websoket:
pattern:  /websocket
defaults: {
  "controller": "demo-bundle:demo:websocket"
}
requirements:
  method:
    - GET
    - WEBSOCKET

To use websocket you must understand Nodefony Context


class demoController extends nodefony.Controller {

constructor (container, context){
super(container, context);
}

websocketAction (message){
switch( this.method ){
case "GET" :
return this.render('demo-bundle:default:websocket.html.twig', {
  name:"websoket"
});
case "WEBSOCKET" :
if (message){
  // log  message client in terminal
  this.log( message.utf8data , "INFO");
}else{
  // prepare  push messages server
  // send messages to clients
  let i = 0 ;
  let id = setInterval(() => {
    let mess = "i am a  message "+ i +"\n" ;
    // you can use context to send data
    this.context.send(mess);
    //  or call controller method ( renderResponse , render , renderJson )
    this.renderResponse(mess);
    // log  message sending in terminal
    this.log( "send to client :" + mess , "info");
    i++
  }, 1000);

  setTimeout( () =>{
    clearInterval(id);
    // close reason , descripton
    this.context.close(1000, "nodefony controller close socket");
    id = null ;
  }, 10000);
  // event websocket close by client
  this.context.on("onClose", () =>{
    if (id){
      clearInterval(id);
    }
  });
}
break;
default :
throw new error(" method not allowed");
}
}
}
