Package Exports

console-log-level

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (console-log-level) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

console-log-level

A dead simple logger. Will log to STDOUT or STDERR depending on the chosen log level. It uses console.info, console.warn and console.error and hence supports the same API.

Log levels supported: trace, debug, info, warn, error and fatal.

Installation

npm install console-log-level

Example usage

var log = require('console-log-level')({ level: 'info' })

log.trace('a') // will not do anything
log.debug('b') // will not do anything
log.info('c')  // will output 'c\n' on STDOUT
log.warn('d')  // will output 'd\n' on STDERR
log.error('e') // will output 'e\n' on STDERR
log.fatal('f') // will output 'f\n' on STDERR

Options

Configure the logger by passing an options object:

var log = require('console-log-level')({
  prefix: function () { return new Date().toISOString() },
  level: 'info'
})

level

A string to specify the log level. Defaults to info.

prefix

Specify this option if you want to set a prefix for all log messages. This must be a string or a function that returns a string.
