using in WebWorker

[reservoir-dogs]

I use this library in angular's webworker, I have an error, because in webworker, window is not accessible :

Uncaught ReferenceError: Buffer is not defined
    at eval (converter.js:10)

Could you check nodeJS's environment otherwise ?

Maybe with this

var isNode=new Function("try {return this===global;}catch(e){return false;}");

Thank you
