UUID.js is a JavaScript/ECMAScript library to generate RFC 9562 compliant Universally Unique IDentifiers (UUIDs). This library supports UUIDv4 (random number-based UUIDs), UUIDv1 (Gregorian time-based UUIDs), and UUIDv6 (Reordered Gregorian time-based UUIDs). It also provides an object-oriented interface to print a generated or parsed UUID in a variety of forms.
Math.random()
otherwiseImport UUID
class:
import { UUID } from "uuidjs";
// or on browsers:
// import { UUID } from "https://unpkg.com/uuidjs@^5";
UUID.generate()
returns a UUIDv4 as a hexadecimal string.
// Create a UUIDv4 as a hexadecimal string
console.log(UUID.generate()); // fa84cf42-ffdf-4975-b42b-31ab5fb983eb
UUID.genV4()
, UUID.genV1()
, UUID.genV6()
, and UUID.parse()
return a UUID
object that has various fields and methods.
// Create a UUIDv4 (random number-based UUID) object
const objV4 = UUID.genV4();
// Create a UUIDv1 (Gregorian time-based UUID) object
const objV1 = UUID.genV1();
// Create a UUIDv6 (Reordered Gregorian time-based UUID) object
const objV6 = UUID.genV6();
// Create a UUID object from a hexadecimal string
const uuid = UUID.parse("a0e0f130-8c21-11df-92d9-95795a3bcd40");
// Get string representations of a UUID object
console.log(uuid.toString()); // "a0e0f130-8c21-11df-92d9-95795a3bcd40"
console.log(uuid.hexString); // "a0e0f130-8c21-11df-92d9-95795a3bcd40"
console.log(uuid.hexNoDelim); // "a0e0f1308c2111df92d995795a3bcd40"
console.log(uuid.bitString); // "101000001110000 ... 1100110101000000"
console.log(uuid.urn); // "urn:uuid:a0e0f130-8c21-11df-92d9-95795a3bcd40"
// Compare UUID objects
console.log(objV4.equals(objV1)); // false
// Get UUID version numbers
console.log(objV4.version); // 4
console.log(objV1.version); // 1
console.log(objV6.version); // 6
