This example will show how to work with websockets in Go. We will build a simple server which echoes back everything we send to it. For this we have to go get the popular gorilla/websocket library like so: 8.2 WebSockets. WebSockets are an important feature of HTML5. It implements browser based remote sockets, which allows browsers to have full-duplex communications with servers. I am trying to build a websocket application using Go where the user enter any string and a websocket displays the string back to client (browser). But I need another api (POST) that can send a message to the websocket and display it in the browser.
