bunyan

I have an embedded TypeScript system that must minimize writing to disk for integrity and has therefore been logging to console (all in RAM) with homespun log level filtering. Now, I need to keep the most recent N logs somewhere that the application can retrieve them, with levels/timestamps. bunyan has a RingBuffer that sounds like this, but I might be overlooking others that can do the same (including the other two tools for the diversity of input). Do you have a favorite logger you would use over Bunyan for some other reason, like performance or ease of integration?
