Laravel and Inertia.js: Installation Tutorial and Tips & Tricks

The future of web development lies in building sites and applications that combine robust backends with seamless user experiences. That’s where the potent association of Laravel and Inertia.js comes into play.

No more clunky page reloads, no more bloated JavaScript bundles – just good speed and user experience. That too without sacrificing the simplicity and maintainability of server-side rendering. You’ll learn how the Laravel development services integrate Laravel and Inertia.js to ensure the best performance and UX on a web app.

But first, let’s see what Inertia.js is.

What is Inertia.js?

Inertia.js is a JavaScript library designed to simplify the development of single-page applications (SPAs). It uses traditional server-side rendering and controllers to achieve so. It stays on top of your existing backend technologies and handles communication between the client and server.

• Server-Side Rendering (SSR). Inertia.js utilizes SSR for SEO benefits and faster initial page loads. Server-rendered HTML is streamed to the client, improving SEO and performance.
• API-less Data Exchange. Instead of a separate API, Inertia.js exchanges data between the server and the client. It uses JSON responses to manage the server-side controllers. This simplifies backend logic and avoids unnecessary API endpoints.
• Component-Based Architecture. Frontend functionality is organized into reusable components. These components receive data directly from the server, streamlining communication.
• Client-Side Routing Simulation. Inertia.js blocks standard anchor tag clicks and sends XHR requests to the server. The server returns a JSON response containing page component information and data, updating the DOM without a full page reload.
• Lazy Loading and Code Splitting. To boost performance, Inertia.js supports lazy loading components and splitting applications. This improves the page’s load speed.

Overall, Inertia.js bridges the gap between traditional server-side development and modern SPA needs. Similarly, it also offers a familiar approach to building dynamic and performant web applications.

How to Integrate Laravel and Inertia.js?

Building web applications requires a powerful yet approachable solution. The union of Laravel and Inertia.js works as a streamlined SPA facilitator. This guide offers a step-by-step integration process, helping you to build exceptional user experiences.

Step 1: Installation

Laying the base for Laravel and Inertia.js integration begins with installation. This step establishes the communication channels between your server-side and client-side environments.

1. Incorporating the Package. Introduce Inertia.js to your Laravel project using Composer. This command includes the Inertia.js package and its dependencies, bringing its functionalities within reach.

composer require inertia/inertia-laravel

2. Publishing Essential Assets. Unlock component and asset communication, and publish the required assets. It publishes configuration files and scripts, forming the foundation for a smooth integration.

php artisan vendor:publish --provider="Inertia\ServiceProvider"

This command executes the publish method of the Inertia\ServiceProvider. This transits the provider’s configuration and publishes specific files to your Laravel application’s public directory. It includes the Inertia JavaScript library, blade templates, and configuration files necessary for server-side communication and routing.

Step 2: Root Template

The root template serves as the central hub, coordinating the integration of Laravel and Inertia.js. Here, we’ll establish the initial structure and communication mechanisms to ensure smooth data exchange and rendering.

1. Use Existing File. Laravel’s pre-existing app.blade.php file serves as the foundation for your root template. This file inherits blade components and directives, offering a familiar and efficient base.

2. Injecting the Inertia Engine. Integrate the @inertia and @inertiaHead directives within your root template:

HTML
<head>
  @inertiaHead
</head>
<body>
  @inertia
</body>

a. The @inertiaHead demand populates head tags with information for client-side routing and component initialization.

b. The @inertia directive acts as a placeholder for injecting Inertia components, based on server-side instructions.

3. Integrate Assets. Ensure your root template references necessary CSS and JavaScript assets. This establishes the visual elements and core functionalities for your single-page application.

4. Maintain Separation. Consider creating a dedicated blade component for the @inertia placeholder. This component would house the logic for rendering the Inertia-driven content within your application.

This provides a foundational overview. For more in-depth customization and optimization. With a well-structured root template, you set the stage for building a maintainable Inertia.js application within your Laravel environment.

Step 3: Server Side Setup

The server-side setup is the core of your Laravel and Inertia.js applications. It is responsible for handling requests, routing, and rendering data.

1. Enlisting Middleware. In your App\Http\Kernel file, locate the web middleware group and register the HandleInertiaRequests middleware:

protected $middlewareGroups = [
    'web' => [
        // ... other middleware
        Inertia\Middleware\ShareInertiaData::class,
        Inertia\Middleware\HandleInertiaRequests::class,
    ],
];

This middleware handles Inertia-specific requests. Using this you can enable smooth communication between your routes and client-side components.

2. Controller. Create a dedicated controller responsible for handling Inertia requests. Laravel’s routing mechanism maps paths to appropriate controller methods, ensuring organized data delivery.

3. Data. Within your controller methods, utilize Inertia’s response methods to return necessary data and component information:

public function show(Request $request)
{
    // Fetch data, perform logic
    return Inertia::render('Welcome', [
        'data' => $yourData,
        'props' => [
            'user' => auth()->user(),
        ],
    ]);
}

The Inertia::render method constructs the response. It specifies the component to render and provide data.

