SCRU128: Sortable, Clock and Random number-based Unique identifier
SCRU128 ID is yet another attempt to supersede UUID in the use cases that need
decentralized, globally unique time-ordered identifiers. SCRU128 is inspired by
ULID and KSUID and has the following features:
- 128-bit unsigned integer type
- Sortable by generation time (as integer and as text)
- 26-digit case-insensitive portable textual representation
- 44-bit biased millisecond timestamp that ensures remaining life of 550 years
- Up to 268 million time-ordered but unpredictable unique IDs per millisecond
- 84-bit layered randomness for collision resistance
import { scru128, scru128String } from "scru128";
const x = scru128();
console.log(String(x));
console.log(BigInt(x.toHex()));
console.log(scru128String());
