What's a ULID?
A Universally unique Lexicographically sortable IDentifier (ULID), is an alternative uniquely generated identifier from the GUID, UUID, and KSUID. ULIDs are 128-bit text strings generated with 48 bits dependent with the current timestamp in milliseconds and 80 bits generate through randomness.
What are the benefits of using an ULID?
The most apparent benifit to choosing ULIDs as your unique identifier is that they are lexicographically sortable. Your stored items will automatically be sorted by timestamp when you use ULIDs. ULIDs are also URL safe since they do not use any special characters.
