Conditional fields in Paragraphs using the Javascript States API for Drupal 8

While creating content, there are pieces of information that are only relevant when other fields have a certain value. For example, if we want to allow the user to upload either an image or a video, but not both, you can have another field for the user to select which type of media they want to upload. In these scenarios, the Javascript States API for Drupal 8 can be used to conditionally hide and show the input elements for image and video conditionally.

Disposable Drupal installations with drush

Sometimes we need a Drupal installation for a quick test of a module, theme, or feature that we are working on. You can have a LAMP stack installed locally or, as we do at Agaric, use virtual machines. In both cases, it can take a considerable amount of time to make the required configuration to install Drupal. It is possible to avoid all that by leveraging Drupal’s support for SQLite and using PHP’s built in web server. Let me show you how to easily create a disposable installation with a few drush commands.

Altering views' results

Let's see how to do it using the hooks provided by the module.
