Logger

Getting Started

These instructions will get you a copy of the project up and running on your local machine.

Installing

Simply execute npm i @vbattu/logger or if you use yarn yarn add @vbattu/logger

Quick Start

const Logger = require('@vbattu/logger');
const logger = Logger.getLogger('myFileName');
logger.info('My awesome log');

This will produce the following output: [2019-3-13 19:35:16] [INFO] [myFileName] - My awesome log'

You are free to pass a class to your logger:

class MyAwesomeClass {};
const logger = Logger.getLogger(MyAwesomeClass);
logger.info('My awesome log');

The following levels are available (ASC severity):

• Trace
• Debug
• Info
• Warn
• Error

The default logger level is Debug. You have to configure your logger object to display lower severity (Trace) :

const logger = Logger.getLogger('myLogger');
logger.level = Level.Trace;
