Default is `false`.
* `type` String - Specifies the type of the window, which applies
additional platform-specific properties. By default it's undefined and you'll
get a regular app window. Supported values:
* On Linux, possible types are `desktop`, `dock`, `toolbar`, `splash`,
`notification`.
* On OS X, possible types are `desktop`, `textured`. The `textured` type adds
metal gradient appearance (`NSTexturedBackgroundWindowMask`). The `desktop`
type places the window at the desktop background window level
The possible values and behaviors of `type` option are platform dependent,
supported values are:
* On Linux, possible types are `desktop`, `dock`, `toolbar`, `splash`,
`notification`.
* On OS X, possible types are `desktop`, `textured`.
* The `textured` type adds metal gradient appearance
(`NSTexturedBackgroundWindowMask`).
* The `desktop` type places the window at the desktop background window level
(`kCGDesktopWindowLevel - 1`). Note that desktop window will not receive
focus, keyboard or mouse events, but you can use `globalShortcut` to receive
input sparingly.
* `titleBarStyle` String, OS X - specifies the style of window title bar.
This option is supported on OS X 10.10 Yosemite and newer. There are three
possible values:
* `default` or not specified, results in the standard gray opaque Mac title
The `titleBarStyle` option is only supported on OS X 10.10 Yosemite and newer.
Possible values 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
* `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
* `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.
* `webPreferences` Object - Settings of web page's features, 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](process.md#event-loaded).
* `partition` String - Sets the session used by the page. 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. If the `partition`
is unset then default session of the app will be used.
* `zoomFactor` Number - The default zoom factor of the page, `3.0` represents
`300%`. Default is `1.0`.
* `javascript` Boolean - Enables JavaScript support. Default is `true`.
* `webSecurity` Boolean - When setting `false`, it will disable the
same-origin policy (Usually using testing websites by people), and set
`allowDisplayingInsecureContent` and `allowRunningInsecureContent` to
`true` if these two options are not set by user. Default is `true`.
* `allowDisplayingInsecureContent` Boolean - Allow an https page to display
content like images from http URLs. Default is `false`.
* `allowRunningInsecureContent` Boolean - Allow a https page to run
JavaScript, CSS or plugins from http URLs. Default is `false`.
* `images` Boolean - Enables image support. Default is `true`.
* `textAreasAreResizable` Boolean - Make TextArea elements resizable. Default
is `true`.

* `experimentalFeatures` Boolean - Enables Chromium's experimental features.
Default is `false`.
* `experimentalCanvasFeatures` Boolean - Enables Chromium's experimental
canvas features. Default is `false`.
* `overlayScrollbars` Boolean - Enables overlay scrollbars. Default is
`false`.
* `sharedWorker` Boolean - Enables Shared Worker support. Default is `false`.
* `directWrite` Boolean - Enables DirectWrite font rendering system on
Windows. Default is `true`.
* `pageVisibility` Boolean - Page would be forced to be always in visible
or hidden state once set, instead of reflecting current window's
visibility. Users can set it to `true` to prevent throttling of DOM
timers. Default is `false`.
The `webPreferences` option is an object that can have 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

Node global symbols back to the global scope. See example
