UUID & ULID generator

Generate UUID v4, time-ordered UUID v7 or ULIDs, in bulk, from a cryptographically secure source.

Time-ordered, RFC 9562. Sorts by creation time, keeps B-tree inserts sequential, and still carries 74 bits of randomness.

Generated locally with crypto.getRandomValues — a cryptographically secure source, not Math.random. Nothing is transmitted, so these are safe to use as real identifiers.
