UUID / ULID Generator
UUID (Universally Unique Identifier) is a 128-bit random ID such as 550e8400-e29b-41d4-a716-446655440000. ULID (Universally Unique Lexicographically Sortable Identifier) is a 26-character alternative whose timestamp prefix sorts by creation time. Generate either in bulk for fixtures, keys and tests.
UUID or ULID?
UUID v4 is random, ubiquitous and safe to generate anywhere, but it sorts arbitrarily — poor for index locality in a database. ULID starts with a millisecond timestamp, so newer rows sort after older ones while staying unique. Both here come from crypto.getRandomValues().
