Start the websocket tcp proxy.
go run proxy/proxy.go
Start the TCP server somewhere (lightning node ideally, or example tcp server go run main.go). Use port 19735 or change hardcoded port number.
Connect to the websocket from the browser via 127.0.0.1:8080/proxy
Start passing messages in to the websocket, they will be forwarded to TCP and vis versa.
The example TCP server will respond to messages with a time stamp, useful for testing the proxy and response.
