Backend Assignment

Implement a chat application in Vanilla Node JS using SSE (Server sent events)

Note that you can only use the modules from the Node standard library and that's it. You are not allowed to even have a node_modules folder inside the project.

A sample client is provided for a minimal Chat UI

Objectives

Here are the things that the application should do

• Serving the frontend html file to the browser
• Ability to have multiple chat rooms
• Ability to broadcast messages to a particular chatroom the user is connected to
• Users can be anonymous - no need for authentication (Just to keep it simple)
• Online Presence (Counter of active clients)
• Chat history - if a user joins a room they should be able to see the chat history.
