The pino-caller from roycrxtw

pino-caller's Introduction

pino-caller

Description

pino-caller is a wrapper for pino which adds the call site of each log message to the log output. This can be useful when developing with large codebases in order to locate the exact point where pino is invoked.

Install

For Pino v4 and below use the v2 line, which can be installed with the @legacy tag:

npm install pino-caller@legacy

For Pino v5 and above use the v3+ line, which will install using the usual command:

npm install pino-caller

WARNING: THIS IS A DEVELOPMENT TOOL AVOID PRODUCTION USE!

Usage

Basic

'use strict'

const pino = require('pino')() // it will print as usual
const pinoCaller = require('pino-caller')(pino) // it will print also the calling site

pinoCaller.info('info1')
pinoCaller.error('error1')
pinoCaller.debug('debug1')

Advanced

'use strict'
// dynamically load the plugin if in development environment
const pino = process.env.NODE_ENV === 'development' ? require('pino-caller')(require('pino')()) : require('pino')()

pino.info('info1')
pino.error('error1')
pino.debug('debug1')

You can find also a working example in the examples directory and you can run it with npm run example
