Optimize Composer for Drupal projects

, _(*1)

About

This composer-plugin contains a set of improvements that makes running heavy duty composer commands (i.e. composer update or composer require) much faster., _(*2)

Composer 2

Since Composer 2 is quite fast by default, this plugin is not needed, and will be disabled if Composer 2 is detected. If everyone involved in development of a project is using Composer 2, this plugin becomes redundant and can be removed from the list of project dependencies., _(*3)

Installation

composer require zaporylie/composer-drupal-optimizations:^1.1 --dev

No configuration required 🎊, _(*4)

Optimizations

Reduce memory usage and CPU usage by removing legacy symfony tags

Configuration

If no configuration is provided this package will provide sensible defaults based on the drupal/core version constraint in the root composer.json file. Default configuration should cover 99% of the cases. However, in case you want to manually specify the tags that should be filtered out you are welcome to use the extra section:, _(*9)

{
  "extra": {
    "composer-drupal-optimizations": {
      "require": {
        "symfony/symfony": ">3.4"
      }
    }
  }
}

Recommendation note: Use defaults (skip config above) if possible - this package will be maintained throughout the Drupal's lifecycle in order to optimize legacy constraints in parallel with Drupal's requirements., _(*10)

All you have to do is to make sure your drupal core constraint in the root composer.json is set to drupal/core: ^8.5 or above. If you use a Drupal distribution, be sure to explicitly require drupal/core in your own project as well., _(*11)
