amuyu / node-logger

Simple log for node

npmlog

This logger is very basic. It does the logging for node.
It supports custom levels and display of file name and function name and line number of output location.

Installation

npm install amuyu-logger --save

Basic Usage

var logger = require('amuyu-logger')

function test() {
// message -----------+                         
// level ---+         |                         
//          v         v                         
    logger.log('Hello world')
}
test()

example output:

// <fileName>: <functionName>(lineNumber) message
test.js: test(10) helloworld

log.level

• log.log(message, ...)
• log.info(message, ...)
• log.warn(message, ...)
• log.error(message, ...)

log.addLevel(level, n, style, disp)

Sets up a new level

• level {String} Level indicator
• style {Object} Object with fg, bg, inverse, etc.

var logger = require('amuyu-logger')

logger.addLevel('test', { fg: 'green', bg: 'black' })
logger.test('hello')

Style Objects

Style objects can have the following fields:

• fg {String} Color for the foreground text
• bg {String} Color for the background
• bold, inverse, underline {Boolean} Set the associated property
• bell {Boolean} Make a noise (This is pretty annoying, probably.)
