websocket-stream | websockets with the node stream API | Websocket library

I can create an MQTT broker. I can create a web client also. but there is a problem with the device. I try to connect with the IP(ws://192.168.1.240:1883) of the device. The device could not connect to the broker. Web client could connect with WebSocket.

I am trying to make Aedes works as a MQTT broker AND Websocket server. According to that doc: https://github.com/moscajs/aedes/blob/master/docs/Examples.md what i am suppose to understand. Ideally, i want the listener fired up whatever if its a websocket client or a mqtt client.

Is it possible to do something like:

server.broadcast('foo/bar', {data:''})

and all client, websockets and mqtt receive the message ? The doc is not very clear and i am very suprised that websocket-stream is used. It is very low lvl right ?

here some server side code:

I have a app on Heroku and when I run node server.js it's throwing a error and saying Error: Cannot find module 'express'.

I've cleared the npm cache, rebuilt the app, checked the package.json & dependencies. Nothing much is working for me and I'm just looking for solutions now.

I try to solve the issue presented in Node-red: custom nodes waiting for missing types by creating a new node.

I try to use the "mqtt.js example" to obtain a pre-configured mqtt-client/subscriber to add in my palette.

So in the node folder I have the config file, named mqttConfig.json where are placed all data used by mqtt.js to enstablish the connection (ie. broker, topic, qos ...), the structure of this file is the same as in the previous one.

I want to write a wrapper program to inject texts that it receive via websocket to the spawned process
I tried something like this
