import {Builder, Capabilities} from 'selenium-webdriver';
import {Options, ServiceBuilder, setDefaultService} from 'selenium-webdriver/chrome';
import * as chromedriver from 'chromedriver';
import * as path from 'path';
import * as fs from 'fs';

const encodeExt = file => {
  const stream = fs.readFileSync(path.resolve(file));
  return Buffer.from(stream).toString('base64');
};

const service = new ServiceBuilder(chromedriver.path).build();
setDefaultService(service);

const driver = new Builder()
  .withCapabilities(Capabilities.chrome())
  .setChromeOptions(new Options()
    .addExtensions(encodeExt('./3.5.2_0.crx')))        <-----+
  .build();                                                  |
                                                             |
                                                             |
