# Bundling Assets

# Introduction

Assets in web development refer to files such as stylesheets, scripts, and images that are utilized to enhance the functionality, design, and interactivity of a web application or website. These files are essential for providing styling, behavior, and media content to the user interface.

  • CSS: Cascading Style Sheets (CSS) define the presentation and layout of HTML elements, ensuring consistent styling across pages.
  • JavaScript: JavaScript (JS) adds interactivity and dynamic behavior to web pages, enabling features like form validation, animations, and AJAX requests.
  • Images: Images enhance visual content, including logos, illustrations, and photographs, making web pages more engaging and informative.

To learn in detail about Bundling Asset, you can visit the Laravel documentation here (opens new window).

# Directory Structure

To maintain organization and manage these assets effectively, developers typically structure them within dedicated folders in the project's Resources directory. For instance:

  • /Resources/assets/css: Contains CSS files like app.css for styling the application.
  • /Resources/assets/js: Holds JavaScript files such as app.js for client-side scripting.
  • /Resources/assets/images: Stores image files used throughout the application.
  • /Resources/assets/fonts: Stores fonts used throughout the application.

Here's the updated directory structure:

└── packages
    └── Webkul
        └── Blog
            └── src
                ├── ...
                └── Resources
                    ├── ...
                    └── assets
                        ├── css
                        │   └── app.css
                        ├── js
                        │   └── app.js
                        └── images
                        └── fonts

The following JavaScript code snippet is used to track and publish all images and fonts within specified directories:

/**
 * This will track all the images and fonts for publishing.
*/
import.meta.glob(["../images/**", "../fonts/**"]);

# Explanation

  • This code utilizes the import.meta.glob() function, which is a feature in JavaScript for importing multiple modules using glob patterns.

  • "../images/**": Matches all files and directories within the images directory and its subdirectories.

  • "../fonts/**": Matches all files and directories within the fonts directory and its subdirectories.

# Configure Compiling Assets

To compile the assets, perform the following steps:

# Create Configuration Files

First, create the following configuration files in the root directory of your package, specifically inside packages/Webkul/Blog:

  • package.json
  • vite.config.js
  • postcss.config.js
  • tailwind.config.js

# Set Up package.json

Copy and paste the following code into your package.json file:

{
    "private": true,
    "scripts": {
        "dev": "vite",
        "build": "vite build"
    },
    "devDependencies": {
        "autoprefixer": "^10.4.14",
        "axios": "^1.1.2",
        "laravel-vite-plugin": "^0.7.2",
        "postcss": "^8.4.23",
        "tailwindcss": "^3.3.2",
        "vite": "^4.0.0",
        "vue": "^3.2.47"
    },
    "dependencies": {
        "@vee-validate/i18n": "^4.9.1",
        "@vee-validate/rules": "^4.9.1",
        "mitt": "^3.0.0",
        "vee-validate": "^4.9.1",
        "vue-flatpickr": "^2.3.0"
    }
}

# Explanation

The package.json file includes the following:

  • Ensures the package is private and not published to a registry.

  • Scripts

    • dev Runs the Vite development server.

    • build Builds the project for production using Vite.

  • DevDependencies: These are packages required during the development phase, including:

    • autoprefixer Adds vendor prefixes to CSS rules.
    • axios A promise-based HTTP client.
    • laravel-vite-plugin Integrates Vite with Laravel.
    • postcss A tool for transforming CSS with JavaScript plugins.
    • tailwindcss A utility-first CSS framework.
    • vite A frontend build tool.
    • vue The progressive JavaScript framework.

  • Dependencies: These are essential packages required for the project to function, including:

    • @vee-validate/i18n Internationalization for VeeValidate.
    • @vee-validate/rules Validation rules for VeeValidate.
    • mitt A tiny event emitter.
    • vee-validate Form validation for Vue.js.
    • vue-flatpickr A Vue component for Flatpickr date picker.

