> HTTP/HTTPS tunnel proxy for luminati.io using round robin strategy.

## Install

```bash
$ npm install luminati-tunnel --save
```

## Usage

The instance is a function that returns a different proxy tunnel every time you call it, using [round robin](https://en.wikipedia.org/wiki/Round-robin_DNS) algorithm.

```js
const luminatiTunnel = require('luminati-tunnel')

const proxies = [ 'proxy1', 'proxy2', 'proxy3' ]
const tunnel = createTunnel(proxies)
const url = 'http://lumtest.com/echo.json'

;(async () => {
  // => it uses 'proxy1'
  await got(url, {
    agent: tunnel(),
    json: true
  })

  // => it uses 'proxy2'
  await got(url, {
    agent: tunnel(),
    json: true
  })

  // => it uses 'proxy3'
  await got(url, {
    agent: tunnel(),
    json: true
  })

  // => it uses 'proxy1'
  await got(url, {
    agent: tunnel(),
    json: true
  })
})()
```
