Implementation Checklist - CSRF Token and Auth Control

• CSRF token injection into POST requests
• CSRF token injection into PUT requests
• CSRF token injection into PATCH requests
• CSRF token injection into DELETE requests
• No CSRF token in GET requests
• CSRF token refresh on each response
• Cookie set with SameSite=Strict

Auth Token Protection

• Auth token storage in localStorage
• Auth token injection into all requests
• Auth token sent via Authorization: Bearer header
• Session check on app initialization
• Session check via /auth/me endpoint
• 401 error handling (logout and redirect)
• 403 error handling (redirect to unauthorized)
• Auth token cleared on logout
• Auth token cleared on 401 response

Login Page

• Email input field
• Password input field
• Submit button
• Error display
• Loading state
• CSRF token handling
• Auth token storage
• Redirect to dashboard on success
• Redirect to login if already authenticated

Unauthorized Page

• Access denied message
• Go back button
• Go home button
• Proper styling
• Route integration

Routing

• Protected routes require authentication
• Redirect to login if not authenticated
• Redirect to unauthorized on 403
• Loading state during auth check

Error Handling

• 401 Unauthorized handling
• 403 Forbidden handling
• Network error handling
• Invalid token handling
• Expired token handling

Type Safety

• No any types in axios.ts
• No any types in auth.ts
• No any types in login.tsx
• All functions properly typed
• All responses properly typed
• All errors properly typed

Code Quality

• 0 diagnostics in axios.ts
• 0 diagnostics in auth.ts
• 0 diagnostics in login.tsx
• 0 diagnostics in App.tsx
• Proper error handling
• Proper logging (if needed)
• Proper comments

• CSRF_AUTH_IMPLEMENTATION_SUMMARY.md created
• TASK_5_COMPLETION_SUMMARY.md created
• IMPLEMENTATION_VERIFICATION.md created
• QUICK_START_AUTH.md created
• TASK_5_FINAL_SUMMARY.md created

⏳ Backend Implementation Required

Auth Endpoints

• POST /api/auth/login

  • Accept email and password
  • Return user, token, and csrf_token
  • Validate credentials
  • Generate JWT token
  • Generate CSRF token

• GET /api/auth/me

  • Require Authorization header
  • Validate JWT token
  • Return current user
  • Return CSRF token (optional)
  • Return 401 if invalid token

• POST /api/auth/logout

  • Require Authorization header
  • Require X-CSRF-Token header
  • Validate both tokens
  • Invalidate token
  • Return 200 OK

CSRF Token Validation

• Check X-CSRF-Token header in all non-GET requests
• Compare with token stored on backend
• Return 403 if invalid
• Return 403 if missing
• Refresh token on each response

Auth Token Validation

• Check Authorization header in all requests
• Validate JWT signature
• Validate token expiration
• Return 401 if invalid
• Return 401 if expired
• Return 401 if missing (for protected endpoints)

Response Headers

• Include x-csrf-token in all responses
• Include user data in /auth/me response
• Include token in /auth/login response
• Include csrf_token in /auth/login response

🧪 Testing Checklist

CSRF Token Testing

• Make POST request and verify X-CSRF-Token header
• Make PUT request and verify X-CSRF-Token header
• Make PATCH request and verify X-CSRF-Token header
• Make DELETE request and verify X-CSRF-Token header
• Make GET request and verify no X-CSRF-Token header
• Verify CSRF token stored in XSRF-TOKEN cookie
• Verify CSRF token refreshed on each response
• Verify CSRF token sent with correct value

Auth Token Testing

• Login with valid credentials
• Verify auth token stored in localStorage
• Verify Authorization header in requests
• Verify token sent with correct format (Bearer )
• Logout and verify token cleared
• Verify redirect to login on 401
• Verify redirect to unauthorized on 403
• Verify session check on app initialization

Error Handling Testing

• Test 401 response (logout and redirect)
• Test 403 response (redirect to unauthorized)
• Test network error (graceful handling)
• Test invalid token (logout and redirect)
• Test expired token (logout and redirect)
• Test missing token (redirect to login)

Integration Testing

• Test login flow end-to-end
• Test CSRF token flow end-to-end
• Test auth token flow end-to-end
• Test session persistence after page reload
• Test logout flow end-to-end
• Test protected route access
• Test unauthorized route access
