The Logger in Kawkab Kawkab

Introduction

Logging is an essential part of any application, as it helps track the system’s state and behavior. The Kawkab Kawkab framework provides a built-in logging system that allows you to log messages at multiple levels such as: info, warn, error, verbose, debug, and silly.

Using the Logging System

Importing

To start using the logging system in Kawkab Kawkab, you need to import log from the kawkab library:

import { log } from "kawkab";

Logging Messages

Logging a General Message

To log a message at a specific level, use the message function and specify the desired log level.

Example:

log.message('info', 'This is an informational message.');

Logging an Error Message

To log an error message, use the error method:

Example:

log.error('An error occurred in the system.');

Logging a Warning Message

To log a warning message, use the warn method:

Example:

log.warn('This is a warning message.');

Logging an Informational Message

To log an informational message, use the info method:

Example:

Logging a Detailed Message

To log a message with more details than an informational level, use the verbose method:

Example:

log.verbose('This message contains additional details.');

Logging a Debug Message

To log a debug message during development, use the debug method:

Example:

log.debug('This is a debugging message.');

Logging a Very Detailed Message

To log a message with the highest level of detail, use the silly method:

Example:

log.silly('This is a highly detailed message.');

Storing Logs

Log File

All logged messages are stored in a file named app.log.
This file contains all the logged events and can be used for reviewing logs and analyzing system performance.

Example of Log File Contents:

[2024-11-28T14:32:00.000Z] [INFO] - The application started successfully.
[2024-11-28T14:33:00.000Z] [ERROR] - An error occurred in the database.
