Composer Installers Extender

The composer-installers-extender is a plugin for Composer that allows any package to be installed to a directory other than the default vendor directory within a project on a package-by-package basis. This plugin extends the composer/installers plugin to allow any arbitrary package type to be handled by their custom installer.

The composer/installers plugin has a finite set of supported package types and we recognize the need for any arbitrary package type to be installed to a specific directory other than vendor. This plugin allows additional package types to be handled by the composer/installers plugin, benefiting from their explicit install path mapping and token replacement of package properties.

How to Install

Add oomphinc/composer-installers-extender as a dependency of your project:

$ composer require oomphinc/composer-installers-extender

This plugin requires at least PHP 7.1. If you're using a lower version of PHP use the latest stable 1.x release:

$ composer require oomphinc/composer-installers-extender:^1.1

How to Use

The composer/installers plugin is a dependency of this plugin and will be automatically required as well if not already required.

To support additional package types, add an array of these types in the extra property in your composer.json:

with composer/installers < v1.0.13:

{
    "extra": {
        "installer-types": ["library"]
    }
}

with composer/installers >= v1.0.13:

{
    "extra": {
        "installer-types": ["drupal-library"]
    }
}

Then refer to that type when adding to installer-paths:

with composer/installers < v1.0.13:

{
    "extra": {
        "installer-types": ["library"],
        "installer-paths": {
            "special/package/": ["my/package"],
            "path/to/libraries/{$name}/": ["type:library"]
        }
    }
}

with composer/installers >= v1.0.13:

{
    "extra": {
        "installer-types": ["drupal-library"],
        "installer-paths": {
            "special/package/": ["my/package"],
            "path/to/libraries/{$name}/": ["type:drupal-library"]
        }
    }
}

By default, packages that do not specify a type will be considered the type library. Adding support for this type allows any of these packages to be placed in a different install path.

If a type has been added to installer-types, the plugin will attempt to find an explicit installer path in the mapping. If there is no match either by name or by type, the default installer path for all packages will be used instead.

Please see the README for composer/installers to see the supported syntax for package and type matching as well as the supported replacement tokens in the path (e.g. {$name}).
