> A simple redis primitives to incr() and top() user agents.
## Install
```sh
npm install @microlink/ua
```
## Usage
First, initialize the library passing a Redis instance:
```js
const Redis = require('ioredis')
const redis = new Redis()
const ua = require('@microlink/ua')(redis)
```
After that, the library offers the following methods:
- **incr(userAgent)** — e.g. `ua.incr(req.headers['user-agent'])`
Increment the counter associated with an user agent.
- **top(n, { withScore })** — e.g. `ua.top(100)`
Returns an array of the N ranked from from top.
- **flush** — e.g. `ua.delete()`
Delete elements.
