Uncaught (in promise) cause process exit?

We do not handle reconnects currently.

It is not a matter of connection timeouts, but rather an error that does not catch and causes the program to exit.

well there is a darft PR about your issue atleast https://github.com/denodrivers/mongo/pull/401

For a workaround i would recommend using docker or systemd with auto restarts/health checks so if your connection drops out your service is not down
