It's a simple demo of a

• server side websocket implemented in Go and
• the client side web-page with the relevant JS

1. run the server
   • go run main.go
2. make sure the nodejs webgateway live-server, is installed
   • npm install -g live-server
   • it will throw you into a webpage with all files listed in the project
   • select/click "page-with-ws-call.html"
3. run the exercises in the web page
   • in the input field, try any string and also "SELECT *"

I'm using the Gorilla package.
One must upgrade the protocol from http to websockets.
See the Upgrader.

In the 3 main parts of the page it shows that

• it calls a default http-based page
• it sends an automated message (open developer/console in the browser)
• it sends and echos from the server a string and the status
• it retuns some data if you type "SELECT *"
