Error in ReactJS

[rakesh-eltropy]

I am getting following error when I try to use react-native-paho-mqtt in ReactJS app.

./node_modules/react-native-paho-mqtt/src/Client.js
Module parse failed: Unexpected token (27:5)
You may need an appropriate loader to handle this file type.

| type ConstructorOptions = {

|   clientId: string,

Can it be used in ReactJS app?
