Prevent redundancy by caching svg icons to minimize repeated requests

I have a collection of info cards on my page, each featuring its own unique illustration along with a set of common icons (SVG) for options such as edit, delete, and more. While the illustrations vary from card to card, the icons remain consistent across all of them.

My goal is to avoid redundant calls for fetching the same icons repeatedly for every card. I am currently using a app-svg custom component to retrieve the SVG icons stored in my /assets folder.

Additionally, I am curious about the behavior when the browser utilizes disk cache, especially on subsequent visits to the same URL. Is it possible to cache the icon once and reuse it? What would be the most effective strategy for achieving this optimization? Thank you!

In my opinion, opting for Angular Service Workers can significantly enhance performance and offer other benefits. These service workers come with advanced cache management strategies for different types of requests, particularly assets. Learn more about Angular Service Workers here.

If you prefer not to utilize service workers, I suggest exploring the use of an Angular HttpInterceptor to effectively implement caching in your application, enabling responses to be handled within the app itself.
