You need a websocket server -- what you have in your server is just a regular HTTP server. The most popular is Socket.IO in which case you also need their client (they handle fallbacks for unsupported browsers, and support several websocket versions). SockJS is another popular package.
WS is another one. Or npm search websocket .
You should use express and Socket.io to make your life easier.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
