如何在已安装的快递应用中共享会话

Question

I have a fairly complex express based web application that is split up into a few sub apps which are also express apps (using app.use() ). How can I seamlessly use the same session between all parts of the app?

Answer 1

the middleware bundled with Connect are "self aware" in that they will not duplicate work they've already done. So for example if you have req.session already, and both the "root" app, and a mounted app utilize the session() middleware, the root app's session will work, and the other will be ignored. So it should work as-is.
