DEPRECATED

Component Installer has been deprecated. Use one of the following projects instead:

Composer Installers Extender
Asset Packagist
Composer Asset Plugin
Laravel Mix (Example: eventum/eventum#801 and eventum/eventum#812)

Example

composer require oomphinc/composer-installers-extender

  "extra": {
    "installer-types": ["component"],
    "installer-paths": {
      "components/{$name}/": ["type:component"]
    }
  }

Component Installer for Composer

Allows installation of Components via Composer.

Install

composer require robloach/component-installer

{
    "require": {
        "robloach/component-installer": "*"
    }
}

Usage

To install a Component with Composer, add the Component to your composer.json require key. The following will install jQuery and normalize.css:

composer require components/jquery
composer require components/normalize.css

{
    "require": {
        "components/jquery": "2.*",
        "components/normalize.css": "3.*",
        "robloach/component-installer": "*"
    }
}

Using the Component

The easiest approach is to use the Component statically. Just reference the Components manually using a script or link tag:

<script src="components/jquery/jquery.js"></script>
<link href="components/normalize/normalize.css" rel="stylesheet">

For complex projects, a RequireJS configuration is available, which allows autoloading scripts only when needed. A require.css file is also compiled, including all Component stylesheets:

<!DOCTYPE html>
<html>
    <head>
        <link href="components/require.css" rel="stylesheet" type="text/css">
        <script src="components/require.js"></script>
    </head>
    <body>
        <h1>jQuery+RequireJS Component Installer Sample Page</h1>
        <script>
          require(['jquery'], function($) {
            $('body').css('background-color', 'green');
          });
        </script>
    </body>
</html>

Configuration

There are a number of ways to alter how Components are installed and used.

Installation Directory

It is possible to switch where Components are installed by changing the component-dir option in your root composer.json's config. The following will install jQuery to public/jquery rather than components/jquery:

{
    "require": {
        "components/jquery": "*"
    },
    "config": {
        "component-dir": "public"
    }
}

Defaults to components.

Base URL

While component-dir depicts where the Components will be installed, component-baseurl tells RequireJS the base path that will use when attempting to load the scripts in the web browser. It is important to make sure the component-baseurl points to the component-dir when loaded externally. See more about baseUrl in the RequireJS documentation.

{
    "require": {
        "components/jquery": "*"
    },
    "config": {
        "component-dir": "public/assets",
        "component-baseurl": "/assets"
    }
}

Defaults to components.

Assetic filters

{
    "require": {
        "components/jquery": "*"
    },
    "config": {
        "component-dir": "public/assets",
        "component-baseurl": "/assets",
        "component-scriptFilters": {
            "\\Assetic\\Filter\\GoogleClosure\\CompilerApiFilter": []
        },
        "component-styleFilters": {
            "\\Assetic\\Filter\\CssImportFilter": []
        }
    }
}

Creating a Component

To set up a Component to be installed with Component Installer, have it require the package robloach/component-installer and set the type to component, but it is not necessary:

{
    "name": "components/bootstrap",
    "type": "component",
    "require": {
        "robloach/component-installer": "*"
    },
    "extra": {
        "component": {
            "scripts": [
                "js/bootstrap.js"
            ],
            "styles": [
                "css/bootstrap.css"
            ],
            "files": [
                "img/*.png",
                "js/bootstrap.min.js",
                "css/bootstrap.min.css"
            ]
        }
    }
}

scripts - List of all the JavaScript files that will be concatenated together and processed when loading the Component.
styles - List of all the CSS files that should be concatenated together into the final require.css file.
files - Any additional file assets that should be copied into the Component directory.

Component Name

Components can provide their own Component name. The following will install jQuery to components/myownjquery rather than components/jquery:

{
    "name": "components/jquery",
    "type": "component",
    "extra": {
        "component": {
            "name": "myownjquery"
        }
    }
}

Defaults to the package name, without the vendor.

RequireJS Configuration

Components can alter how RequireJS registers and interacts with them by changing some of the configuration options:

{
    "name": "components/backbone",
    "type": "component",
    "require": {
        "components/underscore": "*"
    },
    "extra": {
        "component": {
            "shim": {
                "deps": ["underscore", "jquery"],
                "exports": "Backbone"
            },
            "config": {
                "color": "blue"
            }
        }
    },
    "config": {
        "component": {
            "waitSeconds": 5
        }
    }
}

Current available RequireJS options for individual packages include:

shim
config
Anything that's passed through config.component is sent to Require.js

Packages Without Composer Support

Using repositories in composer.json allows use of Component Installer in packages that don't explicitly provide their own composer.json. In the following example, we define use of html5shiv:

{
    "require": {
        "afarkas/html5shiv": "3.6.*"
    },
    "repositories": [
        {
            "type": "package",
            "package": {
                "name": "afarkas/html5shiv",
                "type": "component",
                "version": "3.6.2",
                "dist": {
                    "url": "https://github.com/aFarkas/html5shiv/archive/3.6.2.zip",
                    "type": "zip"
                },
                "source": {
                    "url": "https://github.com/aFarkas/html5shiv.git",
                    "type": "git",
                    "reference": "3.6.2"
                },
                "extra": {
                    "component": {
                        "scripts": [
                            "dist/html5shiv.js"
                        ]
                    }
                },
                "require": {
                    "robloach/component-installer": "*"
                }
            }
        }
    ]
}

Packages Without Component Support In composer.json

Using extra in composer.json allows use of Component Installer in packages that don't explicitly provide support for component, but do ship with their own composer.json. Using extra with packages that ship with Component Installer, will override component's settings for that package.

{
    "require": {
        "datatables/datatables": "~1.10"
    },
    "extra": {
        "component": {
            "datatables/datatables": {
                "scripts": [
                    "media/js/jquery.dataTables.js"
                ],
                "styles": [
                    "media/css/jquery.dataTables.css"
                ],
                "files": [
                    "media/js/jquery.dataTables.min.js",
                    "media/css/jquery.dataTables.min.css",
                    "media/images/*.png"
                ]
            }
        }
    }
}
