Module Based Development

Hi everyone, I Would like to know if it’s possible to expose Functionality that was written in Mendix to other platforms,  For instance, I can take React native widgets and create Pluggable widgets that can be used in Mendix. I would like to know if I can take functionality Modeled in Mendix and Expose to other platforms, for instance, create an auth module in Mendix and allow a react native app to use it, I do not want to use Web services. Any Ideas Would be highly appreciated, Currently  looking at using a Webviews.
