Magento Composer Installer

The purpose of this project is to enable composer to install Magento modules, and automatically integrate them into a Magento installation and add Composer's vendor autoloader ability to Magento's so that Composer-compatible 3rd party tools can be used.

If you want to install the Magento Core, you should try AydinHassan/magento-core-composer-installer as an additional plugin.

We strongly recommend you to also read the general composer documentation at

Magento 2

Congratulation to be working with Magento 2. Don't try to use it together with this project. Your princess is in another Castle

Project Details

This project only covers the custom installer for composer. If you have problems with outdated versions, need to install magento connect modules or similar, you need to look for which you probably should add as composer repository (globally)

composer config -g repositories.firegento composer

supported PHP Versions

We don't officially support PHP versions which are End of Life means which they don't get security patches anymore. Even if the install requirement still allows them.
This will change, as soon as someone is willing to pay for supporting them.

support contacts

If you have problems please have patience, as normal support is done during free time.

Known issues

need to redeploy packages

earlier we suggested the use of the command integrator package, that is not needed anymore. composer.phar run-script post-install-cmd -vvv -- --redeploy
This does remove all deployed files and redeploys every module

using non default autoloading

we handle this topic in our FAQ.

Timeouts and slow downloading.

Mostly caused by outages of Github, Repositories or the Internet. This is a common problem with having all packages remote.

For all of this issues you can make use of the commercial Toran Proxy. It also allows hosting of private packages and speeds up the whole downloading process.

Another alternative is to look into Satis, bare git mirrors and repository aliasing.

Another way to speedup downloads over ssh (also interesting for satis users) is to improve your ssh configs. At least for newer versions of openSSH you can add the following to your .ssh/config to reuse previous connections.

Host * 
    ControlPath ~/.ssh/controlmasters/%r@%h:%p
    ControlMaster auto
    ControlPersist 10m

also you need to create the controlmasters directory:

mkdir ~/.ssh/controlmasters
chmod go-xr ~/.ssh/controlmasters

further information can be found on wikibooks


Update the Installer

as this is a composer plugin, you should only use these two commands to update the installer

composer require --no-update  magento-hackathon/magento-composer-installer="3.2.*"
composer update --no-plugins --no-scripts magento-hackathon/magento-composer-installer

the second command needs maybe a --with-dependencies
Depending on your workflow with composer, you may want to use more explicit versions

Install a module in your project

make sure to use the public Magento module repository as composer repository:

composer config -g repositories.firegento composer

configure your magento root dir, the directory where your magento resides:
composer config extra.magento-root-dir "htdocs/"

an example how your project composer.json could look like:

    "repositories": [
            "type": "composer",
            "url": ""
        "magento-root-dir": "htdocs/"

Auto add files to .gitignore

If you want to have the deployed files automatically added to your .gitignore file, then you can just set the auto-append-gitignore key to true:

        "magento-root-dir": "htdocs/",
        "auto-append-gitignore": true

The .gitignore file will be loaded from the current directory, and if it does not exist, it will be created. Every set of module files, will have a comment above them describing the module name for clarity.

Multiple deploys will not add additional lines to your .gitignore, they will only ever be added once.

Adding Composer's autoloader to Magento

Documentation available here.

Overwriting a production setting (DevMode)

        "magento-deploystrategy": "copy",
        "magento-deploystrategy-dev": "symlink"

Example in devmode doc.

Include your project in deployment

When the magento-composer-installer is run, it only looks for magento-modules among your project's dependencies. Thus, if your project is a magento-module and you want to test it, you will need a second composer.json for deployment, where your project is configured as a required package.

If you wish to deploy your project's files (a.k.a. root package), too, you need to setup your composer.json as follows:

    "type": "magento-module",
    "extra": {
        "magento-root-dir": "htdocs/",
        "include-root-package": true


First clone the magento-composer-installer, then install the dev-stuff (installed by default):

./bin/composer.phar install

then run vendor/bin/phpunit in project-root directory.

Note: Windows users please run phpunit with Administrator permissions.
