Vite with Laravel

∙ 6 min. read ∙ #laravel #vite #frontend #buildtools

I’ve had an eye on Vite for a while. With a stable release out the door (2.0, as 1.0 never left the release candidate stage) it seemed like a good time to give it a shot.

Vite is a frontend build tool like webpack. Instead of bundling development assets, Vite serves native ES modules transpiled with esbuild from the dev server. This means there’s a lot less bundling to do, and results in a very fast developer experience. For production builds, Vite uses Rollup to bundle the assets.

If you want to delve deeper into Vite’s background, check out Why Vite in their docs. Now, let’s dive into Laravel.

After adding Vite to a JavaScript-heavy Laravel project we’re working on, we saw:

  • Faster dev server startupnpm run hot went from 15s to <1s
  • Faster production buildsnpm run production went from from 18s to 15s
  • A lot less config & dependencies — Coming from Webpack (without Laravel Mix) the PR for Vite counts +577 −3,367 lines
  • Additional develop experience improvements — Auto-refresh when Blade files change

This post dives into a basic Vite setup for Laravel. There are also follow-up posts for Blade, Tailwind, Vue, React, TypeScript, and Inertia.

Before getting started, consider not configuring this yourself. innocenzi/laravel-vite is an off the shelf solution to add Vite to your Laravel application. If you prefer full ownership over your build tools (like me), or want to learn more about the inner workings, do carry on.


First, clean up Laravel’s default package.json by getting rid of all Laravel Mix dependencies.

      "private": true,
      "scripts": {
-         "dev": "npm run development",
-         "development": "mix",
-         "watch": "mix watch",
-         "watch-poll": "mix watch -- --watch-options-poll=1000",
-         "hot": "mix watch --hot",
-         "prod": "npm run production",
-         "production": "mix --production"
      "devDependencies": {
          "axios": "^0.21",
-         "laravel-mix": "^6.0.6",
          "lodash": "^4.17.19",
-         "postcss": "^8.1.14"

Next, install Vite.

npm i vite --dev

Back in package.json, add the necessary scripts.

      "private": true,
      "scripts": {
+         "dev": "vite",
+         "production": "vite build"
      "devDependencies": {
          "axios": "^0.21",
          "lodash": "^4.17.19",
          "vite": "^2.1.0"

Vite configuration

Create a vite.config.js file in the project root. Here’s the basic configuration for a Laravel app.

// vite.config.js
export default ({ command }) => ({
    base: command === 'serve' ? '' : '/build/',
    publicDir: 'fake_dir_so_nothing_gets_copied',
    build: {
        manifest: true,
        outDir: 'public/build',
        rollupOptions: {
            input: 'resources/js/app.js',

build.rollupOptions.input should point to the main input of our app. Important! This should only be a script. Stylesheets should be imported from the script, otherwise they won’t appear in manifest.json.

build.manifest generates a manifest.json file our Laravel app will read to discover the asset file names.

build.outDir determines where the final build will en up. In a Laravel app, this must be in the public directory. I recommend a subdirectory like public/build to make it easier to .gitignore.

Because we modified the outDir, we need to configure base. This ensures all of the path references in the files Vite generates will also point to /build/. On the development server (command === 'serve'), assets are served from http://localhost:3000. Because outDir isn’t used on the development server, we shouldn’t override base.

All files in publicDir get copied over to the outDir on build. This is how Vite deals with static assets in a SPA. Since we already have Laravel’s public directory, this isn’t relevant to us. Unfortunately there’s no way to disable this, so we’ll provide a fake path so nothing gets copied.

Before moving on to the Laravel configuration, we need to make some changes to the default app.js file.

  • As mentioned, CSS should be imported from JavaScript
  • Replace all require statements with import, as Vite requires us to use ES modules
  • Import Vite’s dynamic import polyfill
// resources/js/app.js
import 'vite/dynamic-import-polyfill';

import '../css/app.css';

import './bootstrap';

The bootstrap.js file also has some requires that need to be reworked.

