YAZ Query Builder

Installation Laravel

Dependencies

medlib/marcxml

You can install this package by using Composer, running this command:

    composer require medlib/yaz

The next required step is to add the service provider to config/app.php :

'providers' => [
    ...
    Medlib\Yaz\Providers\YazServiceProvider::class,
    Medlib\MarcXML\Providers\ParserServiceProvider::class,
]

'aliases' => [
    ...
    'Yaz' => Medlib\Yaz\Facades\Yaz::class,
    'Query' => Medlib\Yaz\Facades\Query::class,
    'MarcXML' => Medlib\MarcXML\Facades\MarcXML::class,
]

Publish

The last required step is to publish views and assets in your application with :

    php artisan vendor:publish

If you get the error

    Nothing to publish for tag []!

Then run this command :

    php artisan config:clear
