My job in this project is to bring it to the web. So my question is what is the proper/best practices way/architecture that should be followed in such a project where you have many Components writing in different languages?
And is Node.js the best tool/language that can combine components as LinkedIn says: "If you look at Node, the thing it’s best at doing is talking to other services."

I think the proper answer could fill books...

That said, I would suggest to avoid the unholy mess of tiny modules talking to who knows who, by implementing some kind of service bus. If you can get that right, all the languages/subprojects will have to be compatible with the bus only, not with each and every one of the others. That way the complexity will drop from N factorial to 2xN.
