Yii 2 API Project Template

Yii 2 API Project Template is a skeleton Yii 2 application best for developing complex Web applications with multiple tiers.

The template includes three tiers: front end, back end, api, and console, each of which is a separate Yii application.

The template is designed to work in a team development environment. It supports deploying the application in different environments.

INSTALLATION

Install via Composer

If you do not have Composer, you may install it by following the instructions at getcomposer.org.

You can then install this project template using the following command:

composer global require "fxp/composer-asset-plugin:~1.0.0"
composer create-project --prefer-dist --stability=dev wfcreations/yii2-app-api app

Now you should be able to access the application through the following URL, assuming app is the directory directly under the Web root.

http://localhost/app/api/web/
http://localhost/app/backend/web/
http://localhost/app/frontend/web/

CONFIGURATION

Database

Edit the file common/config/db.php with real data, for example:

return [
    'class' => 'yii\db\Connection',
    'dsn' => 'mysql:host=localhost;dbname=yii2app',
    'username' => 'root',
    'password' => '1234',
    'charset' => 'utf8',
];

NOTE: Yii won't create the database for you, this has to be done manually before you can access it.

Enabling JSON Input

To let the API accept input data in JSON format, configure the [[yii\web\Request::$parsers]] property of the request application component to use the [[yii\web\JsonParser]] for JSON input:

'request' => [
    'parsers' => [
        'application/json' => 'yii\web\JsonParser',
    ]
]

Info: The above configuration is optional. Without the above configuration, the API would only recognize application/x-www-form-urlencoded and multipart/form-data input formats.
