guid-factory

guid-factory

Provides GUIDs via a Guid factory class and supporting guid TypeScript typing.

Unlike similar typescript GUID/UUID libraries, all generated values exist as strings at run time, but still are able to be strongly-typed at build time due to the typescript flavoring.

The benefit is that the guid typing needn't be instantiated as a new object, which plays nicer with server supplied values, as serialization/parsing from json isn't required.

Installation

npm i guid-factory

Usage

Import or require guid and Guid from 'guid-factory'

import { guid, Guid } from 'guid-factory'; // guid is the type, Guid is the factory

const myId: guid = Guid.newGuid();

const isValid = Guid.isValid(myId);

'00000000-0000-0000-0000-000000000000' === Guid.empty() // true
