Suggestions on best mongo-counter package to use?


searching for counter:
brings up a lot of choices…
3 of which are named mongo-counter and seem to have very similar descriptions… any experience with them in particular or suggestions on which to use?

I think I need to look into something like this because I am migrating from a database system that used incrementing numbers for record ids, and the users would like to keep those numbers in use, ie, they don’t want me to start showing them huge mongo ids !
