Example code:

const HCCrawler = require('headless-chrome-crawler');
const findChrome = require('chrome-finder'); // https://github.com/gwuhaolin/chrome-finder

(async () => {
  const crawler = await HCCrawler.launch({
    maxRequest: 5,
    maxDepth: 2,
    maxConcurrency: 4,
    obeyRobotsTxt: true,
    executablePath: findChrome(),  // use local Chrome browser
    headless: false,

    evaluatePage: (() => ({
      title: $('title').text(),
    })),

    onSuccess: (result => {
      console.log(result.result.title);
    }),
  });

  crawler.on('maxrequestreached', () => {
    console.log('Maximum request reached!');
  });

  await crawler.queue('http://f4b1.com/');

  await crawler.onIdle();
  await crawler.close();
})().then(() => { console.log('Crawl Terminated'); });
