A noop logger that conforms to the Log4j interface for modules to stub out internal logging
npm install abstract-loggingThis module provides an interface for modules to include so that they can
support logging via an external logger that conforms to the standard Log4j
interface. One such logger is Pino. This module
is intended for modules that are meant to be used by other modules.
Example:
``js
'use strict'
function AwesomeLibrary (options) {
this.log = (options.logger) ? options.logger : require('abstract-logging')
}
AwesomeLibrary.prototype.coolMethod = function () {
this.log.trace('AwesomeLibrary.coolMethod was invoked')
return {}
}
module.exports = AwesomeLibrary
`
Available methods:
+ fatal
+
+
+
+
+
All methods are no operation functions.
Some loggers, like Pino, implement a child() method. This method can be easily added to an abstract-logging instance when stubbing out such loggers:
`js``
const logger = require('abstract-logging')
logger.child = () => logger