With a robust server-side foundation, your Laravel application is now equipped to handle requests and deliver data. This architecture ensures communication, data management, and routing.

Step 4: Client Side Setup

Now, let’s shift focus to the client side, where the magic of Inertia truly comes alive. This step involves setting up the Inertia library and initializing communication with your Laravel backend, creating a seamless bridge for data exchange and component rendering.

1. Framework-Specific Adapter. Choose your preferred JavaScript framework (React, Vue, Svelte) and install the Inertia adapter:

npm install @inertiajs/react @inertiajs/inertia

Replace @inertiajs/react with your chosen framework’s adapter. This adapter provides the necessary glue between your framework and Inertia.js.

2. Initialization. In your main JavaScript file, initialize Inertia with configuration options. This establishes the connection and sets up basic communication protocols.

import Inertia from '@inertiajs/inertia'
Inertia.init({
    // Initial page component,
    // shared data, etc.
})

3. Component Resolution. Define a function to resolve component names based on server responses. This tells Inertia which component to render based on the server-provided name.

const resolveComponent = name => require(`./components/${name}`).default

4. Routing Simulation. Use Inertia’s Link component or other methods to simulate router-like behavior. It triggers Inertia requests to the server, updating the page without full reloads.

<a href="/home" @click="inertia.visit('/home')" />

5. Client-Side Data Handling. Access data passed from the server within components. You can do so by using props or state management solutions based on your framework.

Remember, this is a high-level overview. Each framework and project setup might have specific nuances. Explore framework-specific guides for detailed instructions and advanced configuration options.

Step 5: Routing

Laravel routing plays a crucial role in directing users to the right content and ensuring a seamless flow within your applications. Let’s explore the key steps for establishing efficient and maintainable routing:

1. Server-Side Routes. Define routes within your Laravel controllers using familiar Laravel syntax:

Route::get('/', function () {
    return Inertia::render('Home');
});
Route::get('/profile', function () {
    return Inertia::render('Profile', [
        'user' => auth()->user(),
    ]);
});

2. Component Resolution. Within your controller methods, the Inertia::render method specifies the component to render (located in your client-side code). Optionally, pass necessary data as an array to be accessible within the component.

3. Client-Side Navigation. Use Inertia’s Link component or framework-specific methods to trigger navigation:

<a href="/profile" @click="inertia.visit('/profile')" />

These mechanisms send requests to the server. Then it retrieves the updated HTML and component information, and updates the browser without full page reloads.

4. Route Parameters. Capture segments in Laravel routes and access them in your controller logic. Pass captured parameters to your components for tailored content and functionality.

Route::get('/posts/{id}', function ($id) {
    // Fetch post data based on $id
    return Inertia::render('Post', [
        'post' => $post,
    ]);
});

5. Named Routes (Optional). Leverage Laravel’s named routes for convenience and maintainability:

Route::get('/profile', function () {
    return Inertia::render('Profile', [
        'user' => auth()->user(),
    ]);
})->name('profile');

Use the route function from your client-side framework to generate URLs based on named routes:

<a href="{{ route('profile') }}" @click="inertia.visit(route('profile'))" />

A well-defined routing strategy empowers your Laravel and Inertia.js applications to guide users with precision. Each route acts as a roadmap It directs requests to the appropriate server-side logic and renders the corresponding component on the client side.

Step 6: Sharing Data

Data is lifeblood in any application, and Inertia.js offers multiple ways to exchange information between your Laravel backend and JavaScript frontend. Let’s explore the common approaches:

1. Component Props. Pass data directly from your Laravel controller to specific components using the Inertia::render method:

return Inertia::render('Profile', [
    'user' => auth()->user(),
    'posts' => $user->posts,
]);

This data is then accessible within the corresponding component’s props object.

2. Global Data Sharing. Use Inertia::share to make data accessible across all pages. This data is available within any component using a framework-specific mechanism (e.g., using a global store in Vue).

Inertia::share('appVersion', config('app.version'));

3. Messages. Leverage Inertia’s flash message system to display temporary messages across page transitions. These messages are accessible within components and can be displayed or dismissed as needed.

return Inertia::render('Home', [
    'flash' => [
        'message' => 'Your profile has been updated successfully!',
    ],
]);

4. Laravel Flash Session. Alternatively, utilize Laravel’s built-in flash session mechanism. Access this data within your component using framework-specific methods (e.g., using $flash in Vue).

5. API-like Requests. For complex data fetching scenarios, consider using API-like requests within your components. This allows for more granular data retrieval and manipulation on the client side.

Inertia.get('/api/posts')
    .then(response => {
        // Handle response data
    });

With effective data sharing, your Laravel and Inertia.js applications deliver personalized experiences. It also benefits in displaying relevant information and maintaining user context across interactions. With a solid understanding of data sharing, you can build an application that connects and engages your users.
