Rodrigo Pombo: [0:00] To make a piece of HTML interactive, you need to create a controller class and link an element to the controller with the data-controller attribute. You can use the data-action attribute, for example, to handle click events. Specifying the name of the controller and the method, Stimulus will call the method on every click.
[0:20] To add a state, you can add a property to the controller to display it. First, you need a reference to a DOM element. Stimulus calls those references targets. After you define the target, you can access the DOM element as a controller property. Now every time the state changes, Stimulus re-renders the component.
[0:45] To have two of these buttons, you can duplicate the HTML and reuse the controller. If you add an attribute and apply it as a value in the controller, you can access it as a controller property similar to targets.
