console-logfmt v3.0.2

console-logfmt

Wrap around logfmt exposing a interface compatible with console.log(), console.warn() and console.error().

Instalation

npm install console-logfmt

Usage

The level is defined as:

• log() ⇒ 'info'
• warn() ⇒ 'warn'
• error() ⇒ 'error'

Any string parameter will be concatenated to the msg= key:

const ConsoleLogFmt = require('console-logfmt')
const { log, warn, error } = new ConsoleLogFmt()

log('message')
// output:
// level=info msg=message

log('message', 'of something')
// output:
// level=info msg="message of something"

Any object parameter wil be passed to the logfmt as it is:

warn('message of warning', { extra: 'data' })
// output
// level=warn msg="message of warning" extra=data

error({ other: 'message of error', extra: 'data' })
// output
// level=error other="message of error" extra=data

Important to notice

The default output for any log level is the process.stderr, if you need something different, the console parameters still valid to be informed/replaced.
