Warning: DeprecationWarning: Module.issuer: Use new ModuleGraph API

[neoncube2]

This package's documentation for extracting CSS based on entry uses .issuer:

function recursiveIssuer(m) {
  if (m.issuer) {
    return recursiveIssuer(m.issuer);
  } else if (m.name) {
    return m.name;
  } else {
    return false;
  }
}

...

This results in the following warning:

[DEP_WEBPACK_MODULE_ISSUER] DeprecationWarning: Module.issuer: Use new ModuleGraph API

Not a big deal, but it'd be nice for the documentation to be updated at some point :)
