Howler.js doesn't work on Ionic 3

Hello guys,

I’m trying to use audio javascript library called howler.js
Howler.js is included in npm and it installs with npm install howler command.
However, it doesn’t work at all on Ionic 3 which is based on typescript.
How can I make it work? should I use typings?
Any idea?

Are you solved this issues?
thanks in advance.
