## Using IdGenie from a CDN

[IdGenie is available on jsDelivr](https://www.jsdelivr.com/package/npm/idgenie) and [unpkg](https://unpkg.com/browse/idgenie/), so you can use it directly in the browser without installing via npm. Just include the script, and `idgenie` will be available globally:

```html
<!-- Latest version -->
<script src="https://cdn.jsdelivr.net/npm/idgenie/dist/idgenie.umd.min.js"></script> or
<script src="https://unpkg.com/idgenie/dist/idgenie.umd.min.js"></script>

<!-- Or pin to a specific version -->
<script src="https://cdn.jsdelivr.net/npm/idgenie@1.1.0/dist/idgenie.umd.min.js"></script> or
<script src="https://unpkg.com/idgenie@1.1.0/dist/idgenie.umd.min.js"></script>

<script>
  const id = idgenie.uniqueId({ length: 20, prefix:'manikant' });
  console.log(id);
</script>
```


## Usage After Installation

### Importing

```javascript
// ES Module
import { uniqueId } from "idgenie";

// CommonJS
const { uniqueId } = require("idgenie");
```

### Basic Example

```javascript
// Generate Default unique id

const id = uniqueId();
console.log(id); // Outputs unique id string


// Generate Custom unique id using options parameters --->

const customId = uniqueId({length: 20, prefix:'mani', suffix:'kumar'});
// It will generate unique id of length 20 + prefix + suffix

const customId = uniqueId({mode:'uuid'});
// It will generate unique uuid

const customId = unqiueId({randomLength: true, alphabet:'manikant123', includeDate: true, casing:'upper', secure: true, separator:'#'});
// It will generate random length of custom unique id between 8-36 also it'll take my 'manikant123' alphabet to generate id and include date, separator('#') where need and
// generate id securely using crypto and give Unique id in Uppercase as passed casing 'upper'

console.log(customId); // Outputs custom id string 

// You can use in the same way options as your needs else use without it for just id
```
