I am not able to make this work in Angular. Here is your example: https://codesandbox.io/s/agitated-panini-tpgb2?file=/src/app/app.component.ts

As you can see, there is an error in the example code where it says new QRCodeStyling() as QRCodeStyling is not constructable.

I have tried changing import * as QRCodeStyling from "qr-code-styling"; to import QRCodeStyling from "qr-code-styling"; but it still doesn't work.

I'm using Angular 12.2.3.

Please advise.

Try this.
Inside your project's tsconfig.json add the following to the "compilerOptions" node
"esModuleInterop":true
