API Explanations with Code Snippets

Basic Logging

Zen-logger provides simple methods for standard logging levels.

 logger.info('This is an info message');
 logger.warn('This is a warning message');
 logger.error('This is an error message');

Custom Log Levels

Create custom log levels to better categorize your logs.

 logger.addLevel('debug', 1000);
 logger.debug('This is a debug message');

Logging with Metadata

Attach additional metadata to your log messages.

 logger.info('User login attempt', { userId: '12345', timestamp: new Date() });

Configurable Transports

Set up different transports to direct your logs to various destinations.

 logger.addTransport('file', { filename: 'app.log' });
 logger.addTransport('console', { level: 'warn' });

Asynchronous Logging

Ensure your logging operations do not block the main execution thread.

 logger.logAsync('info', 'This is an async log message');

 const express = require('express');
 const logger = require('zen-logger');

 app.use((req, res, next) => {
   logger.info(`Incoming request: ${req.method} ${req.url}`);
   next();
