This action cannot be undone.", primaryAction: "Delete", destructive: true, }); if (confirmed) { await deleteProduct(); } } ``` ### Custom Modal ```tsx setModalOpen(false)} title="Edit Product" >

setModalOpen(false)}>Cancel

Save

``` ## 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

{/* App content */}

; } ``` ### 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 ## App Bridge API Reference ```typescript // Global shopify object shopify.resourcePicker({ type, multiple }) shopify.modal.confirm({ title, message, primaryAction, destructive }) shopify.toast.show(message, { duration, isError }) shopify.navigate(path) shopify.saveBar.show({ saveAction, discardAction }) shopify.saveBar.hide() ``` --- **Remember**: App Bridge creates a native Shopify experience. Use it to make your app feel integrated with the Shopify Admin.
