Yii 2 Composer Installer

This is the composer installer for Yii 2 extensions. It implements a new composer package type named yii2-extension, which should be used by all Yii 2 extensions if they are distributed as composer packages.

Usage

To use Yii 2 composer installer, simply set type to be yii2-extension in your composer.json, like the following:

{
	"type": "yii2-extension",
	"require": {
		"yiisoft/yii2": "*"
	},
	...
}

You may specify a bootstrap class in the extra section. The init() method of the class will be executed each time the Yii 2 application is responding to a request. For example,

{
	"type": "yii2-extension",
	...,
	"extra": {
		"bootstrap": "yii\\jui\\Extension"
	}
}

The Installer class also implements a static method setPermission() that can be called after a Yii 2 projected is installed, through the post-create-project-cmd composer script. The method will set specified directories or files to be writable or executable, depending on the corresponding parameters set in the extra section of the composer.json file. For example,

{
	"name": "yiisoft/yii2-app-basic",
	"type": "project",
	...
	"scripts": {
		"post-create-project-cmd": [
			"yii\\composer\\Installer::setPermission"
		]
	},
	"extra": {
		"writable": [
			"runtime",
			"web/assets"
		],
		"executable": [
			"yii"
		]
	}
}
