Demystifying Composer


  • David Hernandez

We've started embracing the world of Composer, the PHP dependency manager. However, it has become one of the biggest pain points reported by Drupal 8 developers. Once using Composer with Drupal, you can no longer simply download zip files to manage your project.

I will go over Composer basics; starting from scratch, and going step-by-step through a full project build. I will also go over why this has been so difficult with Drupal.

This will cover many of the topics and steps in a tutorial I've posted on Github.

Topics this will include:

  • Composer.json and composer.lock files
  • Adding dependencies and development dependencies
  • Adding repositories
  • Managing version numbers
  • Scaffolding and scripts
  • Using the create-project command
  • Patches

This is beginner level information, but one should be familiar with Drupal 8 folder structures and basic command line usage. Familiarity reading JSON files will also help.
