Linking two apps to call functions?

Question

Programming

There is an application A under Windows and Linux (closed source) that allows you to include custom .dll and .so plugins. I need to link this application with a NodeJS application (open source) via a plugin. That is, I need the NodeJS application to be able to call a function in the plugin of application A , and in turn, so that application A can call the function in the NodeJS application . Some kind of interface for interaction between applications is required. So that in the end one of the two applications turned out. Naturally, you need to pass some parameters in these functions. How is it implemented and on what basis?

Answer 1
