This package adds deployer tasks and a command factory for running composer on the command line.
Easiest way is via composer. Just run composer require codenamephp/deployer.composer
in your cli which should install the latest version for you.
Just use the built in tasks in your deployer file or create your own by using the command factory and a command runner or just
extend \de\codenamephp\deployer\composer\task\AbstractComposerTask
