Laravel 5 and above

Installation

Add RobBrazier/Piwik to composer.json:

composer require "robbrazier/piwik=~4.2"

For Laravel 5.4 and below

Add 'RobBrazier\Piwik\PiwikServiceProvider' and 'Piwik' => 'RobBrazier\Piwik\Facades\Piwik' to app/config/app.php

'providers' = [
    ...
    RobBrazier\Piwik\PiwikServiceProvider::class,
    ...
],

[...]

'aliases' = [
    ...
    'Piwik' => RobBrazier\Piwik\Facades\Piwik::class,
    ...
],

For Laravel 5.5 and above, no app.php changes are required as the autoloader will pick up the required configuration

Then move the config file out of the package, so that it doesn't get replaced when you update, by running:

php artisan vendor:publish --provider="RobBrazier\Piwik\PiwikServiceProvider" --tag="config"

Update your packages with composer update or install with composer install.

Then go to config/piwik.php and add your config settings such as server, apikey, siteid etc.
