Chat Application

 I am developing a messaging application using Spring and React. The program has private messaging and group messaging feature. In addition, it supports features such as file sending and video calling. Users also have specific roles. These roles limit which requests users can access. In addition, it is verified whether users log into the system with the hashing function or whether the token validity period has passed. In frontend part, I used the popular react structures (useNavigate, useState, useContext, Redux, etc) in the application that was developed with React. 

Used Technologies: 

Spring Boot 3🔸Spring Framework 6🔸Java Security Configuration (all Java, no xml)🔸Hibernate/JPA CRUD🔸Spring Boot 3 Security🔸MySQL🔸React (useState, UseEffect)🔸Javascript, Typescript, HTML/CSS🔸Bcrypt, Jwt🔸Firebase🔸Web Socket🔸Git/Github🔸Spring boot application architecture (DAO, Service, Controller)
