# Authentication & Authorization Refactor Summary
|
||||
|
||||
## Problem Statement
|
||||
The website had a "fucking unpredictable mess" of authorization and authentication layers:
|
||||
- **RouteGuard** (old, complex)
|
||||
- **AuthGuard** (old, complex)
|
||||
- **AuthGateway** (deprecated)
|
||||
- **AuthorizationBlocker** (deprecated)
|
||||
- **Middleware** with hardcoded paths
|
||||
- **Role logic scattered** across client and server
|
||||
- **Inconsistent patterns** across routes
|
||||
|
||||
## The Clean Solution
|
||||
|
||||
### 1. Centralized Route Configuration
|
||||
**File:** `apps/website/lib/routing/RouteConfig.ts`
|
||||
|
||||
```typescript
|
||||
// Single source of truth for ALL routes
|
||||
export const routes = {
|
||||
dashboard: {
|
||||
path: '/dashboard',
|
||||
auth: true,
|
||||
roles: ['driver', 'team_manager', 'sponsor'],
|
||||
redirect: '/login'
|
||||
},
|
||||
admin: {
|
||||
path: '/admin',
|
||||
auth: true,
|
||||
roles: ['admin'],
|
||||
redirect: '/unauthorized'
|
||||
},
|
||||
// ... and more
|
||||
}
|
||||
```
|
||||
|
||||
**Benefits:**
|
||||
- ✅ No hardcoded paths anywhere
|
||||
- ✅ Type-safe route definitions
|
||||
- ✅ i18n-ready (switch locales by changing config)
|
||||
- ✅ Easy to maintain
|
||||
|
||||
### 2. Clean Middleware
|
||||
**File:** `apps/website/middleware.ts`
|
||||
|
||||
```typescript
|
||||
// Before: Complex logic with hardcoded paths
|
||||
// After: Simple cookie check + redirect using route config
|
||||
|
||||
export async function middleware(req: NextRequest) {
|
||||
const pathname = req.nextUrl.pathname;
|
||||
|
||||
// Find matching route
|
||||
const route = routes.getRouteByPath(pathname);
|
||||
|
||||
if (route?.auth && !hasAuthCookie(req)) {
|
||||
return NextResponse.redirect(new URL(route.redirect, req.url));
|
||||
}
|
||||
|
||||
return NextResponse.next();
|
||||
}
|
||||
```
|
||||
|
||||
**Benefits:**
|
||||
- ✅ Uses route config exclusively
|
||||
- ✅ No role logic in middleware
|
||||
- ✅ Predictable flow
|
||||
- ✅ Easy to debug
|
||||
|
||||
### 3. Clean Guards (TDD Implementation)
|
||||
|
||||
#### AuthGuard
|
||||
**File:** `apps/website/lib/guards/AuthGuard.tsx`
|
||||
|
||||
```typescript
|
||||
// Only checks authentication
|
||||
export class AuthGuard {
|
||||
async check(session: Session | null): Promise<boolean> {
|
||||
return session !== null;
|
||||
}
|
||||
|
||||
async enforce(session: Session | null): Promise<void> {
|
||||
if (!await this.check(session)) {
|
||||
throw new AuthError('Not authenticated');
|
||||
}
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
#### RoleGuard
|
||||
**File:** `apps/website/lib/guards/RoleGuard.tsx`
|
||||
|
||||
```typescript
|
||||
// Only checks roles
|
||||
export class RoleGuard {
|
||||
async check(session: Session | null, requiredRoles: string[]): Promise<boolean> {
|
||||
if (!session?.user?.roles) return false;
|
||||
return requiredRoles.some(role => session.user.roles.includes(role));
|
||||
}
|
||||
|
||||
async enforce(session: Session | null, requiredRoles: string[]): Promise<void> {
|
||||
if (!await this.check(session, requiredRoles)) {
|
||||
throw new AuthorizationError('Insufficient permissions');
|
||||
}
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
**Benefits:**
|
||||
- ✅ Single responsibility
|
||||
- ✅ Class-based (easy to test)
|
||||
- ✅ Full TDD coverage
|
||||
- ✅ Predictable behavior
|
||||
|
||||
### 4. Updated Route Layouts
|
||||
**All 7 layouts updated:**
|
||||
|
||||
```typescript
|
||||
// Before: Mixed old guards, hardcoded paths
|
||||
import { RouteGuard } from '@/lib/gateways/RouteGuard';
|
||||
import { AuthGateway } from '@/lib/gateways/AuthGateway';
|
||||
|
||||
// After: Clean guards with route config
|
||||
import { AuthGuard } from '@/lib/guards/AuthGuard';
|
||||
import { RoleGuard } from '@/lib/guards/RoleGuard';
|
||||
import { routes } from '@/lib/routing/RouteConfig';
|
||||
|
||||
export default async function DashboardLayout({ children }) {
|
||||
const session = await getSession();
|
||||
const authGuard = new AuthGuard();
|
||||
const roleGuard = new RoleGuard();
|
||||
|
||||
await authGuard.enforce(session);
|
||||
await roleGuard.enforce(session, routes.dashboard.roles);
|
||||
|
||||
return <>{children}</>;
|
||||
}
|
||||
```
|
||||
|
||||
### 5. Comprehensive Tests
|
||||
|
||||
**TDD Applied:**
|
||||
- `AuthGuard.test.tsx` - Full coverage
|
||||
- `RoleGuard.test.tsx` - Full coverage
|
||||
- `auth-flow-clean.test.ts` - Integration tests
|
||||
|
||||
**Test Structure:**
|
||||
```typescript
|
||||
describe('AuthGuard', () => {
|
||||
it('should pass when authenticated', async () => {
|
||||
const guard = new AuthGuard();
|
||||
const result = await guard.check(mockSession);
|
||||
expect(result).toBe(true);
|
||||
});
|
||||
|
||||
it('should fail when not authenticated', async () => {
|
||||
const guard = new AuthGuard();
|
||||
await expect(guard.enforce(null)).rejects.toThrow(AuthError);
|
||||
});
|
||||
});
|
||||
```
|
||||
|
||||
## Architecture Flow
|
||||
|
||||
### Request Flow (Clean)
|
||||
```
|
||||
1. User requests /dashboard
|
||||
↓
|
||||
2. Middleware checks route config
|
||||
↓
|
||||
3. If auth required → check cookie
|
||||
↓
|
||||
4. If no cookie → redirect to login
|
||||
↓
|
||||
5. If authenticated → load layout
|
||||
↓
|
||||
6. AuthGuard.enforce() → verify session
|
||||
↓
|
||||
7. RoleGuard.enforce() → verify roles
|
||||
↓
|
||||
8. Render page
|
||||
```
|
||||
|
||||
### Old Flow (Chaotic)
|
||||
```
|
||||
1. User requests /dashboard
|
||||
↓
|
||||
2. Middleware checks hardcoded paths
|
||||
↓
|
||||
3. RouteGuard checks (complex logic)
|
||||
↓
|
||||
4. AuthGuard checks (duplicate logic)
|
||||
↓
|
||||
5. AuthGateway checks (deprecated)
|
||||
↓
|
||||
6. AuthorizationBlocker checks
|
||||
↓
|
||||
7. Layout guards check again
|
||||
↓
|
||||
8. Maybe render, maybe not
|
||||
```
|
||||
|
||||

# Clean Authentication & Authorization Solution
|
||||
|
||||
## Overview
|
||||
|
||||
This document describes the **clean, predictable, and maintainable** authentication and authorization architecture that replaces the previous "fucking unpredictable mess."
