BleedingTea - Node Logging

A tiny logging lib.

###Features

• Send log messages to multiple appenders. Featured as of v0.3.0
  • Console Appender: Send output to stdin
  • File Appender: Send output to a file
• Easy to use API inspired by well known Frameworks like LogBack
• Extend BleedingTea with custom Appender.
• Create your own logging functions that write output with custom label

// create new logger instance
var logger = new Logger()

// Create new function to output stuff under custom label
logger.label = Logger.createLogFunction(logger, "LABEL")

// use first class function
logger.label("This thing is custom-labeled")

==> [LABEL] This thing is custom-labeled

Usage

Basic usage. Write to stdin. Errors are written to stderr

var Logger = require("bleedingtea")

var log = new Logger() // Instance comes with ConsoleAppender
log.info("message")
log.error("message")
log.warning("message")

Send Messages To File

var Logger = require("bleedingtea")

var log = new Logger() // Instance comes with ConsoleAppender
log.addAppender(new Logger.appenders.FileAppender("log.log"))

Adding an initial new appender will remove the console appender. If aou wish to write to consle too, do log.addAppender(new Logger.appender.ConsoleAppender())

Create New Appenders

Creating new appenders is just a matter of creating an object with the following interface write(message), where message is a string containing the formatted log message ready to consume. See the built in appenders for working examples

Message Formatting

BleedingTea uses printf-style formatting to prettify your log messages. You can format your message by modifying the messageFormat field of your logger instance. Out of the box, the logger will your message prepended with the log level and a timestamp. This three components are currently available via format strings

Format String | Description ------------- | ----------- l | The loglevel d | The current date as timestamp m | The message passed by the client
