Viewing Logs

Console stores all logs in memory, allowing you to inspect them later.

Using viewLogs()

The viewLogs() method displays logs in batches using console.table:

const logger = new Konsole({ namespace: 'App' });

// Log some messages
logger.log('Message 1');
logger.log('Message 2');
logger.log('Message 3');
// ... many more logs

// View first 100 logs (default batch size)
logger.viewLogs();

// Call again to see the next batch
logger.viewLogs();

// Custom batch size
logger.viewLogs(50);

Resetting the Batch

When you reach the end of logs, calling viewLogs() will reset automatically:

logger.viewLogs(); // Shows logs 1-100
logger.viewLogs(); // Shows logs 101-200
logger.viewLogs(); // "End of logs. Call viewLogs() again to restart."
logger.viewLogs(); // Shows logs 1-100 again

// Manually reset
logger.resetBatch();

Programmatic Access

Get all logs as an array:

const logs = logger.getLogs();

// Filter logs
const errors = logs.filter(log => log.logtype === 'error');
const recent = logs.filter(log => 
  log.timestamp > new Date(Date.now() - 3600000)
);

// Export to JSON
const json = JSON.stringify(logs, null, 2);

Clearing Logs

Remove all stored logs:

logger.clearLogs();

Log Retention

By default, logs older than 48 hours are automatically removed. Customize this:

const logger = new Konsole({
  namespace: 'App',
  retentionPeriod: 24 * 60 * 60 * 1000, // 24 hours
  cleanupInterval: 30 * 60 * 1000,      // Check every 30 minutes
});

Configuration

Option	Default	Description
defaultBatchSize	100	Number of logs per viewLogs() call
retentionPeriod	48 hours	How long to keep logs
cleanupInterval	1 hour	How often to clean old logs
