JSON:API Basic Site Settings

This simple module created to provide key site settings to the frontend via JSON:API. It also has an API hook to add some additional information to data. After enabling module, you can open /jsonapi/site/site URL and read data. You must use key_auth authentication provided by Key Auth module, to prevent unauthorized access.

This module is needed for sites where the frontend is separated from the backend (the so-called decoupled sites), and eliminates the need for the frontend to obtain general data about the site:

• name => system.site.name
• mail => system.site.mail
• slogan => system.site.slogan
• page_front => system.site.page.front
• page_403 => system.site.page.403
• page_404 => system.site.page.404
• default_langcode => system.site.page.default_langcode
• default_theme => system.theme.default
• admin_theme => system.theme.admin
• global_logo => system.theme.global.logo.path
• global_favicon => system.theme.global.favicon.path

Also, you can add any additional information to JSON:API response via alter hook hook_jsonapi_site_data_alter(&$data):

function hook_jsonapi_site_data_alter(&$data) {
  $data['additional'] = t('Some text');
}

In conjunction with JSON:API Extras module you can get a full API info for your backend.
