DrupalCamp Ghent 2014 - Developing Drupal 7 with Drupal 8 in mind
- 1. Develop a Drupal 7 project with Drupal 8 in mind Joeri van Dooren
- 2. WHOAMI Who Am I Joeri van Dooren Technical Coach @ SAGA Consulting Group @Ozmodiar https://www.drupal.org/u/ozmodiar
- 4. Context • Long life span • A lot of custom code • A lot of developers • Drupal 8 vs Drupal 7
- 5. Challenges • Migration of custom code to D8 • External libraries • “Big project syndrome”
- 7. Setup The problems… • Unreadable • Unmaintainable • Not testable (enough) • Not upgradable Vanilla Drupal 7 Object Oriented Code
- 8. Setup Vanilla Drupal 7 What have we done? • xautoload module • Drupal 8 class structure Object Oriented Code
- 10. Setup The problems… • Always re-instantiating classes • Not very maintainable • Not the D8 way Vanilla Drupal 7 Object Oriented Code Dependency Injection
- 11. Setup Vanilla Drupal 7 Object Oriented Code Dependency Injection What have we done?
- 12. Code sample: DI
- 13. Setup This is better, but… • Still not very readable • Not flexible enough • More D8 style, but… • D8 has a better solution Vanilla Drupal 7 Object Oriented Code Dependency Injection Container
- 14. Vanilla Drupal 7 Setup Object Oriented Code Dependency Injection Container What have we done? • Custom module • Symfony Container • D8 uses that too! • Copy paste library • xautoload module
- 16. Setup This is way better but… • Bad library maintenance • D8 has a better solution! Vanilla Drupal 7 Object Oriented Code Dependency Injection Container Dependency Manager
- 17. Vanilla Drupal 7 Setup Object Oriented Code Dependency Injection Container Dependency Manager What have we done? • Introduced Composer • Better library management • Libraries not in VCS • Drupal 8 uses that too!
- 18. Composer • Package Manager • Packagist.org or other VCS • composer.json • Vendor folder • Autoloading
- 20. Setup Vanilla Drupal 7 Object Oriented Code Dependency Injection Container Dependency Manager
- 21. Achievements • Easy external libraries • More Drupal 8 compliant • Object Oriented • Module structure • DI with Symfony Container • Less steep learning curve for D8 module dev
- 22. Extra advantages • Readability • Maintainability • Extensibility • Easy debugging • Better testing • We got off the island (in D7!)
- 23. Points of attention • Developers need a new mindset • Work around D7 limitations • Different code reviews
- 24. The next level • Run your own Packagist (or Satis) • Write your own interfaces to improve code reviews • Write modules as libraries with a Drupal module as adapter

Editor's Notes
- #3: - Inactivity…
- #4: 5 business units IT projects -> custom projects in Drupal for tourist organisations Online Communication -> websites in Drupal (and other technologies)
- #5: Big project More than a year ago
- #7: -
- #9: Maintainability: Classname veranderen = overal aanpassen door heel de code
- #11: Maintainability: Classname veranderen = overal aanpassen door heel de code
- #15: - Put very simple: Box full of references to classes that contain business logic, refered to as “services”.
- #24: Todo overwegen nadelen voor voordelen
