Server-side rendering pre-renders your JavaScript pages on the server, allowing your visitors to receive fully rendered HTML when they visit your application. Since fully rendered HTML is served by your application, it’s also easier for search engines to index your site. Server-side rendering uses Node.js to render your pages in a background process; therefore, Node must be available on your server for server-side rendering to function properly.

Laravel Starter Kits

If you are using Laravel Starter Kits, Inertia SSR is supported through a build command: 
npm run build:ssr

​
Vite Plugin Setup

The recommended way to configure SSR is with the @inertiajs/vite plugin. This approach handles SSR configuration automatically, including development mode SSR without a separate Node.js server.
1

Install the Vite plugin

npm install @inertiajs/vite
2

Configure Vite

Add the Inertia plugin to your vite.config.js file. The plugin will automatically detect your SSR entry point.
vite.config.js
import inertia from '@inertiajs/vite'
import laravel from 'laravel-vite-plugin'
import { defineConfig } from 'vite'

export default defineConfig({
    plugins: [
        laravel({
            input: ['resources/css/app.css', 'resources/js/app.js'],
            refresh: true,
        }),
        inertia(),
    ],
})
You may also configure SSR options explicitly.
vite.config.js
inertia({
    ssr: {
        entry: 'resources/js/ssr.js',
        port: 13714,
        cluster: true,
    },
})
You may pass false to opt out of the plugin’s automatic SSR handling, for example if you prefer to configure SSR manually but still want to use the other features of the Vite plugin.
vite.config.js
inertia({
    ssr: false,
})
3

Update your build script

Update the build script in your package.json to build both bundles.
package.json
"scripts": {
    "dev": "vite",
   "build": "vite build"
   "build": "vite build && vite build --ssr"
},

​
Development Mode

The Vite plugin handles SSR automatically during development. There is no need to build your SSR bundle or start a separate Node.js server. Simply run your Vite dev server as usual: 
npm run dev
The Vite plugin exposes a server endpoint that Laravel uses for rendering, complete with HMR support.
The vite build --ssr and php artisan inertia:start-ssr commands are for production only. You should not run them during development.

​
Production

For production, build both bundles and start the SSR server. 
npm run build
php artisan inertia:start-ssr

​
Custom SSR Entry Point

The Vite plugin reuses your app.js entry point for both browser and SSR rendering by default, so no separate file is needed. The plugin detects the data-server-rendered attribute to decide whether to hydrate or mount, and the setup and resolve callbacks are optional. If you need custom SSR logic (such as Vue plugins that should only run on the server), you may create a separate resources/js/ssr.js file. 
import { createInertiaApp } from '@inertiajs/vue3'
import createServer from '@inertiajs/vue3/server'
import { createSSRApp, h } from 'vue'
import { renderToString } from 'vue/server-renderer'

createServer(page =>
    createInertiaApp({
        page,
        render: renderToString,
        resolve: name => {
            const pages = import.meta.glob('./Pages/**/*.vue')
            return pages[`./Pages/${name}.vue`]()
        },
        setup({ App, props, plugin }) {
            return createSSRApp({
                render: () => h(App, props),
            }).use(plugin)
        },
    }),
)
Be sure to add anything that’s missing from your app.js file that makes sense to run in SSR mode, such as plugins or custom mixins.

​
Manual Setup

If you prefer not to use the Vite plugin, you may configure SSR manually.
1

Create an SSR entry point

Create an SSR entry point file within your Laravel project.
touch resources/js/ssr.js
This file will look similar to your app entry point, but it runs in Node.js instead of the browser. Here’s a complete example.
import { createInertiaApp } from '@inertiajs/vue3'
import createServer from '@inertiajs/vue3/server'
import { renderToString } from 'vue/server-renderer'
import { createSSRApp, h } from 'vue'

createServer(page =>
    createInertiaApp({
        page,
        render: renderToString,
        resolve: name => {
            const pages = import.meta.glob('./Pages/**/*.vue')
            return pages[`./Pages/${name}.vue`]()
        },
        setup({ App, props, plugin }) {
            return createSSRApp({
                render: () => h(App, props),
            }).use(plugin)
        },
    }),
)
2

Configure Vite

Add the ssr property to the Laravel Vite plugin configuration.
export default defineConfig({
    plugins: [
        laravel({
            input: ['resources/js/app.js'],
            ssr: 'resources/js/ssr.js', 
            refresh: true,
        }),
        // ...
    ],
})
3

Update your build script

Update the build script in your package.json to build both bundles.
package.json
"scripts": {
    "dev": "vite",
   "build": "vite build"
   "build": "vite build && vite build --ssr"
},