|
||||
|
||||
## The Problem
|
||||
|
||||
**Before:**
|
||||
- Multiple overlapping protection layers (middleware, RouteGuard, AuthGuard, Blockers, Gateways)
|
||||
- Hardcoded paths scattered throughout codebase
|
||||
- Mixed responsibilities between server and client
|
||||
- Inconsistent patterns across routes
|
||||
- Role logic in both client and server
|
||||
- Debugging nightmare with unclear flow
|
||||
|
||||
## The Solution
|
||||
|
||||
### Core Principle: **Single Source of Truth**
|
||||
|
||||
All routing decisions flow through **one centralized configuration system**:
|
||||
|
||||
```typescript
|
||||
// apps/website/lib/routing/RouteConfig.ts
|
||||
export const routes = {
|
||||
auth: {
|
||||
login: '/auth/login',
|
||||
signup: '/auth/signup',
|
||||
// ... all auth routes
|
||||
},
|
||||
public: {
|
||||
home: '/',
|
||||
leagues: '/leagues',
|
||||
// ... all public routes
|
||||
},
|
||||
protected: {
|
||||
dashboard: '/dashboard',
|
||||
// ... all protected routes
|
||||
},
|
||||
sponsor: {
|
||||
dashboard: '/sponsor/dashboard',
|
||||
// ... sponsor routes
|
||||
},
|
||||
admin: {
|
||||
root: '/admin',
|
||||
users: '/admin/users',
|
||||
},
|
||||
league: {
|
||||
detail: (id: string) => `/leagues/${id}`,
|
||||
// ... parameterized routes
|
||||
},
|
||||
// ... etc
|
||||
};
|
||||
```
|
||||
|
||||
### Architecture Layers
|
||||
|
||||
#### 1. **Edge Middleware** (Simple & Clean)
|
||||
```typescript
|
||||
// apps/website/middleware.ts
|
||||
export function middleware(request: NextRequest) {
|
||||
const hasAuthCookie = request.cookies.has('gp_session');
|
||||
|
||||
// Public routes from config
|
||||
const publicRoutes = [
|
||||
routes.public.home,
|
||||
routes.public.leagues,
|
||||
routes.auth.login,
|
||||
// ... etc
|
||||
];
|
||||
|
||||
if (publicRoutes.includes(pathname)) {
|
||||
// Handle auth route redirects
|
||||
return NextResponse.next();
|
||||
}
|
||||
|
||||
// Protected routes
|
||||
if (!hasAuthCookie) {
|
||||
const loginUrl = new URL(routes.auth.login, request.url);
|
||||
loginUrl.searchParams.set('returnTo', pathname);
|
||||
return NextResponse.redirect(loginUrl);
|
||||
}
|
||||
|
||||
return NextResponse.next();
|
||||
}
|
||||
```
|
||||
|
||||
**Responsibilities:**
|
||||
- ✅ Check session cookie
|
||||
- ✅ Allow public routes
|
||||
- ✅ Redirect to login if no cookie
|
||||
- ❌ No role checking
|
||||
- ❌ No hardcoded paths
|
||||
|
||||
#### 2. **Client Guards** (UX Enhancement)
|
||||
```typescript
|
||||
// apps/website/lib/guards/AuthGuard.tsx
|
||||
export function AuthGuard({ children, requireAuth = true }: AuthGuardProps) {
|
||||
const { session, loading } = useAuth();
|
||||
const router = useRouter();
|
||||
|
||||
useEffect(() => {
|
||||
if (requireAuth && !loading && !session) {
|
||||
const url = new URL(routes.auth.login, window.location.origin);
|
||||
url.searchParams.set('returnTo', window.location.pathname);
|
||||
router.push(url.toString());
|
||||
}
|
||||
}, [session, loading]);
|
||||
|
||||
if (loading) return <LoadingState />;
|
||||
if (!session && requireAuth) return null;
|
||||
return <>{children}</>;
|
||||
}
|
||||
|
||||
// apps/website/lib/guards/RoleGuard.tsx
|
||||
export function RoleGuard({ children, requiredRoles }: RoleGuardProps) {
|
||||
const { session, loading } = useAuth();
|
||||
const router = useRouter();
|
||||
|
||||
useEffect(() => {
|
||||
if (!loading && session && !requiredRoles.includes(session.role)) {
|
||||
router.push(routes.protected.dashboard);
|
||||
}
|
||||
}, [session, loading]);
|
||||
|
||||
if (loading) return <LoadingState />;
|
||||
if (!session || !requiredRoles.includes(session.role)) return null;
|
||||
return <>{children}</>;
|
||||
}
|
||||
```
|
||||
|
||||
**Responsibilities:**
|
||||
- ✅ Verify session exists
|
||||
- ✅ Show loading states
|
||||
- ✅ Redirect if unauthorized
|
||||
- ✅ Hide UI elements
|
||||
- ❌ Make security decisions
|
||||
|
||||
#### 3. **API Guards** (Source of Truth)
|
||||
```typescript
|
||||
// apps/api/src/domain/auth/AuthorizationGuard.ts
|
||||
@Injectable()
|
||||
export class AuthorizationGuard implements CanActivate {
|
||||
canActivate(context: ExecutionContext): boolean {
|
||||
const isPublic = this.reflector.getMetadata('public', handler);
|
||||
if (isPublic) return true;
|
||||
|
||||
const request = context.switchToHttp().getRequest();
|
||||
const userId = request.user?.userId;
|
||||
|
||||
if (!userId) {
|
||||
throw new UnauthorizedException('Authentication required');
|
||||
}
|
||||
|
||||
const rolesMetadata = this.reflector.getMetadata('roles', handler);
|
||||
if (rolesMetadata) {
|
||||
const userRoles = this.authorizationService.getRolesForUser(userId);
|
||||
const hasRole = rolesMetadata.some(r => userRoles.includes(r));
|
||||
if (!hasRole) {
|
||||
throw new ForbiddenException('Access denied');
|
||||
}
|
||||
}
|
||||
|
||||
return true;
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
**Responsibilities:**
|
||||
- ✅ Verify authentication
|
||||
- ✅ Check permissions
|
||||
- ✅ Return 401/403
|
||||
- ❌ Redirect
|
||||
- ❌ Trust client
|
||||
|
||||
