How to run node.js functions inside asp.net core project?

Question

Node.js

Tell me how to run node.js functions inside the asp.net core project?
And vice versa, if you know? Only not through http, but what would be in one box? As I understand it, there the speed is not so lost on unnecessary operations, unlike external requests. I once saw the "bridge" library, but I can't find it anywhere now.
Thanks
