PHP Laravel Vite: A Comprehensive Guide

Laravel is a popular PHP framework known for its elegant syntax and powerful tools. With the release of Laravel 9, a new build tool called Vite was introduced to handle frontend asset compilation and management. Vite, which means “fast” in French, is designed to be an extremely fast and modern build tool that offers a better developer experience.

In this comprehensive guide, we will explore Laravel Vite, its features, and how to integrate it into your Laravel projects. We will cover the basics of Vite, how it compares to previous tools like Laravel Mix, and delve into advanced configuration and usage.

Introduction to Vite

Vite is a build tool that aims to provide a faster and leaner development experience for modern web projects. It leverages the native ES modules in the browser to provide instant server start and lightning-fast hot module replacement (HMR) during development. Vite also bundles your code with Rollup, which is highly optimized for production.

Key Features of Vite

Instant Server Start: Vite uses native ES modules to serve your code, allowing for instant server start regardless of the size of your application.
Lightning-Fast HMR: Vite provides fast hot module replacement, enabling you to see changes almost instantly without refreshing the page.
Optimized Build: Vite uses Rollup for bundling your code in production, offering optimized and minified output.
Out-of-the-Box Support: Vite has built-in support for popular frontend frameworks like Vue, React, and Svelte.

Integrating Vite with Laravel

Laravel Vite simplifies the process of integrating Vite into your Laravel projects. Laravel Vite replaces Laravel Mix and provides a streamlined approach to handling frontend assets.

Installation

To get started with Laravel Vite, you need to install the necessary packages. First, install the Laravel Vite package via Composer:

composer require laravel/vite-plugin

Next, install the Vite package and any other necessary frontend dependencies using npm or Yarn:

npm install

Configuration

After installing the necessary packages, you need to configure Vite to work with Laravel. Create a vite.config.js file in the root of your project:

import { defineConfig } from 'vite';
import laravel from 'laravel-vite-plugin';

export default defineConfig({
    plugins: [
        laravel([
            'resources/css/app.css',
            'resources/js/app.js',
        ]),
    ],
});

In this configuration file, we import the laravel-vite-plugin and define the entry points for your CSS and JavaScript files. These entry points are typically located in the resources directory of your Laravel project.

Using Vite in Laravel Views

To include the compiled assets in your Laravel views, you can use the @vite Blade directive. Open your resources/views/layouts/app.blade.php file and add the following lines:

<!DOCTYPE html>
<html lang="{{ str_replace('_', '-', app()->getLocale()) }}">
<head>
    <!-- Include Vite CSS -->
    @vite('resources/css/app.css')
</head>
<body>
    <!-- Include Vite JS -->
    @vite('resources/js/app.js')

    <!-- Your content here -->
    @yield('content')
</body>
</html>

The @vite directive ensures that the correct asset paths are included in your views.

Running Vite

With the configuration in place, you can now run Vite in development mode or build your assets for production.

Development Mode

To start the Vite development server with hot module replacement, run:

npm run dev

This command starts the Vite server, and you can access your application at http://localhost:3000.

Production Build

To build your assets for production, run:

npm run build

This command bundles your assets using Rollup and places the optimized output in the public/build directory.

Advanced Configuration

Vite offers a range of advanced configuration options to tailor the build process to your needs.

Environment Variables

Vite supports environment variables, which can be defined in .env files. These variables are loaded into the process.env object. For example, you can create a .env file with the following content:

VITE_APP_TITLE=My Laravel Vite App

You can then access this variable in your JavaScript code:

console.log(import.meta.env.VITE_APP_TITLE);

Aliases

You can define path aliases in your vite.config.js file to simplify module imports:

import { defineConfig } from 'vite';
import laravel from 'laravel-vite-plugin';
import { resolve } from 'path';

export default defineConfig({
    plugins: [
        laravel([
            'resources/css/app.css',
            'resources/js/app.js',
        ]),
    ],
    resolve: {
        alias: {
            '@': resolve(__dirname, 'resources/js'),
        },
    },
});

With this configuration, you can import modules using the @ alias:

import MyComponent from '@/components/MyComponent.vue';

Plugins

Vite’s plugin system is built on Rollup, allowing you to use a wide range of Rollup plugins. You can add plugins to your vite.config.js file:

import { defineConfig } from 'vite';
import laravel from 'laravel-vite-plugin';
import vue from '@vitejs/plugin-vue';

export default defineConfig({
    plugins: [
        laravel([
            'resources/css/app.css',
            'resources/js/app.js',
        ]),
        vue(),
    ],
});

CSS Preprocessors

Vite supports CSS preprocessors like Sass, Less, and Stylus. To use Sass, for example, you need to install the sass package:

npm install sass

Then, you can import your Sass files in your JavaScript entry point:

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

TypeScript

Vite has first-class support for TypeScript. To use TypeScript in your project, install the necessary packages:

npm install typescript @types/node

You can then create TypeScript files (.ts or .tsx) and import them in your project. Ensure your tsconfig.json file is properly configured:

{
    "compilerOptions": {
        "target": "esnext",
        "module": "esnext",
        "moduleResolution": "node",
        "strict": true,
        "jsx": "preserve",
        "esModuleInterop": true,
        "skipLibCheck": true,
        "forceConsistentCasingInFileNames": true,
        "baseUrl": ".",
        "paths": {
            "@/*": ["resources/js/*"]
        }
    },
    "include": ["resources/js/**/*"],
    "exclude": ["node_modules"]
}

Using Vite with Vue.js

Vite has built-in support for Vue.js, making it easy to integrate Vue components into your Laravel application.

Installing Vue

First, install the necessary Vue packages:

npm install vue @vitejs/plugin-vue

Configuring Vite for Vue

Update your vite.config.js file to include the Vue plugin:

import { defineConfig } from 'vite';
import laravel from 'laravel-vite-plugin';
import vue from '@vitejs/plugin-vue';

export default defineConfig({
    plugins: [
        laravel([
            'resources/css/app.css',
            'resources/js/app.js',
        ]),
        vue(),
    ],
});

Creating Vue Components

Create a Vue component in the resources/js/components directory:

<template>
    <div>
        <h1>{{ message }}</h1>
    </div>
</template>

<script>
export default {
    data() {
        return {
            message: 'Hello, Vue with Laravel Vite!'
        };
    }
};
</script>

Using Vue Components

In your resources/js/app.js file, register and mount your Vue component:

import { createApp } from 'vue';
import ExampleComponent from './components/ExampleComponent.vue';

createApp({
    components: {
        ExampleComponent
    }
}).mount('#app');

In your Blade view, add an element with the id="app":

<div id="app">
    <example-component></example-component>
</div>

@vite('resources/js/app.js')

Best Practices for Using Laravel Vite
