Composer is a must-have tool for any Drupal developers toolkit. Everyone has heard about it but isn't aware of the migration process to composer based Drupal management. This session will help you understand the importance of composer and walk you the pathway to implement Composer functionality in your Drupal project. Composer is here to stay for long and will make Drupal development easier and fun!
Composer is an open-source one stop shop tool for updating (or reverting) Drupal core, modules, and patches that will also manage all of their dependencies while also help improving your site’s security. This presentation will show you how you can use this powerful tool for your project and what you need to do to use Composer with your current Drupal site.
Composer makes the developer life easier by managing all the external libraries/dependencies for a project. Developer talks to composer for the external libraries he needs; Composer gets these dependencies and organizes them. Using composer in your project alleviates the pain of maintaining and managing the modules and its dependencies. We need to follow certain steps to migrate our existing Drupal project to a composer-based Drupal project.

Start using Composer workflow in your project.
Understand how to migrate your Drupal site structure to a composer-based Drupal template.

I started applying composer functionality in my project by realizing its importance from the Drupal community. During this process, my project had modules/themes installed both from the UI and the Composer. Instead of handling both types, I converted everything into a composer-based module structure. I realized the Importance of having the composer-based Drupal project Structure and migrated my site to the same.
In this presentation I introduce the composer approach and share my experiences during the migration of Drupal project to a Composer-based Drupal Project, specifying it's importance.
