Connect a Stimulus Controller to your html

Fire a Stimulus Controller Action on a Click Event

Extract a Value from an Stimulus Target Input

Intro to Stimulus

The first thing you need to do is add the `data-controller` attribute the to html that you want to connect to Stimulus.

We added `data-controller="example"` so Stimulus expects an `example_controller.js` file to exist.

In our ExampleController class, we are going to use the `connect` method to show that we've connected our controller to the dom.

Instructor: [0:00] Here we have an HTML file that has a heading of Hello. To connect this heading to a stimulus controller, we need to add data-controller as an attribute to this element.

[0:20] Our controller is going to be named example. Let's head on over to our example_controller file. The first thing we need to do is import controller from stimulus. We need to export a class that extends controller. The controller class has a connect method that fires anytime a stimulus controller is connected to the DOM.

[1:13] Here, we'll console.log("Hello"). When we go over to our browser and pop open the DevTools, if we reload, we'll see that we got Hello from example_controller.

[1:34] To wrap up, the first thing you need to do to connect stimulus to your HTML is add the data-controller attribute. Next, you need to create a controller with the same name as the value of that attribute.

[1:51] Finally, we added a connect method to fire whenever stimulus connected to our HTML.
