  logError: true,
}); // will output an error using console.error if myFile is not found

tryRequire('./myFile', {
  errorMessage: 'Custom error message',
}); // will throw a custom error message if myFile is not found

tryRequire('./myFile', {
  errorMessage: (path: string, error?: Error): string => `Custom error with ${path} and ${error.message}`,
