Uncaught TypeError: WebSocketServer is not a constructor in browser w/ webpack

[EzraWeller]

We're working on a web app using Mithril.js and webpack. Currently getting this error: Uncaught TypeError: WebSocketServer is not a constructor when trying

const WebSocketServer = require('rpc-websockets').Server
const server = new WebSocketServer({port, host})

Locally, the rpc-websocket object looks like:
{ Server: [Getter], Client: [Function: Client] }

In the browser, I get:
{__esModule: true, Client: ƒ} (no Server)

Hi, @EzraWeller, does it work with rpc-websockets version 4.x as expected?

[EzraWeller]

Seems to be the same problem using both ^4.6.1 and the latest.

Edit: Webpack version ^4.41.5 if that helps.

[EzraWeller]

So, we didn't solve this exactly, but we think the answer is pretty simple: we were trying to create a websocket server inside the browser, which is why the option wasn't available.

@EzraWeller: Thanks for the info! Should we update the docs or the api itself to make this more clear? Have any opinions on that?
