mqttjs-mongeriot/src/index.js

A javascript library that allows you to send mqtt commands to an mqtt server.

import Paho from "paho-mqtt";

// What we need to send this command is array of devices, array of commands. In array of commands we need the action and the value/parameter

class mqttCommandEmitter {
  sendMultiCommands(items, commands, connectionAddress, port) {
    let clientID = "clientID_" + parseInt(Math.random() * 100);
    let client = new Paho.Client(connectionAddress, Number(port), clientID);
    client.connect({ onSuccess: onMultiCommandsConnect });

    function onMultiCommandsConnect() {
      for (let d = 0; d < items.length; d++) {
        let topic = `${items[d]}`;
        client.subscribe(topic);
        for (let c = 0; c < commands.length; c++) {
          let value = !commands[c].value;
          let message = `${commands[c]}:${value}`;
          client.publish(topic, message);
        }
      }
    }
  }
  sendCommand(item, commands, connectionAddress, port) {
    let clientID = "clientID_" + parseInt(Math.random() * 100);
    let client = new Paho.Client(connectionAddress, Number(port), clientID);
    client.connect({ onSuccess: onSingleCommandConnect });

    function onSingleCommandConnect() {
      let topic = `${item}`;
      client.subscribe(topic);
      for (let c = 0; c < commands.length; c++) {
        let value = !commands[c].value;
        let message = `${commands[c]}:${value}`;
        client.publish(topic, message);
      }
