I think angular service works are a great choice for this and bring other performance boosts. It provides robust cache info strategies for various types of requests, one of which is assets https://angular.io/guide/service-worker-intro

If you don’t want to go the service worker route I recommend looking into an Angular HttpInterceptors (https://angular.io/api/common/http/HttpInterceptor) and how you could implement a cache at this point responding to requests without it leaving your app
