uuid

uuid creates v4 UUIDs.

Installation

$ npm install uuidv4

Quick start

First you need to integrate uuidv4 into your project by using the require function.

const uuid = require('uuidv4');

Then you can create UUIDs. To do so simply call the uuid function.

console.log(uuid());
// => '11bf5b37-e0b8-42e0-8dcf-dc8c4aefc000'

Verifying a UUID

To verify whether a given value is a UUID, use the is function.

console.log(uuid.is('75442486-0878-440c-9db1-a7006c25a39f'));
// => true

If you want to perform the verification on your own, use the regex property.

console.log(uuid.regex);

Getting a UUID from a string

From time to time you need an identifier that looks like a UUID, but is actually inferred from a string. For that, use the fromString function.

console.log(uuid.fromString('the native web'));
// => 'cc762e69-089e-4239-8b06-1ab26a005319'

Getting the empty UUID

If you need a UUID that consists only of zeros, use the empty function.

console.log(uuid.empty());
// => '00000000-0000-0000-0000-000000000000'
