Possible values of the titleBarStyle option are:

default or not specified, results in the standard gray opaque Mac title bar.
hidden results in a hidden title bar and a full size content window, yet the title bar still has the standard window controls ("traffic lights") in the top left.
hidden-inset results in a hidden title bar with an alternative look where the traffic light buttons are slightly more inset from the window edge. It is not supported on macOS 10.9 Mavericks, where it falls back to hidden.
The webPreferences option is an object that can have the following properties:

nodeIntegration Boolean - Whether node integration is enabled. Default is true.
preload String - Specifies a script that will be loaded before other scripts run in the page. This script will always have access to node APIs no matter whether node integration is turned on or off. The value should be the absolute file path to the script. When node integration is turned off, the preload script can reintroduce Node global symbols back to the global scope. See example here.
session Session - Sets the session used by the page. Instead of passing the Session object directly, you can also choose to use the partition option instead, which accepts a partition string. When both session and partition are provided, session will be preferred. Default is the default session.
partition String - Sets the session used by the page according to the session's partition string. If partition starts with persist:, the page will use a persistent session available to all pages in the app with the same partition. If there is no persist: prefix, the page will use an in-memory session. By assigning the same partition, multiple pages can share the same session. Default is the default session.
