Implemented context-aware back button that respects user's navigation path:
Pattern:
```typescript
const handleBack = () => {
if (window.history.state?.idx > 0) {
navigate(-1); // Go back in history
} else {
navigate('/fallback'); // Safe fallback
}
};
```
Updated Pages:
✅ Orders/Detail.tsx → Fallback: /orders
✅ Orders/Edit.tsx → Fallback: /orders/:id
✅ Customers/Detail.tsx → Fallback: /customers
✅ Customers/Edit.tsx → Fallback: /customers
✅ Products/Edit.tsx → Fallback: /products
✅ Coupons/Edit.tsx → Fallback: /coupons
User Flow Examples:
1. Normal Navigation (History Available):
Customers Index → Customer Detail → Orders Tab → Order Detail
→ Click Back → Returns to Customer Detail ✅
2. Direct Access (No History):
User opens /orders/360 directly
→ Click Back → Goes to /orders (fallback) ✅
3. New Tab (No History):
User opens order in new tab
→ Click Back → Goes to /orders (fallback) ✅
4. Page Refresh (History Cleared):
User refreshes page
→ Click Back → Goes to fallback ✅
Benefits:
✅ Respects user's navigation path when possible
✅ Never breaks or leaves the app
✅ Predictable behavior in all scenarios
✅ Professional UX (like Gmail, Shopify, etc.)
✅ Works with deep links and bookmarks
Technical:
- Uses window.history.state.idx to detect history
- Falls back to safe default when no history
- Consistent pattern across all pages
- No URL parameters needed
Result: Back button now works intelligently based on context!
Fixed eslint error: "Cannot find name 'nav'"
Issue:
- Detail.tsx was using nav variable in useEffect
- useNavigate hook was not imported
- nav variable was not declared
Fix:
- Added useNavigate to imports from react-router-dom
- Declared nav variable: const nav = useNavigate()
Result:
✅ Zero eslint errors in Detail.tsx
✅ All Orders module files pass eslint
Implemented proper contextual header pattern for all Order CRUD pages.
Problem:
- New/Edit pages had action buttons at bottom of form
- Detail page showed duplicate headers (contextual + inline)
- Not following mobile-first best practices
Solution: [Back] Page Title [Action]
1. Edit Order Page
Header: [Back] Edit Order #337 [Save]
Implementation:
- Added formRef to trigger form submit from header
- Save button in contextual header
- Removed submit button from form bottom
- Button shows loading state during save
Changes:
- Edit.tsx: Added formRef, updated header with Save button
- OrderForm.tsx: Added formRef and hideSubmitButton props
- Form submit triggered via formRef.current.requestSubmit()
2. New Order Page
Header: [Back] New Order [Create]
Implementation:
- Added formRef to trigger form submit from header
- Create button in contextual header
- Removed submit button from form bottom
- Button shows loading state during creation
Changes:
- New.tsx: Added formRef, updated header with Create button
- Same OrderForm props as Edit page
3. Order Detail Page
Header: (hidden)
Implementation:
- Cleared contextual header completely
- Detail page has its own inline header with actions
- Inline header: [Back] Order #337 [Print] [Invoice] [Label] [Edit]
Changes:
- Detail.tsx: clearPageHeader() in useEffect
- No duplicate headers
OrderForm Component Updates:
- Added formRef prop (React.RefObject<HTMLFormElement>)
- Added hideSubmitButton prop (boolean)
- Form element accepts ref: <form ref={formRef}>
- Submit button conditionally rendered: {!hideSubmitButton && <Button...>}
- Backward compatible (both props optional)
Benefits:
✅ Consistent header pattern across all CRUD pages
✅ Action buttons always visible (sticky header)
✅ Better mobile UX (no scrolling to find buttons)
✅ Loading states in header buttons
✅ Clean, modern interface
✅ Follows industry standards (Gmail, Notion, Linear)
Files Modified:
- routes/Orders/New.tsx
- routes/Orders/Edit.tsx
- routes/Orders/Detail.tsx
- routes/Orders/partials/OrderForm.tsx
Result:
✅ New/Edit: Action buttons in contextual header
✅ Detail: No contextual header (has inline header)
✅ Professional, mobile-first UX! 🎯
