### Example front end usage
You can pretty much implement this in your front end however you want, you just need to make a GET request to whatever endpoint the counter container is running at. This is how I use it though...
```html
<html>
<head>
<script>
var counterReq = new XMLHttpRequest();
counterReq.onreadystatechange = function() {
console.log("counterReq ready state is " + this.readyState);
if (this.readyState == 4) {
console.log("counterReq status is " + this.status);
if (this.status == 200) {
document.getElementById("counter").innerHTML = this.responseText + " unique visitors"
} else { // failed to load
console.log("failed to load counter module")
}
}
}
counterReq.open("GET", "https://counter.example.com", true);
counterReq.send();
</script>
</head>
<body>
<div id="counter"></div>
</body>
</html>
```
