Web Socket Messenger

University project. The goal of this project is to discover Java Websokets usecases and implement it in the messenger application.

There are 2 modules :

SpringBoot App : used to run client & server servers
React App : used as a web frontend and is connected to the client SpringBoot server

Launch this project :

git clone git@github.com:neeeekitos/web-socket-messenger.git

// Import this project as Maven project in your IDE
// Launch SpringBoot ServerApplication  (web-socket-messenger/backend/src/main/java/server/)

// Before to launch ClientApplication, we have to change a port in web-socket-messenger/backend/src/main/resources/application.properties to 8081
// Launch SpringBoot ClientApplication (web-socket-messenger/backend/src/main/java/client/)

// Next we will launch React web app 
cd web-socket-messenger/frontend/src
yarn // install dependencies
yarn start // start the app on port 3001

Here's a little example of a workflow that roughly illustrates how the application works, using a messages request as an example:

SocketListener is a thread that listens for all incoming BatchEntity responses from Server and dispatch it to the right controller, while the controller retrieves the information from the object Response (extending BatchEntity) and sends to the React App.
