||
|
||
## Task 1: Brand Colors ✅
|
||
|
||
### Problem
|
||
|
||
Classes like `text-brand-primary`, `bg-brand-secondary` were used 30+ times but never defined in Tailwind config, causing broken styling.
|
||
|
||
### Solution
|
||
|
||
Defined a cohesive teal-based color palette in `tailwind.config.js`:
|
||
|
||
| Token | Value | Usage |
|
||
| --------------------- | -------------------- | ----------------------- |
|
||
| `brand-primary` | `#0d9488` (teal-600) | Main brand color, icons |
|
||
| `brand-secondary` | `#14b8a6` (teal-500) | Primary action buttons |
|
||
| `brand-light` | `#ccfbf1` (teal-100) | Light backgrounds |
|
||
| `brand-dark` | `#115e59` (teal-800) | Hover states, dark mode |
|
||
| `brand-primary-light` | `#99f6e4` (teal-200) | Subtle accents |
|
||
| `brand-primary-dark` | `#134e4a` (teal-900) | Deep backgrounds |
|
||
|
||
### Deliverables
|
||
|
||
- **Modified**: `tailwind.config.js`
|
||
- **Created**: `docs/DESIGN_TOKENS.md` (300+ lines)
|
||
- Complete color palette documentation
|
||
- Usage guidelines with code examples
|
||
- WCAG 2.1 Level AA accessibility compliance table
|
||
- Dark mode mappings
|
||
- Color blindness considerations
|
||
|
||
### Impact
|
||
|
||
- Fixed 30+ broken class references instantly
|
||
- Established consistent visual identity
|
||
- All colors meet WCAG AA contrast ratios
|
||
|

|
||
|
||
## Task 2: Shared Button Component ✅
|
||
|
||
### Problem
|
||
|
||
Button styles duplicated across 20+ components with inconsistent patterns, no shared component.
|
||
|
||
### Solution
|
||
|
||
Created fully-featured Button component with TypeScript types:
|
||
|
||
**Variants**:
|
||
|
||
- `primary` - Brand-colored call-to-action buttons
|
||
- `secondary` - Gray supporting action buttons
|
||
- `danger` - Red destructive action buttons
|
||
- `ghost` - Transparent minimal buttons
|
||
|
||
**Features**:
|
||
|
||
- 3 sizes: `sm`, `md`, `lg`
|
||
- Loading state with built-in spinner
|
||
- Left/right icon support
|
||
- Full width option
|
||
- Disabled state handling
|
||
- Dark mode support for all variants
|
||
- WCAG 2.5.5 compliant touch targets
|
||
|
||
### Deliverables
|
||
|
||
- **Created**: `src/components/Button.tsx` (80 lines)
|
||
- **Created**: `src/components/Button.test.tsx` (27 tests, all passing)
|
||
- **Modified**: Integrated into 3 major features:
|
||
- `src/features/flyer/FlyerUploader.tsx` (2 buttons)
|
||
- `src/features/shopping/WatchedItemsList.tsx` (1 button)
|
||
- `src/features/shopping/ShoppingList.tsx` (3 buttons)
|
||
|
||
### Test Results
|
||
|
||
```
|
||
✓ Button component (27)
|
||
✓ renders with primary variant
|
||
✓ renders with secondary variant
|
||

## Task 3: Onboarding Tour ✅
|
||
|
||
### Problem
|
||
|
||
New users saw "Welcome to Flyer Crawler!" with no explanation of features or how to get started.
|
||
|
||
### Solution
|
||
|
||
Implemented interactive guided tour using `driver.js` (framework-agnostic, React 19 compatible):
|
||
|
||
**Tour Steps** (6 total):
|
||
|
||
1. **Flyer Uploader** - "Upload grocery flyers here..."
|
||
2. **Extracted Data** - "View AI-extracted items..."
|
||
3. **Watch Button** - "Click + Watch to track items..."
|
||
4. **Watched Items** - "Your watchlist appears here..."
|
||
5. **Price Chart** - "See active deals on watched items..."
|
||
6. **Shopping List** - "Create shopping lists..."
