simple-level-log

Super lightweight easy to use Javascript/Node.js module to write an applicaiton logs using varing level of detail. Like many other popular modules/packages log level can be set to as per your applicaiton need. However this module also allow you to selectively turn on or off each log method.

Getting Started

These instructions will get you a copy of the project up and running on your local machine for development and testing purposes. See deployment for notes on how to deploy the project on a live system.

Prerequisites

None

Installing

npm i simple-level-log

Please see index.js for additional examples.

Example-1: Print status of loging methods.

const logger = require('simple-level-log/logger');
logger.logStatus()


Output:

Test: Stated.
isVerboseOn: true
isTraceOn: true
isDebugOn: true
isInfoOn: true
isWarnOn: true
isErrorOn: true
Test: Finished.

Example-2: Set level to INFO so that INFO, WARN, ERROR will be active. Turn on lower ranking methods like verbose. Notice that debug and trace methods in effect.

const logger = require('simple-level-log/logger');

function testLogger() {
    logger.verbose('This is a verbose message');
    logger.trace('This is a trace message');
    logger.debug('This is a debug message');
    logger.info('This is an info message');
    logger.warn('This is a warn message');
    logger.error(new Error('This is an error message'));
}

console.log('Test: Stated.');
logger.setAllOff();
logger.setLeve(logger.Leveles.INFO);
logger.isVerboseOn = true;
testLogger();
console.log('Test: Finished.');


Output:

Test: Stated.
[v]: This is a verbose message
[i]: This is an info message
[w]: This is a warn message
[e]: Error: This is an error message
Error: This is an error message
