transformId() should allow asynchronous computations

See original GitHub issue

I use transformId() to apply a cryptographic hash to the session id, which is very cpu-heavy and should be done asynchronously. It would be great if instead of the value itself transformId() could also return a Promise with the generated value.

I have implemented this in my fork as https://github.com/nikwen/connect-mongo/commit/18f01604fad6e7509da20a8557a3b78464ef11ec, but the implementation uses async/await, so it would break compatibility for Node versions <8.

@nikwen thanks for the update, however @mingchuno is the maintainer. I just commented on an issue that doesn’t apply to the connect-mongo session store, and is more suitably implemented using existing API methods in express.

@mingchuno no, not related. The uniqueness of the session id, coupled with the probability of a value being used more than once, is a separate issue than encryption of the session data.
