The memory session storage is a built-in storage adapter that saves your session data in RAM using a regular JavaScript Map object. If you use this storage adapter, all sessions will be lost when your process terminates or restarts. Hence, you should only use it for short-lived data that is not important to persist.

This class is used as default if you do not provide a storage adapter, e.g. to your database.

This storage adapter features expiring sessions. When instatiating this class yourself, you can pass a time to live in milliseconds that will be used for each session object. If a session for a user expired, the session data will be discarded on its first read, and a fresh session object as returned by the inital option (or undefined) will be put into place.
