WebSockets Extension Tests

+ +

As of version 1.7, WebSocket support has been moved out of the core htmx library and into an extension. This server runs a test suite for the htmx WebSocket extension.

+

This extension connects to a WebSocket echo server and can send and receive messages to and from the server.

+ +

Required Attributes

+ + + + + + + + + + + + + +
hx-extMake sure the SSE extension is initialized on every page or page fragment where you use SSE streams.
ws-connectConnects to a WebSocket server. Attribute value must begin with ws:// wss://
ws-sendAdd to a form to submit form data to the websocket server instead of to an HTTP server.
+ +

Example Code

+ +
+<body hx-ext="ws">
+    <div ws-connect="wss://my.websocket.server.com"></div>
+
+	<form ws-send>
+		<input name="WebSocketMessage">
+	<form/>
+</body>

Echo Test

+

Description

+

This test lets you send and receive data to and from the WebSocket server. Every message that you send to the server will be "echoed" +back to you in a separate message

+ +

Example HTML

+ +
+<div hx-ext="ws" ws-connect="ws://localhost/echo">
+
+    <form ws-send>
+        <input type="text" name="message" style="width:500px;" value="This Is The Message" />
+        <input type="submit"/>
+    </form>
+
+    <div id="idMessage"></div>
+</div>

WebSocket Messages

+

Each message just contains a random number generated by the server
