How can I attach a function to run on response in express?

so I want saveSession to run when response begins, basically at the
end of the script.

Is there an easy way of doing this?

I know the built in session class does this but I can't use that since
my sessions are quite customised and need some special functions and
behaviour that meant writing a new class was easier.