# Set Up vite.config.js

Copy and paste the following code into your vite.config.js file:

import { defineConfig, loadEnv } from "vite";
import laravel from "laravel-vite-plugin";
import path from "path";

export default defineConfig(({ mode }) => {
    const envDir = "../../../";

    Object.assign(process.env, loadEnv(mode, envDir));

    return {
        build: {
            emptyOutDir: true,
        },

        envDir,

        server: {
            host: process.env.VITE_HOST || "localhost",
            port: process.env.VITE_PORT || 5173,
        },

        plugins: [
            laravel({
                hotFile: "../../../public/blog-vite.hot",
                publicDirectory: "../../../public",
                buildDirectory: "themes/blog/build",
                input: [
                    "src/Resources/assets/css/app.css",
                    "src/Resources/assets/js/app.js",
                ],
                refresh: true,
            }),
        ],

        experimental: {
            renderBuiltUrl(filename, { hostId, hostType, type }) {
                if (hostType === "css") {
                    return path.basename(filename);
                }
            },
        },
    };
});

# Explanation

The vite.config.js file configures Vite for your project. Here are the key sections:

  • defineConfig A function that defines the configuration for Vite.

  • loadEnv Loads environment variables from a specific directory.

  • emptyOutDir Ensures the output directory is cleaned before building.

  • envDir Specifies the directory for environment variables.

  • host The host address for the development server.

  • port The port for the development server.

  • plugins An array of plugins used by Vite. The laravel-vite-plugin integrates Vite with Laravel.

  • experimental Experimental features, such as custom handling of built URLs for CSS.

# Set Up tailwind.config.js

Copy and paste the following code into your tailwind.config.js file:

/** @type {import('tailwindcss').Config} */
module.exports = {
    content: ["./src/Resources/**/*.blade.php", "./src/Resources/**/*.js"],

    theme: {
        extend: {}
    },

    plugins: [],
};

# Explanation

The tailwind.config.js file configures Tailwind CSS for your project:

  • content Specifies the files Tailwind should scan for class names to generate styles. In this case, it includes all Blade and JavaScript files in the src/Resources directory.

  • theme Allows customization of the default theme. The extend object is used to add or override default styles.

  • plugins An array where you can add Tailwind CSS plugins. Currently, it is empty.

By following these steps and setting up the tailwind.config.js file as shown, you’ll ensure that Tailwind CSS is properly integrated and configured in your project.

# Set Up postcss.config.js

Copy and paste the following code into your postcss.config.js file:

module.exports = {
    plugins: {
    tailwindcss: {},
    autoprefixer: {},
    },
}

# Explanation

The postcss.config.js file configures PostCSS with the following plugins:

  • tailwindcss Integrates Tailwind CSS.

  • autoprefixer Adds vendor prefixes to CSS rules to ensure cross-browser compatibility.

# Install Dependencies

Run npm install in the root of your package (packages/Webkul/Blog) to install all the dependencies.

Now, your css and js files are ready to use. You can write all your CSS and JS code here.

TIP

To watch your changes in assets, run npm run dev, and When you're done making changes, run npm run build to compile all your changes and move them into the build directory.

# Load Assets From Package

To load assets from your package, follow these steps:

# Update config/bagisto-vite.php

Add the following code to the config/bagisto-vite.php file:

'blog' => [
    'hot_file'                 => 'blog-vite.hot',
    'build_directory'          => 'themes/blog/build',
    'package_assets_directory' => 'src/Resources/assets',
],

# Explanation

The configuration array specifies how to load assets for the "blog" package:

  • hot_file Specifies the name of the Vite hot module replacement (HMR) file.
  • build_directory Indicates where the built assets will be placed.
  • package_assets_directory Points to the directory containing the package's assets.

# Load Assets in Blade File

Add the following code to your Blade file to load assets from your package:

@push('styles')
    @bagistoVite([
      'src/Resources/assets/css/app.css',
      'src/Resources/assets/js/app.js'
    ], 'blog')
@endpush

# Explanation

  • The first argument is an array of asset paths relative to the package_assets_directory.

  • The second argument is the key for the configuration array, which in this case is 'blog'.
