Modified Files (4)

1. Middleware

File: src/middleware.ts

Changes:

// Added imports
import { isPublicRoute, requiresAuth } from "@/permissions/routes";

// Simplified logic to use RBAC route config
if (isPublicRoute(pathname)) {
  return NextResponse.next();
}

if (requiresAuth(pathname)) {
  // ... authentication check
}

Impact: Middleware now uses centralized route configuration instead of hardcoded paths.

2. Application Root

File: src/pages/_app.tsx

Changes:

// Added import
import { RBACProvider } from "@/contexts/RBACContext";

// Added to component tree (after WalletProvider)
<WalletProvider>
  <RBACProvider>
    <ProvidersInner ... />
  </RBACProvider>
</WalletProvider>

// Fixed ProvidersInner to properly render children

Impact: RBAC context is now available throughout the application.

3. Wallet Context

File: src/contexts/WalletContext.tsx

Changes:

// Added imports
import {
  getAvailableWallets,
  connectWallet,
  disconnectWallet,
  switchWallet as switchWalletService,
  restoreSession,
  pollSession,
} from "@/services/walletService";
import type { WalletId, WalletMeta } from "@/types/wallet";

// Fixed duplicate code in disconnect function
// Fixed undefined 'address' reference in connect function

Impact: Fixed bugs and ensured proper wallet service integration.

4. Navbar Component

File: src/components/Navbar.tsx

Changes:

// Added useMemo for activeWalletMeta
const activeWalletMeta = useMemo(
  () => availableWallets.find((w) => w.id === walletType),
  [availableWallets, walletType]
);

Impact: Fixed undefined variable that would cause runtime errors.

API Reference

Hooks

// Main hook - provides all functionality
const { user, role, hasPermission, isAdmin } = useRBAC();

// Convenience hooks
const canView = usePermission(Permission.VIEW_ANALYTICS);
const canManage = usePermissions([Permission.CREATE, Permission.DELETE]);
const isAtLeastPowerUser = useRole(UserRole.POWER_USER);

Guard Components

// Component-level
<PermissionGuard permission={Permission.VIEW_ANALYTICS}>
  <Content />
</PermissionGuard>

// Page-level
<RouteGuard minRole={UserRole.ADMIN}>
  <AdminPage />
</RouteGuard>

// HOC pattern
export default withRouteGuard(MyPage);

Utilities

// Check permissions
const user = getUserRole(address);
const canAccess = hasPermission(user, Permission.VIEW_ANALYTICS);
const result = checkPermissions(user, [Permission.CREATE], UserRole.ADMIN);

// Route checks
const routeAccess = getRouteAccess("/analytics");
const canAccess = canAccessRoute(user, routeAccess);

Import Paths Reference

// Types
import { UserRole, Permission } from "@/types/rbac";

// Utilities
import { hasPermission, getUserRole } from "@/permissions";

// Context & Hooks
import { useRBAC, usePermission } from "@/contexts/RBACContext";

// Guards
import { PermissionGuard, RouteGuard, withRouteGuard } from "@/components/guards";

// Navigation
import { RoleAwareNav, mainNavItems } from "@/components/RoleAwareNav";

Configuration Reference

Adding a New Role

  1. Add to UserRole enum in src/types/rbac.ts
  2. Add to ROLE_HIERARCHY in src/permissions/rbac.ts
  3. Add permissions to ROLE_PERMISSIONS in src/types/rbac.ts

Adding a New Permission

  1. Add to Permission enum in src/types/rbac.ts
  2. Add to appropriate roles in ROLE_PERMISSIONS
  3. Use in guards/checks as needed

Adding a Protected Route

  1. Add to ROUTE_ACCESS_CONFIG in src/permissions/routes.ts
  2. Or wrap page with RouteGuard component
  3. Or use withRouteGuard() HOC

Testing Checklist

Manual Testing

  • Connect wallet (should get USER role)
  • Check navigation menu (items should filter based on role)
  • Access /dashboard (should work for USER)
  • Access /analytics (should require POWER_USER)
  • Access /admin (should require ADMIN)
  • Disconnect wallet (should revert to GUEST)
  • Check component guards hide/show correctly

Automated Testing (TODO)

  • Unit tests for permission utilities
  • Unit tests for role hierarchy
  • Integration tests for PermissionGuard
  • Integration tests for RouteGuard
  • E2E tests for role-based flows

Migration Checklist

For Existing Pages

  • Identify pages that need protection
  • Determine required role/permissions
  • Add RouteGuard or use withRouteGuard
  • Test access with different roles

For Backend Integration

  • Implement role storage (database/contract)
  • Create API endpoints for role management
  • Update getUserRole() to fetch from backend
  • Add server-side permission validation
  • Implement session management
  • Add audit logging

Breaking Changes

None. All changes are additive and backward compatible.

Dependencies

No new dependencies added. Uses existing React and Next.js features.

Browser Support

Compatible with all browsers supported by Next.js 14:

  • Chrome (latest)
  • Firefox (latest)
  • Safari (latest)
  • Edge (latest)

Performance Impact

Minimal:

  • Permission checks are memoized
  • Context values are optimized with useMemo
  • No additional network requests
  • Route config lookup is O(n) where n ≈ 10-20

Accessibility

  • ✅ Semantic HTML preserved
  • ✅ ARIA labels on loading states
  • ✅ Screen reader friendly error messages
  • ✅ Keyboard navigation maintained
  • ✅ Focus management in guards

Known Limitations

  1. Client-side only: Current implementation is not secure for production
  2. Default role: All users get USER role by default
  3. No persistence: Roles reset on page refresh (until backend integration)
  4. No audit log: Permission checks are not logged
  5. No role management UI: Must be added separately

Future Enhancements

Short-term

  • Add unit tests
  • Add integration tests
  • Create example pages with guards

Medium-term

  • Backend role storage
  • API endpoints
  • Admin UI for role management

Long-term

  • Smart contract integration
  • Time-based permissions
  • Multi-factor authorization
  • Audit dashboard
