seems you're missing something ... here's an example

// utilities/logger.js


const SimpleNodeLogger = require('simple-node-logger');
const opts = {
    logFilePath:'mylogfile.log',
    timestampFormat:'YYYY-MM-DD HH:mm:ss.SSS'
};

const log = SimpleNodeLogger.createSimpleLogger(opts);

module.exports = log;

and then, just use it

// index.js

const logger = require('./utilities/logger');


logger.info(`I'm an information line`);
logger.debug(`I'm a debug line`);
logger.error(`I'm an error line`);

that will output in a new created file called mylogfile.log:

2020-12-25 13:37:17.139 INFO  I'm an information line 
2020-12-25 13:37:17.140 ERROR I'm an error line

set the log level if you want to output more info, like debug. All options are in the package page titled "How to use"
