Application Architecture

System Overview

AzoozGAT Platform follows a JAMstack architecture with serverless backend:

┌───────────────┐     ┌─────────────────────┐     ┌────────────────────┐

Data Flow

  • Static Content: Quiz info, policies, and landing page content built at compile time
  • Dynamic Data: User profiles, quiz attempts, and reports stored in Firestore
  • Real-time Features: Live quiz sessions and leaderboard updates via Firestore listeners

Implementation Deep Dive

Authentication & Role Management

Authentication is handled by Firebase Auth, with custom logic for role-based access:

// src/lib/auth/roleManager.ts
export function getRoleLevel(role: UserRole): RoleLevel {
  return ROLE_LEVELS[role] || ROLE_LEVELS.guest;
}

export function canAccessPath(user: User | null, path: string): boolean {
  // ...checks for admin, pro tier, and public paths
}
  • Roles: admin, user, old_user, subscribed, new_user
  • Access Levels: Pro tier (user|old_user|subscribed) unlocks premium features
  • Server-Side User Creation: Admins can create users via Firebase Admin SDK

Quiz System

Quizzes are managed via Firestore and custom admin interfaces:

  • Quiz Creation: Admins can create/edit quizzes with rich options
  • Quiz Attempt: Users take timed quizzes, with auto-submit and instant feedback
  • Reporting: Quiz attempts are stored and analyzed for leaderboard and progress tracking
// src/lib/db-client/db_quiz.ts
export async function getQuizzesPaginated(options: PaginationOptions = {}): Promise<PaginationResult<Quiz>> {
  // ...Firestore query with pagination
}
  • Leaderboard: Secure, real-time leaderboard with best attempt logic
  • Analytics: Admin dashboard shows user progress, quiz stats, and more

UI & Responsive Design

  • Tailwind CSS: Rapid, utility-first styling
  • shadcn/ui: Accessible, customizable components (sidebar, dialog, table, etc.)
  • Responsive Layouts: Mobile-first design, tested across devices
<div className="flex flex-col md:flex-row">
  <Sidebar />
  <main className="flex-1">{children}</main>
</div>

Security

  • Firestore Rules: Strict access control for users, quizzes, and reports
  • Role-Based Permissions: Only admins can manage users/quizzes; pro tier required for premium features
  • Input Validation: Zod + React Hook Form for frontend validation; Firestore rules for backend
// firestore.rules (simplified)
match /users/{userId} {
  allow read: if isOwner(userId) || isAdmin();
  allow create: if isOwner(userId);
  allow update: if isOwner(userId) || isAdmin();
}

Performance Optimization

  • Static Site Generation: Landing and info pages built at compile time
  • Code Splitting: Dynamic imports for heavy dashboard components
  • Image Optimization: Next.js Image for fast, responsive images
  • Database Query Optimization: Paginated queries, indexed fields

Challenges & Solutions

1. Role-Based Access Control

Problem: Complex permission logic for quizzes, downloads, and admin features
Solution: Centralized role manager, server-side checks, and UI feedback for restricted actions

2. Real-time Quiz & Leaderboard

Problem: Ensuring real-time updates without excessive reads
Solution: Firestore listeners, batched updates, and secure leaderboard logic

3. TypeScript Integration

Problem: Type safety with dynamic Firestore data
Solution: Comprehensive interfaces, Zod validation, and strict linting

4. Accessibility & UI Consistency

Problem: Ensuring keyboard navigation and screen reader support
Solution: shadcn/ui components, semantic HTML, and regular accessibility audits
