Dependency Injection

• Replaceable services for dependencies
• Keeps code decoupled
• Services passed to objects by injection when object is created
• Allows replacement of core subsystems with configuration
• Makes it easier to test with mock objects or test multiple subsystem implementations.
• Examples: database connector, configuration manager, translation service
• Services define in modulename.services.yml

Dependency Injection

Drupal 8: A Modern PHP App

By adopting coding standards from the non-Drupal
PHP community, we can integrate and contribute to their work
without having to re-invent everything to fit our Drupalisms.

A Game Plan For Devs

• Start now looking at Drupal 8
• Get familiar with OOP, if you're not
• If you have modules, start porting them
  (realizing you may have redo this later)
• Give feedback on DX to core devs
• Mentor others
