How do I fingerprint images and other static assets in Ionic for cache busting?

I have extended default web pack config in Ionic v3 for forcing cache buster. I am able to fingerprint generated JavaScript artifacts, but I am unable to fingerprint images and JSON files under the assets folder. I took Help from Bundled files and cache-busting. An excerpt of webpack config.js The above is the approach for fingerprinting JavaScript bundles, and it’s working fine. I want to add hashes/fingerprint images and JSON files inside the assets folder. I used the same approach for images also, but it did not work. I have extended webpack config.js and added a new rule for images.
