Component Installer for Zend Framework 3 and Expressive Applications

Repository abandoned 2019-12-31

This repository has moved to laminas/laminas-component-installer.

This repository contains the Composer plugin class Zend\ComponentInstaller\ComponentInstaller, which provides Composer event hooks for the events:

post-package-install
post-package-uninstall

Via Composer global install

To install the utility for use with all projects you use:

$ composer global require zendframework/zend-component-installer

Per project installation

To install the utility for use with a specific project already managed by composer:

$ composer require zendframework/zend-component-installer

Writing packages that utilize the installer

Packages can opt-in to the workflow from zend-component-installer by defining one or more of the following keys under the extra.zf configuration in their composer.json file:

"extra": {
  "zf": {
    "component": "Component\\Namespace",
    "config-provider": "Classname\\For\\ConfigProvider",
    "module": "Module\\Namespace"
  }
}

A component is for use specifically with zend-mvc + zend-modulemanager; a Module class must be present in the namespace associated with it. The setting indicates a low-level component that should be injected to the top of the modules list of one of:
- config/application.config.php
- config/modules.config.php
- config/development.config.php
A module is for use specifically with zend-mvc + zend-modulemanager; a Module class must be present in the namespace associated with it. The setting indicates a userland or third-party module that should be injected to the bottom of the modules list of one of:
- config/application.config.php
- config/modules.config.php
- config/development.config.php
A config-provider is for use with applications that utilize expressive-config-manager or zend-config-aggregator (which may or may not be Expressive applications). The class listed must be an invokable that returns an array of configuration, and will be injected at the top of:
- config/config.php

Whitelisting packages to install automatically

At the project level, you can mark packages that expose configuration providers and modules that you want to automatically inject via the component-whitelist key:

"extra": {
  "zf": {
    "component-whitelist": [
      "zendframework/zend-expressive",
      "zendframework/zend-expressive-helpers"
    ]
  }
}

This configuration must be made at the root package level (the package consuming configuration providing packages).
