Note:

you can use NoSQL databses with laravel by installing their packages.

Laravel doesn’t support mongoDB out of the box, you’ll have to install a third party package or create your own implementation. I’d suggest using https://github.com/jenssegers/laravel-mongodb , it seems a pretty popular package on packagist atleast. Or you could use the php mongodb class https://secure.php.net/manual/en/class.mongodb.php.
