Adding a new disk in the storage is easy. The only things I did was:

• Copy and paste code from the documentation and made it a package (https://laravel.com/docs/filesystem#custom-filesystems)
• Use the Flysystem adapter from Spatie, which Laravel is based on (https://github.com/spatie/flysystem-dropbox)

Requirements

Laravel Dropbox Driver requires:

• PHP 8.1+
• Laravel 9+

Installation

To install Laravel Dropbox Driver, run the command below:

composer require benjamincrozat/laravel-dropbox-driver

Usage in your project

Add the following in app/filesystems.php:

'disks' => [

    'dropbox' => [
        'driver' => 'dropbox',
        'token'  => env('DROPBOX_TOKEN'),
    ],

],

Then, in your .env file:

DROPBOX_TOKEN=your_access_token

Get a token from Dropbox

Log in to your Dropbox account and create a new application to generate your access token.

License

Take this package and do whatever the f you want with it. That’s basically what the WTFPL license says.
