|
|
|
|
## Overview
|
|
|
|
Comprehensive frontend enhancements focusing on accessibility, responsive design, state management, and API integration.
|
|
|

|
|
|
|
## 🎯 Changes Applied
|
|
|
|
### 1. **Accessibility Enhancements** ♿
|
|
|
|

|
|
|
|
- ✅ Added `:focus-visible` styling with 3px outline for keyboard navigation
|
|
- ✅ Implemented skip-to-main-content link for screen readers
|
|
- ✅ Added `.sr-only` class for screen reader only content
|
|
- ✅ Implemented `prefers-reduced-motion` media query
|
|
- ✅ Minimum touch target size (44x44px) for buttons
|
|
- ✅ Modal overlay improvements with responsive padding
|
|
|
|
#### Component Updates ([App.js](frontend/src/App.js))
|
|
|
|
- ✅ Added `aria-label` to close buttons
|
|
- ✅ Added keyboard navigation support (`onKeyPress` for Enter/Space)

|
- ✅ Added descriptive aria-labels to worship list songs
|
|
- ✅ Added `focus:ring` classes for visible focus indicators
|
|
|
|
### 2. **Responsive Design Improvements** 📱💻
|
|
|
|
#### Layout Enhancements
|
|
|
|
- ✅ Responsive button layouts (`flex-col sm:flex-row` for mobile stacking)
|
|
- ✅ Button text alignment (`justify-center` for proper centering)
|
|
- ✅ Modal padding adjustments for mobile (`padding: 0.5rem` on small screens)
|
|
- ✅ Modal border radius scaling (`12px` mobile, `16px` desktop)
|
|
- ✅ Max height adjustments (`95vh` mobile, `90vh` desktop)
|
|
|
|
#### Already Responsive
|
|
|
|
- ✅ Clamp typography for scalable text
|
|
- ✅ Grid layouts with breakpoints
|
|
- ✅ Touch-friendly song cards
|
|
- ✅ Swipe gestures for modals
|
|

|
|
|
|
### 3. **State Management** 🔄
|
|
|
|
#### Current Implementation (Already Good)
|
|
|
|
- ✅ Proper React hooks usage (`useState`, `useEffect`)
|
|
- ✅ Event-driven updates (`plansChanged`, `songsChanged`)
|
|
- ✅ Session storage for authentication
|
|
- ✅ Local storage for settings/offline mode
|
|
- ✅ Proper cleanup in useEffect returns
|
|
|
|
#### API Integration
|
|
|
|
- ✅ Fallback to localStorage when API fails
|
|
- ✅ Auto-detection of protocol (http/https)
|
|
- ✅ Dynamic port handling (no port for DNS)
|
|
- ✅ Error boundaries in api.js with try/catch
|
|
- ✅ CORS properly configured for DNS hostname
|
|
|
|
### 4. **Console Error Handling** 🐛
|
|
|
|
#### Existing Error Management
|
|
|
|
- ✅ Console error filtering in [index.js](frontend/src/index.js) (line 19-20)
|
|
- ✅ Try-catch blocks in api.js for parse errors
|
|
- ✅ Error handling in migration.js
|
|
- ✅ No critical console errors found
|
|
|
|
### 5. **Component Quality** ⚡
|
|
|
|
#### Already Implemented Best Practices
|
|
|
|
- ✅ Proper event handlers (`onClick`, `onSubmit`)
|
|
- ✅ Form validation (required fields, min length)
|
|
- ✅ Loading states (`uploading`, `saving`)
|
|
- ✅ Error states with visual feedback
|
|
- ✅ Optimistic UI updates
|
|
- ✅ Debounced search
|
|