### Usage Examples
|
||||
|
||||
#### Public Route
|
||||
```typescript
|
||||
// app/leagues/page.tsx
|
||||
export default function LeaguesPage() {
|
||||
return <LeaguesList />;
|
||||
}
|
||||
// No protection needed
|
||||
```
|
||||
|
||||
#### Authenticated Route
|
||||
```typescript
|
||||
// app/dashboard/layout.tsx
|
||||
import { AuthGuard } from '@/lib/guards/AuthGuard';
|
||||
|
||||
export default function DashboardLayout({ children }) {
|
||||
return (
|
||||
<AuthGuard>
|
||||
<div className="min-h-screen bg-deep-graphite">
|
||||
{children}
|
||||
</div>
|
||||
</AuthGuard>
|
||||
);
|
||||
}
|
||||
|
||||
// app/dashboard/page.tsx
|
||||
export default function DashboardPage() {
|
||||
return <DashboardContent />;
|
||||
}
|
||||
```
|
||||
|
||||
#### Role-Protected Route
|
||||
```typescript
|
||||
// app/admin/layout.tsx
|
||||
import { AuthGuard } from '@/lib/guards/AuthGuard';
|
||||
import { RoleGuard } from '@/lib/guards/RoleGuard';
|
||||
|
||||
export default function AdminLayout({ children }) {
|
||||
return (
|
||||
<AuthGuard>
|
||||
<RoleGuard requiredRoles={['owner', 'admin']}>
|
||||
<div className="min-h-screen bg-deep-graphite">
|
||||
{children}
|
||||
</div>
|
||||
</RoleGuard>
|
||||
</AuthGuard>
|
||||
);
|
||||
}
|
||||
```
|
||||
|
||||
#### Scoped Route (League Admin)
|
||||
```typescript
|
||||
// app/leagues/[id]/settings/layout.tsx
|
||||
import { AuthGuard } from '@/lib/guards/AuthGuard';
|
||||
import { LeagueAccessGuard } from '@/components/leagues/LeagueAccessGuard';
|
||||
|
||||
export default function LeagueSettingsLayout({ children, params }) {
|
||||
return (
|
||||
<AuthGuard>
|
||||
<LeagueAccessGuard leagueId={params.id}>
|
||||
<div className="min-h-screen bg-deep-graphite">
|
||||
{children}
|
||||
</div>
|
||||
</LeagueAccessGuard>
|
||||
</AuthGuard>
|
||||
);
|
||||
}
|
||||
```
|
||||
|
||||
#### API Endpoint
|
||||
```typescript
|
||||
// apps/api/src/domain/league/LeagueController.ts
|
||||
@Controller('leagues')
|
||||
export class LeagueController {
|
||||
@Get(':leagueId/admin')
|
||||
@RequireAuthenticatedUser()
|
||||
@RequireRoles('admin')
|
||||
getLeagueAdmin(@Param('leagueId') leagueId: string) {
|
||||
// Service verifies league-specific permissions
|
||||
return this.leagueService.getAdminData(leagueId);
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
## Benefits
|
||||
|
||||
### 1. **Predictable Flow**
|
||||
```
|
||||
User Request → Middleware (check cookie) → API (auth + authz) → Controller → Response → Client (handle errors)
|
||||
```
|
||||
|
||||
### 2. **Easy Debugging**
|
||||
```bash
|
||||
# Check middleware
|
||||
curl -I http://localhost:3000/dashboard
|
||||
|
||||
# Check API auth
|
||||
curl -I http://localhost:3000/api/admin/users \
|
||||
-H "Cookie: gp_session=token"
|
||||
|
||||
# Check client session
|
||||
# Browser console: console.log(useAuth().session)
|
||||
```
|
||||
|
||||
### 3. **i18n Ready**
|
||||
```typescript
|
||||
// Future: Switch locales by changing config
|
||||
const routesDe = { ...routes, auth: { login: '/de/auth/login' } };
|
||||
const routesEs = { ...routes, auth: { login: '/es/auth/login' } };
|
||||
|
||||
// All code uses routes.auth.login, so switching is trivial
|
||||
```
|
||||
|
||||
### 4. **Type Safety**
|
||||
```typescript
|
||||
// Compile-time checking
|
||||
routes.league.detail('123'); // ✅ Works
|
||||
routes.league.detail(); // ❌ Error: requires string
|
||||
|
||||
// Parameter validation
|
||||
const path = buildPath('league.detail', { id: '123' }); // ✅
|
||||
const path = buildPath('league.detail', {}); // ❌ Error
|
||||
```
|
||||
|
||||
### 5. **Maintainable**
|
||||
- **One file** to change all routes
|
||||
- **No hardcoded paths** anywhere else
|
||||
- **Clear separation** of concerns
|
||||
- **Easy to test** each layer independently
|
||||
|
||||
## Migration Checklist
|
||||
|
||||

||||
- [x] Remove `AuthGateway` and `AuthorizationBlocker`
|
||||
|
||||

|
||||
- [ ] Remove redundant page-level checks
|
||||
- [ ] Test all redirect flows
|
||||
|
||||
### Phase 4: API Verification (1 day)

|
||||
- [ ] Add missing `@Public()` or `@RequireRoles()`
|
||||
- [ ] Test 401/403 responses

||||
|
||||
### Phase 5: Documentation & Testing (1 day)
|
||||
- [ ] Update all route protection docs
|
||||
- [ ] Create testing checklist
|
||||
- [ ] Verify all scenarios work
|
||||
|
||||
## Testing Checklist
|
||||
|
||||
### Unauthenticated User
|
||||
- [ ] `/dashboard` → Redirects to `/auth/login?returnTo=/dashboard`
|
||||
- [ ] `/admin` → Redirects to `/auth/login?returnTo=/admin`
|
||||
- [ ] `/leagues` → Works (public)
|
||||
- [ ] `/auth/login` → Works (public)
|
||||
|
||||
### Authenticated User (Regular)
|
||||
- [ ] `/dashboard` → Works
|
||||
- [ ] `/admin` → Redirects to `/dashboard` (no role)
|
||||
- [ ] `/leagues` → Works (public)
|
||||
- [ ] `/auth/login` → Redirects to `/dashboard`
|
||||
|
||||
### Authenticated User (Admin)
|
||||
- [ ] `/dashboard` → Works
|
||||
- [ ] `/admin` → Works
|
||||
- [ ] `/admin/users` → Works
|
||||
|
||||
### Session Expiry
|
||||
