How to get the size of data in a Node JS Stream

So I am using this npm Library that returns SoundCloud music as a Stream. But after a while searching for an answer, I couldn’t get an answer. I searched and discovered that it is impossible to get the size of the data in a stream. But, is there a way for me to get the size of the data in that stream because I plan on using the size, to implement download progress in my app. Thanks a lot in advance.
