security – Is it possible to secure node.js code for download an run

Basically we are using node.js on a raspi. So every customer gets a raspi or we install the app on the requested device. To make things easier, we would like to provide the app as download.

I started my search to read following:

How to make exe files from a node.js app?

Understanding it right, there is no possibility to secure / hide the code. It seems, that it is allways possible to access the node.js code.

Is there a way to “compile” the node.js code in an exe file with the code not accessable?

Happy for any information / new starting point
