API

createLogger(options?)

Creates a new logger instance.

Options:

• level: Minimum log level ('debug' | 'info' | 'warn' | 'error')
• timestamp: Include timestamps in output (default: false)

Methods:

• debug(...args): Debug level (gray)
• info(...args): Info level (blue)
• warn(...args): Warning level (yellow)
• error(...args): Error level (red)

Log Levels

Levels in order of severity:

1. debug - Detailed debugging information
2. info - General informational messages
3. warn - Warning messages
4. error - Error messages

Setting a minimum level filters out lower-priority messages.

Examples

// Production logger (only warnings and errors)
const prodLogger = createLogger({ level: 'warn' });

// Development logger (all messages)
const devLogger = createLogger({ level: 'debug', timestamp: true });

// Simple usage
devLogger.info('Server started on port', 3000);
devLogger.error('Failed to connect:', error);
