var mqtt = require(‘mqtt’), levelStore = require(‘mqtt-level-store’); manager = levelStore(‘path/to/db’);

var client = mqtt.connect({ port: 8883, incomingStore: manager.incoming, outgoingStore: manager.outgoing }); 我想问一下这段代码中的 manager.incoming, manager.incoming,是不是mqtt-level-store包的属性，如果 是的话，能不能发个mqtt-level-store包的属性连接我， 我想学习一下，我的电脑科学上网不行，用不了谷歌。