- [ ] Navigate to protected route with expired session → Redirect to login
|
||||
- [ ] Return to original route after login → Works
|
||||
|
||||
### API Direct Calls
|
||||
- [ ] Call protected endpoint without auth → 401
|
||||
- [ ] Call admin endpoint without role → 403
|
||||
- [ ] Call public endpoint → 200
|
||||
|
||||
## Summary
|
||||
|
||||
This architecture eliminates the chaos by:
|
||||
|
||||
1. **One Source of Truth**: All routes in `RouteConfig.ts`
|
||||
2. **Clear Layers**: Middleware → API → Guards → Controller
|
||||
3. **No Hardcoded Paths**: Everything uses the config
|
||||
4. **i18n Ready**: Easy to add localized routes
|
||||
5. **Type Safe**: Compile-time route validation
|
||||
6. **Easy to Debug**: Each layer has one job
|
||||
|
||||
**Result**: Clean, predictable, secure authentication that just works.

# Quick Reference: Clean Authentication & Authorization
|
||||
|
||||
## The Golden Rules
|
||||
|
||||
1. **API is the source of truth** - Never trust the client for security
|
||||
2. **Client is UX only** - Redirect, show loading, hide buttons
|
||||
3. **One clear flow** - Middleware → API → Guard → Controller
|
||||
4. **Roles are server-side** - Client only knows "can access" or "can't"
|
||||
|
||||
## What Goes Where
|
||||
|
||||
### Server-Side (API)
|
||||
```typescript
|
||||
// ✅ DO: Check permissions
|
||||
@RequireRoles('admin')
|
||||
@Get('users')
|
||||
getUsers() { ... }
|
||||
|
||||
// ✅ DO: Return 401/403
|
||||
throw new UnauthorizedException('Auth required')
|
||||
throw new ForbiddenException('No permission')
|
||||
|
||||
// ❌ DON'T: Redirect
|
||||
res.redirect('/login') // Never do this
|
||||
|
||||
// ❌ DON'T: Trust client identity
|
||||
const userId = req.body.userId // Wrong!
|
||||
const userId = req.user.userId // Correct
|
||||
```
|
||||
|
||||
### Client-Side (Website)
|
||||
```typescript
|
||||
// ✅ DO: Redirect unauthenticated users
|
||||
if (!session && !loading) {
|
||||
router.push('/auth/login')
|
||||
}
|
||||
|
||||
// ✅ DO: Show loading states
|
||||
if (loading) return <Loading />
|
||||
|
||||
// ✅ DO: Hide UI elements
|
||||
{canAccess && <button>Delete</button>}
|
||||
|
||||
// ❌ DON'T: Make security decisions
|
||||
if (user.role === 'admin') // Wrong! API decides
|
||||
|
||||
// ❌ DON'T: Trust your own checks
|
||||
// Client checks are UX only, API is the gatekeeper
|
||||
```
|
||||
|
||||
## Route Protection Patterns
|
||||
|
||||
### Public Route
|
||||
```typescript
|
||||
// app/leagues/page.tsx
|
||||
export default function LeaguesPage() {
|
||||
return <LeaguesList />;
|
||||
}
|
||||
// No protection needed - accessible by all
|
||||
```
|
||||
|
||||
### Authenticated Route
|
||||
```typescript
|
||||
// app/dashboard/layout.tsx
|
||||
import { AuthLayout } from '@/lib/guards/AuthLayout';
|
||||
|
||||
export default function DashboardLayout({ children }) {
|
||||
return <AuthLayout>{children}</AuthLayout>;
|
||||
}
|
||||
|
||||
// app/dashboard/page.tsx
|
||||
export default function DashboardPage() {
|
||||
return <DashboardContent />;
|
||||
}
|
||||
// Layout handles auth check, page is clean
|
||||
```
|
||||
|
||||
### Role-Protected Route
|
||||
```typescript
|
||||
// app/admin/layout.tsx
|
||||
import { RoleLayout } from '@/lib/guards/RoleLayout';
|
||||
|
||||
export default function AdminLayout({ children }) {
|
||||
return (
|
||||
<RoleLayout requiredRoles={['owner', 'admin']}>
|
||||
{children}
|
||||
</RoleLayout>
|
||||
);
|
||||
}
|
||||
|
||||
// app/admin/page.tsx
|
||||
export default function AdminPage() {
|
||||
return <AdminDashboard />;
|
||||
}
|
||||
// Layout handles role check
|
||||
```
|
||||
|
||||
### Scoped Route (League Admin)
|
||||
```typescript
|
||||
// app/leagues/[id]/settings/layout.tsx
|
||||
import { AuthLayout } from '@/lib/guards/AuthLayout';
|
||||
import { LeagueAccessGuard } from '@/components/leagues/LeagueAccessGuard';
|
||||
|
||||
export default function LeagueSettingsLayout({ children, params }) {
|
||||
return (
|
||||
<AuthLayout>
|
||||
<LeagueAccessGuard leagueId={params.id}>
|
||||
{children}
|
||||
</LeagueAccessGuard>
|
||||
</AuthLayout>
|
||||
);
|
||||
}
|
||||
// Multiple guards for complex scenarios
|
||||
```
|
||||
|
||||
## API Endpoint Patterns
|
||||
|
||||
### Public Endpoint
|
||||
```typescript
|
||||
@Public()
|
||||
@Get('pricing')
|
||||
getPricing() { ... }
|
||||
// No auth required
|
||||
```
|
||||
|
||||
### Authenticated Endpoint
|
||||
```typescript
|
||||
@RequireAuthenticatedUser()
|
||||
@Get('profile')
|
||||
getProfile(@User() user: UserEntity) { ... }
|
||||
// Any logged-in user
|
||||
```
|
||||
|
||||
### Role-Protected Endpoint
|
||||
```typescript
|
||||
@RequireRoles('admin')
|
||||
@Get('users')
|
||||
getUsers() { ... }
|
||||
// Only admins
|
||||
```
|
||||
|
||||
### Scoped Endpoint
|
||||
```typescript
|
||||
@RequireAuthenticatedUser()
|
||||
@Get('leagues/:leagueId/admin')
|
||||
getLeagueAdmin(
|
||||
@Param('leagueId') leagueId: string,
|
||||
@User() user: UserEntity
|
||||
) {
|
||||
// Check if user is league admin
|
||||
this.leagueService.verifyLeagueAdmin(leagueId, user.id);
|
||||
...
