WebSockets
WebSockets require upgrading an existing HTTP connection. We’ll see how this is done in the following code example. For more details, see the MDN page Protocol upgrade mechanism.[77]
Many WebSocket libraries exist for various server-side programming languages and frameworks.
Let’s build a web app that uses WebSockets. First, we’ll build it without using htmx. Then, we’ll see how using htmx can simplify the code.

This app demonstrates the following things:
-
It uses Alpine for event handling and storing the message to be sent to the server.
-
It uses the WebSocket JavaScript class.
-
It automatically attempts to reconnect if the WebSocket connection is closed. ...
