hack for auth redirect w/ react-router 4 and redux-aut-wrapper

hack.js

function handleAuthenticated (dispatch) {
  lock.on('authenticated', ({ accessToken, idToken, state }) => {
    lock.getUserInfo(accessToken, (error, user) => {
      if (error) {
        return dispatch(lockError(error))
      }

      setUser(user)
      setToken(idToken)

      let redirect = null
      try {
        const parsedState = JSON.parse(atob(state))
        redirect = parsedState.redirect
      } catch (_) {
        // NOOP
      }

      dispatch(lockSuccess(user, idToken))
      lock.hide()

      if (redirect !== null) {
        const correctUrl = redirect.replace('?redirect=', '')
        // a hack to make redirect-on-login work
        history.replace(correctUrl) // TODO improve this
      }
    })
  })
}
