Laravel easyrec

Build Status Software License Latest Version

What is easyrec?

easyrec is an open source recommendation engine system that provides personalized recommendations using a RESTful API.

The recommendation engine server

You can use the server and call the associated RESTful API maintained by the easyrec team or download easyrec and call the API on one of your servers.

For additional information, take a look at the easyrec website.

Use easyrec with the server maintained by the team

This is the ready-to-go solution. You may want to use this if you don't want to configure another server dedicated to easyrec.

  • Create a easyrec account: http://easyrec.org/register
  • Open up your mailbox and activate your account
  • Create a new Tenant in your dashboard
  • Fill your API key and your Tenant ID in the configuration file

Configure your own easyrec server

Take a look at the easyrec installation guide.

Installation

PHP 5.4+ or HHVM 3.3+, and Composer are required.

To get the latest version of Laravel Easyrec, simply add the following line to the require block of your composer.json file:

"antoineaugusti/laravel-easyrec": "~1.0"

You'll then need to run composer install or composer update to download it and have the autoloader updated.

Once Laravel Easyrec is installed, you need to register the service provider. Open up config/app.php and add the following to the providers key.

  • 'Antoineaugusti\LaravelEasyrec\LaravelEasyrecServiceProvider'

You can register the Easyrec facade in the aliases key of your config/app.php file if you like.

  • 'Easyrec' => 'Antoineaugusti\LaravelEasyrec\Facades\LaravelEasyrec'

Looking for a Laravel 4 compatible version?

Checkout the 0.5.4 version, installable by requiring "antoineaugusti/laravel-easyrec": "0.5.4". You can also checkout the laravel-4 branch.

Configuration

To get started, you'll need to publish all vendor assets:

$ php artisan vendor:publish

This will create a config/easyrec.php file in your app that you can modify to set your configuration. Also, make sure you check for changes to the original config file in this package between releases.
