sample.js

const CDP = require('chrome-remote-interface');
const chromeLauncher = require('lighthouse/chrome-launcher/chrome-launcher');

function onPageLoad(Runtime) {
  const js = "document.querySelector('title').textContent";
  return Runtime.evaluate({expression: js}).then(result => {
    console.log('Title of page: ' + result.result.value);
  });
}

async function launchChrome() {
  const chrome = await chromeLauncher.launch({
    chromeFlags: ['--disable-gpu', '--headless', '--enable-logging']
  });
  return chrome;
}

launchChrome(true).then(async chrome => {
  CDP({port: chrome.port}, protocol => {
    const {Page, Runtime} = protocol;

    Promise.all([
      Page.enable(),
      Runtime.enable()
    ]).then(() => {
      Page.navigate({url: 'https://www.chromestatus.com/'});

      Page.loadEventFired(() => {
        onPageLoad(Runtime).then(() => {
          protocol.close();
          chrome.kill();
        });
      });
    });
  });
});
