underscore.logger

Cross-browser and Node.js empowered logging.

Install

npm install underscore.logger

Browser

<script src="/javascripts/underscore.logger.js" type="text/javascript"></script>

Node.js

_console = require('underscore.logger')

If you want to make it useable everywhere in node:

global._console ||= require('underscore.logger')

Underscore Mixin

_.mixin require('underscore.logger').toObject() # _.mixin(_console.toObject())
_.log "It works!"
_.error "Log %s in RED", "something"

Api

# set the log level so anything above this won't show up
_console.level  = _console.constructor.DEBUG

# you can access the constructor helpers like this as well:
Logger          = _console.constructor
_console.level  = Logger.DEBUG

# override default colors for any of the log levels
_console.colors[Logger.WARN] = Logger.ANSI.RED

# the first parameter is the message, any following parameters are variables.
_console.trace  "I'm a trace"
_console.debug  "Debug message"
_console.info   "%s %s!", "Hello", "World" #=> "Hello World!"
_console.error  "ERROR!"
_console.fatal  "oh man..."

# set a custom `out` method, which defaults to `console.log`
_console.out    = (message) -> alert(message)

# customize the format too if you'd like, which defaults to `[date] level message`
_console.format = (date, level, message) -> message

# watch the fps to see how your app is performing (`this` is the `Logger.Timer` object)
_console.on "frame" ->
  $("#log-line-template").tmpl(@fps).appendTo("#log-panel")

To create a new one, maybe because you want two separate loggers (the edge case), you can use the constructor:

myLogger = new _console.constructor
