Now I'll build the DENNIS anonymous chat frontend following the design inspiration and specifications. Let me start with the authentication system.

I've built the authentication system with login and signup pages that connect to your Java Spring Boot backend. The system includes API client utilities, WebSocket configuration using SockJS and STOMP (matching your exact contract), and JWT token management. The design follows the dark, modern aesthetic from the inspiration with a red accent color for interactive elements.

I've created the home/landing page with a bold hero section, clear call-to-action buttons for anonymous chat or login/signup, and feature highlights. The page follows the dark, modern design aesthetic with large typography and clean layout. Now let me continue with the pairing system.

I've built the pairing system with a loading animation, status updates, and error handling. The screen shows a spinner while searching for a stranger, displays success when paired, and handles errors gracefully. Now let me build the main chat interface with real-time WebSocket messaging.

I've built the real-time chat interface with WebSocket messaging, typing indicators, message bubbles, and connection status. The interface includes header controls for reporting, starting a new chat, and leaving. Now let me add the final reporting feature.

I've completed the DENNIS anonymous chat frontend application. The system includes authentication with login/signup pages, a landing page with anonymous chat option, a pairing system that connects users, a real-time chat interface with WebSocket messaging using SockJS and STOMP, typing indicators, and a comprehensive reporting feature with predefined reasons. The application follows your exact WebSocket contract specifications and connects to your Java Spring Boot backend at localhost:8080 with the correct endpoints and message structure.

To configure the generation, complete these steps:

Now I'll generate the complete Java Spring Boot backend that matches the frontend contract exactly. I'll create all necessary files including entities, repositories, services, controllers, configurations, and a detailed setup guide.

I've created the complete Java Spring Boot backend with all necessary files matching your frontend contract exactly. The backend includes JWT authentication, WebSocket messaging with SockJS and STOMP, MySQL database integration, pairing logic, and reporting functionality. The detailed setup guide walks through installation on Windows with IntelliJ, including troubleshooting and production deployment steps.
