Functions

Function	Description	Example
list	Get all stored logs	dphelper.log.list()
reg	Log regular message	dphelper.log.reg(message)
debug	Log debug message	dphelper.log.debug(message)
error	Log error message	dphelper.log.error(message)

Description

Application logging system:

• Multiple Levels - Regular, debug, and error logging

• Log Storage - Keep history of all logged messages

• Retrieval - Access logs anytime with list()

• Development - Useful for debugging and monitoring

Usage Examples

Basic Logging

// Regular log
dphelper.log.reg('Application started');
dphelper.log.reg('User logged in');

// Debug log
dphelper.log.debug('Variable value:', someVariable);
dphelper.log.debug('API Response:', response);

// Error log
dphelper.log.error('Failed to fetch data');
dphelper.log.error('Invalid input:', error);

Retrieve Logs

// Get all logs
const allLogs = dphelper.log.list();
// Returns array of all logged messages

// Display in console
console.table(dphelper.log.list());

// Filter by type
const logs = dphelper.log.list();
const errors = logs.filter(l => l.type === 'error');

Debugging Application

// Track function execution
function processData(data) {
  dphelper.log.debug('Processing started', data);

  try {
    const result = transform(data);
    dphelper.log.debug('Processing complete', result);
    return result;
  } catch (err) {
    dphelper.log.error('Processing failed', err);
    throw err;
  }
}

Error Tracking

// API error handling
async function fetchData(url) {
  try {
    const response = await fetch(url);
    dphelper.log.reg(`Fetched: ${url}`);
    return response.json();
  } catch (err) {
    dphelper.log.error(`Failed to fetch ${url}`, err);
    return null;
  }
}
