Extending session object with util functions (e.g. accessors)

[jamil-naja-acn]

The data I am storing requires some safeguarding and additional pre-processing before the API handler kicks in.

This could be done by extending the session object with such functions that API handlers could use (instead of accessing the session data directly)

Whats the best way to do this without risking the additional function interfering with the serialisation of the session?

I can see defineMethod here: https://github.com/expressjs/session/blob/master/session/session.js#L136

If I follow the same approach; would it be safe not to interfere with the core framework / serialisation?

Thanks
