How to use the @nrwl/schematics/src/utils/rules/filter-tree.excludeUnnecessaryFiles function in @nrwl/schematics

function generateNgrxFilesFromTemplates(options: Schema) {
  const name = options.name;
  const moduleDir = path.dirname(options.module);
  const excludeFacade = path => path.match(/^((?!facade).)*$/);

  const templateSource = apply(url('./files'), [
    !options.facade ? filter(excludeFacade) : noop(),
    excludeUnnecessaryFiles(),
    template({ ...options, tmpl: '', ...names(name) }),
    move(moduleDir)
  ]);

  return mergeWith(templateSource);
}
