Using simple-node-logger without momentjs

You've created a minimal project that uses simple-node-logger, simple multi-level logger for console and files:

// index.js
const SimpleLogger = require('simple-node-logger');
const appender = new SimpleLogger.appenders.ConsoleAppender();

const manager = new SimpleLogger();
manager.addAppender(appender);

const log = manager.createLogger();
log.info('this is a simplelog statement');

Check the size of bundle (~383 kb)

esbuild index.js --bundle --platform=node --outfile=index.dist.js

  index.dist.js  383.7kb

Removing momentjs

Change timestamp format code to remove the momentjs dependency:

// 
appender.formatter = function(entry) {
    const fields = this.formatEntry( entry, appender);

    return fields.join( appender.separator );
};
appender.formatTimestamp = (ts) => {
    return ts.toString();
};

And override it in package.json

{
  "dependencies": {
    "simple-node-logger": "^21.8.12"
  },
  "overrides": {
    "moment": "npm:dry-uninstall"
  }
}

Check the size of bundle (~241 kb)

esbuild index.js --bundle --platform=node --outfile=index.dist.js

  index.dist.js  241.7kb

Saved around 140 kb, not bad.
