Discussion on: Why should your Node.js application not handle log routing?

I would definitely use a function, since you will need to timestamp and tag your logs, log structured data, etc.

And what if you want to extract part of the application into an internal library?Libraries shouldn't touch IO, they can only accept a logger injection.

And what if you want to use the code in a frontend web application? Who will route your logs there?

So yeah, always use a function/library, just don't try to connect to the logging server instead of stdout yourself, especially in a stateless deployment.
