README
This is a fork of the Magento Composer Installer repo that provides support for Magento 2 components (modules, themes, language packages, libraries and components).
Usage
In the component's composer.json, specify:
-
type, type of Magento 2 component. -
extra/map, list of files to move and their paths relative to the Magento root directory. -
extra/chmod, list of permissions that should be set for files.Note:
extra/mapis required only if your component needs to be moved to a location other than<Magento root>/vendor. Otherwise, omit this section.extra/chmodis required only if you need to set specific permissions for files.
Supported Components
The following list explains the use of type in composer.json.
Magento Module
"type": "magento2-module"
Installation location: Default vendor directory or as defined in extra/map
Example:
{
"name": "magento/module-core",
"description": "N/A",
"require": {
...
},
"type": "magento2-module",
"extra": {
"map": [
[
"*",
"Magento/Core"
]
]
}
}
Final location is <magento root>/app/code/Magento/Core
Magento Theme
"type": "magento2-theme"
Installation location: app/design
Example:
{
"name": "magento/theme-frontend-luma",
"description": "N/A",
"require": {
...
},
"type": "magento2-theme",
"extra": {
"map": [
[
"*",
"frontend/Magento/luma"
]
]
}
}
Final location is <magento_root>/app/design/frontend/Magento/luma
Magento Language Package
"type": "magento2-language"
Installation location: app/i18n
Example:
{
"name": "magento/language-de_de",
"description": "German (Germany) language",
"require": {
...
},
"type": "magento2-language",
"extra": {
"map": [
[
"*",
"Magento/de_DE"
]
]
}
}
Final location is <magento_root>/app/i18n/Magento/de_DE
Magento Library
"type": "magento2-library"
Support for libraries located in lib/internal instead of in the vendor directory.
Example:
{
"name": "magento/framework",
"description": "N/A",
"require": {
...
},
"type": "magento2-library",
"extra": {
"map": [
[
"*",
"Magento/Framework"
]
]
}
}
Final location is <magento_root>/lib/internal/Magento/Framework
Magento Component
"type": "magento2-component"
Installation location: Magento root directory
Example:
{
"name": "magento/migration-tool",
"description": "N/A",
"require": {
...
},
"type": "magento2-component",
"extra": {
"map": [
[
"*",
"dev/tools/Magento/Tools/Migration"
]
]
}
}
Final location is <magento_root>/dev/tools/Magento/Tools/Migration
Autoload
After handling all Magento components, <magento_root>/app/etc/vendor_path.php specifies the path to your vendor directory.
This information allows the Magento application to utilize the Composer autoloader for any libraries installed in the vendor directory. The path to vendor varies between particular installations and depends on the magento_root setting for the Magento Composer installer. That's why it should be generated for each installation.
You must run composer install to install dependencies for a new application or composer update to update dependencies for an existing application.
Deployment Strategy
The Magneto Composer Installer uses the copy deployment strategy. It copies each file or directory from the vendor directory to its designated location based on the extra/map section in the component's composer.json.
There are other deployment strategies that could be used; however, we don't guarantee that any of them will work.
Usage extra/chmod
The following example shows how you can set specific permissions for files.
Example:
{
"name": "magento/module-sample",
"description": "N/A",
"require": {
...
},
"type": "magento2-module",
"extra": {
"chmod": [
{
"mask": "0755",
"path": "bin/magento"
},
{
"mask": "0644",
"path": "some_dir/file.jpg"
}
]
}
}
mask is a bit mask for chmod command
path is a path to file relative to the Magento root folder
Notes
- The extra->magento-root-dir option is no longer supported. It displays only to preseve backward compatibility.
