Is it possible to just do(null, user) in the serializeUser/deserializeUser functions in passport.js?

Question

Node.js

Good evening.
Can serializeUser and deserializeUser just return user? Doing nothing with it?

passport.serializeUser(function(user, done) {
    done(null, user);
});
passport.deserializeUser(function(user, done) {
    done(null, user);
});

Answer 1

It is possible, but in theory you do not store the user'a object, but its identifier, by which in deserializeUser you request it from the source (for example, a database), then the data is relevant within the request
