Understanding Drupal: A Complete Guide to Caching Layers

I have been reading The Pragmatic Programmer and just finished the Concurrency chapter.

My projects all use DDEV for local development. Regarding end-to-end testing, as part of my continuous integration process, I also use DDEV! This way, my scripts for running Cypress are the same locally and in my CI.

One of my favorite development tasks is performance engineering. I love taking an application and analyzing it to increase performance. Application performance monitoring (APM) tools like New Relic and Blackfire.io are tools every developer should have in their toolkit.

Drupal has a key-value database table that stores information about the current environment. The values stored are serialized PHP objects or arrays. That makes inspecting them nearly impossible by just querying the database. Luckily, Drush provides a state:get command for retrieving those values.

Drupal's service container for dependency injection allows modules to register services and parameters to the service container or alter and modify the service container.

Last week I wrote about dependency injection anti-patterns in Drupal. These anti-patterns occur when your service's constructor has logic that interacts with the injected dependent services beyond assigning them to properties.

Whenever I have done an audit for a Drupal codebase, one of the first things I manually review and profile is dependency injection anti-patterns in custom code and any contributed modules used. The anti-pattern isn't for accessing services statically through \Drupal: service. These anti-patterns live within the class's __construct method.

Last year at DrupalCon Portland 2022, Dries announced that "Drupal is for ambitious site builders." It refined the "Drupal is for ambitious digital experiences" vision.

My site runs on Drupal 9.5. I started preparing to upgrade to Drupal 10 right after 10.0.0 was released, but then I got hit with CKEditor 4 to CKEditor 5 blockers.
