Function clearStatistics

Clear all statistics data and reset to default empty state

Completely erases all collected listening statistics and reinitializes the statistics store with empty default values. This function is typically used when the user wants to reset their listening history or when data integrity issues require a fresh start.

The function:

  • Creates a new default statistics object with the current timestamp
  • Ensures the target directory exists
  • Deletes all statistics files except the main one
  • Resets the main statistics file with default empty values
  • Triggers a manual aggregation to regenerate all statistics files
  • Handles any errors that occur during the reset operation

Example

// Reset all statistics
const success = await clearStatistics();
if (success) {
  showNotification("Statistics have been reset");
} else {
  showErrorMessage("Failed to reset statistics");
}
