Help needed with angular

Hi I'm new to development,
I'm trying to integrate this API to my Angular project on visual studio.
The first step I did was npm install jump.js --save, to my node_modules file.
Second step import jump from 'jump.js' to my app.module.ts
Third step, declare jump class at import:[jump] in app.module.ts.
my angular is not able to run after that.

Is this API angular friendly?
