Repository architecture¶

The repository architecture is based on the following set of core principles:

• Project dependencies should never be committed directly to the repository.
• The code that is deployed to production should be fully validated, tested, sanitized, and free of non-production tools.
• Common project tasks should be fully automated and repeatable, independent of the environment.

Consequently, there are some aspects of a project’s architecture and workflow that may be unfamiliar to you:

• Drupal core, contributed (contrib) modules, themes, and third-party libraries are not committed to the repository. Contrib module directories that are ignored with .gitignore are populated during build artifact generation.
• The repository is never pushed directly to the cloud. Instead, changes to the repository on GitHub trigger tests to be run using Continuous integration. Changes that pass testing will cause a build artifact to be created and then deployed to the cloud.
• Common project tasks are executed using a build tool (such as Robo) allowing them to execute exactly the same in all circumstances.
