I feel like this has to be buried somewhere in the documentation, but I can't find it.
How do you close or end or kill (whatever) a session in ExpressJS?

Session handling is no longer built into Express. This answer refers to the standard session module:
To clear the session data, simply use:
req.session.destroy();
The documentation is a bit useless on this. It says:
Destroys the session, removing req.session, will be re-generated next request.
req.session.destroy(function(err) { // cannot access session here })
This does not mean that the current session will be re-loaded on the next request. It means that a clean empty session will be created in your session store on next request. (Presumably the session ID isn't changing, but I have not tested that.)
Never mind, it's req.session.destroy();
The question didn't clarify what type of session store was being used. Both answers seem to be correct.
For cookie based sessions:
From
req.session = null // Deletes the cookie.
For Redis, etc based sessions:
req.session.destroy // Deletes the session in the database.
From
To clear a cookie simply assign the session to null before responding:
req.session = null
