Using libxml-xsd in an electronic application fails with binding errors

Using libxml-xsd in an electronic application fails with binding errors

I would like to validate an XML file based on its schema in an electronic application.

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

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

I run npm run buildthat executes this:

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

I see the following new output warnings:

Then I launched my application by doing:, electron main.jswhich then throws this error in the browser console:

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

Can someone help me run libxml-xsd under my application configuration? Does this have anything to do with webpack? If so, how can I change its configuration to bring it to the appropriate files?

bindings.js GitHub.

WebPack

module.exports = {
  plugins: [
    new webpack.IgnorePlugin(/^mock-firmata$/),
    new webpack.ContextReplacementPlugin(/bindings$/, /^$/)
  ],
  externals: ["bindings"]
}
