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

Goals: * 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 and frameworks. * Be cacheable. * Emulate directories in systems that support none, like AwsS3. * Support third party plugins. * Make it easy to test your filesystem interactions. * Support streams for big file handling.
