I am wondering is there an easier way to update cordova plugin?
I googled, found a hook (@ year 2013), but this is not 100% what I want.
I know I can do this
You can't update it. What you can do is uninstall the cordova plugin and add it again.
cordova plugin rm https://github.com/apache/cordova-plugin-camera --save cordova plugin add https://github.com/apache/cordova-plugin-camera --save
