+description: Svelte companion for marko/inertia - configuration defaults and a frontend marker binding for Svelte.
+---
+
+Svelte companion for [`marko/inertia`](/docs/packages/inertia/) and [`marko/vite`](/docs/packages/vite/). It overlays the parent Inertia configuration with Svelte defaults and registers a frontend marker binding so installing multiple Inertia frontend companions fails loudly.
+
+## Installation
+
+```bash
+composer require marko/inertia-svelte
+```
+
+Install the matching frontend dependencies in your app:
+
+```bash
+npm install @inertiajs/svelte svelte @sveltejs/vite-plugin-svelte vite
+```
+
+Refer to the [Inertia.js docs](https://inertiajs.com/) for currently supported versions of each frontend adapter.
+
+## Configuration
+
+This package contributes defaults to the parent `config/inertia.php` namespace:
+
+```php title="packages/inertia-svelte/config/inertia.php"
+return [
+    'assetEntry' => env('INERTIA_SVELTE_CLIENT_ENTRY', 'app/svelte-web/resources/js/app.js'),
+];
+```
+
+| Key | Purpose |
+| --- | --- |
+| `assetEntry` | Vite entry used by browser-rendered Inertia responses. |
+
+## Usage
+
+Render Svelte-backed Inertia pages without passing an asset entry; `marko/inertia` reads it from configuration:
+
+```php
+use Marko\Inertia\Inertia;
+use Marko\Routing\Http\Request;
+use Marko\Routing\Http\Response;
+
+class DashboardController
+{
+    public function __construct(
+        private readonly Inertia $inertia,
+    ) {}
+
+    public function index(Request $request): Response
+    {
+        return $this->inertia->render(
+            request: $request,
+            component: 'Dashboard',
+        );
+    }
+}
+```
+
+Create the client entry at `app/svelte-web/resources/js/app.js`:
+
+```js title="app/svelte-web/resources/js/app.js"
+import { createInertiaApp } from '@inertiajs/svelte';
+import { mount } from 'svelte';
+
+createInertiaApp({
+  resolve: (name) => {
+    const pages = import.meta.glob('./Pages/**/*.svelte', { eager: true });
+    return pages[`./Pages/${name}.svelte`];
+  },
+  setup({ el, App, props }) {
+    mount(App, { target: el, props });
+  },
+});
+```
+
+Create the SSR entry at `app/svelte-web/resources/js/ssr.js`:
+
+```js title="app/svelte-web/resources/js/ssr.js"
+import { createInertiaApp } from '@inertiajs/svelte';
+import createServer from '@inertiajs/svelte/server';
+import { render } from 'svelte/server';
+
+createServer((page) =>
+  createInertiaApp({
+    page,
+    resolve: (name) => {
+      const pages = import.meta.glob('./Pages/**/*.svelte', { eager: true });
+      return pages[`./Pages/${name}.svelte`];
+    },
+    setup({ App, props }) {
+      return render(App, { props });
+    },
+  }),
+);
+```
+
+## API Reference
+
+This package registers `Marko\Inertia\Frontend\InertiaFrontendInterface` to a Svelte marker implementation. Installing more than one Inertia frontend companion produces the same binding conflict protection used by Marko driver siblings.
