How to exchange sessions in installed express applications

Question

I have a rather complicated express application, which is divided into several auxiliary applications, which are also express applications (using app.use() ). How can I seamlessly use the same session between all parts of the application?

Answer 1

Connect-related middleware is "self-aware" as they will not duplicate the work they have already done. For example, if you already have req.session, and both the “root” application and the mounted application use session () middleware, the root application session will work and the other will be ignored. Therefore, it should work as is.
