Chat Engine is a real-time chat application that enables users to register, log in, and engage in live chat conversations. The application leverages a serverless architecture model, utilizing state-of-the-art web development technologies.

This project uses the following key technologies:

• Spring Boot: Simplifies the bootstrapping and development of new Spring applications.
• Spring Security: Provides authentication and authorization services.
• Spring Data JPA: Facilitates the integration of JPA-based repositories.
• Spring WebSocket: Manages WebSocket communication.
• Thymeleaf: Serves as a server-side Java template engine.
• Lombok: Reduces boilerplate code in Java.
• MySQL: Acts as the relational database to store user and chat data.
• Maven: Handles project build and dependency management.

The application.properties file contains configurable settings for the database connection, such as the URL, username, and password, as well as application-specific settings like the maximum number of chat messages to retain in history. You can also adjust the server's port and context path if needed:

spring.datasource.url=jdbc:mysql://localhost:3306/chat_engine spring.datasource.username=yourusername spring.datasource.password=yourpassword

8080
