We have a static prototype, and now we will make it functional. Any chat requires communication between connected clients. Usually, clients do not connect directly but through a server. The server registers connections and forwards the messages. It's pretty clear how to send a message from the client to server, but can we do it in the opposite direction? In the olden days, we had to deal with long-polling techniques. That worked, but with the overhead of HTTP, it is not really suitable when we mean a low latency application. Luckily for us, Electron supports WebSockets. With that API, we can open a full-duplex, bi-directional TCP connection between the client and server. WebSockets provides higher speed and efficiency as compared to HTTP. The technology brings reduction of upto 500:1 in unnecessary HTTP traffic and 3:1 in latency (http://bit.ly/2ptVzlk...
