How to use the @bazel/protractor/protractor-utils.runServer function in @bazel/protractor

module.exports = function(config) {
  // In this example, `@bazel/protractor/protractor-utils` is used to run
  // the server. protractorUtils.runServer() runs the server on a randomly
  // selected port (given a port flag to pass to the server as an argument).
  // The port used is returned in serverSpec and the protractor serverUrl
  // is the configured.
  const isProdserver = path.basename(config.server, path.extname(config.server)) === 'prodserver';
  return protractorUtils
      .runServer(config.workspace, config.server, isProdserver ? '-p' : '-port', [])
      .then(serverSpec => {
        protractor.browser.baseUrl = `http://localhost:${serverSpec.port}`;
      });
};
