Usage

Creating a logger and logging a message:

import { Logger, LogLevel } from '@xorgal/logger';

Set minimum log level:

const log = new Logger({ level: LogLevel.info });
log.info('Hello, Logger!');

Configuration:

const isDevelopment = process.env.NODE_ENV === 'development' ? true : false;

const log = new Logger({
  timestamp: true,
  level: isDevelopment ? LogLevel.debug : LogLevel.info,
  includeLevel: true,
  colorize: true,
  align: true,
});

log.debug('This is debug message.');

// Output:
// 2023-09-29T10:57:24.803Z [debug] This is debug message.

enum LogLevel {
    debug = 0,
    info = 1,
    warn = 2,
    error = 3
}
