Render uses a LiveView template to render a view for the state in the socket Mount initialize the state of the LiveView process by assigning values to the socket Stepping back, you gotta admit that’s a lot of functionality for such a minimal amount of code: Now if you head over to you should have a fully-functioning light controller. Def handle_event ( "down", _, socket ) do socket = update ( socket, :brightness, & max ( &1 - 10, 0 )) end ![]()
