A simple library to generate binary UUIDv7s and ULIDs.

Usage

const { ULID, UUIDv7, ULIDMonotonicFactory } = require('@control/uulid');

const ulid = new ULID();
const ulid_human = ulid.toString();
const ulid_bytes = ulid.bytes;
const other_ulid_bytes = ULID.generate();

const uuidv7 = new UUIDv7();
const uuidv7_bytes = uuidv7.bytes;
const other_uuidv7_bytes = UUIDv7.generate();

Spec

Fully compliant with specs:

• UUID v7: https://www.rfc-editor.org/rfc/rfc9562.html#name-uuid-version-7
• ULID: https://github.com/ulid/spec

Next steps

• Implement in Rust with JS bindings for performance
• Unroll quintets manually to prevent byte loops
