Error in NodeJS

[Cronoz1994]

An error appears when using the library in NodeJs, in the index.js file related to the window object.

I solved it as follows:
if (typeof window !== 'undefined') {...}

Take it into account for the next update @sakul-budhathoki.
Thaks.

Published the fix on version 0.0.8 on npm.
