UUIDv7 Generator

uuidv7 is a JavaScript library providing a robust implementation of Universally Unique Identifiers (UUID) version 7, as defined by RFC 9562. UUIDv7 introduces a time-ordered component, making the generated IDs monotonically increasing and thus highly suitable for database primary keys or indexed fields where sequential writes and improved locality are beneficial, unlike traditional UUIDv4. The current stable version is 1.2.1. It also includes support for UUIDv4 generation and offers an object representation for UUIDs, allowing programmatic inspection and comparison. The library is designed to handle clock rollbacks and counter overflows gracefully to maintain monotonicity, with a large 42-bit counter and mechanisms to increment the internal timestamp if the counter overflows within a millisecond.
