Library for Vanilla Javascript Projects

[lmsutools]

Hi developers, is there any way to get this working for a simple javascript project? I'm having hard time getting cryptolens to integrate with a chrome extension made with vanilla javascript.

I know that there are ways to integrate npm modules into a chrome extension, but that's not what I'm looking for. I tried many bundlers like parcel, Browserify and webpack, but they always threw errors.

Can you provide the errors you get? What bundlers have you used, and with what configs?
