Installation

To install the Laravel Optimizer package, run the following command in your project's root directory:

composer require caujasutom/laravel-optimizer

After installing the package, publish the configuration file by running the following command:

php artisan vendor:publish --provider="Caujasutom\LaravelOptimizer\LaravelOptimizerServiceProvider"

Configuration

The configuration file config/laravel_optimizer.php contains the default settings for the package. You can modify these settings to suit your needs.

<?php
return [
// Time-to-live for static cache in minutes.
'static_cache_ttl' => env('LARAVEL_OPTIMIZER_STATIC_CACHE_TTL', 60),

    // Path for storing cache files.
    'cache_path' => env('LARAVEL_OPTIMIZER_CACHE_PATH', 'static_cache/'),

    // Compression level for gzip (0-9).
    'compression_level' => env('LARAVEL_OPTIMIZER_COMPRESSION_LEVEL', 9),

    // Gzip compression settings
    'gzip_compression' => [
        'level' => env('LARAVEL_OPTIMIZER_GZIP_COMPRESSION_LEVEL', 9), // Default compression level for Gzip.
    ],

    // Minification settings
    'minification' => [
        'enabled' => env('LARAVEL_OPTIMIZER_MINIFICATION_ENABLED', true),
        'patterns' => [
            '/>\s+/s',
            '/\s+\s+',
            '/[\r\n]+/'
        ],
        'replacements' => [
            '>',
            '<',
            '\\1',
            '><',
            ''
        ],
    ],
];

Middlewares

1. HTML Minify Middleware

The HtmlMinifyMiddleware minifies HTML content by removing unnecessary whitespace and line breaks. To use this middleware, add it to your app/Http/Kernel.php file.

protected $middlewareGroups = [
    'web' => [
        // ...
        \Caujasutom\LaravelOptimizer\Middleware\HtmlMinifyMiddleware::class,
    ],
];

2. Static HTML Cache Middleware

The StaticHtmlCacheMiddleware caches the generated HTML content for a specified duration. To use this middleware, add it to a specific route or route group in your routes/web.php file.

Route::middleware(['static.html.cache:60'])
    ->group(function () {
        Route::get('/', 'HomeController@index');
});

The number (60 in the example above) represents the cache duration in minutes. Adjust this value as needed.

3. Gzip Compression Middleware

The GzipCompressionMiddleware compresses the response content using Gzip compression. To use this middleware, add it to your app/Http/Kernel.php file.

protected $middlewareGroups = [
    'web' => [
        // ...
        \Caujasutom\LaravelOptimizer\Middleware\GzipCompressionMiddleware::class,
    ],
    // ...
];

Helpers

The package provides helper functions to simplify the use of the StaticHtmlCache class. The following functions are available:

LaravelOptimizer::cache()->store()

Stores the generated HTML content for the given URL.

LaravelOptimizer::cache()->store($url, $content, $minutes = null);

Parameters:

LaravelOptimizer::cache()->retrieve($url)

Retrieves the cached HTML content for the given URL.

LaravelOptimizer::cache()->retrieve($url);

Parameters:

Returns:

LaravelOptimizer::cache()->delete($url)

Deletes the cached HTML content for the given URL.

LaravelOptimizer::cache()->delete($url);

Parameters:

Examples

<?php

namespace App\Http\Controllers;

use Caujasutom\LaravelOptimizer\Facades\LaravelOptimizer;
use Illuminate\Http\Request;
use Illuminate\Support\Facades\View;

class ArticlesController extends Controller
{
    /**
     * Display a listing of articles.
     *
     * @return \Illuminate\Http\Response
     */
    public function index()
    {
        // Check if cached HTML content exists for this URL
        $cachedContent = LaravelOptimizer::cache()->retrieve(request()->url());
        if ($cachedContent) {
            // If cached content exists, return it
            return response($cachedContent);
        } else {
            // If cached content doesn't exist, generate and cache new content
            $articles = Post::all(); // Fetch articles from the database or any other source
            
            // Render the articles view
            $htmlContent = View::make('articles.index', ['articles' => $articles])->render();
            
            // Cache the generated HTML content for this URL
            LaravelOptimizer::cache()->store(request()->url(), $htmlContent);
            
            return response($htmlContent);
        }
    }
}

In this example, we have an ArticlesController with an index function. This function is responsible for displaying a listing of articles.

Here's the breakdown of the function:

1. First, it checks if there is cached HTML content available for the current URL using the LaravelOptimizer::cache()->retrieve(request()->url()) method.
2. If cached content exists, it returns the cached HTML content as the response.
3. If cached content doesn't exist, it fetches the articles from the database or any other source.
4. It then renders the articles.index view with the fetched articles using View::make() and render() methods.
5. The generated HTML content is stored in the variable $htmlContent.
6. The generated HTML content is cached using LaravelOptimizer::cache()->store(request()->url(), $htmlContent) method.
7. Finally, it returns the generated HTML content as the response.
