Probably the best Angular 4+ modal and inline image gallery. Angular upgrade for ng-image-gallery.
- Hammerjs (required for swipe)
npm i -S hammerjs lodash
Then import hammerjs into your project (tip: in you main.ts file), e.g:
import 'hammerjs';
import { enableProdMode } from '@angular/core';
import { platformBrowserDynamic } from '@angular/platform-browser-dynamic';
import { AppModule } from './app/app.module';
import { environment } from './environments/environment';
if (environment.production) {
enableProdMode();
}
document.addEventListener('DOMContentLoaded', () => {
platformBrowserDynamic().bootstrapModule(AppModule)
.catch(err => console.log(err));
});

You can make gallery inline like a carousel by setting conf.inline to true but make sure to change conf.backdropColor as well if you need white backdrop color. Also width and height of the gallery can be adjusted by manually applying css styles with !important flag on gallery element.
You can update gallery images images and gallery configuration conf anytime you want even when gallery is opened but due to Angular's change detection restrictions you must assign these variable to new value instead of changing internal properties as mentioned below.
// change images
this.images = this.images.concat([...]);
// change conf
this.conf = {...};
