Configuring Composer

After the project template is installed it's a good idea to adjust default composer.json that can be found in the root directory:

{
    "name": "yiisoft/yii2-app-advanced",
    "description": "Yii 2 Advanced Project Template",
    "keywords": ["yii2", "framework", "advanced", "project template"],
    "homepage": "http://www.yiiframework.com/",
    "type": "project",
    "license": "BSD-3-Clause",
    "support": {
        "issues": "https://github.com/yiisoft/yii2/issues?state=open",
        "forum": "http://www.yiiframework.com/forum/",
        "wiki": "http://www.yiiframework.com/wiki/",
        "irc": "irc://irc.freenode.net/yii",
        "source": "https://github.com/yiisoft/yii2"
    },
    "minimum-stability": "dev",
    "require": {
        "php": ">=5.4.0",
        "yiisoft/yii2": "*",
        "yiisoft/yii2-bootstrap": "*",
        "yiisoft/yii2-swiftmailer": "*"
    },
    "require-dev": {
        "yiisoft/yii2-codeception": "*",
        "yiisoft/yii2-debug": "*",
        "yiisoft/yii2-gii": "*",
        "yiisoft/yii2-faker": "*"
    },
    "config": {
        "process-timeout": 1800
    },
    "extra": {
        "asset-installer-paths": {
            "npm-asset-library": "vendor/npm",
            "bower-asset-library": "vendor/bower"
        }
    }
}

First we're updating basic information. Change name, description, keywords, homepage and support to match your project.

Now the interesting part. You can add more packages your application needs to the require section. All these packages are coming from packagist.org so feel free to browse the website for useful code.

After your composer.json is changed you can run composer update --prefer-dist, wait till packages are downloaded and installed and then just use them. Autoloading of classes will be handled automatically.
