Stimulus Twig Helpers

stimulus_controller

This function attaches a Stimulus controller to an HTML element and allows passing values (via data-attributes) that can be accessed within the controller.

These values are useful for providing dynamic data or configuration to your controller’s logic.

<div {{ stimulus_controller('userProfile', {userId: 42, theme: 'dark'}) }}>
    Welcome to your profile!
</div>

{# would render as #}

<div data-controller="userProfile" data-user-profile-user-id-value="42"
     data-user-profile-theme-value="dark">
    Welcome to your profile!
</div>

stimulus_target

This function defines one or more targets within a Stimulus controller. These targets allow you to interact with specific DOM elements directly from your controller’s logic.

<div {{ stimulus_controller('userProfile') }}>
    <span {{ stimulus_target('userProfile', 'name') }}>John Doe</span>
    <span {{ stimulus_target('userProfile', 'avatar') }}>
        <img src="avatar.jpg" alt="John's Avatar">
    </span>
</div>

{# would render as #}

<div data-controller="userProfile">
    <span data-user-profile-target="name">John Doe</span>
    <span data-user-profile-target="avatar">
        <img src="avatar.jpg" alt="John's Avatar">
    </span>
</div>

stimulus_action

This function attaches an event listener to an HTML element, defining actions that trigger specific methods in the controller.

This simplifies event handling by mapping DOM events (like click, input, etc.) directly to controller methods, improving the clarity and maintainability of your code.

<button {{ stimulus_action('userProfile', 'save', 'click') }}>
    Save Profile
</button>

{# would render as #}

<button data-action="click->userProfile#save">
    Save Profile
</button>
