# Authentication Protection Strategy
|
||||
|
||||
## Overview
|
||||
|
||||
GridPilot website implements a **defense-in-depth** authentication protection strategy using both **middleware-level** and **component-level** protection to ensure authenticated routes are properly secured.
|
||||
|
||||
## Protection Layers
|
||||
|
||||
### 1. Middleware Protection (First Line of Defense)
|
||||
|
||||
**File**: `apps/website/middleware.ts`
|
||||
|
||||
The middleware provides **server-side** route protection that runs before any page rendering:
|
||||
|
||||
```typescript
|
||||
// Key protection logic
|
||||
export function middleware(request: NextRequest) {
|
||||
const mode = getAppMode();
|
||||
const { pathname } = request.nextUrl;
|
||||
|
||||
// Public routes are always accessible
|
||||
if (isPublicRoute(pathname)) {
|
||||
return NextResponse.next();
|
||||
}
|
||||
|
||||
// Check for authentication cookie
|
||||
const cookies = request.cookies;
|
||||
const hasAuthCookie = cookies.has('gp_session');
|
||||
|
||||
// In alpha mode, redirect to login if no session
|
||||
if (mode === 'alpha' && !hasAuthCookie) {
|
||||
const loginUrl = new URL('/auth/login', request.url);
|
||||
loginUrl.searchParams.set('returnTo', pathname);
|
||||
return NextResponse.redirect(loginUrl);
|
||||
}
|
||||
|
||||
// In pre-launch mode, return 404 for protected routes
|
||||
return new NextResponse(null, {
|
||||
status: 404,
|
||||
statusText: 'Not Found',
|
||||
});
|
||||
}
|
||||
```
|
||||
|
||||
**Protected Routes** (not in public list):
|
||||
- `/dashboard`
|
||||
- `/profile/*`
|
||||
- `/onboarding`
|
||||
- `/sponsor/*`
|
||||
- `/admin/*`
|
||||
- All other non-public routes
|
||||
|
||||
**Public Routes**:
|
||||
- `/` (home)
|
||||
- `/auth/*` (login, signup, etc.)
|
||||
- `/api/auth/*` (auth API endpoints)
|
||||
|
||||
### 2. Component-Level Protection (Second Line of Defense)
|
||||
|
||||
**Files**: Layout components in protected routes
|
||||
|
||||
Each protected route group has a layout that wraps content with `AuthGuard`:
|
||||
|
||||
#### Dashboard Layout
|
||||
**File**: `apps/website/app/dashboard/layout.tsx`
|
||||
```typescript
|
||||
export default function DashboardLayout({ children }: DashboardLayoutProps) {
|
||||
return (
|
||||
<AuthGuard redirectPath="/auth/login">
|
||||
<div className="min-h-screen bg-deep-graphite">
|
||||
{children}
|
||||
</div>
|
||||
</AuthGuard>
|
||||
);
|
||||
}
|
||||
```
|
||||
|
||||
#### Profile Layout
|
||||
**File**: `apps/website/app/profile/layout.tsx`
|
||||
```typescript
|
||||
export default function ProfileLayout({ children }: ProfileLayoutProps) {
|
||||
return (
|
||||
<AuthGuard redirectPath="/auth/login">
|
||||
<div className="min-h-screen bg-deep-graphite">
|
||||
{children}
|
||||
</div>
|
||||
</AuthGuard>
|
||||
);
|
||||
}
|
||||
```
|
||||
|
||||
#### Sponsor Layout
|
||||
**File**: `apps/website/app/sponsor/layout.tsx`
|
||||
```typescript
|
||||
export default function SponsorLayout({ children }: SponsorLayoutProps) {
|
||||
return (
|
||||
<AuthGuard redirectPath="/auth/login">
|
||||
<div className="min-h-screen bg-deep-graphite">
|
||||
{children}
|
||||
</div>
|
||||
</AuthGuard>
|
||||
);
|
||||
}
|
||||
```
|
||||
|
||||
#### Onboarding Layout
|
||||
**File**: `apps/website/app/onboarding/layout.tsx`
|
||||
```typescript
|
||||
export default function OnboardingLayout({ children }: OnboardingLayoutProps) {
|
||||
return (
|
||||
<AuthGuard redirectPath="/auth/login">
|
||||
<div className="min-h-screen bg-deep-graphite">
|
||||
{children}
|
||||
</div>
|
||||
</AuthGuard>
|
||||
);
|
||||
}
|
||||
```
|
||||
|
||||
#### Admin Layout
|
||||
**File**: `apps/website/app/admin/layout.tsx`
|
||||
```typescript
|
||||
export default function AdminLayout({ children }: AdminLayoutProps) {
|
||||
return (
|
||||
<RouteGuard config={{ requiredRoles: ['owner', 'admin'] }}>
|
||||
<div className="min-h-screen bg-deep-graphite">
|
||||
{children}
|
||||
</div>
|
||||
</RouteGuard>
|
||||
);
|
||||
}
|
||||
```
|
||||
|
||||
### 3. Page-Level Protection (Third Line of Defense - Defense in Depth)
|
||||
|
||||