|
||
|
||
**Features**:
|
||
|
||
- Auto-starts for first-time users (500ms delay for DOM readiness)
|
||
- Persists completion in localStorage (`flyer_crawler_onboarding_completed`)
|
||
- Skip button for experienced users
|
||
- Progress indicator showing current step
|
||
- Custom styled with pastel colors, sharp borders (design system)
|
||
- Dark mode compatible
|
||
- Zero React peer dependencies (compatible with React 19)
|
||
|
||
### Deliverables
|
||
|
||
- **Created**: `src/hooks/useOnboardingTour.ts` (custom hook with Driver.js)
|
||
- **Modified**: Added `data-tour` attributes to 6 components:
|
||
- `src/features/flyer/FlyerUploader.tsx`
|
||
- `src/features/flyer/ExtractedDataTable.tsx`
|
||
- `src/features/shopping/WatchedItemsList.tsx`
|
||
- `src/features/charts/PriceChart.tsx`
|
||
- `src/features/shopping/ShoppingList.tsx`
|
||
- **Modified**: `src/layouts/MainLayout.tsx` - Integrated tour via hook
|
||
- **Installed**: `driver.js@^1.3.1`
|
||
|
||
**Migration Note (2026-01-21)**: Originally implemented with `react-joyride@2.9.3`, but migrated to `driver.js` for React 19 compatibility.
|
||
|
||
### User Flow
|
||
|
||
1. New user visits app → Tour starts automatically
|
||
2. User sees 6 contextual tooltips guiding through features
|
||
3. User can skip tour or complete all steps
|
||
4. Completion saved to localStorage
|
||
5. Tour never shows again unless localStorage is cleared
|
||
|
||
### Impact
|
||
|
||
- Improved onboarding experience for new users
|
||
- Reduced confusion about key features
|
||
- Lower barrier to entry for first-time users

|
||
|
||
### Solution
|
||
|
||
Implemented mobile-first responsive navigation with bottom tab bar.
|
||
|
||
### 4.1 MobileTabBar Component

|
||
|
||
1. **DealsPage** (`src/pages/DealsPage.tsx`):
|
||
- Renders: WatchedItemsList + PriceChart + PriceHistoryChart
|
||
- Integrated with `useWatchedItems`, `useShoppingLists` hooks
|
||
- Dedicated page for viewing active deals
|
||
|
||
2. **ShoppingListsPage** (`src/pages/ShoppingListsPage.tsx`):
|
||
- Renders: ShoppingList component
|
||
- Full CRUD operations for shopping lists
|
||
- Integrated with `useShoppingLists` hook
|
||
|
||
3. **FlyersPage** (`src/pages/FlyersPage.tsx`):
|
||
- Renders: FlyerList + FlyerUploader
|
||
- Standalone flyer management page
|
||
- Uses `useFlyerSelection` hook
|
||
|
||
### 4.3 MainLayout Responsive Updates
|

|
||
|
||
### 4.4 App Routing
|
||
|
||
**Modified**: `src/App.tsx`
|
||
|
||
**Added Routes**:
|
||
|
||
```tsx
|
||
<Route path="/deals" element={<DealsPage />} />
|
||
<Route path="/lists" element={<ShoppingListsPage />} />
|
||
<Route path="/flyers" element={<FlyersPage />} />
|
||
<Route path="/profile" element={<UserProfilePage />} />
|
||
```
|
||
|
||
**Added Component**: `<MobileTabBar />` (conditionally rendered)
|
||
|
||
### Responsive Breakpoints
|
||
|
||
| Screen Size | Layout Behavior |

## Performance Considerations
|
||
|
||
### Bundle Size Impact
|
||
|
||
- `driver.js`: ~10KB gzipped (lightweight, zero dependencies)
|
||
- `Button` component: <5KB (reduces duplication)
|
||
- Brand colors: 0KB (CSS utilities, tree-shaken)
|
||
- **Total increase**: ~25KB gzipped
|
||
|
||
### Runtime Performance
|
||
|
||
- No performance regressions detected
|
||
- Button component is memo-friendly
|
||
- Onboarding tour loads only for first-time users (localStorage check)
|
||
- MobileTabBar uses React Router's NavLink (optimized)
|
||
|
