In some cases you would really want to add a snippet somewhere inside your code, inside script tags. This is how you do it: Let's say you want the snippet inside a controller. Create a custom module and add a file named google_snippet.routing.yml with this content:
google_snippet.page:
path: '/my-custom-path'
defaults:
_title: 'Here is my snippet'
_controller: '\Drupal\google_snippet\Controller\snippetPage::render'
requirements:
_permission: 'access content'
Also add a file google_snippet.module file to make the controller aware of a template file:
function google_snippet_theme($existing, $type, $theme, $path) {
return [
'google_snippet' => [
'variables' => [
'snippet' => NULL
],
],
];
}
Create a file in src/Controller/ named snippetPage.php.
namespace Drupal\google_snippet\Controller;
use Drupal\Core\Controller\ControllerBase;
class snippetPage extends ControllerBase {
public static function render() {
return [
'#theme' => 'google_snippet',
'#snippet' => '
<script>
INSERT YOUR SNIPPET HERE
</script>
',
];
}
}
Then, inside a templates folder of your module a file named google-snippet.html.twig with the following content:
{{ snippet|raw }}
