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.
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!
'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')
'use strict'
// dinamically 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')
