electron-vue, opens the server, of koa in the rederer thread and asks how to configure webpack to achieve hot loading of koa.

currently, there is no modification to its own webpack template, which can realize the hot loading of Vue, but the port will be reoccupied after modifying the code of koa.

I can do thermal loading for individual KOA projects, but the webpack structure of electron-Vue is slightly more complex and unclear.
would like to give some guidance, preferably with a runnable demo. Thank you
