Doesn't work on React-Native 0.26.2

Hey I came here from the README at https://github.com/tuanpmt/react-native-mqtt which has now changed saying to use https://github.com/eclipse/paho.mqtt.javascript

I tried playing around with react-native-mqttjs and paho.mqtt.javascript but can't get either working.

react-native-mqttjs doesn't work due to EventEmitter module.exports I think and paho.mqtt.javascript due to it not being a node module.

Do you have any examples of getting either of these to work?

how abort ssl/tls suport?

suports ssl or tls?

EventEmitter module doesn't exist in the module map

I added this library using yarn add tuanpmt/react-native-mqttjs.

I had error EventEmitter module does not exist in the module map or in these directories: some path/react-native-mqttjs/mqtt.js when I'd run app.
