Making Varnish and Laravel play nice together

This package provides an easy way to work with Varnish 4 (or 5) in Laravel. It provides a route middleware that, when applied to a route, will make sure Varnish will cache the response no matter what. The package also contains a function to flush the Varnish cache from within the application.

Support us

We invest a lot of resources into creating best in class open source packages. You can support us by buying one of our paid products.

We highly appreciate you sending us a postcard from your hometown, mentioning which of our package(s) you are using. You'll find our address on our contact page. We publish all received postcards on our virtual postcard wall.

Installation

We assume that you've already installed Varnish on your server. If not read this blogpost to learn how to install it.

You can install the package via composer:

The package will automatically register itself for Laravel 5.5+.

If you are using Laravel < 5.5, you also need to add Varnish\VarnishServiceProvider to your config/app.php providers array:

Next if you use Laravel you must publish the config-file with:

and if you use Lumen, you must copy config/varnish.php file to your application config folder.

This is the contents of the published file:

In the published varnish.php config file you should set the host key to the right value.

Add the Spatie\Varnish\Middleware\CacheWithVarnish middleware to the route middlewares.

For Laravel:

If you are using Lumen, you need to load config file before route middleware definition to your bootstrap/app.php:

Finally, you should add these lines to the vcl_backend_response function in your VCL (by default this is located at /etc/varnish/default.vcl on your server):

We highly recommend using the VCL provided the varnish-5.0-configuration-templates repo made by Mattias Geniar.

Usage

Caching responses

The routes whose response should be cached should use the cacheable middleware.

The amount of minutes that Varnish should cache this content can be configured in the cache_time_in_minutes key in the laravel-varnish.php config file. Alternatively you could also use a middleware parameter to specify that value.

Behind the scenes the middleware will add an X-Cacheable and Cache-Control to the response. Varnish will remove all cookies from Laravel's response. So keep in mind that, because thelaravel_session cookie will be removed as well, sessions will not work on routes were the CacheWithVarnish middleware is applied.

Clearing cache from Varnish

There's an artisan command to flush the cache. This can come in handy in your deployment script.

Under the hood flushing the cache will call the sudo varnishadm. To make it work without any hassle make sure the command is run by a unix user that has sudo rights.

You can also do this in your code to flush the cache:
