Use as a dependency

To install this as a dependency: npm install -D webdriver-manager. The
following is an example running webdriver-manager as a dependency.
The test downloads the providers and starts the selenium server standalone as
detached. After the test, it will shutdown the selenium server standalone.

import {
  Options,
  setLogLevel,
  shutdown,
  start,
  update,
} from 'webdriver-manager';

const options: Options = {
  browserDrivers: [{
    name: 'chromedriver'     // For browser drivers, we just need to use a valid
                             // browser driver name. Other possible values
                             // include 'geckodriver' and 'iedriver'.
  }],
  server: {
    name: 'selenium',
    runAsNode: true,          // If we want to run as a node. By default
                              // running as detached will set this to true.
    runAsDetach: true         // To run this in detached. This returns the
                              // process back to the parent process.
  }
};
setLogLevel('info');          // Required if we webdriver-manager to log to
                              // console. Not setting this will hide the logs.

describe('some web test', () => {
  beforeAll(async () => {
    await update(options);
    await start(options);
  });

  it('should run some web test', async () => {
    // Your async / await web test with some framework.
  });

  afterAll(async () => {
    await shutdown(options);  // Makes the web request to shutdown the server.
                              // If we do not call shutdown, the java command
                              // will still be running the server on port 4444.
  });
});

Use as a command line interface

npm i -g webdriver-manager

webdriver-manager update      // Downloads the latest binaries.
webdriver-manager start       // Starts the selenium server standalone.

Note: Installing globally will not work with Protractor if you are trying to
start a Selenium Standalone server with a "local" or "directConnect". It will
not work for these since Protractor is looking files downloaded locally to
the project.
