Hi Teja,
I'm a bit too busy to go and sit down for this. I can give you some
pointers:
import {of, BehaviorSubject, combineLatest} from 'rxjs';
import {map} from 'rxjs/operators';
interface Product {
id: number;
name: string;
tags: string[];
}
const products$ = of([] as Product[]);
const searchItems = new BehaviorSubject([] as string[]);
const results$ = combineLatest(products$, searchItems).pipe(
map(([products, tags]) => products.filter(pod => tags.every(tag =>
pod.tags.includes(tag))))
);
completely untested, but the idea is there.
You need to add a thing that includes all products if there are no filters
yet.
(oh, and probably a thing or 2 more ;) )
hope this gets you going,
Regards
Sander
