I am an junior developer and have been learning how to capture data using HTML GET requests and Java Servlets + JSP pages for display. I found JSON Placeholder to be extremely useful for learning how to capture sets of data. Although now I have to capture continuously updated data over SSE. I am completely new to the idea of SSE and want to learn. In order to learn I would like if there was dummy website that was sending out data that I could subscribe to. The only alternative to this would be to learn how to setup my own but I am not too familiar with PHP, Node.js or ASP. So, are there any resources that already do this or will I have to set up my own?
Here is the code that I have been messing with to display the Events:
<!DOCTYPE html>
<html>
<body>
<h1>Getting server updates</h1>
<div id="result"></div>
<script>
if(typeof(EventSource) !== "undefined") {
var source = new EventSource("This is where I need the placeholder");
source.onmessage = function(event) {
document.getElementById("result").innerHTML += event.data + "<br>";
};
} else {
document.getElementById("result").innerHTML = "Sorry, your browser does not support server-sent events...";
}
</script>
</body>
</html>
