LogLevel

Type import for log level enum values (Trace, Debug, Info, Warn, Error, Fatal).

LoggerConfig

✓ import type { LoggerConfig } from 'styled-text-logger'

✗ import { LoggerConfig } from 'styled-text-logger'

✓ import { setLogLevel } from 'styled-text-logger'

Function to change the global log level at runtime.

Demonstrates basic info logging, error logging with exception, and debug logging with metadata object.

import { logger } from 'styled-text-logger'; logger.info('Application started'); try { // ... some code throw new Error('Sample error'); } catch (err) { logger.error('An error occurred', err); } logger.debug('Debug info', { user: 'alice', action: 'login' });
