How to use HTTP Basic Auth on dev server?

[Sociopacific]

What problem does this feature solve?

When using vue-cli 2, I could proxy dev server through nginx and use HTTP Basic Auth. In vue-cli 3, I cannot configure proxying through nginx, since hot reload stops working (error: GET GET http://localhost:1111/sockjs-node/info?t=1542390765166 net::ERR_CONNECTION_REFUSED, when requesting sockjs it is used internal host, not the one provided by nginx). How can I configure HTTP Basic Auth?

What does the proposed API look like?

The possibility of proxying through nginx without hot reload error

when requesting sockjs it is used internal host, not the one provided by nginx

you can set the dev-server's public option for this. Also try using a baseUrl with the right host&port:

  baseUrl: 'http://yourhost:yourport',
  devServer: {
    public: 'http://yourhost:yourport'
  }
}

I do not understand how to use these parameters to properly configure proxying through nginx. I've tried every possible combination.
