Drupal module development

Drupal's contributed module ecosystem covers most common needs, so custom development should be reserved for genuinely unique business logic, integrations with systems that don't have an existing connector, or performance-critical functionality. Reaching for custom code before checking the contrib ecosystem tends to create unnecessary long-term maintenance burden.

Custom code that ignores Drupal coding standards, lacks tests, or bypasses core APIs becomes a maintenance liability. It's harder to upgrade across Drupal versions, harder to hand over to a new support provider, and a common source of security vulnerabilities if it isn't kept current. That's why coding standards and continuous integration testing matter as much for custom modules as for the rest of your site.

Where the functionality is generic rather than client-specific, yes. It's part of how the Drupal ecosystem sustains itself, and teams that contribute tend to write higher-quality custom code as a side effect.

 We maintain a portfolio of open-source modules, listed on our drupal.org profile. Key examples:

• Augmentor: adds AI services to the editing experience, with submodules for OpenAI, NLP Cloud, and Google Cloud Vision.
• Convivial Core, Convivial Content, Convivial Enricher, and Convivial Profiler: the building blocks of Convivial's personalisation. Enricher adds to user profiles from a CRM or other backend source, and Profiler tracks visitor interests in the browser.
• Entity Class Formatter: lets editors apply CSS classes to any content item without custom fields.
• Modifiers/Modifiers Pack: lets editors apply colours, backgrounds, spacing, and animated effects to paragraphs and sections without a developer.
