go-log

Classes

Logger - in your code, log messages at several different levels. Have the ability to change the logging level on the Logger instance so that only messages of certain importance are shown.

Quick start

Do npm install go-log in your Javascript npm project directory. Then in a Javascript file:

import { Logger } from 'go-log';

const defaultLog = new Logger();
defaultLog.success('You have successfully displayed a success-level message using go-log');

const logger7 = new Logger({
  level: 7,
  shy: false,
  hideLevel: false,
});
logger7.fatal('A fatal error');
logger7.error('An error');
logger7.warn('A warning');
logger7.success('A success');
logger7.info('An info');
logger7.debug('A debug');
logger7.trace('A trace');
logger7.debug({ text: 'Text can be supplied as an object' });
logger7.success({ obj: { or: 'you', can: 'directly log', any: 'object' } });
