Import NgxQRCodeModule from ngx-qrcode2 into your app.module.ts:

import { BrowserModule } from '@angular/platform-browser';
import { NgModule } from '@angular/core';
import { NgxQRCodeModule } from 'ngx-qrcode2';

import { AppComponent } from './app.component';


@NgModule({
  declarations: [
    AppComponent
  ],
  imports: [
    BrowserModule,
    NgxQRCodeModule
  ],
  providers: [],
  bootstrap: [AppComponent]
})
export class AppModule { }

Once the library is imported, you can use the ngx-qrcode component in your Angular application:

      <ngx-qrcode 
        [qrc-value] = "value"
        qrc-class = "aclass"
        qrc-errorCorrectionLevel = "L">
        </ngx-qrcode>

You can also specify the QRCode version (1 to 40) explicitely

      <ngx-qrcode 
        qrc-element-type="url" 
        [qrc-value] = "value"
        qrc-version = "40"></ngx-qrcode>
