About Composer

Composer is a tool for dependency management in PHP. It allows you todeclare the dependent libraries your project needs and it will install

them in your project for you.

What Composer does…/composer.json

{ "require": { "psr/log": "~1.0", "acme/foo": "*", "monolog/monolog": "dev-master#2eb0c09" }, "require-dev": { "phpunit/phpunit": "~3.7.0" }, "repositories": [ { "type": "vcs", "url": "[email protected]:AcmeCompany/FooLibrary.git" }, ]}

$ composer install

… and howcomposer install

Magento Composer InstallerInstall a module in your project

./composer.json

{ "require": { "foo/bar-module": "*", "magento-hackathon/magento-composer-installer": "*" }, "repositories": [ { "type": "composer", "url": "http://packages.firegento.com" } ], "extra":{ "magento-root-dir": "htdocs/" }}

$ composer install

Magento Composer InstallerFiles mapping

There are several ways how the mapping from files in the package intothe Magento source is accomplished:

1. A mapping in the composer.json2. The MagentoConnect package.xml file3. The modman file (see )github.com/colinmollenhour/modman

Magento Composer InstallerInstall a MagentoConnect module

http://packages.firegento.com/{ "require": { "connect20/locale_mage_community_it_it": "*" }, "repositories": [ { "type": "composer", "url": "http://packages.firegento.com" } ]}

Magento Composer InstallerInstall the Magento-Core and initialize your project

Package magento/core on packages.firegento.com./composer.json

{ "require": { "magento/core": "1.9.0.1" }, "repositories": [ { "type": "composer", "url": "http://packages.firegento.com" } ], "extra":{ "magento-root-dir": "htdocs/" }}

Only 1.9.0.1 avaliable... :(
