flysystem-bundle

flysystem-bundle is a Symfony bundle integrating the Flysystem library into Symfony applications.

It provides an efficient abstraction for the filesystem in order to change the storage backend depending on the execution environment (local files in development, cloud storage in production and memory in tests).

Note: you are reading the documentation for flysystem-bundle 3.0, which relies on Flysystem 3.
If you use Flysystem 1.x, use flysystem-bundle 1.x.
If you use Flysystem 2.x, use flysystem-bundle 2.x.
Read the Upgrade guide to learn how to upgrade.

Installation

flysystem-bundle 3.x requires PHP 8.0+ and Symfony 5.4+.

If you need support for a lower PHP/Symfony version, consider using flysystem-bundle 2.x which support Flysystem 3.x and older PHP/Symfony versions.

You can install the bundle using Symfony Flex:

composer require league/flysystem-bundle

Basic usage

The default configuration file created by Symfony Flex provides enough configuration to use Flysystem in your application as soon as you install the bundle:

# config/packages/flysystem.yaml

flysystem:
    storages:
        default.storage:
            local:
                directory: '%kernel.project_dir%/var/storage/default'

This configuration defines a single storage service (default.storage) based on the local adapter and configured to use the %kernel.project_dir%/var/storage/default directory.

For each storage defined under flysystem.storages, an associated service is created using the name you provide (in this case, a service default.storage will be created). The bundle also creates a named alias for each of these services.

This means you can inject the storage services in your services and controllers like this:

1) Using service autowiring: typehint your service/controller argument with FilesystemOperator and use the #[Target] attribute to select the storage by name:

use League\Flysystem\FilesystemOperator;

class MyService
{
    public function __construct(
        #[Target('default.storage')] private FilesystemOperator $storage,
    ) {
    }

    // ...
}

Instead of using the #[Target] attribute, you can also typehint your service/controller argument with FilesystemOperator and use the camelCase version of your storage name as the variable name. However, this practice is discouraged and won't work in future Symfony versions:

use League\Flysystem\FilesystemOperator;

class MyService
{
    private FilesystemOperator $storage;

    // The variable name $defaultStorage matters: it needs to be the
    // camelCase version of the name of your storage (foo.bar.baz -> fooBarBaz)
    public function __construct(FilesystemOperator $defaultStorage)
    {
        $this->storage = $defaultStorage;
    }

    // ...
}

2) Using manual service registration: in your services, inject the service that this bundle creates for each of your storages following the pattern 'flysystem.adapter.'.$storageName:

# config/services.yaml
services:
    # ...

    App\MyService:
        arguments:
            $storage: @flysystem.adapter.default.storage

Once you have a FilesystemOperator, you can call methods from the Filesystem API to interact with your storage.

If you need to transfer files between the local filesystem and one of your configured storages, the bundle also provides two console commands:

bin/console flysystem:push <storage> <local-source> [remote-destination]
bin/console flysystem:pull <storage> <remote-source> [local-destination]

The <storage> argument is the configured Flysystem storage name (for example default.storage), not the adapter type. When the destination is omitted, the basename of the source path is used.

Security Issues

Backward Compatibility promise

This library follows the same Backward Compatibility promise as the Symfony framework: https://symfony.com/doc/current/contributing/code/bc.html

Note: many classes in this bundle are either marked @final or @internal. @internal classes are excluded from any Backward Compatibility promise (you should not use them in your code) whereas @final classes can be used but should not be extended (use composition instead).
