abstract-logging

abstract-logging

This 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:

'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

Interface

Available methods:

• fatal
• error
• warn
• info
• debug
• trace

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:

const logger = require('abstract-logging')
logger.child = () => logger

Similar packages

Other packages similar to abstract-logging

noop-logger

The noop-logger package provides a similar functionality to abstract-logging by offering a logger with no-op methods. It can be used to silently ignore all logging operations.

bunyan-blackhole

Bunyan-blackhole is another package that provides a no-op logger, specifically designed to work with the Bunyan logging library. It is similar to abstract-logging but tailored for Bunyan's API.

pino-noir

Pino-noir is not a no-op logger but offers a feature to redact certain log fields. It is related to abstract-logging in the sense that it can be used to control the output of logs, although it serves a different purpose by focusing on privacy and security rather than completely disabling logging.
