The title may seems a bit confusing, let me explain.

I'm using an opensource library pico which has a not exported object "pico", so I put ?raw keyword to import it in my frontend project with webpack 5.

import "./lib/pico.js?raw";

And it works properly on my frontend page.

Then when I want to unit test it by jest, I found jest-raw-loader by this post, but the pico seems won't be imported by using this library.

The ?raw on webpack seems more similar as script-loader library.

And jest-raw-loader seems more similar as raw-loader on older versions.

Although webpack official doc suggest to replace raw-loader with ?raw, but they seem different in my case.

I know I can simply edit this pico.js file to export this object. But what if next time I have a far larger library need to be managed? Is there any other way to import this kind of "not exported" object?
