Using OpenSeadragon Plugins in Angular

问题

I'm trying to use a plugin for OpenSeadragon library in Angular. Plugin is OpenSeadragonSelection. However, it is pure JS and this causes some problems.

I tried to integrate it in my project exactly as described. However, when I try

var selection = viewer.selection(options);

I get the following error:

Property 'selection' does not exist on type 'Viewer'

In the browser console I get:

Uncaught ReferenceError: require is not defined
at openseadragonselection.js:1

Even though I added the script to my angular.json

"scripts": [
          "./node_modules/openseadragon/build/openseadragon/openseadragon.min.js",
          "./node_modules/openseadragonselection/dist/openseadragonselection.js"

        ]

Any Ideas how to successfully use the plugin in an Angular project?
