By default, Yii2's Advanced template has console, frontend, and backend applications. However, in your specific case, you can rename the existing ones and create your own applications. For example you can add the api application if you develop an API for your site.
Create a new yii2-app-advanced project by using the Composer package manager, as described in the official guide at https://github.com/yiisoft/yii2-app-advanced/blob/master/docs/guide/start-installation.md.
- Copy the
backenddirectory content to a newapidirectory in the root of your application. - Open the
api/config/main.phpfile and change thecontrollerNamespaceoption value:return [ 'id' => 'app-manager', 'basePath' => dirname(__DIR__), 'controllerNamespace' => 'apicontrollers', // .... ] - Open
api/assets/AppAsset.phpandapi/controllers/SiteController.phpand change the namespaces frombackendtoapilike this:namespaces apiassets; namespaces apicontrollers;
- Open the
api/views/layouts/main.phpfile and find the following row:use backendassetsAppAsset;
Change it to this:
use apiassetsAppAsset;
- Open
common/config/bootstrap.phpand add the@apialias for the new application:<?php Yii::setAlias('@common', dirname(__DIR__)); Yii::setAlias('@frontend', dirname(dirname(__DIR__)) . '/frontend'); Yii::setAlias('@backend', dirname(dirname(__DIR__)) . '/backend'); Yii::setAlias('@console', dirname(dirname(__DIR__)) . '/console'); Yii::setAlias('@api', dirname(dirname(__DIR__)) . '/api); - Open the
environmentsdirectory, and in thedevandprodsubdirectories make theapidirectories copies ofbackend. - Open the
environments/index.phpfile and add rows for theapiapplication:return [ 'Development' => [ 'path' => 'dev', 'setWritable' => [ 'backend/runtime', 'backend/web/assets', 'frontend/runtime', 'frontend/web/assets', 'api/runtime', 'api/web/assets', ], 'setExecutable' => [ 'yii', 'tests/codeception/bin/yii', ], 'setCookieValidationKey' => [ 'backend/config/main-local.php', 'frontend/config/main-local.php', 'api/config/main-local.php', ], ], 'Production' => [ 'path' => 'prod', 'setWritable' => [ 'backend/runtime', 'backend/web/assets', 'frontend/runtime', 'frontend/web/assets', 'api/runtime', 'api/web/assets', ], 'setExecutable' => [ 'yii', ], 'setCookieValidationKey' => [ 'backend/config/main-local.php', 'frontend/config/main-local.php', 'api/config/main-local.php', ], ], ];
Now you have the console, frontend, backend, and api applications.
The Advanced application template is a set of applications with custom aliases, such as @frontend, @backend, @common, and @console and corresponding namespaces instead of the simple @app alias for the Basic template.
You can easily add, remove, or rename this applications (with their aliases and namespaces) if needed.
