Weird message: listening on http://::1:3000

When running `npm run dev` on a fresh project


```bash
[dev]
listening on http://::1:3000
```

Should be `listening on http://localhost:3000`

I found the bug in `skel/index.js`

```js
app.listen(port, '::1', err => {
	if (err) {
		return console.err(err)
	}
	log(`listening on http://::1:${ port }`)
})
```
