-button>
|
|
<s-button variant="plain" tone="critical" onclick={handleDelete}>Delete</s-button>
|
|
</s-action-list>
|
|
</s-title-bar>
|
|
```
|
|
|
|
### App Navigation
|
|
```tsx
|
|
<s-app-nav>
|
|
<s-link url="/app" active>Dashboard</s-link>
|
|
<s-link url="/app/products">Products</s-link>
|
|
<s-link url="/app/orders">Orders</s-link>
|
|
<s-link url="/app/customers">Customers</s-link>
|
|
<s-link url="/app/settings">Settings</s-link>
|
|
</s-app-nav>
|
|
```
|
|
|
|
## Resource Pickers
|
|
|
|
### Product Picker
|
|
```tsx
|
|
function ProductSelector() {
|
|
const [selectedProducts, setSelectedProducts] = useState([]);
|
|
|
|
async function openProductPicker() {
|
|
const selected = await shopify.resourcePicker({
|
|
type: "product",
|
|
multiple: true,
|
|
});
|
|
|
|
if (selected) {
|
|
setSelectedProducts(selected);
|
|
}
|
|
}
|
|
|
|
return (
|
|
<>
|
|
<s-button onclick={openProductPicker}>
|
|
Select Products
|
|
</s-button>
|
|
|
|
{selectedProducts.length > 0 && (
|
|
<s-stack gap="200" direction="vertical">
|
|
{selectedProducts.map(product => (
|
|
<s-text key={product.id}>{product.title}</s-text>
|
|
))}
|
|
</s-stack>
|
|
)}
|
|
</>
|
|
);
|
|
}
|
|
```
|
|
|
|
### Variant Picker
|
|
```tsx
|
|
async function selectVariants() {
|
|
const selected = await shopify.resourcePicker({
|
|
type: "variant",
|
|
multiple: true,
|
|
});
|
|
|
|
return selected;
|
|
}
|
|
```
|
|
|
|
### Collection Picker
|
|
```tsx
|
|
async function selectCollection() {
|
|
const selected = await shopify.resourcePicker({
|
|
type: "collection",
|
|
multiple: false,
|
|
});
|
|
|
|
return selected;
|
|
}
|
|
```
|
|
|
|
## Modal Patterns
|
|
|
|
### Confirmation Modal
|
|
```tsx
|
|
async function confirmDelete() {
|
|
const confirmed = await shopify.modal.confirm({
|
|
title: "Delete Product",
|
|
message: "Are you sure you want to delete this product? This action cannot be undone.",
|
|
primaryAction: "Delete",
|
|
destructive: true,
|
|
});
|
|
|
|
if (confirmed) {
|
|
await deleteProduct();
|
|
}
|
|
}
|
|
```
|
|
|
|
### Custom Modal
|
|
```tsx
|
|
<s-modal
|
|
open={modalOpen}
|
|
onClose={() => setModalOpen(false)}
|
|
title="Edit Product"
|
|
>
|
|
<s-modal-section>
|
|
<s-stack gap="400" direction="vertical">
|
|
<s-text-field label="Title" value={title} />
|
|
<s-text-field label="Description" multiline={4} />
|
|
</s-stack>
|
|
</s-modal-section>
|
|
|
|
<s-modal-footer>
|
|
<s-button-group>
|
|
<s-button onclick={() => setModalOpen(false)}>Cancel</s-button>
|
|
<s-button variant="primary" onclick={handleSave}>Save</s-button>
|
|
</s-button-group>
|
|
</s-modal-footer>
|
|
</s-modal>
|
|
```
|
|
|
|
## Toast Notifications
|
|
|
|
### Success Toast
|
|
```tsx
|
|
function showSuccessToast() {
|
|
shopify.toast.show("Product saved successfully", {
|
|
duration: 3000,
|
|
});
|
|
}
|
|
```
|
|
|
|
### Error Toast
|
|
```tsx
|
|
function showErrorToast() {
|
|
shopify.toast.show("Failed to save product", {
|
|
duration: 5000,
|
|
isError: true,
|
|
});
|
|
}
|
|
```
|
|
|
|
## Navigation Events
|
|
|
|
### Handle Internal Navigation
|
|
```tsx
|
|
import { useNavigate } from "@remix-run/react";
|
|
|
|
export default function App() {
|
|
const navigate = useNavigate();
|
|
|
|
useEffect(() => {
|
|
// Listen for Shopify navigation events
|
|
function handleNavigate(event) {
|
|
const href = event.target.getAttribute("href");
|
|
if (href) {
|
|
navigate(href);
|
|
}
|
|
}
|
|
|
|
document.addEventListener("shopify:navigate", handleNavigate);
|
|
|
|
return () => {
|
|
document.removeEventListener("shopify:navigate", handleNavigate);
|
|
};
|
|
}, [navigate]);
|
|
|
|
return <div>{/* App content */}</div>;
|
|
}
|
|
```
|
|
|
|
### Programmatic Navigation
|
|
```tsx
|
|
function navigateToProduct(productId) {
|
|
shopify.navigate(`/app/products/${productId}`);
|
|
}
|
|
```
|
|
|
|
## Context Bar (Save Bar)
|
|
|
|
### Show Save Bar
|
|
```tsx
|
|
function ProductEditPage() {
|
|
const [hasChanges, setHasChanges] = useState(false);
|
|
|
|
useEffect(() => {
|
|
if (hasChanges) {
|
|
shopify.saveBar.show({
|
|
saveAction: {
|
|
label: "Save",
|
|
onAction: () => handleSave(),
|
|
},
|
|
discardAction: {
|
|
label: "Discard",
|
|
onAction: () => handleDiscard(),
|
|
},
|
|
});
|
|
} else {
|
|
shopify.saveBar.hide();
|
|
}
|
|
}, [hasChanges]);
|
|
|
|
return (
|
|
// Form fields...
|
|
);
|
|
}
|
|
```
|
|
|
|
## Best Practices
|
|
|
|
1. **Initialize App Bridge** - Always include App Bridge scripts in your app
|
|
2. **Use Native Components** - Leverage native title bar, modals, and toasts
|
|
3. **Resource Pickers** - Use native pickers for selecting Shopify resources
|
|
4. **Navigation Events** - Handle shopify:navigate for proper routing
|
|
5. **Save Bar** - Show save bar for forms with unsaved changes
|
|
6. **Consistent UX** - Match Shopify Admin's navigation patterns
|
|
7. **Error Handling** - Use toast notifications for user feedback
|
|
8. **Loading States** - Show loading indicators during async operations
|
|
9. **Confirmation Dialogs** - Use modal.confirm for destructive actions
|
|
10. **Mobile Support** - Test App Bridge features on mobile
|
|
|
|