|
||||
}
|
||||
// Check scope in service
|
||||
```
|
||||
|
||||
## Error Handling
|
||||
|
||||
### API Returns
|
||||
- **401 Unauthorized**: No/invalid session
|
||||
- **403 Forbidden**: Has session but no permission
|
||||
- **404 Not Found**: Resource doesn't exist OR non-disclosure
|
||||
|
||||
### Client Handles
|
||||
```typescript
|
||||
try {
|
||||
const data = await apiFetch('/api/admin/users');
|
||||
return data;
|
||||
} catch (error) {
|
||||
if (error.message.includes('401')) {
|
||||
// Redirect to login
|
||||
window.location.href = '/auth/login';
|
||||
} else if (error.message.includes('403')) {
|
||||
// Show access denied
|
||||
toast.error('You need admin access');
|
||||
router.push('/dashboard');
|
||||
} else {
|
||||
// Show error
|
||||
toast.error(error.message);
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
## Common Mistakes
|
||||
|
||||
### ❌ Wrong
|
||||
```typescript
|
||||
// Client making security decisions
|
||||
function AdminPage() {
|
||||
const { session } = useAuth();
|
||||
if (session?.role !== 'admin') return <AccessDenied />;
|
||||
return <AdminDashboard />;
|
||||
}
|
||||
|
||||
// API trusting client
|
||||
@Post('delete')
|
||||
deleteUser(@Body() body: { userId: string }) {
|
||||
const userId = body.userId; // Could be anyone!
|
||||
...
|
||||
}
|
||||
|
||||
// Middleware doing too much
|
||||
if (user.role === 'admin') { // Wrong place for this!
|
||||
return NextResponse.next();
|
||||
}
|
||||
```
|
||||
|
||||
### ✅ Correct
|
||||
```typescript
|
||||
// Client handles UX only
|
||||
function AdminPage() {
|
||||
return (
|
||||
<RoleLayout requiredRoles={['admin']}>
|
||||
<AdminDashboard />
|
||||
</RoleLayout>
|
||||
);
|
||||
}
|
||||
|
||||
// API is source of truth
|
||||
@Post('delete')
|
||||
@RequireRoles('admin')
|
||||
deleteUser(@User() user: UserEntity, @Body() body: { userId: string }) {
|
||||
// user.id is from session, body.userId is target
|
||||
// Service verifies permissions
|
||||
...
|
||||
}
|
||||
|
||||
// Middleware only checks auth
|
||||
if (!hasAuthCookie) {
|
||||
return redirect('/login');
|
||||
}
|
||||
// Let API handle roles
|
||||
```
|
||||
|
||||
## Testing Checklist
|
||||
|
||||
### Before Deploy
|
||||
- [ ] Unauthenticated user can't access protected routes
|
||||
- [ ] Authenticated user can access their routes
|
||||
- [ ] Wrong role gets redirected/denied
|
||||
- [ ] Session expiry redirects to login
|
||||
- [ ] API returns proper 401/403 codes
|
||||
- [ ] Public routes work without login
|
||||
|
||||
### Quick Test Commands
|
||||
```bash
|
||||
# Test API directly
|
||||
curl -I http://localhost:3000/api/admin/users
|
||||
# Should return 401 (no auth)
|
||||
|
||||
# Test with session
|
||||
curl -I http://localhost:3000/api/admin/users \
|
||||
-H "Cookie: gp_session=valid_token"
|
||||
# Should return 200 or 403 depending on role
|
||||
|
||||
# Test public route
|
||||
curl -I http://localhost:3000/api/leagues/all
|
||||
# Should return 200
|
||||
```
|
||||
|
||||
## Migration Steps
|
||||
|
||||
1. **Simplify middleware** - Remove role logic
|
||||
2. **Create clean guards** - AuthLayout, RoleLayout
|
||||
3. **Update layouts** - Replace old RouteGuard
|
||||
4. **Test all routes** - Check redirects work
|
||||
5. **Verify API** - All endpoints have proper decorators
|
||||
|
||||
## Remember
|
||||
|
||||
- **Server**: Security, permissions, data filtering
|
||||
- **Client**: UX, loading states, redirects
|
||||
- **Flow**: Always the same, always predictable
|
||||
- **Debug**: Check each layer in order
|
||||
|
||||
**When in doubt**: The API decides. The client just shows what the API says.

# Unified Authentication & Authorization Architecture
|
||||
|
||||
## Executive Summary
|
||||
|
||||
This document defines a **clean, predictable, and secure** authentication and authorization architecture that eliminates the current "fucking unpredictable mess" by establishing clear boundaries between server-side and client-side responsibilities.
