4 Common Vite Errors in Laravel

Leveraging Vite to streamline frontend asset building in your Laravel application offers significant advantages. However, initial setup can present challenges. This article addresses four common Vite-related errors encountered when integrating Vite with Laravel, providing solutions to accelerate your development workflow.

Error 1: Vite manifest not found at: public/build/manifest.json

This error, encountered during page loading, indicates the Laravel Vite plugin can't locate the manifest.json file—a crucial component mapping source files to their Vite-processed counterparts.

Solution:

• Default Configuration: If you haven't modified your package.json, simply run npm run dev (development) or npm run build (production) to regenerate the manifest.json file within the public/build directory.

• Customized Configuration: Altering your vite.config.js (e.g., changing the buildDirectory to dist), necessitates adjusting your Blade views. Instead of @vite('resources/css/app.css'), use:

{{ Vite::useBuildDirectory('dist')->withEntryPoints(['resources/css/app.css', 'resources/js/app.js']) }}

This explicitly directs the plugin to the correct manifest.json location.

Error 2: Unable to locate file in Vite manifest: resources/sass/app.scss

This signifies Vite's inability to find the file specified in your Blade @vite directive.

Solution:

1. Verify Filepath and Existence: Double-check the file path in your Blade template for accuracy and ensure the file (resources/sass/app.scss or similar) exists. Typos are common culprits.

2. Regenerate the Manifest: Run npm run dev or npm run build to refresh the manifest.json file, potentially resolving discrepancies between your code and the manifest.

3. Confirm Vite Processing: Inspect public/build/manifest.json. The file you're including (resources/sass/app.scss) should be listed under a src property entry. If absent, your vite.config.js's input array might need updating to include the file's path:

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

export default defineConfig({
    plugins: [
        laravel({
            input: ['resources/sass/app.scss', 'resources/js/app.js'], // Add or correct path here
            refresh: true,
        }),
    ],
});

Error 3: Uncaught ReferenceError: $ is not defined (Using jQuery)

This error arises when using jQuery's $ without proper inclusion.

Solution:

1. Verify jQuery Installation: Use npm list jquery to check if jQuery is installed. If not, install it using npm install jquery -D.

2. Ensure jQuery Import: Import jQuery into your JavaScript files where you utilize the $ variable. For example, in resources/js/app.js or directly within the file using jQuery. Alternatively, assign $ to the window object in your main JS file (e.g., app.js) to make it globally accessible.

Error 4: vite: Permission denied

This typically stems from insufficient permissions, often resulting from using sudo npm install.

Solution:

Recursively change the ownership of the node_modules directory to your user account. Replace your_username with your actual username:

{{ Vite::useBuildDirectory('dist')->withEntryPoints(['resources/css/app.css', 'resources/js/app.js']) }}

Conclusion:

This guide provides practical solutions to common Vite integration issues within Laravel. Remember to consistently verify file paths, regenerate manifests, and ensure proper dependency management for a smooth development process. Utilizing error monitoring tools like Sentry can further enhance debugging efficiency.
