Log4js: logs depend on NODE_ENV

Question

How can I make logs (INFO, ERROR) dependent on set NODE_ENV?

I mean, for example, if NODE_ENV=development, I write only ERROR logs. With NODE_ENV=production, there has to be only INFO.

How should I modify appenders to perform this?

Thanks for your help.

I have found more appropriate (for me) solution of this problem. Just configure categories in levels in this way:

...
      "levels": {
        "[all]": "INFO",
        "console": (env == "production" ? "ERROR" :"INFO")
      },
...

I needed to think a little before rushing to stackoverflow :)
