Stimulus connects to form inputs via targets, or a special dataset. Internally, Stimulus creates a variable that can be used anywhere in the controller. For example, we define in the DOM an alias called name:

<div data-controller="aliasController">
<input type="text" data-aliasController-target="name">
</div>

While in the controller, we define the following:

static targets = [ "name" ]

From here, I can call the target within any function/method in the following way:

this.nameTarget

As you can see, the alias is joined with the target text.

In the application we are developing, we have defined the target with the name myText:

static targets = [ "myText" ]

We update the DOM of the input as follows:

<input type="text" data-transformer-target="myText" 
  placeholder="Enter text">
