angular2-jwt | Helper library for handling JWTs in Angular apps | Authentication library

I followed this guide to set up swiper slider in my Angular 8 application.

I get the below error when importing NgxUsefulSwiperModule into app.module.ts

ERROR in ./node_modules/ngx-useful-swiper/fesm2015/ngx-useful-swiper.js Module not found: Error: Can't resolve 'swiper/bundle' in 'C:\Users\Dan\NewAngular\node_modules\ngx-useful-swiper\fesm2015'

I tried deleting the node_modules folder and reinstalling everything but it fails every time.

Can someone please tell me what I'm doing wrong?

This is my package.json file

I want this factory to access the AppConfigurationService and get the appropriate value. The problem is that the JWT factory runs before loadConfig resolves.

AppConfigurationService.ts:

Please help as I am having error after upgrade my global @angular/cli to version 11. I have revert back to version 8. But now this error keep appear when I try to compile.

On both machines I use the same package.json

I'm using primeicons and primeng in my angular app.

If I'm running the angular website/app locally, everything is fine.

But deploying to an IIS server, the icons are not shown - but all other styles are running well.

Is this something in the configuration of the IIS?
