Serverless Access Counter
In the good old days, we had our Homepage with access counters. Now it's back with new technology.
Note: Access counter in the 21st century is JSON object, not a concatinated image file.
How to Deploy
This counter uses Serverless Framework. It supports AWS only now.
using serverless framework (for user)
$ npm install -g serverless
$ serverless install -u https://github.com/takahashim/sls-access-coutner
$ cd sls-access-coutner
$ serverless deploy
using git (for developer)
$ git clone https://github.com/takahashim/sls-access-coutner.git
$ cd sls-access-counter
$ npm install
$ npm run deploy
How to Use
When you access API Gateway's URL, you can get current count like below:
{"count": 42}
You can embed the number in your homepage. Sample HTML is below:
<html>
<head>
<title>counter sample</title>
</head>
<body>
<h1>counter sample</h1>
<p>counter: <span id="sls-counter"></span></p>
</body>
<script>
var counter_url = "https://your-api-gateway-url";
var request = new XMLHttpRequest();
request.open('GET', counter_url, true);
request.onload = function() {
if (request.status >= 200 && request.status < 400) {
var data = JSON.parse(request.responseText);
document.getElementById('sls-counter').innerHTML = data.count;
}
};
request.send();
</script>
</html>
