README

A Symfony bundle for the Twig Components library.

This bundle allows you to create robust, reusable and automatically documented Twig components using the new component tag. Twig components allow you to quickly build and maintain your own UI toolkit, where each button, table or card has to be designed only once and can be used throughout your entire application.

This Twig Components bundle for Symfony makes life a little bit easier by automatically searching your template directories for defined components, every time the Symfony container is compiled.

For more information about Twig Components, see the documentation.

Setup and Usage

You can install this bundle through Composer:

$ composer require redant/twig-components-bundle

When this bundle is enabled in your Symfony bundle configuration, if will search all your template directories for defined components, every time the container is compiled.

This includes:

• The templates/components folder (main application templates)
• Every installed bundle's Resources/views/components folder (if defined)

Global variable

If you don't like the name of the global variable that defines the components, use the twig_components.global_variable parameter to change this:

# app/config/twig.yaml

twig_components:
    global_variable: 'ui'

This will register the button component as ui.button().

Note: If you set the prefix to false, no Twig global will be registered for defined components. You can then only use the render_component function.

Namespaces

If you define your components in subdirectories of the components/ directory, the additional directories will namespace your component.

For example, a component defined in components/ui/button.html.twig will be accessible as component.ui.button({}) or via render_component('ui.button', {}).

Generate documentation

The added bonus to creating component definitions is the automatic creation of documentation. It explains, for instance, what your component can be used for and which parameters it accepts. For example, the Twig Components bundle can automatically generate a table like this for an example button component:

You can generate a static HTML file with documentation using the supplied twig:components:generate-docs command.

Description:
  Generate documentation for Twig components

Usage:
  twig:components:generate-docs [options] <path>

Arguments:
  path                  Output directory

Options:
  --title=TITLE         Title for the generated documentation [default: "Twig components"]
  --generic             Disregard twig_component.global_variable settings and only show render_component() examples```

Pro tip: When you start your component template file with a comment ({# ... #}), its contents will be added at the top of the documentation for the component.
