this one is working well both in nodejs and IE,chrome and so on

in node:
var otpObj=new require('xxx.js').jsOTP;
var number=otpObj.hotp('secret',count);
var number1=otpObj.totp('secret',count);

in browser:

<script type='text/javascript' src='xxx.js'> var otpObj=new jsOTP; var number=optObj.hotp('secret',count); var number1=optObj.totp('secret',count); </script>

Hy,

Thanks for your information but i'll we create new version with Typescript and RxJS for async treatment and a browser version will be created too
