validate method expects a year, month, and day string parameters and will validate based on such.
var date_validator = require"DateValidator"DateValidator;var is_valid = date_validatorvalidate"2012" "12" "31"; //true

While you can copy the
date-validator.js file from the module's installation directory under
node_modles, an automated script has been provided to assist you in this copy process and to make it more streamlined. To do a client-side install, simply type the following
npm run-script DateValidator client-install
Once you run that command, you'll be prompted to provide the path to which to install
var validator = DateValidator;var is_valid = date_validatorvalidate"2012" "12" "31"; //true
By default, the DateValidator module places itself into the global scope in the browser. If you would prefer to NOT have it be directly attached to the
window object, you can add your own
namespace at the top of the date-validator.js file.
