API

log

A logger is exported. To use:

const log = require('kittie')
log.silly('hello')
log.verbose('hello')
log.info('hello')
log.http('hello')
log.warn('hello')
log.error('hello')

// to change the log level
log.level = 'silly'

// we also support child loggers
const debug = log.child('debug')
debug.level = process.env.DEBUG
  ? 'silent'
  : 'silly'

debug.info('Hey! This is a debug message')

Each logger has the following methods:

silly(message, meta)

message <String>
meta <Object>

Will only be logged if the logger's level is set to silly.

verbose(message, meta)

message <String>
meta <Object>

Will only be logged if the logger's level is set to silly or verbose.

info(message, meta)

message <String>
meta <Object>

Will only be logged if the logger's level is set to silly, verbose, or info.

http(message, meta)

message <String>
meta <Object>

Will only be logged if the logger's level is set to silly, verbose, info, or http.

warn(message, meta)

message <String>
meta <Object>

Will be logged unless the logger's level is set to silent or error.

error(message, meta)

message <String>
meta <Object>

Will be logged unless the logger's level is set to silent.

inspect(obj, depth)

log.inspect() is a bit different than the other log methods. It functions at the verbose log level, but calls util.inspect() under the hood.

child(component)

Creates a new child logger that inherits settings from it's parent. A child logger can be used to distinguish different modules inside a single project.
