Getting error on uploaded build of angular on server

[prateek756]

Hi,

I have integrated music-metadata-browser in my Angular 8 project and its working fine on local server of my system but when I uploaded the project on server then getting error on the component in which music-metadata-browser is used. Error that I am getting is:

core.js:6014 ERROR Error: Uncaught (in promise): TypeError: Class extends value undefined is not a constructor or null

The problem seems to be dependency in ID3Stream to Node stream, which is a Node thing. I guess in a lot of cases this is poly-filled, but it does not work here.

I need to investigate a bit further. Maybe I can get rid of the dependency.

Dependency removed: Borewit/music-metadata#580

@prateek756 can you please verify if the issue is resolved with version v2.1.1?
