Best Practices

1. Twig

• To prevent Drupal from adding extra <div> tags when outputting field values, use the following approach:

content.n_news_image_credit.0['#context'].value instead of simply using: content.n_news_image_credit. unless you have an existing twig template for that field where you add tags and CSS. For example, if you have a file named like so field--node--n_news_image_credit.html.twig.

• When adding links, make sure they are validated for inappropriate characters. For example, one way could be by URL-encoding the url {% set filtered_username_input = node.n_person_social_fb.value.value|url_encode %}
