Making my modules Drupal 9 ready

At the moment I'm a maintainer or co-maintainer of 22 Drupal projects. Only two of them are Drupal 7 modules, the rest are Drupal 8 modules. My plan for those 20 modules is to make them Drupal 9 ready by June 3, 2020, which is the date when Drupal 9 should be released.

I don't want to just make them Drupal 9 ready, I also want to add as many tests as I could. At the time I wrote most of my modules I didn't know much about writing PHPUnit tests. Now, when I'm more comfortable writing tests I want to add tests when that makes sense. Adding tests will ensure the stability of my modules in the future, and will also make adding new features much easier.

I started this journey several weeks ago, so some of my modules are already Drupal 9 ready. I'm adding a notice to let users know that the module is Drupal 9 ready.

In this blog post, I will keep track of my progress. Here's the list of my modules which are compatible with Drupal 9:

• Hierarchical Taxonomy Menu
• Projects Stats
• SVG Formatter
• Cyrillic to Latin
• Config Delete
• Twig Render This
• Commerce Quick Edit
• Facets Block
• CKEditor Format Buttons
• Commerce Price Updater
• Modal Widget
• Commerce Shopping Hours
• Simple Facebook Pixel
• Facets Block
• Commerce Variation Add to Cart
• Behance Block
• My Notes
• Remote Config Sync

You can also make your site Drupal 9 ready.
