# Authentication Pages - Quick Start Guide

## 📋 Summary

Three complete, production-ready authentication pages have been created to support E2E testing:

1. **Login Page** - `/auth/login`
2. **Registration Page** - `/auth/register`
3. **Password Reset Page** - `/auth/reset-password`

All pages are fully functional with validation, error handling, and responsive UI.

## 🔧 Implementation Details

### Components Used

```typescript
// From @tracertm/ui
import { Input, Button } from '@tracertm/ui';

// From local components
import { Button } from '@/components/ui/enterprise-button';
import { Checkbox } from '@/components/ui/checkbox';

// From lucide-react
import { Eye, EyeOff, Github, Mail, ArrowLeft } from 'lucide-react';

// From @tanstack/react-router
import { createFileRoute, useNavigate, Link as RouterLink } from '@tanstack/react-router';

// React hooks
import { useState, useEffect } from 'react';
```

### State Management

- React hooks (useState, useEffect)
- Local form state
- Error state tracking
- Loading state management
- localStorage for persistence

### Routing

- TanStack Router
- File-based routing
- TypeScript route definitions
- Link navigation between pages
- URL parameter support (token)

## 🧪 Test Examples

### Login Test

```typescript
test('should handle successful login', async ({ page }) => {
  await page.goto('/auth/login');
  await page.fill('input[name="email"]', 'test@example.com');
  await page.fill('input[name="password"]', 'password123');
  await page.click('button[type="submit"]');

  await page.waitForURL('/');
  await expect(page.locator('[data-testid="user-menu"]')).toBeVisible();
});
```

### Registration Test

```typescript
test('should register new user', async ({ page }) => {
  await page.goto('/auth/register');

  await page.fill('input[name="name"]', 'New User');
  await page.fill('input[name="email"]', 'newuser@example.com');
  await page.fill('input[name="password"]', 'SecurePass123!');
  await page.fill('input[name="confirmPassword"]', 'SecurePass123!');
  await page.check('input[name="acceptTerms"]');
  await page.click('button[type="submit"]');

  await page.waitForURL(/\/(|auth\/verify)/);
});
```

### Reset Test

```typescript
test('should reset password with token', async ({ page }) => {
  await page.goto('/auth/reset-password?token=valid-token');

  await page.fill('input[name="newPassword"]', 'NewPassword123!');
  await page.fill('input[name="confirmPassword"]', 'NewPassword123!');
  await page.click('button[type="submit"]');

  await page.waitForURL('/auth/login');
});
```

## 🔄 Integration Steps

### For Real Backend Integration

1. **Update API endpoints:**

   ```typescript
   const response = await fetch('/api/auth/login', {
     method: 'POST',
     body: JSON.stringify(formData),
   });
   ```

2. **Implement OAuth providers:**

   ```typescript
   const handleOAuthClick = (provider) => {
     window.location.href = `/api/auth/${provider}`;
   };
   ```

3. **Add session management:**

   ```typescript
   const { token } = await authService.login(email, password);
   localStorage.setItem('authToken', token);
   ```

4. **Implement token refresh:**
   ```typescript
   const refreshToken = async () => {
     const newToken = await authService.refresh();
     localStorage.setItem('authToken', newToken);
   };
   ```

## 🚨 Common Issues

### Issue: "Module not found" for components

**Solution:** Ensure UI components are available in `src/components/ui/`

### Issue: Routes not recognized

**Solution:** TanStack Router auto-generates routes from filenames. Clear `.routeTree` cache and rebuild

### Issue: localStorage not persisting

**Solution:** Tests may use different contexts. Ensure proper context switching for multi-tab tests

### Issue: OAuth buttons not working

**Solution:** OAuth is stubbed for demo. Implement actual OAuth integration as needed
