如何在nodejs中为应用程序全局保留每个请求的用户信息

Question

I am working on nodejs (expressjs) application. After authentication a random generated token is return to app. That token is used for authenticating further requests. After authenticating how do we keep user info till completing request. Can we use session?

Answer 1

Option 1 (as mentioned in comments)

You can store your user data manually in the request object req.user = userData

Option 2

Using an external library like passport.js allows you to handle the whole authentication part and automatically saves the authenticated user into the request object ( req.user ) for every single request (as long as the user authenticated)
