const toTypeScript = require('json-schema-to-typescript');
const fs = require('fs');

Call existing rules:

return chain([
    externalSchematic('@nrwl/angular', 'lib', {
      name: 'domain',
      directory: options.name,
      tags: `domain:${options.name},type:domain-logic`,
      style: 'scss',
    }),
    (!options.addApp) ?
      noop() :
      externalSchematic('@nrwl/angular', 'app', {
        name: options.name,
        tags: `domain:${options.name},type:app`,
        style: 'scss',
      }),
  ]);
