This is a straight up manual transpilation to ES6 of the short-uid npm package by Ankit Kuwadekar.

The above linked repository has gone stale, no updates in the past 3 years (as of updating this README).

If used in a ES6 environment it fails to follow good import standards.

Even so, the functionality is still useful. So here we are.

Install using npm:

npm install --save short-unique-id

ES6:

// Import
import ShortUniqueId from 'short-unique-id';

// Instantiate
const uid = new ShortUniqueId();

Node.js:

// Import
var ShortUniqueId = require('short-unique-id');

// Instantiate
var uid = new ShortUniqueId();

Browser:

<!-- Import -->
<script src="https://rawgit.com/jeanlescure/short-unique-id/master/dist/short-unique-id.min.js"></script>

<!-- Instantiate -->
<script>
  var uid = new ShortUniqueId();
</script>

Once instantiated you can use one of two functions:

// Generate Random Unique ID of a specific length
uid.randomUUID(6); // zUvMF8
uid.randomUUID(8); // 4308OPWZ
uid.randomUUID(13); // o0Sf6rfoPOrz5

// Generate Sequential Unique ID based on internal dictionary and counter
uid.sequentialUUID(); // v
uid.sequentialUUID(); // 0
uid.sequentialUUID(); // Y

Tests run using Jasmine:

npm test

This will update the short-unique-id.js file under ./lib, which will then be imported by the spec and tested.

Find lint using airbnb for eslint:

npm run lint

In order to publish the latest changes you must build the distribution files:

npm run build

This will update the short-unique-id.js file under ./lib, which will then be minified as the short-unique-id.min.js file under the ./dist directory.
