/* jshint esversion: 6 */ class Mqtt { constructor(host) { const mqtt = require('mqtt'); const client = mqtt.connect(host); client.on('connect', (() => console.log(`MQTT ${host} Connect!`))); //send msg this.pub = (topic, message) => { client.publish(topic, message); }; } } Eclipse에서 es6 문법을 쓸 것이라고 힌트를 주면 된다