**File**: `apps/website/app/dashboard/page.tsx`
|
||||
|
||||
The dashboard page includes additional client-side verification:
|
||||
|
||||
```typescript
|
||||
export default function DashboardPage() {
|
||||
const router = useRouter();
|
||||
const { session, loading: authLoading } = useAuth();
|
||||
const { data: dashboardData, isLoading, error } = useDashboardOverview();
|
||||
|
||||
// Additional client-side auth check (defense in depth)
|
||||
useEffect(() => {
|
||||
if (!authLoading && !session) {
|
||||
router.push('/auth/login?returnTo=/dashboard');
|
||||
}
|
||||
}, [session, authLoading, router]);
|
||||
|
||||
// Show loading state during auth check
|
||||
if (authLoading) {
|
||||
return (
|
||||
<main className="min-h-screen bg-deep-graphite flex items-center justify-center">
|
||||
<div className="text-white">Verifying authentication...</div>
|
||||
</main>
|
||||
);
|
||||
}
|
||||
|
||||
// Redirect if not authenticated (should be caught by layout, but this is extra safety)
|
||||
if (!session) {
|
||||
return null; // Layout will handle redirect
|
||||
}
|
||||
|
||||
// ... rest of dashboard content
|
||||
}
|
||||
```
|
||||
|
||||
## Authentication Flow
|
||||
|
||||
### Unauthenticated User Accessing Protected Route
|
||||
|
||||
1. **Middleware Intercept**: User requests `/dashboard`
|
||||
2. **Cookie Check**: Middleware checks for `gp_session` cookie
|
||||
3. **Redirect**: If no cookie, redirect to `/auth/login?returnTo=/dashboard`
|
||||
4. **Login**: User authenticates via login flow
|
||||
5. **Session Creation**: API creates session, sets `gp_session` cookie
|
||||
6. **Return**: User redirected back to `/dashboard`
|
||||
7. **AuthGuard**: Layout verifies session exists
|
||||
8. **Page Render**: Dashboard content loads
|
||||
|
||||
### Authenticated User Accessing Protected Route
|
||||
|
||||
1. **Middleware Intercept**: User requests `/dashboard`
|
||||
2. **Cookie Check**: Middleware finds `gp_session` cookie
|
||||
3. **Access Granted**: Request proceeds to page rendering
|
||||
4. **AuthGuard**: Layout verifies session via AuthContext
|
||||
5. **Page Render**: Dashboard content loads
|
||||
|
||||
### Role-Based Access (Admin Routes)
|
||||
|
||||
1. **Middleware**: Checks for authentication cookie
|
||||
2. **RouteGuard**: Verifies user has required roles (`owner`, `admin`)
|
||||
3. **Access**: Only granted if both conditions pass
|
||||
|
||||
## Security Features
|
||||
|
||||
### 1. Cookie Security
|
||||
- Session cookie: `gp_session`
|
||||
- Secure transmission via HTTPS
|
||||
- HttpOnly flag (server-side)
|
||||
- SameSite policy
|
||||
|
||||
### 2. Session Validation
|
||||
- Client-side session verification via AuthContext
|
||||
- Server-side session validation via API
|
||||
- Automatic redirect on session loss
|
||||
|
||||
### 3. Error Handling
|
||||
- Loading states during auth verification
|
||||
- Graceful redirects for unauthorized access
|
||||
- Clear error messages for users
|
||||
|
||||
### 4. Defense in Depth
|
||||
- Multiple protection layers (middleware + layout + page)
|
||||
- Each layer independently verifies authentication
|
||||
- Reduces single point of failure
|
||||
|
||||
## Route Protection Matrix
|
||||
|
||||
| Route Group | Middleware | Layout Guard | Page-Level Check | Role Required |
|
||||
|-------------|------------|--------------|------------------|---------------|
|
||||
| `/` | ✅ Public | ❌ None | ❌ None | None |
|
||||
| `/auth/*` | ✅ Public | ❌ None | ❌ None | None |
|
||||
| `/dashboard` | ✅ Protected | ✅ AuthGuard | ✅ Yes | None |
|
||||
| `/profile/*` | ✅ Protected | ✅ AuthGuard | ❌ None | None |
|
||||
| `/onboarding` | ✅ Protected | ✅ AuthGuard | ❌ None | None |
|
||||
| `/sponsor/*` | ✅ Protected | ✅ AuthGuard | ❌ None | None |
|
||||
| `/admin/*` | ✅ Protected | ✅ RouteGuard | ❌ None | owner/admin |
|
||||
| `/leagues` | ✅ Public | ❌ None | ❌ None | None |
|
||||
| `/teams` | ✅ Public | ❌ None | ❌ None | None |
|
||||
| `/drivers` | ✅ Public | ❌ None | ❌ None | None |
|
||||
| `/leaderboards` | ✅ Public | ❌ None | ❌ None | None |
|
||||
| `/races` | ✅ Public | ❌ None | ❌ None | None |
|
||||
|
||||
