Fullstack Web Application with Spring Security, JWT, and React

Overview

This application allows users to register, log in, and send/receive messages.

• Spring Security is used for authentication and authorization.
• JWT (JSON Web Token) is utilized for secure token-based user sessions.
• React handles the front-end interface for user interaction.

Logged-out users can send messages, and logged-in users are able to view those messages. Once the user logs in, they can see a list of all previously sent messages.

Features

• User Registration: New users can sign up with a username and password.
• User Login: Returning users can authenticate using JWT.
• Message Sending: Users can send messages before and after logging in.
• Message Viewing: Logged-in users can see all messages sent by others.
