js_component

Description

The module provides a streamlined solution for adding simple React or JS based components to the Drupal ecosystem. The module is more developer centric, as it allows developers to define JS components by exposing a plugin or by placing a YAML file within the module or theme directory.

The libraries directive follows the same syntax as what you would expect in a *.libraries.yml. The settings directive allows you to collect information from the site-builder. It follows the same structure as the Drupal form API. Inputted settings are exposed to the JS component using the drupalSettings concept.

Below is an example of what a JS component YAML base definition looks like.

[THEME/MODULE].js_component.yml

component_1:
  label: My React Component
  description: This app will run the world!
  root_id: root
  libraries:
    js:
      /js_component/react-app/build/static/js/main.ca4c6d6d.js: {}
    css:
      theme:
        /js_component/react-app/build/static/css/main.666d445f.css: {}
  settings:
    collect_user_input:
      type: 'select'
      title: 'User Input'
      description: 'Any data you would like to provide to the react application.'
      options:
        option-1: Option 1
        option-2: Option 2
      empty_option: '- Select -'

If you need to encapsulate a component as a twig template file. Which then you can define the following in the JS component definition:

component_2:
  label: Twig Template
  description: The basic twig template example.
  template: js_component/custom/twig-template.html.twig
  libraries:
    css:
      theme:
        /js_component/custom/main.css: {}
  settings:
    header_title:
      type: textfield
      title: Header Title
      description: Input JS component header title.
