<h1>ntfy.sh: EventSource Example</h1>
<p>
This is an example showing how to use
<a href="https://ntfy.sh">ntfy.sh</a> with
<a href="https://developer.mozilla.org/en-US/docs/Web/API/EventSource"
>EventSource</a
>.<br />
This example doesn't need a server. You can just save the HTML page and
run it from anywhere.

<button id="publishButton">Send test notification</button>
<p><b>Log:</b></p>
<div id="events"></div>
<script type="text/javascript">

const events = document.getElementById("events");

// Publish button
document.getElementById("publishButton").onclick = () => {
fetch(publishURL, {
method: "POST", // works with PUT as well, though that sends an OPTIONS request too!

});
