Is there are way to re-webapck npm package, using wasm which was webpacked ans use it for vscode plugin development?

Question

First of all, I created the npm package which uses wasm converted from rust-lang using wasm-pack.

https://www.npmjs.com/package/markdown_img_url_editor

node_modules/markdown_img_url_editor :

Now, I want to re-webpack the package and use it.

https://github.com/yumetodo/vscode-google-photos-uploader/tree/feat/follow_markdown_img_url_editor_breaking_change

However, currently, there are at least two problems.

1. .wasm was not copied to webpack dest directory

2. After manually copied .wasm files,
   
   on debug execution, TypeError: Cannot read property 'call' of undefined at __webpack_require__ error is occurred.

How should I resolve these problems?

stop re-webpack and mark wasm package as externals. https://webpack.js.org/configuration/externals/
