Interactive Quiz Application for TV Shows and Movies

You are a Full-Stack Developer tasked with creating an interactive quiz application focused on TV shows and movies. The application should provide a seamless user experience for content creators and players alike.

Project Requirements:

User Features:

1. Quiz Creation:

   • Enable users to create new quizzes containing up to 20 questions each.
   • Support both multiple-choice and true/false question types.
   • Allow users to upload images or videos as question attachments.
   • Provide a preview mode to review and edit quizzes before publishing.

2. Real-Time Multiplayer:

   • Allow users to create private game rooms with unique, 6-digit codes.
   • Display a "Waiting Room" where players can join the room before the quiz begins.
   • Implement a "Start Quiz" button that initiates the game for all connected players simultaneously.
   • Include a "Ready" button for each player to confirm they are prepared to begin.

3. Scoring System:

   • Award points for correct answers (e.g., 10 points per correct response).
   • Deduct points for incorrect answers (e.g., 5 points subtracted).
   • Display a running total of points for each player during the quiz.
   • Update the scoreboard after each question is answered.

4. Leaderboard:

   • After the quiz ends, display a leaderboard showing the final scores of all participants.
   • Include the user's rank, score, and name on the leaderboard.
   • Allow users to share their score and rank on social media platforms.

Development Constraints:

1. Technical Constraints:

   • Optimize the application for both desktop and mobile browsers.
   • Ensure the application is responsive and performs well across various devices.
   • Implement real-time updates using WebSockets or similar technology for multiplayer functionality.

2. Security Considerations:

   • Encrypt sensitive user data, such as quiz questions and multimedia attachments.
   • Implement authentication and authorization to prevent unauthorized access to quizzes.
   • Use secure connections (HTTPS) throughout the application.

3. Performance Requirements:

   • The application should load within 3 seconds on average for both quiz creators and players.
   • Each quiz question should appear and disappear within 1 second.
   • The leaderboard should update within 2 seconds after a quiz ends.

4. User Experience Guidelines:

   • The interface should be intuitive and easy to navigate, even for first-time users.
   • Provide clear instructions and tooltips for all major features.
   • Use consistent design elements across the application.

Please provide a detailed project plan or a high-level architecture description that addresses these requirements and constraints. Ensure the solution is scalable, maintainable, and aligns with industry best practices for web development.