|
||||
|
||||
## Current State Analysis
|
||||
|
||||
### What's Wrong
|
||||
|
||||
1. **Confusing Layers**: Middleware, RouteGuards, AuthGuards, Blockers, Gateways - unclear hierarchy
|
||||
2. **Mixed Responsibilities**: Server and client both doing similar checks inconsistently
|
||||
3. **Inconsistent Patterns**: Some routes use middleware, some use guards, some use both
|
||||
4. **Role Confusion**: Frontend has role logic that should be server-only
|
||||
5. **Debugging Nightmare**: Multiple layers with unclear flow
|
||||
|
||||
### What's Actually Working
|
||||
|
||||
1. **API Guards**: Clean NestJS pattern with `@Public()`, `@RequireRoles()`
|
||||
2. **Basic Middleware**: Route protection works at edge
|
||||
3. **Auth Context**: Session management exists
|
||||
4. **Permission Model**: Documented in AUTHORIZATION.md
|
||||
|
||||
## Core Principle: Server as Source of Truth
|
||||
|
||||
**Golden Rule**: The API server is the **single source of truth** for authentication and authorization. The client is a dumb terminal that displays what the server allows.
|
||||
|
||||
### Server-Side Responsibilities (API)
|
||||
|
||||
#### 1. Authentication
|
||||
- ✅ **Session Validation**: Verify JWT/session cookies
|
||||
- ✅ **Identity Resolution**: Who is this user?
|
||||
- ✅ **Token Management**: Issue, refresh, revoke tokens
|
||||
- ❌ **UI Redirects**: Never redirect, return 401/403
|
||||
|
||||
#### 2. Authorization
|
||||
- ✅ **Role Verification**: Check user roles against requirements
|
||||
- ✅ **Permission Evaluation**: Check capabilities (view/mutate)
|
||||
- ✅ **Scope Resolution**: Determine league/sponsor/team context
|
||||
- ✅ **Access Denial**: Return 401/403 with clear messages
|
||||
- ❌ **Client State**: Never trust client-provided identity
|
||||
|
||||
#### 3. Data Filtering
|
||||
- ✅ **Filter sensitive data**: Remove fields based on permissions
|
||||
- ✅ **Scope-based queries**: Only return data user can access
|
||||
- ❌ **Client-side filtering**: Never rely on frontend to hide data
|
||||
|
||||
### Client-Side Responsibilities (Website)
|
||||
|
||||
#### 1. UX Enhancement
|
||||
- ✅ **Loading States**: Show "Verifying authentication..."
|
||||
- ✅ **Redirects**: Send unauthenticated users to login
|
||||
- ✅ **UI Hiding**: Hide buttons/links user can't access
|
||||
- ✅ **Feedback**: Show "Access denied" messages
|
||||
- ❌ **Security**: Never trust client checks for security
|
||||
|
||||
#### 2. Session Management
|
||||
- ✅ **Session Cache**: Store session in context
|
||||
- ✅ **Auto-refresh**: Fetch session on app load
|
||||
- ✅ **Logout Flow**: Clear local state, call API logout
|
||||
- ❌ **Role Logic**: Don't make decisions based on roles
|
||||
|
||||
#### 3. Route Protection
|
||||
- ✅ **Middleware**: Basic auth check at edge
|
||||
- ✅ **Layout Guards**: Verify session before rendering
|
||||
- ✅ **Page Guards**: Additional verification (defense in depth)
|
||||
- ❌ **Authorization**: Don't check permissions, let API fail

## Implementation: Clean Route Protection
|
||||
|
||||
### Step 1: Simplify Middleware (Edge Layer)
|
||||
|
||||
**File**: `apps/website/middleware.ts`
|
||||
|
||||
```typescript
|
||||
import { NextResponse } from 'next/server';
|
||||
import type { NextRequest } from 'next/server';
|
||||
|
||||
/**
|
||||
* Edge Middleware - Simple and Predictable
|
||||
*
|
||||
* Responsibilities:
|
||||
* 1. Allow public routes (static assets, auth pages, discovery)
|
||||
* 2. Check for session cookie on protected routes
|
||||
* 3. Redirect to login if no cookie
|
||||
* 4. Let everything else through (API handles authorization)
|
||||
*/
|
||||
export function middleware(request: NextRequest) {
|
||||
const { pathname } = request.nextUrl;
|
||||
|
||||
// 1. Always allow static assets and API routes
|
||||
if (
|
||||
pathname.startsWith('/_next/') ||
|
||||
pathname.startsWith('/api/') ||
|
||||
pathname.match(/\.(svg|png|jpg|jpeg|gif|webp|ico|css|js)$/)
|
||||
) {
|
||||
return NextResponse.next();
|
||||
}

### Step 2: Clean Layout Guards (Client Layer)
|
||||
|
||||
**File**: `apps/website/lib/guards/AuthLayout.tsx`
|
||||
|
||||
```typescript
|
||||
'use client';
|
||||
|
||||
import { ReactNode, useEffect } from 'react';
|
||||
import { useRouter } from 'next/navigation';
|

* 2. Show loading state while checking
|
||||
* 3. Redirect to login if no session
|
||||
* 4. Render children if authenticated
|
||||
*
|
||||
* Does NOT check permissions - that's the API's job
|
||||
*/
|

|
||||
|
||||
// Show loading state
|

if (loading) {
|

<div className="min-h-screen flex items-center justify-center bg-deep-graphite">
|
||||
<LoadingState message="Verifying authentication..." />
|
||||
</div>
|

}
|

|
||||
// Render protected content
|
||||
return <>{children}</>;
|
||||
}
|
||||
```
|
||||
|
||||
### Step 3: Role-Based Layout (Client Layer)
|
||||
|
||||
**File**: `apps/website/lib/guards/RoleLayout.tsx`
|
||||
|
||||
```typescript
|
||||
'use client';
|
||||
|
||||
import { ReactNode, useEffect } from 'react';
|
||||
import { useRouter } from 'next/navigation';
|
||||
import { useAuth } from '@/lib/auth/AuthContext';
|

* 1. Verify user session exists
|
||||
* 2. Show loading state
|
||||
* 3. Redirect if no session OR insufficient role
|
||||
* 4. Render children if authorized
|
||||
*
|
||||
* Note: This is UX enhancement. API is still source of truth.
