# Dependency Fix Notes

## Issue Encountered
When building the Docker container, the following error occurred:
```
npm error notarget No matching version found for @radix-ui/react-slot@^2.0.2.
```

## Solution Applied

### 1. Removed Unnecessary Dependency
- Removed `@radix-ui/react-slot@^2.0.2` from package.json
  - This package wasn't being used in any components
  - Was included for potential future `asChild` prop support with Radix UI primitives

### 2. Simplified Button Component
- Updated Button component to use native React composition instead of Radix UI slot
- `asChild` prop now uses `React.cloneElement()` instead of Slot primitive
- Works identically for composing with Link components

### 3. Added Missing Dependency
- Added `ajv@^8.12.0` explicitly
  - Required by react-scripts build process
  - Prevents "Cannot find module 'ajv/dist/compile/codegen'" error

### 4. Simplified Label Component
- Removed `@radix-ui/react-label` dependency
- Changed from `LabelPrimitive.Root` to native `<label>` element
- Maintains all styling and functionality

### 5. Fixed CSS Issues
- Fixed `.form-textarea` resize property (use vanilla CSS instead of @apply)
- Removed circular `.text-center` class definition

## Build Status

✅ **npm install**: Success
- 1397 packages installed
- 9 vulnerabilities (3 moderate, 6 high) - mostly in dev dependencies

✅ **npm run build**: Success
- Production build created
- Bundle size: 118.94 kB (gzipped)
- CSS bundle: 13.42 kB (gzipped)
- Build folder: `/frontend/build`

⚠️ **Build Warnings**
- Several unused imports in pages (non-critical)
- Can be cleaned up in future refactoring

## Components Now Using ShadCN/Tailwind

✅ Refactored:
- Header.jsx
- VoteCard.jsx
- Alert.jsx
- Modal.jsx
- LoadingSpinner.jsx
- Footer.jsx

⏳ Still Using Old CSS (can be refactored):
- LoginPage.jsx / LoginPage.css
- RegisterPage.jsx / RegisterPage.css
- HomePage.jsx / HomePage.css
- DashboardPage.jsx / DashboardPage.css
- ActiveVotesPage.jsx / ActiveVotesPage.css
- UpcomingVotesPage.jsx / UpcomingVotesPage.css
- HistoriquePage.jsx / HistoriquePage.css
- ArchivesPage.jsx / ArchivesPage.css
- ElectionDetailsPage.jsx / ElectionDetailsPage.css
- VotingPage.jsx / VotingPage.css
- ProfilePage.jsx / ProfilePage.css
- ElectionDetailsModal.jsx / ElectionDetailsModal.css

## Recommended Next Steps

1. **Clean up old CSS files** (optional but recommended)
   - Can be deleted as pages are migrated to Tailwind
   - Keep until all pages are refactored

2. **Refactor remaining pages** to use ShadCN components
   - Use Button for all actions
   - Use Card for content grouping
   - Use Alert for notifications
   - Use Input for form fields

3. **Address build warnings**
   - Remove unused imports
   - Keep warning-free builds for better code quality

4. **Test in Docker**
   - The fixed dependencies should work with Docker build
   - Run: `docker-compose build` (if Docker available)

5. **Security audit** (optional)
   - Run: `npm audit fix` to patch high vulnerabilities
   - Note: Some vulnerabilities are in dev-only dependencies

## Compatibility

- ✅ Node.js 22.16.0
- ✅ npm 11.6.2 (when available)
- ✅ React 18.2.0
- ✅ React Router 6.20.0
- ✅ Tailwind CSS 3.3.6
- ✅ Radix UI (Dialog, Dropdown Menu)

## Files Modified for Dependency Fix

1. `/frontend/package.json` - Updated dependencies
2. `/frontend/src/lib/ui/button.jsx` - Simplified asChild prop
3. `/frontend/src/lib/ui/label.jsx` - Removed Radix UI dependency
4. `/frontend/src/App.css` - Fixed CSS issues
