Composer Plugins
Example
# Install Symfony Flex (auto-configures recipes)
composer require symfony/flex
# Prestissimo parallel downloads (for Composer 1)
composer global require hirak/prestissimo
# List active plugins
composer plugin list
# Disable a plugin temporarily
composer --no-plugins install Pro Tip
Composer 2 has parallel downloads built-in — no Prestissimo needed for modern projects.
