Philosophy and Purpose

BLT is designed to improve efficiency and collaboration across Drupal projects by providing a common set of tools and standardized structure. It was born out of the need to reduce re-work, project set up time, and developer onboarding time.

Its explicit goals are to:

  • Provide a standard project template for Drupal based projects
  • Provide tools that automate much of the setup and maintenance work for projects
  • Document and enforce Drupal standards and best practices via default configuration, automated testing, and continuous integration

Its scope is discretely defined. It is not intended to provide:

  • Drupal application features (e.g., workflow, media, layout, pre-fabbed content types, etc.)
  • A local hosting environment
  • A replacement for good judgement (as with Drupal, it leaves you the freedom to make mistakes)


  • Git Hooks
    • pre-commit: Checks for Drupal coding standards compliance
    • commit-msg: Check for proper formatting and syntax
  • Testing Framework.
    • Behat: default local.yml configuration, example tests, FeatureContext.php
    • PHPUnit: default tests for ensuring proper functioning of BLT provided components
  • Project tasks
    • Executing tests and validating code
    • Building dependencies
      • Management of Drupal core, contrib, and third party libraries via Composer
      • Building front end assets. E.g, via gulp, npm, bower, etc.
    • (Re)installation of Drupal
    • Configuration import
  • Artifact Generation
    • Building production-only dependencies
    • Sanitation of production code
  • Continuous Integration & Deployment

Support and contribution

BLT is provided as an open source tool in the hope that it will enable developers to easily generate new Drupal projects that conform to Acquia Professional Services' best practices.
