On the same desktop (local machine),
I need a very simple method to send only text messages, from a desktop application to the browser (javascript);
and vice versa;
in such a way that I do not depend on the use of desktop web server programs such as WAMP, LAMP, MAMP, XAMPP. or frameworks like node.js

Thank very much in advance, for everyone’s attention.

a few lines in code: languages C and javascript or
