Laravel and Svelte with Inertia

dansvel profile image dan Originally published at Updated on ・3 min read

It started with getting to know Svelte and her beauty, then fell in love at first sight. Ehm... But I wasn't ready if I had to bring it together with Sapper, which was meant to be.

So after searching here and there, trying all the ways that I found in the virtual universe. I met with Inertia.

What is Inertia?

Inertia allows you to create Single-page Apps (SPA) without the need to build an API. Which means you don't need to bother with complicated things like routing and API.

As far as I am concerned, all APIs and routing will still use server-side, which will be directed to the Inertia adapter. Then Inertia turns it into an XHR request and throws it to the client side.

The wedding

Inertia can be used for almost all back end such as Rails, Symfony, Yii2. Supported front-ends are, React, Vue. And other frameworks whose adapters are developed by the community.

But this time I will only marry Laravel and Svelte off here.

Server Side

  1. Prepare the Laravel application, or use what you already have.
laravel new application
application cd
Enter fullscreen mode Exit fullscreen mode
  1. Add inertia using a composer.
composer require inertiajs/inertia-laravel
Enter fullscreen mode Exit fullscreen mode
  1. Set Laravel Blade to run Inertia.


<! DOCTYPE html>
   <meta charset = "utf-8" />
   <meta name = "viewport" content = "width = device-width, initial-scale = 1.0, maximum-scale = 1.0" />
   <link href = "{{mix ('/ css/app.css')}}" rel = "stylesheet" />
   <script src = "{{mix ('/ js/app.js')}}" defer> </script>
Enter fullscreen mode Exit fullscreen mode
  1. Asset Versioning



App\Providers namespace;

use Illuminate\Support\ServiceProvider;
use Inertia\Inertia;

the AppServiceProvider class extends ServiceProvider
    public function register ()

    public boot function ()
        Inertia :: version (function () {
            return md5_file (public_path ('mix-manifest.json'));
Enter fullscreen mode Exit fullscreen mode

Client Side

  1. Add the required packages
npm install @ inertiajs/inertia @ inertiajs/inertia-svelte
npm install @ babel/plugin-syntax-dynamic-import laravel-mix-svelte
Enter fullscreen mode Exit fullscreen mode
  1. Code splitting is commonly used by frameworks, you need babel for this.

create the .babelrc file it contains

  "plugins": ["@ babel/plugin-syntax-dynamic-import"]
Enter fullscreen mode Exit fullscreen mode
  1. Initialize main JavaScript


import {InertiaApp} from '@ inertiajs/inertia-svelte'

const app = document.getElementById ('app')

new InertiaApp ({
  target: app,
  props: {
    initialPage: JSON.parse (,
    resolveComponent: name => import (`./Pages/$ {name} .svelte`) .then (module => module.default),
Enter fullscreen mode Exit fullscreen mode
  1. Configure script building   I use laravel-mix plus laravel-mix-svelte


const mix = require ('laravel-mix');
require ('laravel-mix-svelte');

mix.js ('resources/js/app.js', 'public/js')
    .sass ('resources/sass/app.scss', 'public/css')
    .svelte ({
        dev:! mix.inProduction ()
    .webpackConfig ({
        output: {chunkFilename: 'js/[name]. js? id = [chunkhash]'},
    .version ();
Enter fullscreen mode Exit fullscreen mode

Use Laravel and Svelte

For the Svelte section, you can create a view with the extension .svelte in theresources/js/Pages directory according to what was set in the initialization. Such as resources/js/Pages/Books/Show.svelte


let name = 'world';

h1 {
    color: indigo;
    font-family: 'Calibri', cursive;
    font-size: 3em;

<h1> Svelte greets {name} through inertia </h1>
Enter fullscreen mode Exit fullscreen mode

Then in the Laravel section, you can create a router to render its view or process data in the controller as usual. Don't forget to add use Inertia\Inertia; at the top of the controller


Route :: get ('/', function () {
return Inertia\Inertia :: render ('Index');
Enter fullscreen mode Exit fullscreen mode

Thank you for this post.
I'm learning both Laravel and Svelte and Inertia seems like a good fit.

actually, i have a sample project,, it's just proof of concept though,,
something like voting app, but the readme and content in Bahasa Indonesia,, however you can just copy-paste to google translate :)
