Can I use losant-mqtt,js in my browser? Can I import it as use it as part of the JavaScript on a webpage? ---

I haven’t confirmed it myself, but losant-mqtt is a wrapper around MQTT.js, which is supported in the browser: [https://github.com/mqttjs/MQTT.js#browser](https://github.com/mqttjs/MQTT.js#browser) So with something like Webpack or Browserify, you should be able to use losant-mqtt in the browser. Give it a try and let us know! ---

Worst-case scenario, our [underlying mqtt protocol](https://docs.losant.com/mqtt/overview/) is pretty straightforward, so you could use MQTT.js directly in the browser. ---

Greg, I just confirmed that it works. Check out this gist: [https://gist.github.com/anaptfox/708cd010a53d19b7b7dc029a235ca092](https://gist.github.com/anaptfox/708cd010a53d19b7b7dc029a235ca092) The key is to set the transport to web sockets. I did that here: > Just add `transport: 'ws'` to the Device options. ---

Brandon, Thanks! I had some thoughts along the same line, just not sure how to use the Losant without the wrapper. A bit new to this IoT and MQTT game. Amazingly I had the weather station example up connected to a slack channel AND my edison sending data to Losant in a matter of a couple of hours. Losant is pretty amazing. Greg ---
