 Actions are where business logic is stored. The place where you write the functions in Python instead of JavaScript. They are the ones that will be executed when the page is loaded, when a button is clicked, when a form is submitted, etc. The can be launched by the backend or by the frontend. For example, when a button is clicked, the frontend sends a request to the backend to execute an action. But the backend can send a request to the frontend at any time, for example when a new commentary is added to an article then all clients will receive the new commentary. In other words, the actions can be executed by the backend or by the frontend.  The more common actions will be render HTML and send it to the client, but you can do anything you want. They are the heart of Django LiveView.

 It may be the case that the connection is lost, when user has lost the internet connection or the server has been restarted, and it's a problem because Django LiveView depends on a constant connection. In these cases, the client automatically will try to reconnect to the server. But while this happens, the user will have to be informed and any type of interaction blocked. If you do not block user interactions, actions will accumulate in the browser until communication is reestablished. Where they will all be sent at once. If, for example, the user impatiently presses the next page button 10 times, the user will skip 10 pages. It is a problem for him and for the server that will process many instructions at once.
