It does not ship a client adapter. Instead, it defines the server contract that future packages such as `yii2-extensions/inertia-vue`, `yii2-extensions/inertia-react`, and `yii2-extensions/inertia-svelte` can reuse. Installation ------------ [](#installation) ``` composer require yii2-extensions/inertia:^0.1 ``` Register the bootstrap class in your application configuration: ``` return [ 'bootstrap' => [\yii\inertia\Bootstrap::class], ]; ``` Quick start ----------- [](#quick-start) Render a page directly from a controller action: ``` use yii\inertia\Inertia; use yii\web\Controller; use yii\web\Response; final class SiteController extends Controller { public function actionIndex(): Response { return Inertia::render( 'Dashboard', ['stats' => ['visits' => 42]], ); } } ``` Or extend the convenience controller: ``` use yii\inertia\web\Controller; use yii\web\Response; final class SiteController extends Controller { public function actionIndex(): Response { return $this->inertia( 'Dashboard', [ 'stats' => ['visits' => 42], ] ); } } ``` Or inject the renderer contract. `Bootstrap` binds `ResponseRendererInterface` to `InertiaRenderer` in the DI container, so the action stays decoupled from the Inertia implementation and overlays (Inertia, JSON, API) can swap the renderer without rewriting controller code: ``` use yii\inertia\web\ResponseRendererInterface; use yii\web\{Controller, Response}; final class SiteController extends Controller { public function __construct( $id, $module, private readonly ResponseRendererInterface $renderer, $config = [], ) { parent::__construct($id, $module, $config); } public function actionIndex(): Response|string { return $this->renderer->render('Dashboard', ['stats' => ['visits' => 42]]); } } ``` Configuration example --------------------- [](#configuration-example) ``` use yii\inertia\Manager; return [ 'bootstrap' => [\yii\inertia\Bootstrap::class], 'components' => [ 'inertia' => [ 'class' => Manager::class, 'id' => 'app', 'rootView' => '@app/views/layouts/inertia.php', 'version' => static function (): string { $path = dirname(__DIR__) . '/public/build/manifest.json'; return is_file($path) ? (string) filemtime($path) : ''; }, 'shared' => ['app.name' => static fn(): string => Yii::$app->name], ], ], ]; ``` Dev server support (Vite) ------------------------- [](#dev-server-support-vite) The bundled `\yii\inertia\Vite` helper component renders asset tags for both development and production. When `devMode`is `true`, it emits `@vite/client` plus each configured entrypoint from `devServerUrl`, enabling Vite's HMR WebSocket end-to-end. When `devMode` is `false`, it reads the manifest at `manifestPath` and renders hashed asset tags for production. Typical development flow: run `npm run dev` to start the Vite dev server and launch Yii2 with a dev environment flag (for example, `YII_ENV=dev ./yii serve`). `YII_ENV` does not toggle `Vite::$devMode` on its own; your application configuration must wire the two together, for example: ``` 'components' => [ 'inertiaVite' => [ 'class' => \yii\inertia\Vite::class, 'devMode' => YII_ENV === 'dev', // ... ], ], ``` For framework-specific setup, see: - [`yii2-extensions/inertia-react`](https://github.com/yii2-extensions/inertia-react) โ€” React Refresh preamble auto-injection. - [`yii2-extensions/inertia-vue`](https://github.com/yii2-extensions/inertia-vue) โ€” Vue HMR (no extra preamble). Prop types (v3) --------------- [](#prop-types-v3) The package supports the Inertia v3 prop types for fine-grained control over when and how props are resolved: ``` use yii\inertia\Inertia; return Inertia::render( 'Dashboard', [ 'stats' => $stats, // regular prop 'users' => Inertia::defer(fn () => User::find()->all()), // loaded after render 'activity' => Inertia::optional(fn () => $user->getActivity()), // only on partial reload 'auth' => Inertia::always(fn () => ['user' => $identity]), // always included 'items' => Inertia::merge($paginated)->append('data', 'id'), // merge instead of replace 'countries' => Inertia::once(fn () => Country::find()->all()), // resolved once, cached ], ); ``` See the [Usage Examples](docs/examples.md) for detailed documentation on each prop type. Validation and flash messages ----------------------------- [](#validation-and-flash-messages) This package maps the session flash key `errors` to `props.errors` and exposes all remaining flashes at the top-level `flash` page key. A typical validation redirect looks like this: ``` if (!$model->validate()) { Yii::$app->session->setFlash('errors', $model->getErrors()); return $this->redirect(['create']); } Yii::$app->session->setFlash('success', 'Record created.'); return $this->redirect(['view', 'id' => $model->id]); ``` CSRF protection --------------- [](#csrf-protection) Drop in `yii\inertia\web\Request` to enable Inertia's automatic cookie-to-header CSRF flow: ``` 'request' => [ 'class' => \yii\inertia\web\Request::class, 'cookieValidationKey' => 'your-secret-key', ], ``` Inertia's HTTP client reads the `XSRF-TOKEN` cookie and sends it as `X-XSRF-TOKEN` automatically no client-side configuration required. See the [Configuration Reference](docs/configuration.md) for details. Package boundaries ------------------ [](#package-boundaries) This repository intentionally does not include Vue, React, or Svelte bootstrapping. Those concerns belong in separate client adapter packages built on top of the server contract defined here.
