🚀 Getting Started

1. Install Dependencies

npm install

2. Configure Backend URL

Create/update .env.local:

NEXT_PUBLIC_API_URL=http://localhost:8000

3. Start Development Server

npm run dev

4. Visit Login Page

http://localhost:3000/login

🔐 Key Security Features

✅ HTTP-Only Cookies - Token never exposed to JavaScript
✅ CSRF Protection - SameSite cookie policy
✅ Middleware Validation - Routes protected server-side
✅ Multi-tenant Support - Tenant isolation enforced by backend
✅ Role-based Access - Granular permission control
✅ Session Invalidation - Immediate logout

🧠 How It Works

Login Flow

User → /login page
    ↓ (enters credentials)
POST /api/auth/login
    ↓ (backend validates)
Sets auth_token cookie (HTTP-only)
    ↓ (redirects)
/recruitment dashboard
    ↓ (loads with auth)
User info from /admin/me

Access Control

Middleware checks cookie
    ↓
Valid token? → Allow access
    ↓
No token? → Redirect /login

💡 Usage Examples

Get Current User

import { useAuth } from '@/lib/auth-context';

const { user } = useAuth();
console.log(user?.username); // "admin"

Check Role

import { hasRole } from '@/lib/rbac';

if (hasRole(user, 'admin')) {
  // Show admin UI
}

Logout

const { logout } = useAuth();
logout(); // Clears cookie, redirects to /login

🔗 API Endpoints

Method	Path	Purpose
POST	/api/auth/login	Exchange credentials for token
POST	/api/auth/logout	Clear session
GET	/api/auth/me	Get current user

✅ Testing

Quick test checklist:

1. Login: Visit http://localhost:3000/login
2. Credentials: Enter your admin username/password
3. Verify: Should redirect to /recruitment
4. Cookies: Check DevTools → Cookies → auth_token (httpOnly)
5. Reload: Page should stay on /recruitment (session persists)
6. Logout: Click logout in header
7. Verify: Redirects to /login, cookie deleted

See TESTING_GUIDE.md for detailed test cases.

🛡️ Security Highlights

What's Protected

• ✅ Token in HTTP-only cookie (XSS protection)
• ✅ Routes validated by middleware
• ✅ CSRF protection (SameSite policy)
• ✅ Role-based UI and API access
• ✅ Session invalidation on logout

What Backend Must Handle

• ✅ JWT validation and signing
• ✅ Rate limiting on login
• ✅ Multi-tenant isolation
• ✅ Password hashing and security
• ✅ Token expiration

🚨 Troubleshooting

Can't login?

• Check backend is running at NEXT_PUBLIC_API_URL
• Verify backend endpoints exist: /admin/login, /admin/me
• Check credentials are correct

Session not persisting?

• Check cookie in DevTools → Cookies
• Verify auth_token is present and httpOnly
• Clear browser cache, try again

User info not showing?

• Check /api/auth/me returns user data
• Verify backend /admin/me endpoint works
• Check browser console for errors

See TESTING_GUIDE.md for troubleshooting.

🔄 What Changed

New Files (11)

• Auth utilities, types, components, API routes
• Login page and form
• Environment configuration

Updated Files (6)

• Middleware (route protection)
• Layout (providers)
• Header (logout button)
• Dependencies (zod, @hookform/resolvers)

📋 Checklist - Before Production

• Test complete login flow
• Verify all routes redirect correctly
• Check cookies are httpOnly and secure
• Enable HTTPS (set secure: true in prod)
• Configure CORS on backend for frontend domain
• Set up monitoring/error tracking
• Test with production backend URL
• Performance test (< 2 sec login time)
• Security audit
• Load test concurrent logins

🎯 Next Steps

1. Test locally using TESTING_GUIDE.md
2. Read documentation in AUTH_IMPLEMENTATION.md
3. Integrate with backend - verify endpoints work
4. Deploy to staging - test in staging environment
5. Monitor production - set up alerts and logging
