Flysystem is a filesystem abstraction which allows you to easily swap out a local filesystem for a remote one.

• Have a generic API for handling common tasks across multiple file storage engines.
• Have consistent output which you can rely on.
• Integrate well with other packages/frameworks.
• Be cacheable.
• Emulate directories in systems that don't support them, like AWS S3.
• Support third party plugins.
• Make it easy to test your filesystem interactions.
• Support streams for big file handling.

composer require league/flysystem