​
Clustering

By default, the SSR server runs on a single thread. You may enable clustering to start multiple Node servers on the same port, with requests handled by each thread in a round-robin fashion.
vite.config.js
inertia({
    ssr: {
        cluster: true,
    },
})
When using a custom SSR entry point or manual setup, you may pass the cluster option to createServer instead. 
createServer(page =>
    createInertiaApp({
        // ...
    }),
    { cluster: true },
)

​
Running the SSR Server

The SSR server is only required in production. During development, the Vite plugin handles SSR automatically.
Once you have built both your client-side and server-side bundles, you may start the SSR server using the following Artisan command. 
php artisan inertia:start-ssr
You may use the --runtime option to specify which runtime you want to use. This allows you to switch from the default Node.js runtime to Bun. 
php artisan inertia:start-ssr --runtime=bun
With the server running, you should be able to access your app within the browser with server-side rendering enabled. In fact, you should be able to disable JavaScript entirely and still navigate around your application.

​
Client-Side Hydration

import { createApp, h } from 'vue'
import { createSSRApp, h } from 'vue'
import { createInertiaApp } from '@inertiajs/vue3'

createInertiaApp({
    resolve: name => {
        const pages = import.meta.glob('./Pages/**/*.vue')
        return pages[`./Pages/${name}.vue`]()
    },
    setup({ el, App, props, plugin }) {
    createApp({ render: () => h(App, props) }) 
    createSSRApp({ render: () => h(App, props) }) 
        .use(plugin)
        .mount(el)
    },
})

​
Error Handling

When SSR rendering fails, Inertia gracefully falls back to client-side rendering. The Vite plugin logs detailed error information to the console, including the component name, request URL, source location, and a tailored hint to help you resolve the issue. Common SSR errors are automatically classified. Browser API errors (such as referencing window or document in server-rendered code) include guidance on moving the code to a lifecycle hook. Component resolution errors suggest checking file paths and casing. Inertia also dispatches an SsrRenderFailed event on the server. You may listen for this event to log failures or send them to an error tracking service. 
use Illuminate\Support\Facades\Log;
use Inertia\Ssr\SsrRenderFailed;

Event::listen(SsrRenderFailed::class, function (SsrRenderFailed $event) {
    Log::warning('SSR failed', $event->toArray());
});

​
Throwing on Error

For CI or E2E testing, you may prefer SSR failures to throw an exception instead of falling back silently. Set the throw_on_error option in your config/inertia.php file. 
'ssr' => [
    'throw_on_error' => (bool) env('INERTIA_SSR_THROW_ON_ERROR', false),
],
You may set the environment variable in your phpunit.xml to catch SSR errors during testing. 
<env name="INERTIA_SSR_THROW_ON_ERROR" value="true"/>

​
Disabling SSR

Sometimes you may wish to disable server-side rendering for certain pages or routes in your application.

​
Per-Route via Middleware

You may use the $withoutSsr property on your Inertia middleware to disable SSR for specific route patterns. 
use Inertia\Middleware;

class HandleInertiaRequests extends Middleware
{
    /**
     * Defines the routes that should not use SSR.
     *
     * @var array<int, string>
     */
    protected $withoutSsr = [
        'admin/*',
        'dashboard',
    ];
}

​
Via Facade

You may also disable SSR for specific routes using the Inertia::withoutSsr() method, typically called from a service provider. 
use Inertia\Inertia;

Inertia::withoutSsr(['admin/*', 'dashboard']);

​
Per-Request

You may disable SSR for the current request by setting the inertia.ssr.enabled configuration value to false. 
if (request()->is('admin/*')) {
    config(['inertia.ssr.enabled' => false]);
}

​
Deployment

When deploying your SSR enabled app to production, you’ll need to build both the client-side (app.js) and server-side bundles (ssr.js), and then run the SSR server as a background process, typically using a process monitoring tool such as Supervisor. 
php artisan inertia:start-ssr
To stop the SSR server, for instance when you deploy a new version of your website, you may utilize the inertia:stop-ssr Artisan command. Your process monitor (such as Supervisor) should be responsible for automatically restarting the SSR server after it has stopped. 
php artisan inertia:stop-ssr
You may use the inertia:check-ssr Artisan command to verify that the SSR server is running. This can be helpful after deployment and works well as a Docker health check to ensure the server is responding as expected. 
php artisan inertia:check-ssr
By default, a check is performed to ensure the server-side bundle exists before dispatching a request to the SSR server. In some cases, such as when your app runs on multiple servers or is containerized, the web server may not have access to the SSR bundle. To disable this check, you may set the inertia.ssr.ensure_bundle_exists configuration value to false.

​
Laravel Cloud

To run the SSR server on Laravel Cloud, you may use Cloud’s native support for Inertia SSR.

​
Laravel Forge

To run the SSR server on Forge, you may enable it via the Inertia SSR toggle in your site’s application panel. Forge will create the required daemon and, optionally, update your deploy script to restart the SSR server on each deployment.
