Can someone point me to how i would add a Socket IO Client to my javascript web application to be informed when topical activity occurs within select NodeBB categories

Maybe try changing "url" in your config.json to http://127.0.0.1:4567

If you provide a cors in config.json it should be an object that gets passed to socket.io so something like.

  "socket.io": {
        "cors": {
		origin: "http://127.0.0.1:*",
		methods: ['GET', 'POST'],
		allowedHeaders: ['content-type'],
	}
    }

@baris In your "allowedHeaders" field, do I use the words 'content-type' .. or does this need to be replaced with some value

That field is passed to https://github.com/expressjs/cors#configuration-options, you might be able to just leave it out If not specified, defaults to reflecting the headers specified in the request's Access-Control-Request-Headers header.

Did you try changing your url field in config.json to http://127.0.0.1:4567? And change the connection code to also use 127.0.0.1:4567 instead of localhost.
