The question is for new projects mainly for ionic native/cordova applications. Reason: I had to change the versions too many times in my last update attempts due to some bugs/quirks.
Ionic* : (probably latest)
Node : (probably 8.9.4 - i.e. LTS version)
npm: (probably 5.6.0 - i.e. latest)
Cordova CLI : ?
Cordova Android Platform: ?
Cordova iOS: ?
Thank you in advance…
