How to stream the streamed data from Websocket to another Websocket?

This is the image to help you understand what are the problems. I am trying to stream my data being streamed by Websocket to another Websocket.

ws.on('message', function (msg){
let off = msg.data.search(/st5/)
if (off !== -1) {
    //console.log(`${msg.data.slice(83,85)}`)
    if (msg.data.slice(83) === ',') {
        console.log(`${msg.data.slice(84,89)}`)



    }
    else {
            console.log(`${msg.data.slice(83,88)}`)
            var k = msg.data.slice(83,88)

            wss.on('connection', wss => {
                wss.send(`${k}`)

            })


    }
}
else{
    if (msg.data.search('~m~~h~') !== -1) {
        ws.send(`${msg.data}`)
        console.log(`TX: ${msg.data}`)
    }
  }
})

When the client connects to the websocket all the data I have received are automatically sent at the exactly same time. I want to keep sending my data not at the connection time with the load of data. Is there anything I have to do with wss.on(‘connection’)?
