import {doSomething, feedback} from './yourCode'

//POST some data, returns a Promise
http('https://my.domain.com/chat?locale=en-US', {text:'Hi!'}).then(
    response => doSomething(response),
    error => feedback(error)
)

//GET some data, returns a Promise
http('https://my.domain.com/chat/latest', null, 'GET').then(
    response => doSomething(response),
    error => feedback(error)
)
