laravel-plausible-proxy

A Laravel package for proxying Plausible Analytics, improving performance and privacy.

Requirements

• Laravel 12 or 13
• PHP 8.3, 8.4 or 8.5

Installation

1. Install the package via Composer:

   composer require mattitja/laravel-plausible-proxy
   

2. Publish the configuration file:

   php artisan vendor:publish --tag=plausible-proxy-config
   

3. Add the following environment variable to your .env file:

   PLAUSIBLE_DOMAIN=https://plausible.io
   

Configuration

The config/plausible-proxy.php file allows you to customize the Plausible domain:

return [
    'domain' => env('PLAUSIBLE_DOMAIN', 'https://plausible.io'),
    'script' => env('PLAUSIBLE_SCRIPT', 'js/script.js'),
];

PLAUSIBLE_SCRIPT is the path of the script on your Plausible instance. Whatever script you choose, it is always served locally from /js/script.js.

Usage

1. Proxying the JavaScript file

This package proxies Plausible's script.js while caching it to improve performance and reduce external requests.

After installation, you can include the script like this:

<script defer data-domain="example.com" src="/js/script.js"></script>

The route /js/script.js is handled automatically and caches the script for 6 hours.

Site-specific script (pa-XXXXX.js)

Plausible's current installation instructions use a site-specific script such as https://plausible.io/js/pa-12345ABCDE.js, where optional measurements (outbound links, file downloads, etc.) are configured in the Plausible dashboard. To use it, set the script path in your .env:

PLAUSIBLE_SCRIPT=js/pa-12345ABCDE.js

Then load it locally and tell it to send events through the proxy with the endpoint option:

<script async src="/js/script.js"></script>
<script>
  window.plausible=window.plausible||function(){(plausible.q=plausible.q||[]).push(arguments)},plausible.init=plausible.init||function(i){plausible.o=i||{}};
  plausible.init({ endpoint: '/api/event' })
</script>

Legacy script extensions

Legacy script variants work the same way, for example:

PLAUSIBLE_SCRIPT=js/script.outbound-links.js

2. Sending events to Plausible

The script loaded from /js/script.js sends events to /api/event on your own domain, which forwards them to Plausible. This helps prevent blocking by ad blockers.

Only the visitor's User-Agent and IP address (as X-Forwarded-For) are forwarded to Plausible, which is what Plausible needs to count unique visitors. Cookies and other request headers are never forwarded.

If your application runs behind a load balancer or reverse proxy, make sure Laravel's trusted proxies are configured so the correct visitor IP is resolved.

Upgrading from mattitjaab/laravel-plausible-proxy

Version 2.0 renames the package and its namespace:

1. Replace the package:

   composer remove mattitjaab/laravel-plausible-proxy
   composer require mattitja/laravel-plausible-proxy
   

2. If you reference any package classes directly, change the namespace from MattitjaAB\LaravelPlausibleProxy to Mattitja\LaravelPlausibleProxy.
3. Laravel 10 is no longer supported.
