Laravel Page Cache

This Laravel package provides a full-page response cache middleware for stateless public GET pages. It caches 200 responses keyed by a version token, locale, and theme cookie, skips authenticated requests, exposes an X-Page-Cache HIT/MISS header, and offers a static flush() helper to invalidate every cached page at once.

Installation

You can install the package via composer:

composer require jeffersongoncalves/laravel-page-cache

You can publish the config file with:

php artisan vendor:publish --tag="laravel-page-cache-config"

This is the contents of the published config file:

return [
    'enabled' => env('PAGE_CACHE_ENABLED', true),

    'ttl' => (int) env('PAGE_CACHE_TTL', 3600),

    'key' => [
        'locale' => true,

        'theme' => [
            'enabled' => true,
            'cookie' => 'theme',
        ],
    ],
];

Usage

Register CachePublicPage as the outermost middleware on your public route group so cached responses are served before any other middleware runs:

use Illuminate\Support\Facades\Route;
use JeffersonGoncalves\PageCache\Middleware\CachePublicPage;

Route::middleware(CachePublicPage::class)->group(function () {
    Route::get('/', HomeController::class);
    Route::get('/{slug}', ShowController::class);
});

The first request to a path is computed normally and stored with an X-Page-Cache: MISS header. Subsequent requests are served straight from the cache with an X-Page-Cache: HIT header. Only stateless GET requests that return a 200 response from a guest (unauthenticated) visitor are cached.

Invalidating the cache

Call CachePublicPage::flush() from your model observers to invalidate every cached page whenever the underlying content changes:

use JeffersonGoncalves\PageCache\Middleware\CachePublicPage;

class ProjectObserver
{
    public function saved(Project $project): void
    {
        CachePublicPage::flush();
    }

    public function deleted(Project $project): void
    {
        CachePublicPage::flush();
    }
}

flush() bumps an internal version token, so every previously cached page is bypassed on the next request without touching individual cache keys.

Cache key

By default the cache key is composed of the version token, the current locale, the theme cookie value, and a hash of the request path. You can disable the locale or theme segments — or change the theme cookie name — through the config file. The path (not the full URL) is used so the query string cannot flood the cache with variants.
