Installation

npm install @onurege3467/live-logger

Usage

As a module in your Node.js/Express application

const { logger } = require('@onurege3467/live-logger');

// Start the logger server
logger.start();

// Log messages
logger.info('Server started');
logger.warn('Warning message');
logger.error('Error occurred');
logger.debug('Debug information');

As a CLI tool to capture shell script logs

# Install globally
npm install -g @onurege3467/live-logger

# Run your script and pipe the output to live-logger
your-script.sh | live-logger

# Or directly use it with a command
live-logger "npm start"

• Clear logs
• Pause/resume log streaming
