Open a new window and load a URL.

When is called to create a new window in a web page, a new instance of BrowserWindow will be created for the url and a proxy will be returned to to let the page have limited control over it.

The proxy has limited standard functionality implemented to be compatible with traditional web pages. For full control of the new window you should create a BrowserWindow directly.

The newly created BrowserWindow will inherit the parent window's options by default. To override inherited options you can set them in the features string.[, frameName][, features])

  • url String
  • frameName String (optional)
  • features String (optional)

Returns BrowserWindowProxy - Creates a new window and returns an instance of BrowserWindowProxy class.

The features string follows the format of standard browser, but each feature has to be a field of BrowserWindow's options.


  • Node integration will always be disabled in the opened window if it is disabled on the parent window.
  • Non-standard features (that are not handled by Chromium or Electron) given in features will be passed to any registered webContent's new-window event handler in the additionalFeatures argument.
