In this short talk, I will discuss the best practices on developing modules for Drupal 8 with an eye on having them compatible with Drupal 9.

For those who don't know yet, Drupal 9 is just around the corner. After a brief discussion of what will change in Drupal when that new version is released, I will show some tools can already perform a health check in your current code.

Finally, we will conclude by discussing the trends in Drupal 8 development that indicate already which type of functions will eventually be deprecated, and how that can be leveraged to minimize future workloads.
