SCRU128 ID is yet another attempt to supersede UUID for the users who need decentralized, globally unique time-ordered identifiers. SCRU128 is inspired by ULID and KSUID and has the following features:
import { scru128, scru128String } from "scru128";
// or on browsers:
// import { scru128, scru128String } from "https://unpkg.com/scru128@^3";
// generate a new identifier object
const x = scru128();
console.log(String(x)); // e.g., "036z951mhjikzik2gsl81gr7l"
console.log(x.toBigInt()); // as a 128-bit unsigned integer
// generate a textual representation directly
console.log(scru128String()); // e.g., "036z951mhzx67t63mq9xe6q0j"
See SCRU128 Specification for details.

v3.0.2 - 2023-07-17
Most notably, v3 switches the letter case of generated IDs from uppercase (e.g., "036Z951MHJIKZIK2GSL81GR7L") to lowercase (e.g., "036z951mhjikzik2gsl81gr7l"), though it is technically not supposed to break existing code because SCRU128 is a case-insensitive scheme. Other changes include the removal of deprecated APIs.
