Experience with building modules for Drupal 8. No laptop is required. This is a presentation, not a live demo.
This might be a nice practical part of the Gabor's State of Drupal 9 session. Let's upgrade a regular Drupal 8 module to make it compatible with Drupal 9. Just to be clear: this is not a live demo, rather a summary of already implemented steps.
The following items will be covered:
- Briefly touch what the deprecation policy in Drupal is
- How to run check for deprecations using Upgrade Status and drupal-check CLI
- What do deprecation messages mean and how to deal with them
- Let's fix them one-by-one!
