 **Inertia.js server-side integration layer for [Yii2](https://github.com/yii2-framework/yii2)**
 *Server-driven pages, shared props, redirects, and asset version handling without jQuery*

Features
--------

[](#features)

  ![Feature Overview](./docs/svgs/features-mobile.svg)Overview
--------

[](#overview)

`yii2-framework/inertia` is the server-side base package for building modern Inertia-driven pages on top of Yii2. It does not ship a client adapter. Instead, it defines the server contract that future packages such as `yii2-framework/inertia-vue`, `yii2-framework/inertia-react`, and `yii2-framework/inertia-svelte` can reuse.

Installation
------------

[](#installation)

```
composer require yii2-framework/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],
            ]
        );
    }
}
```

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],
        ],
    ],
];
```

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]);
```

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.
