UUID

In order to create a unique identifier, it's common to use a UUID (Universally Unique Identifier). This package generates a version 4 UUID compliant with RFC 4122 standards using pure JavaScript. The codebase for this project is inspired by the collective wisdom of the StackOverflow community.

_{New in version v2.1.0: Added an option to use cryptographic randomness via the Web Crypto API, enhancing the randomness quality of UUIDs where supported. This feature is optional and can be enabled during UUID generation.}

Demo

Check out the working demo on CodeSandbox:

How it works?

To install the package, run the following command:

npm i @smakss/uuid
# or
yarn add @smakss/uuid

For CommonJS modules, include it like this:

const uuid = require('@smakss/uuid');

For ECMAScript modules, import it as follows:

import uuid from '@smakss/uuid';

Then, you can use it within your application like this:

// Generate a new UUID using pseudo-random numbers
const uniqueID = uuid();
console.log(uniqueID); // Outputs: '123e4567-e89b-12d3-a456-426614174000' (example output)

// Generate a new UUID using cryptographic randomness (if supported)
const cryptoID = uuid(true);
console.log(cryptoID); // Outputs a UUID generated with cryptographic randomness

_{NOTE: Each call to uuid() generates a unique UUID, so the output will vary with each call. The cryptographic randomness option enhances the unpredictability of UUIDs in environments that support the Web Crypto API.}
