HTML5 music player which use Web Storage (local browser storage) to cache and play music

hop of those help? There probably won't be any as Web Storage has very limited storage space for things such as this.
Although not defined in the specs, Web Storage has a typical limit at 5 mb. That as string. A string is encoded as UTF-16 in JavaScript which means each char takes 2 bytes. On top of that you would have to base-64 encode the binary data which adds 33% to the size.

I wish this helpful for you I asked James Burke on Twitter, and this is his reply:
@parmaeldo not off the top of my head, but have heard of it. Override requirejs.load to do it. Or, if an option for the site, use appcache

Angular cache http in local storage

seems to work fine If you are using RxJS 6, I would recommend you to convert the promise into an observable (using the from operator), and then handle the subsequent operations using pipeable operators, such as tap, or switchMap, depending on the desired behaviour of your method. In this case, we can use switchMap, since we are returning an observable.
import { from } from 'rxjs';
import { switchMap } from 'rxjs/operators';

getData(id) {
  return from(this.storage.get(id))
    .pipe(
      switchMap(content => {
        if (content === null) {
          return this.getObject(id);
        } else {
          return of(content);
        }
      }),
    )
}
myService.getData(id).subscribe((res) => {
  // do the rest here
})
