(async () => {
  const path = `${__dirname}/service.proto`;
  const packageName = 'PackageName';

  await generateProto({
    path,
    package: packageName,
    services: [ServiceName],
  });

  const app = new Mali(path);
  const serviceMethods = new ServiceName();
  app.use({
    methodName: serviceMethods.methodName,
    methodNameWithEmptyInput: serviceMethods.methodNameWithEmptyInput,
  }, packageName);
