HttpCache for Laravel

Laravel can use HttpKernelInterface Middlewares, so also HttpCache. This package provides a simple ServiceProvider to get you started with HttpCache.

First, require this package with composer

composer require barryvdh/laravel-httpcache

After updating, add the ServiceProvider to the array of providers in app/config/app.php

'Barryvdh\HttpCache\ServiceProvider',

You can now add the Middleware to your Kernel:

'Barryvdh\HttpCache\Middleware\CacheRequests',

Caching is now enabled, for public responses. Just set the Ttl or MaxSharedAge

Route::get('my-page', function(){
   return Response::make('Hello!')->setTtl(60); // Cache 1 minute
});

You can use the provided SetTtl middleware in your Kernel to simplify this:

protected $routeMiddleware = [
    // ...
    'ttl' => \Barryvdh\HttpCache\Middleware\SetTtl::class,
];

Route::get('my-page', function(){
   return 'Hello' 
})->middleware('ttl:60'); // Cache 1 minute

Publish the config to change some options (cache dir, default ttl, etc) or enable ESI.

$ php artisan vendor:publish --provider="Barryvdh\HttpCache\ServiceProvider"

Direct approach, without ServiceProvider

Note: This is still in beta, test with caution. It should be faster, but less flexible because it starts earlier.

You can also wrap the Kernel in the HttpCache, in your public/index.php. Replace the 'Run The Application' part like this:

$kernel = $app->make(Illuminate\Contracts\Http\Kernel::class);

$kernel = \Barryvdh\HttpCache\CacheKernel::wrap($kernel);

$response = $kernel->handle(
    $request = Illuminate\Http\Request::capture()
);

$response->send();

$kernel->terminate($request, $response);

ESI

Enable ESI in your config file and add the Esi Middleware to your Kernel:

'Barryvdh\HttpCache\Middleware\ParseEsi',

You can now define ESI includes in your layouts.

<esi:include src="<?= url('partial/page') ?>"/>

This will render partial/page, with it's own TTL. The rest of the page will remain cached (using it's own TTL)

Purging/flushing the cache

You can purge a single url or just delete the entire cache directory:

App::make('http_cache.store')->purge($url);
\File::cleanDirectory(app('http_cache.cache_dir'));

Or use the Artisan httpcache:clear command

$ php artisan httpcache:clear
