aio-lib-core-logging
Node.js Logger module for use by the Adobe I/O SDK
Install
npm install @adobe/aio-lib-core-logging
Use
let aioLogger = require('@adobe/aio-lib-core-logging')('App')
aioLogger.info('Hello logs')
Output
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.
Configuration
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
Using custom logger
// 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'})
Send logs to a file
let aioLogger = require('@adobe/aio-lib-core-logging')('App', {transports: './logfile.txt' })
Custom winston transports
const winston = require('winston')
let aioLogger = require('@adobe/aio-lib-core-logging')('App', {transports: [new winston.transports.File({ filename: './winstoncustomfilelog.txt' })]})
Creating custom logger
This is currently as simple as creating a new logger class under src with all the log level functions defined
