 HTML over ther Wire, or HTML over the WebSockets, is a strategy for creating real-time SPAs by creating a WebSockets connection between a client and a server. It allows JavaScript to request actions, its only responsibility is to handle events, and the backend handles the business logic as well as rendering HTML. This means you can create pages without reloading the page, without AJAX, APIs or requests. One technology provides a secure, stable and low-delay connection for real-time web applications.

 1. A WebSockets connection, a channel, is established between the client and the server.
 2. JavaScript sends a text, not a request, via WebSockets to the Server (in our case Django).
