Property 'cordova' does not exist on type 'Window'

Error TS2339: Property ‘cordova’ does not exist on type ‘Window’.How to solve this?.i am using in app browser plugin and i am receiving this error on ionic serve

when you have to use window.cordova., just use cordova., or window['cordova'] given that you don’t want to extend Window’s declaration which usually is not a top priority thing during development.
