Typescript, bootstrap scss module combo in next js 9+

[kennethnwc]

I would like to use scss module and typescript together. In this way , I can do something like
import { btn, btnPrimary } from "./index.scss"; using tools typed-scss-modules to give me a nice auto complete to get the classes I want.

Previously, I am able to do this kind of feature using "@zeit/next-sass.
Since the next js 9+ is coming and it suggests to remove "@zeit/next-sass. I am not able to make it work.

I would like to ask you advice. How to implement this in latest version of next js.

Goals : get rid of @zeit/next-sass and can import bootstrap scss into my own scss.
can import bootstrap classes in anywhere and create own scss for componenet

The previous version is on here
New version with error on here

or you may read this to know why I want this kind of feature.

Thanks in advance.
