Cambiar Color Photoshop

Hi Peter -
Thanks for responding to my last question.
OK... I started over. Reinstalled node.js on my Windows 2016 Server.
When I do "pm2 show," I see app.js is running.
"node app.js" worked great from the command prompt. As in, it outputs what it should, within the command prompt window.
I set up the reverse proxy rule in iis for my test site's domain name "amonkeymarket.com".
If you go to amonkeymarket.com/app.js, you will just see the code, not execution of the code. This happens whether I go there with a local browser on the server or remote.
Ideas?
THANK YOU!
