npm install @adobe/aio-lib-core-logging

let aioLogger = require('@adobe/aio-lib-core-logging')('App')
aioLogger.info('Hello logs')

Above code will log the following

[App /mynamespace/myaction] info: Hello logs

Where App would be the name of the application/module that is sending the logs.

The logger can be customized by passing a config object at the time of creation.

let aioLogger = require('@adobe/aio-lib-core-logging')('App', config)

The config object can have one or more of the following keys.

• level (max severity logging level to be logged. can be one of error, warn, info, verbose, debug, silly)
• provider (logging provider. default is winston.)
• logSourceAction (boolean to control whether to include the action name in the log message)
• transports (array of custom winston transports)

The log level can also be overridden using the env variable AIO_LOG_LEVEL

// Winston Logger
let aioLogger = require('@adobe/aio-lib-core-logging')('App', {provider:'winston'})
aioLogger.info('Hello logs')

or

// Debug Logger
let aioLogger = require('@adobe/aio-lib-core-logging')('App', {provider:'debug'})

let aioLogger = require('@adobe/aio-lib-core-logging')('App', {transports: './logfile.txt' })

const winston = require('winston')
let aioLogger = require('@adobe/aio-lib-core-logging')('App', {transports: [new winston.transports.File({ filename: './winstoncustomfilelog.txt' })]})

This is currently as simple as creating a new logger class under src with all the log level functions defined
