# uid2
[](http://badge.fury.io/js/uid2)
Generate unique ids. Pass in a `length` and it returns a `string`.
## Installation
npm install uid2
## Examples
Without a callback it is synchronous:
```js
uid(10)
// => "hbswt489ts"
```
With a callback it is asynchronous:
```js
uid(10, function (err, id) {
if (err) throw err;
// id => "hbswt489ts"
});
```
