Here is how can you do it

require('chromedriver');

const path = require('path');
const wd = require('selenium-webdriver');
const chrome = require('selenium-webdriver/chrome');

var builder = new wd.Builder();
var options = new chrome.Options();
var prefs = new wd.logging.Preferences();
var driver;

prefs.setLevel(wd.logging.Type.BROWSER, wd.logging.Level.ALL);
options.setLoggingPrefs(prefs);

driver = builder
    .forBrowser(wd.Browser.CHROME)
    .setChromeOptions(options)
    .build();

driver
    .get(`file://${path.resolve(__dirname, './page.html')}`)
    .then(() => driver.manage().logs().get(wd.logging.Type.BROWSER))
    .then((logs) => {
        console.log(logs);
    })
    .then(() => driver.quit());
