## What it is
A zero-dependency JavaScript/TypeScript library for generating and working with RFC9562 (formerly RFC4122) UUIDs, supporting all UUID versions including timestamp-based v6 and v7. It runs across Node.js, browsers, and React Native, and also ships a small CLI utility.

## Use cases
- generate random uuid v4 in javascript
- create timestamp-ordered uuid v7 for database keys
- generate uuids in react native or expo
- validate and detect version of a uuid string
- generate namespace-based uuid v5 from a name
- convert uuid v1 to v6
- generate uuids from the command line

## When to choose
- you need RFC-compliant UUID generation in JavaScript or TypeScript
- you need all UUID versions including v6 and v7
- you need a cross-platform solution (Node, browser, React Native)
- you want a zero-dependency, tree-shakable package

## When to avoid
- your runtime only supports CommonJS and you cannot migrate to ESM (uuid@12+ dropped CommonJS)
- you need UUIDs in a non-JavaScript language
- you need non-RFC custom identifier formats

## Facets
- artifact type: library
- maturity: stable
- function: serialization, developer-tools, cli
- domain: developer-tools, web-development, cross-platform
- platform: browser, cross-platform, cli
- tags: uuid, guid, rfc9562, rfc4122, typescript, zero-dependency, tree-shakable, nodejs