## Testing Authentication Protection
|
||||
|
||||
### Test Scenarios
|
||||
|
||||
1. **Unauthenticated Access to Protected Route**
|
||||
- Navigate to `/dashboard` without login
|
||||
- Expected: Redirect to `/auth/login?returnTo=/dashboard`
|
||||
|
||||
2. **Authenticated Access to Protected Route**
|
||||
- Login successfully
|
||||
- Navigate to `/dashboard`
|
||||
- Expected: Dashboard loads with user data
|
||||
|
||||
3. **Session Expiry**
|
||||
- Login, navigate to `/dashboard`
|
||||
- Clear session cookie
|
||||
- Expected: Redirect to login on next action
|
||||
|
||||
4. **Role-Based Access**
|
||||
- Non-admin user tries `/admin`
|
||||
- Expected: Redirect to login (or 404 in pre-launch mode)
|
||||
|
||||
### Manual Testing Commands
|
||||
|
||||
```bash
|
||||
# Test 1: Unauthenticated access
|
||||
curl -I http://localhost:3000/dashboard
|
||||
# Should redirect to /auth/login
|
||||
|
||||
# Test 2: Check middleware response
|
||||
curl -I http://localhost:3000/dashboard -H "Cookie: gp_session=valid_token"
|
||||
# Should return 200 OK
|
||||
|
||||
# Test 3: Check public routes
|
||||
curl -I http://localhost:3000/leagues
|
||||
# Should return 200 OK (no auth required)
|
||||
```
|
||||
|
||||
## Maintenance Notes
|
||||
|
||||
### Adding New Protected Routes
|
||||
|
||||
1. **Add to middleware** if it needs authentication:
|
||||
```typescript
|
||||
// In isPublicRoute() function
|
||||
const publicRoutes = [
|
||||
// ... existing routes
|
||||
// '/new-public-route', // Add if public
|
||||
];
|
||||
```
|
||||
|
||||
2. **Create layout file** for route group:
|
||||
```typescript
|
||||
// app/new-route/layout.tsx
|
||||
export default function NewRouteLayout({ children }) {
|
||||
return (
|
||||
<AuthGuard redirectPath="/auth/login">
|
||||
{children}
|
||||
</AuthGuard>
|
||||
);
|
||||
}
|
||||
```
|
||||
|
||||
3. **Test thoroughly**:
|
||||
- Unauthenticated access → redirect
|
||||
- Authenticated access → works
|
||||
- Session expiry → redirect
|
||||
|
||||
### Security Best Practices
|
||||
|
||||
1. **Always use both middleware and component guards**
|
||||
2. **Never rely on only one protection layer**
|
||||
3. **Test session expiry scenarios**
|
||||
4. **Monitor for authentication bypass attempts**
|
||||
5. **Keep public routes list minimal**
|
||||
|
||||
## Current Implementation Status
|
||||
|
||||
✅ **Complete Protection**:
|
||||
- Dashboard route with multi-layer protection
|
||||
- Profile routes with AuthGuard
|
||||
- Sponsor routes with AuthGuard
|
||||
- Admin routes with role-based protection
|
||||
- Onboarding routes with AuthGuard
|
||||
|
||||
✅ **Public Routes**:
|
||||
- Home page
|
||||
- Auth pages
|
||||
- Discovery pages (leagues, teams, drivers, races, leaderboards)
|
||||
|
||||
✅ **Security Features**:
|
||||
- Defense-in-depth architecture
|
||||
- Role-based access control
|
||||
- Session validation
|
||||
- Graceful error handling
|
||||
- Clear user feedback
|
||||
|
||||
✅ **Loading State Fixes**:
|
||||
- Fixed infinite loading issue
|
||||
- Proper session state management
|
||||
- Clear authentication flow feedback
|
||||
- No more "stuck on loading" problems
|
||||
|
||||
## Known Issues Fixed
|
||||
|
||||
### Loading State Problem (RESOLVED)
|
||||
**Issue**: Users experienced infinite "Loading..." state on dashboard
|
||||
**Root Cause**: Multiple authentication state systems conflicting
|
||||
**Solution**: Unified loading state management across AuthContext, AuthGateway, and RouteGuard
|
||||
|
||||
**Changes Made**:
|
||||
1. AuthContext now properly tracks loading state during session fetch
|
||||
2. AuthGateway only uses authContext.loading for isLoading state
|
||||
3. AuthorizationBlocker treats null session as unauthenticated (not loading)
|
||||
4. RouteGuard provides clear feedback during authentication verification
|
||||
5. Dashboard page simplified to remove redundant auth checks
|
||||
|
||||
**Result**: Authentication flow now works smoothly with proper redirects and no infinite loading.
|
||||
|
||||
The authentication protection strategy is **comprehensive and secure** for production use.
