Provides a simple module with a log() function and a logLevel value. The log() function writes the msg to stdout, prefixed with a timestamp, if the logLevel is greater than or equal to the number in the first argument.
npm install log5
log5 = require("log5")
log5.logLevel = 2
log(2, "This prints")
log(3, "This doesn't")
You are free to make up whatever level numbers you want, and assign what ever meaning to them that you want.
It's very simple, and gets the job done, and allows you to change the log output at runtime if you like, by just changing the logLevel.
log5 = require("log5") // log level defaults to 0
log = log5.log // for convenience
log(1, "does not print") // because logLevel is 0
log(1) // same as log5.logLevel = 1
log(1, "prints")
log(-1) // sure, why not?
log(0, "does not print")
log("does not print") // if you don't include a # as first arg, 0 is used
log(0)
log("prints now")
log("foo", 7, ["bar","baz"]) // logs "foo 7 bar,baz"
log(3, "foo", 7, ["bar","baz"]) // does not print - logLevel is 0
