How to use the http-status-codes/index.OK function in http-status-codes

it('should return all public bookmarks', async function () {
      const response = await request(app)
        .get(publicBookmarksApiBaseUrl);

      expect(response.statusCode).to.equal(HttpStatus.OK);
    });

it('should find bookmark by location query param', async function () {
      const response = await request(app)
        .get(basePathApiPublicBookmarks)
        .query({location: verySpecialLocation});

      expect(response.statusCode).to.equal(HttpStatus.OK);
    });

let getScrapedDataForLocation = async (location) => {
  const response = await request.get(location);

  if (response.statusCode == HttpStatus.OK) {
    const $ = cheerio.load(response.text);
    const webpageTitle = $("title").text();
    const metaDescription = $('meta[name=description]').attr("content");
    const webpageData = {
      title: webpageTitle,
      metaDescription: metaDescription,
      publishedOn: '',
      videoDuration: null
    }

    return webpageData;
  }
};