+ import _ from 'lodash';
+ import axios from 'axios';
- window._ = require('lodash');
+ window._ = _;
   * We'll load the axios HTTP library which allows us to easily issue requests
   * to our Laravel back-end. This library automatically handles sending the
   * CSRF token as a header based on the value of the "XSRF" token cookie.
- window.axios = require('axios');
+ window.axios = axios;
  window.axios.defaults.headers.common['X-Requested-With'] = 'XMLHttpRequest';
   * Echo exposes an expressive API for subscribing to channels and listening
   * for events that are broadcast by Laravel. Echo and event broadcasting
   * allows your team to easily build robust real-time web applications.
  // import Echo from 'laravel-echo';
+ // import Pusher from 'pusher-js';
- // window.Pusher = require('pusher-js');
+ // window.Pusher = Pusher;
  // window.Echo = new Echo({
  //     broadcaster: 'pusher',
  //     key: process.env.MIX_PUSHER_APP_KEY,
  //     cluster: process.env.MIX_PUSHER_APP_CLUSTER,
  //     forceTLS: true
  // });

All configured!

If we run npm run dev, the dev server should start at http://localhost:3000. If we run npm run production a bundle should generate in public/build.

Laravel configuration

With the build pipeline up and running, it’s time to load the assets in the application.

First the dev server. When we run npm run dev, Vite spins up a dev server with hot module replacement enabled on localhost:3000.

To load our app, load Vite’s runtime, then create a module script tag that points to our entry filename on localhost:3000.

<script type="module" src="http://localhost:3000/@vite/client"></script>
<script type="module" src="http://localhost:3000/resources/js/app.js"></script>

When we run npm run production we need to find the exact asset path in the manifest, generated at public/build/manifest.json.

  "resources/js/app.js": {
    "file": "assets/app.e8ed53e0.js",
    "src": "resources/js/app.js",
    "isEntry": true,
    "imports": [
    "css": [
  "_vendor.0c0b30aa.js": {
    "file": "assets/vendor.0c0b30aa.js"

This requires a few more steps:

  • Read the manifest.json file
  • Extract the script location and render a script element
  • Extract the stylesheet location and render a link element
    $manifest = json_decode(file_get_contents(public_path('build/manifest.json')), true);
<script type="module" src="/build/{$manifest['resources/js/app.js']['file']}"></script>
<link rel="stylesheet" href="/build/{$manifest['resources/js/app.js']['css'][0]}">

Don’t forget to prefix the path with the base path!

To ensure the right assets are loaded in every environment, combine the previous snippets with an @production directive.

        $manifest = json_decode(file_get_contents(public_path('build/manifest.json')), true);
    <script type="module" src="/build/{$manifest['resources/js/app.js']['file']}"></script>
    <link rel="stylesheet" href="/build/{$manifest['resources/js/app.js']['css'][0]}">
    <script type="module" src="http://localhost:3000/@vite/client"></script>
    <script type="module" src="http://localhost:3000/resources/js/app.js"></script>

Better DX for non-frontend developers

The above setup forces you to run npm run dev and watch on local. However, often backend developers working on the application don’t need to watch the assets for changes.

Devs can run npm run production to generate assets once, but the application will still try to load assets from locahost:3000. The production check we have in place isn’t enough.

To work around this, we can ping localhost:3000. If it connects, we know the dev server is running and we can render the hot scripts.

First, let’s extract the code we had written in our Blade template to a helper function. Next, we’ll use Laravel Http facade to ping localhost:3000. If it connects, we know the dev server is running.


use Illuminate\Support\Facades\Http;
use Illuminate\Support\HtmlString;

function vite_assets(): HtmlString
    $devServerIsRunning = false;
    if (app()->environment('local')) {
        try {
            $devServerIsRunning = true;
        } catch (Exception) {
    if ($devServerIsRunning) {
        return new HtmlString(<<<HTML
            <script type="module" src="http://localhost:3000/@vite/client"></script>
            <script type="module" src="http://localhost:3000/resources/js/app.js"></script>
    $manifest = json_decode(file_get_contents(
    ), true);
    return new HtmlString(<<<HTML
        <script type="module" src="/build/{$manifest['resources/js/app.js']['file']}"></script>
        <link rel="stylesheet" href="/build/{$manifest['resources/js/app.js']['css'][0]}">

Finally, echo the assets in our application’s layout template.

{{ vite_assets() }}

Ready to go! Vite is set up in our Laravel application. The next step is to add additional configuration based on the tooling we’ll use.
