Classes

Utils

The Utils class provides utility methods. Currently, it only has one static method:

• createGuid(): This method generates a random GUID using a combination of random numbers and a predefined pattern. It uses the crypto module to generate random bytes if available, otherwise it falls back to using Math.random().

                return (rands[0] % 16).toString(16)
            }

            return (Math.floor((Math.random() * 16))).toString(16)
        }
        return 'xxxxxxxx-xxxx-4xxx-8xxx-xxxxxxxxxxxx'.replace(/x/g, randomDigit)
