Вот пример:
const request = require('request-promise');
const cheerio = require('cheerio');
const options = {
    url: 'https://www.php.net/manual/ru/function.get-browser.php',
    headers: {
      'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/74.0.3729.169 Safari/537.36'
    }
  };
  function callback (error, response, html) {
      if (!error && response.statusCode == 200) {
          return html;
      } else {
          console.log("error has occured");
          console.log(error);
      }
  }
module.exports = function webData () {  
    try {
        const page = request.get(options, callback);
        var $ = cheerio.load(page);
        var h1 = $('h1.refname');
        console.log(h1);
    } catch(err) {
        console.log(err);
    }   
}
Результат:
initialize {
  options: {
    withDomLvl1: true,
    normalizeWhitespace: false,
    xml: false,
    decodeEntities: true
  },
  _root: initialize {
    '0': {
      type: 'root',
      name: 'root',

      parent: null,
      prev: null,
      next: null
    },
    options: {
      withDomLvl1: true,
      normalizeWhitespace: false,
      xml: false,

    },
    length: 1,

  },

    },
    options: {
