after connect with start_link the client start sending infinite messages

[cocodrino]

Hi, for me it's not clear how correct use websockex, I did an small websocket server which when receive a message reply with "hello you sent -> your_message", basically I need send a message and get the response

import * as express from 'express';
import * as http from "http";
import * as WebSocket from 'ws';

const app = express();
const server = http.createServer(app);
const wss = new WebSocket.Server({server});

wss.on('connection', (ws: WebSocket) => {
    ws.send("hi I'm ready");
    ws.on('message', (message: string) => {
        console.log(`received ${message}`);
        ws.send(`hello you sent -> ${message}`);
    })
});

server.listen(8999,()=>{
    //para correrlo se puede hacer con ts-node server.ts
    console.log("server running on port 8999")
})

now I'm trying to connect to this server with websockex with this code

defmodule WebsocketCommunicator do
  use WebSockex
  require Logger

  def start_link(opt \\ []) do
    WebSockex.start_link("ws://localhost:8999",__MODULE__,:fake_state,opt)
  end

  def handle_connect(_conn, state) do
    Logger.info("Connected!")
    {:ok, state}
  end

  def echo(client,message) do
    Logger.info("mandando mensaje #{message}")
    WebSockex.send_frame(client, {:text, message})
  end

  def handle_frame({:text,msg},:fake_state) do
    Logger.info("sending --> #{msg}")

    {:reply,{:text,msg},:fake_state}
  end
end

but when I try to run this

{:ok,pid} = WebsocketCommunicator.start_link()

I get

sending --> hello you sent -> hello you sent -> hello you sent -> hello you sent -> hello you sent -> hello you sent -> hello you sent -> hello you sent -> hello you sent -> hello you sent -> hello you sent -> hello you sent -> hello you sent -> hello you sent -> hello you sent -> hello you sent -> hello you sent -> hello you sent -> hello you sent -> hello you sent -> hello you sent -> hello you sent -> hello you sent -> hello you sent -> hello you sent -> hello you sent -> hello you sent -> hello you sent -> hello you sent -> hello you sent -> hello you sent -> hello you sent -> hello you sent -> hello you sent -> hello you sent -> hello you sent -> hello you sent -> hello you sent

how can send and get the websocket response with websockex???...why after connect with start_link start sending messages?...

sorry for my noobs questions, thank you so much

wss.on('connection', (ws: WebSocket) => {
    ws.send("hi I'm ready"); // <--- This Line
    ws.on('message', (message: string) => {
        console.log(`received ${message}`);
        ws.send(`hello you sent -> ${message}`);
    })
});

As soon as you're connected you're sending a message. Then you have a weird loop where each side is handling the text message by replying with the message. they just recieved.

ws.send(`hello you sent -> ${message}`);

{:reply,{:text,msg},:fake_state}

Just make it so that one side doesn't reply with the message that was sent.
