Perhaps is a good time to update to v2.7.570 that includes several performance improvements.

@cvjanick when the pdf-js npm dependency is node_modules/pdfjs-dist/build, you have the minified versions available there I think that package is only a dependency and Vadim cannot change anything about it.

At the moment I have 2 changes in my project to make things work: 1) in angular.json

1. app.module.ts

export class AppModule implements DoBootstrap {

    ngDoBootstrap(appRef: ApplicationRef) {
        // Set custom path to the worker to avoid loading of CDN
        if (environment.production) {
            (window as any).pdfWorkerSrc = '/assets/pdf.worker.min.js';
        }

this was needed because the dynamic CDN loading was blocked by the security content policy which we restricted.