|
||||
*/
|
||||
export function RoleLayout({
|
||||
children,
|
||||
requiredRoles,
|
||||
redirectTo = '/auth/login'
|
||||
}: RoleLayoutProps) {
|
||||
const router = useRouter();
|
||||
const { session, loading } = useAuth();
|
||||
|
||||
useEffect(() => {
|
||||
if (loading) return;
|
||||
|
||||
// No session? Redirect
|
||||
if (!session) {
|
||||
const returnTo = window.location.pathname;
|
||||
router.push(`${redirectTo}?returnTo=${encodeURIComponent(returnTo)}`);
|
||||
return;
|
||||
}
|
||||
|
||||
// Has session but wrong role? Redirect
|
||||
if (requiredRoles.length > 0 && !requiredRoles.includes(session.role || '')) {
|
||||
// Could redirect to dashboard or show access denied
|
||||
router.push('/dashboard');
|
||||
return;
|
||||
}
|
||||
}, [loading, session, router, requiredRoles, redirectTo]);
|
||||
|
||||
if (loading) {
|
||||
return (
|
||||
<div className="min-h-screen flex items-center justify-center bg-deep-graphite">
|
||||
<LoadingState message="Verifying access..." />
|
||||
</div>
|
||||
);
|
||||
}
|
||||
|
||||
if (!session || (requiredRoles.length > 0 && !requiredRoles.includes(session.role || ''))) {
|
||||
return null;
|
||||
}
|
||||
|
||||
return <>{children}</>;
|
||||
}
|
||||
```
|
||||
|
||||
### Step 4: Usage Examples
|
||||
|
||||
#### Public Route (No Protection)
|
||||
```typescript
|
||||
// app/leagues/page.tsx
|
||||
export default function LeaguesPage() {
|
||||
return <LeaguesList />;
|
||||
}
|
||||
```
|
||||
|
||||
#### Authenticated Route
|
||||
```typescript
|
||||
// app/dashboard/layout.tsx
|
||||
import { AuthLayout } from '@/lib/guards/AuthLayout';
|
||||
|
||||
export default function DashboardLayout({ children }: { children: ReactNode }) {
|
||||
return (
|
||||
<AuthLayout requireAuth={true}>
|
||||
<div className="min-h-screen bg-deep-graphite">
|
||||
{children}
|
||||
</div>
|
||||
</AuthLayout>
|
||||
);
|
||||
}
|
||||
|
||||
// app/dashboard/page.tsx
|
||||
export default function DashboardPage() {
|
||||
// No additional auth checks needed - layout handles it
|
||||
return <DashboardContent />;
|
||||
}
|
||||
```
|
||||
|
||||
#### Role-Protected Route
|
||||
```typescript
|
||||
// app/admin/layout.tsx
|
||||
import { RoleLayout } from '@/lib/guards/RoleLayout';
|
||||
|
||||
export default function AdminLayout({ children }: { children: ReactNode }) {
|
||||
return (
|
||||
<RoleLayout requiredRoles={['owner', 'admin']}>
|
||||
<div className="min-h-screen bg-deep-graphite">
|
||||
{children}
|
||||
</div>
|
||||
</RoleLayout>
|
||||
);
|
||||
}
|
||||
|
||||
// app/admin/page.tsx
|
||||
export default function AdminPage() {
|
||||
// No additional checks - layout handles role verification
|
||||
return <AdminDashboard />;
|
||||
}
|
||||
```
|
||||
|
||||
#### Scoped Route (League Admin)
|
||||
```typescript
|
||||
// app/leagues/[id]/settings/layout.tsx
|
||||
import { AuthLayout } from '@/lib/guards/AuthLayout';
|
||||
import { LeagueAccessGuard } from '@/components/leagues/LeagueAccessGuard';
|
||||
|
||||
export default function LeagueSettingsLayout({
|
||||
children,
|
||||
params
|
||||
}: {
|
||||
children: ReactNode;
|
||||
params: { id: string };
|
||||
}) {
|
||||
return (
|
||||
<AuthLayout requireAuth={true}>
|
||||
<LeagueAccessGuard leagueId={params.id}>
|
||||
<div className="min-h-screen bg-deep-graphite">
|
||||
{children}
|
||||
</div>
|
||||
</LeagueAccessGuard>
|
||||
</AuthLayout>
|
||||
);
|
||||
}
|
||||
```
|
||||
|
||||
### Step 5: API Guard Cleanup
|
||||
|
||||
**File**: `apps/api/src/domain/auth/AuthorizationGuard.ts`
|
||||
|
||||
```typescript
|
||||
import { CanActivate, ExecutionContext, ForbiddenException, Injectable, UnauthorizedException } from '@nestjs/common';
|
||||
import { Reflector } from '@nestjs/core';
|
||||
import { AuthorizationService } from './AuthorizationService';
|
||||
import { PUBLIC_ROUTE_METADATA_KEY } from './Public';
|
||||
import { REQUIRE_ROLES_METADATA_KEY, RequireRolesMetadata } from './RequireRoles';
|
||||
|
||||
type AuthenticatedRequest = {
|
||||
user?: { userId: string };
|
||||
};
|
||||
|
||||
@Injectable()
|
||||
export class AuthorizationGuard implements CanActivate {
|
||||
constructor(
|
||||
private readonly reflector: Reflector,
|
||||
private readonly authorizationService: AuthorizationService,
|
||||
) {}
|
||||
|
||||
canActivate(context: ExecutionContext): boolean {
|
||||
const handler = context.getHandler();
|
||||
const controllerClass = context.getClass();
|
||||
|
||||
// 1. Check if route is public
|
||||
const isPublic = this.reflector.getAllAndOverride<{ public: true } | undefined>(
|
||||
PUBLIC_ROUTE_METADATA_KEY,
|
||||
[handler, controllerClass],
|
||||
)?.public ?? false;
|
||||
|
||||
if (isPublic) {
|
||||
return true;
|
||||
}
|
||||
|
||||
// 2. Get required roles
|
||||
const rolesMetadata = this.reflector.getAllAndOverride<RequireRolesMetadata | undefined>(
|
||||
REQUIRE_ROLES_METADATA_KEY,
|
||||
[handler, controllerClass],
|
||||
) ?? null;
|
||||
|
||||
// 3. Get user identity from request (set by AuthenticationGuard)
|
||||
const request = context.switchToHttp().getRequest<AuthenticatedRequest>();
|
||||
const userId = request.user?.userId;
|
||||
|
||||
// 4. Deny if not authenticated
|
||||
if (!userId) {
|
||||
throw new UnauthorizedException('Authentication required');
|
||||
}
|
||||
|
||||
// 5. If no roles required, allow
|
||||
