Uuid25: 25-digit case-insensitive UUID encoding

Uuid25 is an alternative UUID representation that shortens a UUID string to just 25 digits using the case-insensitive Base36 encoding. This library provides functionality to convert from the conventional UUID formats to Uuid25 and vice versa.

import { Uuid25 } from "uuid25";

// convert from/to string
const a = Uuid25.parse("8da942a4-1fbe-4ca6-852c-95c473229c7d");
console.assert(a.value === "8dx554y5rzerz1syhqsvsdw8t");
console.assert(a.toHyphenated() === "8da942a4-1fbe-4ca6-852c-95c473229c7d");

// convert from/to 128-bit byte array
const b = Uuid25.fromBytes(new Uint8Array(16).fill(0xff));
console.assert(b.value === "f5lxx1zz5pnorynqglhzmsp33");
console.assert(b.toBytes().every((x) => x === 0xff));

// convert from/to other popular textual representations
const c = [
  Uuid25.parse("e7a1d63b711744238988afcf12161878"),
  Uuid25.parse("e7a1d63b-7117-4423-8988-afcf12161878"),
  Uuid25.parse("{e7a1d63b-7117-4423-8988-afcf12161878}"),
  Uuid25.parse("urn:uuid:e7a1d63b-7117-4423-8988-afcf12161878"),
];
console.assert(c.every((x) => x.value === "dpoadk8izg9y4tte7vy1xt94o"));

const d = Uuid25.parse("dpoadk8izg9y4tte7vy1xt94o");
console.assert(d.toHex() === "e7a1d63b711744238988afcf12161878");
console.assert(d.toHyphenated() === "e7a1d63b-7117-4423-8988-afcf12161878");
console.assert(d.toBraced() === "{e7a1d63b-7117-4423-8988-afcf12161878}");
console.assert(d.toUrn() === "urn:uuid:e7a1d63b-7117-4423-8988-afcf12161878");
