What are Anonymous Template Component Prefixes in Sylius?

Before diving into anonymous template components, let's start with the basics. A template component, also known as a Twig Component, allows you to bind an object to a template. This makes it easier to render and reuse UI elements, such as modals or category sidebars, across multiple areas of your application.

In contrast to traditional Twig Components, which require both a class and a template, anonymous template components are self-contained templates that define the component directly within the template itself.

Consider a file named templates/components/Button/Primary.html.twig with the following content:

<button {{ attributes.defaults({class: 'primary'}) }}>
    {% block content %}{% endblock %}
</button>

The file's location and directory structure allow us to reference this component as Button:Primary. To include this component in a template, you can use the following syntax:

<div>
   <twig:Button:Primary>I am a button!</twig:Button:Primary>
</div>

In the context of anonymous template components, the component name is tightly coupled with the directory structure. However, Sylius provides a flexible solution to this constraint. With Sylius, you can:

• define custom prefixes for your components
• specify a custom directory structure where these components are stored

This feature allows for greater control and organization of your components, making it easier to manage and maintain your template components.

To take advantage of Sylius's anonymous template component feature, you need to define a prefix and its corresponding directory structure in your configuration. For example, you can add the following configuration:

sylius_ui:
    twig_ux:
        anonymous_component_template_prefixes:
            my_shop: 'shop/shared/my_components'

This configuration tells Sylius to look for templates with the my_shop prefix in the shop/shared/my_components directory.

Once you've defined the prefix and directory structure, you can create a template in the specified directory. For instance, you can create a my_button.html.twig template in the shop/shared/my_components directory.

To use this template in your Twig template, reference it using the component file name and the defined prefix:

{{ component('my_shop:my_button') }}

By using anonymous component prefixes, you can keep your templates organized and structured in a way that makes sense for your Sylius application, making it easier to maintain and manage your codebase.