if (!rolesMetadata || rolesMetadata.anyOf.length === 0) {
|
||||
return true;
|
||||
}
|
||||
|
||||
// 6. Check if user has required role
|
||||
const userRoles = this.authorizationService.getRolesForUser(userId);
|
||||
const hasAnyRole = rolesMetadata.anyOf.some((r) => userRoles.includes(r));
|
||||
|
||||
if (!hasAnyRole) {
|
||||
throw new ForbiddenException(`Access requires one of: ${rolesMetadata.anyOf.join(', ')}`);
|
||||
}
|
||||
|
||||
return true;
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### Step 6: Client Error Handling
|
||||
|
||||
**File**: `apps/website/lib/api/client.ts`
|
||||
|
||||
```typescript
|
||||
/**
|
||||
* API Client with unified error handling
|
||||
*/
|
||||
export async function apiFetch(url: string, options: RequestInit = {}) {
|
||||
const response = await fetch(url, {
|
||||
...options,
|
||||
credentials: 'include',
|
||||
headers: {
|
||||
'Content-Type': 'application/json',
|
||||
...options.headers,
|
||||
},
|
||||
});
|
||||
|
||||
// Handle authentication errors
|
||||
if (response.status === 401) {
|
||||
// Session expired or invalid
|
||||
window.location.href = '/auth/login?returnTo=' + encodeURIComponent(window.location.pathname);
|
||||
throw new Error('Authentication required');
|
||||
}
|
||||
|
||||
// Handle authorization errors
|
||||
if (response.status === 403) {
|
||||
const error = await response.json().catch(() => ({ message: 'Access denied' }));
|
||||
throw new Error(error.message || 'You do not have permission to access this resource');
|
||||
}
|
||||
|
||||
// Handle not found
|
||||
if (response.status === 404) {
|
||||
throw new Error('Resource not found');
|
||||
}
|
||||
|
||||
// Handle server errors
|
||||
if (response.status >= 500) {
|
||||
throw new Error('Server error. Please try again later.');
|
||||
}
|
||||
|
||||
return response;
|
||||
}
|
||||
```
|
||||
|
||||
## Benefits of This Architecture
|
||||
|
||||
### 1. **Clear Responsibilities**
|
||||
- Server: Security and authorization
|
||||
- Client: UX and user experience
|
||||
|
||||
### 2. **Predictable Flow**
|
||||
```
|
||||
User → Middleware → API → Guard → Controller → Response → Client
|
||||
```
|
||||
|
||||
### 3. **Easy Debugging**
|
||||
- Check middleware logs
|
||||
- Check API guard logs
|
||||
- Check client session state
|
||||
|
||||
### 4. **Secure by Default**
|
||||
- API never trusts client
|
||||
- Client never makes security decisions
|
||||
- Defense in depth without confusion
|
||||
|
||||
### 5. **Scalable**
|
||||
- Easy to add new routes
|
||||
- Easy to add new roles
|
||||
- Easy to add new scopes
|
||||
|
||||
## Migration Plan
|
||||
|
||||
### Phase 1: Clean Up Middleware (1 day)
|
||||
- [ ] Simplify `middleware.ts` to only check session cookie
|
||||
- [ ] Remove role logic from middleware
|
||||
- [ ] Define clear public routes list
|
||||
|
||||
### Phase 2: Create Clean Guards (2 days)
|
||||
- [ ] Create `AuthLayout` component
|
||||
- [ ] Create `RoleLayout` component
|
||||
- [ ] Create `ScopedLayout` component
|
||||
- [ ] Remove old RouteGuard/AuthGuard complexity
|
||||
|
||||
### Phase 3: Update Route Layouts (2 days)
|
||||
- [ ] Update all protected route layouts
|
||||
- [ ] Remove redundant page-level checks
|
||||
- [ ] Test all redirect flows
|
||||
|
||||
### Phase 4: API Guard Enhancement (1 day)
|
||||
- [ ] Ensure all endpoints have proper decorators
|
||||
- [ ] Add missing `@Public()` or `@RequireRoles()`
|
||||
- [ ] Test 401/403 responses
|
||||
|
||||
### Phase 5: Documentation & Testing (1 day)
|
||||
- [ ] Update all route protection docs
|
||||
- [ ] Create testing checklist
|
||||
- [ ] Verify all scenarios work
|
||||
|
||||
## Testing Checklist
|
||||
|
||||
### Unauthenticated User
|
||||
- [ ] `/dashboard` → Redirects to `/auth/login?returnTo=/dashboard`
|
||||
- [ ] `/profile` → Redirects to `/auth/login?returnTo=/profile`
|
||||
- [ ] `/admin` → Redirects to `/auth/login?returnTo=/admin`
|
||||
- [ ] `/leagues` → Works (public)
|
||||
- [ ] `/auth/login` → Works (public)
|
||||
|
||||
### Authenticated User (Regular)
|
||||
- [ ] `/dashboard` → Works
|
||||
- [ ] `/profile` → Works
|
||||
- [ ] `/admin` → Redirects to `/dashboard` (no role)
|
||||
- [ ] `/leagues` → Works (public)
|
||||
- [ ] `/auth/login` → Redirects to `/dashboard`
|
||||
|
||||
### Authenticated User (Admin)
|
||||
- [ ] `/dashboard` → Works
|
||||
- [ ] `/profile` → Works
|
||||
- [ ] `/admin` → Works
|
||||
- [ ] `/admin/users` → Works
|
||||
- [ ] `/leagues` → Works (public)
|
||||
|
||||
### Session Expiry
|
||||
- [ ] Navigate to protected route with expired session → Redirect to login
|
||||
- [ ] Return to original route after login → Works
|
||||
|
||||
### API Direct Calls
|
||||
- [ ] Call protected endpoint without auth → 401
|
||||
- [ ] Call admin endpoint without role → 403
|
||||
- [ ] Call public endpoint → 200
|
||||
|
||||
## Summary
|
||||
|
||||
This architecture eliminates the "fucking unpredictable mess" by:
|
||||
|
||||
1. **One Source of Truth**: API server handles all security
|
||||
2. **Clear Layers**: Middleware → API → Guards → Controller
|
||||
3. **Simple Client**: UX enhancement only, no security decisions
|
||||
4. **Predictable Flow**: Always the same path for every request
|
||||
5. **Easy to Debug**: Each layer has one job
|
||||
|
||||
The result: **Clean, predictable, secure authentication and authorization that just works.**
