How do I generate a random unique ID?

Is there a shorter version of UUID?

short-uuid starts with RFC4122 v4-compliant UUIDs and translates them into other, usually shorter formats. It also provides translators to convert back and forth from RFC compliant UUIDs to the shorter formats. As of 4.0. 0, formats return consistent-length values unless specifically requested.

How long should a unique ID be?

Universally Unique Identifiers, or UUIDS, are 128 bit numbers, composed of 16 octets and represented as 32 base-16 characters, that can be used to identify information across a computer system. This specification was originally created by Microsoft and standardized by both the IETF and ITU.

What is unique ID example?
