A simple and light weight logger

Getting started

Install

Use

Logger class

const {Logger, LogLevel} = require('@desouza-engineering/logger');

const logger = new Logger('issuername', LogLevel.LOG);

logger.critical('testing ctitical logger');
logger.error('testing error logger');
logger.log('testing default logger');
logger.info('testing info logger');
logger.debug('testing debug logger');
logger.trace('testing trace logger');

logger.logC('testing ctitical logger');

Using the builder

The builder allows you to set the logging level of the application in one place and create new loggers whenever needed.

Ideal usage would be to have a config file that exports the builder then import that builder wherever you need it and get a new logger.

const {LogLevel, LoggerBuilder} = require('@desouza-engineering/logger');

const builder = new LoggerBuilder(LogLevel.LOG);

const logger = builder.getLogger('issuername');

logger.critical('testing ctitical logger');
logger.error('testing error logger');
logger.log('testing default logger');
logger.info('testing info logger');
logger.debug('testing debug logger');
logger.trace('testing trace logger');

//[CRITICAL Sun Sep 22 2019 22:13:24 GMT-0500 issuername] testing critical logger
//[ERROR Sun Sep 22 2019 22:13:24 GMT-0500 issuername] testing error logger
//[LOG Sun Sep 22 2019 22:13:24 GMT-0500 issuername] testing default logger
