    if (
      options.root &&
      options.stateInterface &&
      options.stateInterface !== 'State'
    ) {
      options.stateInterface = stringUtils.classify(options.stateInterface);
    }

    const templateSource = apply(url('./files'), [
      options.root && options.minimal ? filter(_ => false) : noop(),
      applyTemplates({
        ...stringUtils,
        ...(options as object),
        isLib: isLib(host, options),
        environmentsPath,
      }),
      move(parsedPath.path),
    ]);

    return chain([
      branchAndMerge(
        chain([addImportToNgModule(options), mergeWith(templateSource)])
      ),
    ])(host, context);
  };
