How to use the neutrino.Neutrino function in neutrino

return apiOptions.map(options => {
    const api = Neutrino(options)

    // Register built in commands
    api.register('start', start)
    api.register('build', build)
    api.register('inspect', inspect)
    api.register('test', test)

    // Require and use all configured middlewares.
    args.middleware.forEach(middleware => api.use(middleware))

    return api
  })
}

module.exports = on => {
  const options = webpackPreprocessor.defaultOptions;
  const olProvider = new webpack.ProvidePlugin({ ol: "openlayers" });
  options.webpackOptions.plugins = [olProvider];

  const config = Neutrino().use('.neutrinorc.js').config.toConfig();
  options.webpackOptions.module.rules.push(...config.module.rules);
  on("file:preprocessor", webpackPreprocessor(options));
};

const { Neutrino } = require('neutrino');

module.exports = Neutrino()
  .use('.neutrinorc.js')
  .call('eslintrc');
