> Generate sequential IDs, with optional prefix or suffix.

## Installation

```bash
npm i uniqueid --save-dev
```

## Usage

```js
var uniqueid = require('uniqueid')
var first = uniqueid('prefix')
var second = uniqueid(null, 'suffix')

console.log(first()) //=> "prefix0"
console.log(second()) //=> "0suffix"
console.log(first()) //=> "prefix1"
console.log(second()) //=> "1suffix"
```

* **prefix** Set the prefix for id generation (string, default: `''`)
* **suffix** Set the suffix for id generation (string, default: `''`)
