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.
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.
Also make sure that the execution_type
is set to socket if you would like to use this command
to flush the cache of a remote Varnish server. Set execution_type
to command to use varnishadm
on the local system.
In case you've set the execution_type
to socket, you can either store the administrative secret
in a file and set administrative_secret
, as used by varnishadm
, or provide the actual
secret string in the administrative_secret_string
variable.
Add the DeltaBlue\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.
If execution_type
is set to command, 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:
