  // Will not do anything if open=false.
  // Remember to start with a slash.
  openPage: '/different/page',

  // Show server address in console (default: true)
  verbose: false,

  // Path to fallback page
  historyApiFallback: '/200.html',

  // Options used in setting up server

  // execute function after server has begun listening
  onListening: function (server) {
    const address = server.address()
    const host = address.address === '::' ? 'localhost' : address.address
    // by using a bound function, we can access options as `this`
    const protocol = this.https ? 'https' : 'http'
    console.log(`Server listening at ${protocol}://${host}:${address.port}/`)
