If the Node.js process and C++ program are on the same machine, then perhaps an IPC might help you. What you can do is you can use the local sockets and make Node.js listen on a socket—UNIX Sockets for instance.

What can be even better approach for this—and possible in case your processes are not on the same machines, such as client-server model—then you can utilize the networking APIs of C++, and send the request to Node.js process. Check out this article to learn a bit more on this topic,

JSON[

POST a string and on Node.js you can capture that from the
request body.
