Using libxml-xsd in an electron app fails with bindings error

Question

I would like to validate an XML file based upon its schema in an electron application.

I have an angular2 service which works before the inclusion of my libxml-xsd require statement. As soon as I add this to the top of my service file:

const xsd = require('libxml-xsd');

I run npm run build which executes this :

webpack --progress --profile --colors --display-error-details --display-cached

I see the following new warnings in the output:

WARNING in ./~/bindings/bindings.js

I then run my application by executing : electron main.js which then throws this error in the browsers console:

Uncaught Error: Could not locate the bindings file. Tried:

Could somebody please help me get libxml-xsd running under my application configuration? Does this have anything to do with webpack? If so - how do I change its config to bring in the appropriate files?
