Error Handling

Handle Device Identification errors, timeouts, rate limits, and edge cases. Includes error codes, retry strategies, and fallback patterns.

Error Handling

Handle errors gracefully in production to prevent silent failures.

try {
  const result = await tc.get();
  console.log(result.visitorId);
} catch (error) {
  if (error.message === 'timeout') {
    // Collection took too long — retry or use fallback
    console.warn('Signal collection timed out');
  } else if (error.message === 'network') {
    // Network error — API unreachable
    console.error('API connection failed');
  } else {
    // Unknown error
    console.error('Identification failed:', error);
  }
}
