Drupal

This blogposts gives you a summary on how to upgrade to drupal 9 and fix all composer issues.

Drupal 8 is becoming more and more API-first based. This means a lot of imports and exports of data will be done. A thing you might face here, is that the updating of entity reference fields is a bit tricky. Here I'll show you how it is done.

Paragraphs give great power to drupal 8. This code will show you how you can add them programmatically, for example when importing stuff.

When creating custom blocks, sometimes you need to make sure the block is never cached f.e. when including dynamic links. 

These snippets show you how to add hooks in order to generate twig files like mymodule/templates/my-entity--full.html.twig

In the following examples, I loop over a tag field and set a link with classes 

A common task in custom coding is checking whether a field had a value. This snippet helps you with that.

Bundle classes have arrived! In my opinion a major change to drupal and the way we will do theming. Introduced in branch 9.3.x.
