Using promise-funnel for authentication

Authentication.js

import createFunnel from 'promise-funnel'

const funnel = createFunnel()

function fetchData(...options) {
  // This will fail if the user is unauthenticated
  return fetch(...options)
}

function login() {
  // all requests will be stopped while authentication is happening
  funnel.cork()
  
  // do login logic here
  
  // All the requests will happen now that the user is authenticated again
  funnel.uncork()
}

setTimeout(login, 60 * 5 * 1000 /* re-login every five minutes */)

export default {
 fetchData: funnel.wrap(fetchData),
 login,
}
