Tagged-console-target NPM

TaggedConsoleTarget

A log target for Winston that expects tagged log messages and writes them with lots of colors to the console or a given output stream.

This module is designed to work together with TaggedLogger.

Install

npm install tagged-console-target

Example

For this example you need to npm install winston tagged-console-target.

var winston = require('winston');
var TaggedConsoleTarget = require('tagged-console-target');

var logger = new (winston.Logger)({
	transports: [
		new TaggedConsoleTarget()
	]
});

logger.info("Log message 1", {tags: ['module a']});
logger.info("Log message 2", {tags: ['module a', 'submodule a1']});
logger.info("Log message 3", {tags: ['module b']});

Example output:

16:46:06.004 2013-04-17 Wednesday
16:46:06.007 [module a] Log message 1
16:46:06.008 [module a, submodule a1] Log message 2
16:46:06.008 [module b] Log message 3

Except the output is in glorious color!

Options

TaggedConsoleTarget accepts an object with options for the constructor. The accepted options are:

target: The target output stream. Defaults to process.stdout
level: The minimum level of log messages to output to this logger, for example "info". Keep this unset to allow all messages that are accepted by the logger object
handleExceptions: Set to true to intercept unhandled exceptions and output them to this log target
exceptionsLevel: The log level at which to log exceptions. Defaults to error
humanReadableUnhandledException: Format exception log output in a more readable fashion
