Config.xml
Config.xml is a global configuration file that controls many aspects of a cordova application's behavior. This platform-agnostic XML file is arranged based on the W3C's Packaged Web Apps (Widgets) specification, and extended to specify core Cordova API features, plugins, and platform-specific settings.
For projects created with the Cordova CLI (described in The Command-Line Interface), this file can be found in the top-level directory:
app/config.xml
