Hello

I’d like to implement a external javascript library ([alphaTab](https://www.alphatab.net/)). How do I do this in typescript/IONIC?  
Is there somebody who could help me with this? I imported the directory in the assets folder. But I can’t seem to import it in typescript. I get the error message: 'TS2306: File ‘AlphaTab.js’ is not a module etc.

Thanks in advance!
