The way you worded this doesn't make too much sense what you're trying to achieve but will try to give you some general guidance.

First of all, you can't run applications on ports lower then 1024 without running them as administrator since they're considered well-known ports and assigned to specific applications. This means you would need to run your application on ports 1025 and above to avoid the permission denied.

Also, Plesk does have built in support for running Node Applications, so you might want to make sure you have it configured to run with the default settings as localhost, then this way you can have plesk configure to pass the request (like port xyz.com port 80 to localhost port 8081).

I understand that this is not very clear.

my topic presents two examples, a launch of the application on port 80, and on port 8081;

port 80 is necessarily open for the web.
I understand that nodejs cannot open an additional service on port 80, but plesk does not run the application natively.

i want to run this application as a standard web application on port 80. but i can't find how to run it correctly

My first topic for subject : Strapi on Plesk Windows, port redirect error

I mean, technically speaking, you could run it on port 80 still but you would need to run the application as and administrator which is not safe to do. Plesk should have a native way of letting you run the application through it's interface using the default settings on port 8081 which should then let you proxy port 80 to port 8081. I just don't know how it's down on Windows since IIS is different compared to Apache and Nginx. Refer to the following articles to get some guidance for hosting a Node application:

thanks, no problem with deployment for nodejs.

by adding the reverse proxy it works,
but i never needed to do this before with my other applications in vuejs/nuxtjs/nextjs
they are shared and globally developed on port 80 / 3000
