// Needed for Atmosphere package RocketChat/meteor-streamer
// It is out of date and was written when Meteor contained lodash
// package. However, we now import lodash as an npm package
// in order to control versions, update flexibly, etc..

// and its introduction was inspired by
// https://github.com/RocketChat/meteor-streamer/issues/40#issuecomment-497627893
import { isEmpty } from 'radash';
