导入同构应用

Question

That doesn't make any sense:

import {Dispatcher} from 'flux';
console.log('Dispatcher', Dispatcher)

I'm using the same boilerplate as usual, the same node version, same compilers, same approaches etc... But the console.log above correctly logs Dispatcher function on server side and undefined on client side.

If i'm doing this:

import Flux from 'flux';
console.log('Flux', Flux)

Server side logs:
Flux { Dispatcher: [Function: Dispatcher] }

Client side:

actions: undefined
constants: {
  TEST_ACTION: "TEST_ACTION" 
}
dispatcher: undefined

Apparently, i'm making just some stupid simple mistake somewhere, but i can't find it.

omg... import looks like that:

import {Dispatcher} from 'flux';

this file is located in folder "flux", i've created index.js file within this folder to make it easier to import Actions.js and Dispatcher.js . For some reason webpack assumed that on client side from 'flux' means import from this folder.
