This project is a simple realtime chat applications which was created using React, Express and
most importantly Socket.io which is a great and simple library to create websockets for realtime
applications. It allows you to create a room and join it as separate users (via separate tabs or
computers if app would be hosted).
See example down below.
Thanks to this project I have learnt how to implement realtime applications via sockets and grasped a basic idea how chats in real-world applications could be implemented.
