go-ws-broadcast

A simple implementation of a concurrent broadcast server that dispatches a message to the connected clients via the websocket protocol.

Components:

Broadcast Server

consists of:

• A counter that gets incremented frequently and its value will be broadcasted to all clients.
• A hub component that registers and de-registers clients and broadcasts the counter value to the clients.

Web client

This is a basic React app that acts as a client to the broadcast server, which:

• Establishes a websocket connection to the server and displays a green background upon a successfull connection.
• Starts reading the counter value and displaying it.
• Changes the background to red when the websocket connection closes or errors out.
