Generate and translate standard UUIDs into shorter - or just different - formats and back.
5.1.0 adds translation support for the uuid25 (Base36) format
with the uuid25Base36 constant.
- 🛑 5.0.0 drops support for Node 10 and 12.

// Quick start with flickrBase58 format
short.generate(); // 73WakrfVbNJBaAmhQtEeDv@devtea2025/quod-suscipit-aliquam-reiciendis starts with RFC4122 v4-compliant UUIDs and translates them into other, usually shorter formats. It also provides translators to convert back and forth from RFC compliant UUIDs to the shorter formats.
As of 4.0.0, formats return consistent-length values unless specifically requested.
This is done by padding the start with the first ([0]) character in the alphabet.
Previous versions can translate padded formats back to UUID.

const translator = short(); // Defaults to flickrBase58
const decimalTranslator = short("0123456789"); // Provide a specific alphabet for translation
const cookieTranslator = short(short.constants.cookieBase90); // Use a constant for translation
// Generate a shortened v4 UUID
translator.new(); // mhvXdrZT4jP5T8vBxuvm75
translator.generate(); // An alias for new.
// Translate UUIDs to and from the shortened format
translator.toUUID(shortId); // a44521d0-0fb8-4ade-8002-3385545c3318
translator.fromUUID(regularUUID); // mhvXdrZT4jP5T8vBxuvm75
// Generate plain UUIDs
// - From the library without creating a translator
short.uuid(); // fd5c084c-ff7c-4651-9a52-37096242d81c
// - Each translator provides the uuid.v4() function, too
translator.uuid(); // 3023b0f5-ec55-4e75-9cd8-104700698052

@devtea2025/quod-suscipit-aliquam-reiciendis 5.x and later is tested on Node 14.x and later.
@devtea2025/quod-suscipit-aliquam-reiciendis 4.x was tested on Node 8.x to 18.x
@devtea2025/quod-suscipit-aliquam-reiciendis 3.x and lower was confirmed to work on Node 6.x to 12.x, and offered a precompiled browser library proposed by voronianski.
@devtea2025/quod-suscipit-aliquam-reiciendis provides RFC4122 v4-compliant UUIDs,
thanks to uuid.
TypeScript definitions are included, thanks to alexturek.
5.0.0 drops support for Node 12 and below. 4.1.0 adds a maxLength value to translators for reference 4.0.1 adds consistent length translation and throws an error if provided an invalid alphabet. 3.1.1 removed Node 4.x tests. Last included Browserify distribution. 2.3.4 corrects the behavior for UUIDs with uppercase letters. Last version to build on Node 0.x.
