Yii filesystem

An abstract filesystem that allows to swap underlying file system without rewriting application code. Based on Flysystem.

Requirements

The package requires PHP 8.0 and is meant to be used with Yii3.

Installation

composer require yiisoft/yii-filesystem

After installation, the Yiisoft\Yii\Filesystem\FilesystemInterface will be automatically registered in the main application container. This interface provides a local filesystem with root, as defined in the @root alias of the aliases parameter.

Getting started

The service could be obtained via DI container autowiring:

public function view(\Yiisoft\Yii\Filesystem\FilesystemInterface $filesystem)
{
    $someFileContent = $filesystem->read('/runtime/somefile.txt');
    //...
}

Also you can use aliases

$someFileContent = $filesystem->write('@views/site/testfile.txt', 'Test content');

Configuration

Additional filesystems could be configured in config/params.php as described below:

'file.storage' => [
    'runtimeStorage' => [
        'adapter' => [
            'class' => \League\Flysystem\Local\LocalFilesystemAdapter::class,
            '__construct()' => [
                dirname(__DIR__) . '/runtime',
                \League\Flysystem\UnixVisibility\PortableVisibilityConverter::fromArray([
                    'file' => [
                        'public' => 0644,
                        'private' => 0600,
                    ],
                    'dir' => [
                        'public' => 0755,
                        'private' => 0700,
                    ],
                ]),
                LOCK_EX,
                \League\Flysystem\Local\LocalFilesystemAdapter::DISALLOW_LINKS
            ]
        ],
        'aliases' => [
            '@cache' => '@root/cache',
        ]
    ],
    'documentStorage' => [
        'adapter' => [
            'class' => \League\Flysystem\Local\LocalFilesystemAdapter::class,
            '__construct()' => [
                dirname(__DIR__) . '/docs',
                \League\Flysystem\UnixVisibility\PortableVisibilityConverter::fromArray([
                    'file' => [
                        'public' => 0644,
                        'private' => 0600,
                        ],
                    'dir' => [
                        'public' => 0755,
                        'private' => 0700,
                        ],
                    ]),
                    LOCK_EX,
                    \League\Flysystem\Local\LocalFilesystemAdapter::DISALLOW_LINKS
                ]
        ],
        'aliases' => [
             '@invoices' => '@root/export/invoices',
             '@orders' => '@root/export/orders',
        ],
    ],
],

Aliases runtimeStorage and documentStorage will be automatically registered in the main application container. So, you can get it from the container:

public function index(ContainerInterface $container) 
{
    $documentStorage = $container->get('documentStorage');
}

If you prefer to use autowiring, you can create own interface for your filesystem.

interface ImageStorageInterface extends \Yiisoft\Yii\Filesystem\FilesystemInterface
{
}

And then register it in the params:

'file.storage' => [
    ImageStorageInterface::class => [
        'adapter' => [
            'class' => \League\Flysystem\Local\LocalFilesystemAdapter::class,
            '__construct()' => [
                dirname(__DIR__) . '/storage/images',
                \League\Flysystem\UnixVisibility\PortableVisibilityConverter::fromArray([
                    'file' => [
                        'public' => 0644,
                        'private' => 0600,
                    ],
                    'dir' => [
                        'public' => 0755,
                        'private' => 0700,
                    ],
                ]),
                LOCK_EX,
                \League\Flysystem\Local\LocalFilesystemAdapter::DISALLOW_LINKS
            ]
        ],
    ],
]

Now you can use it like this:

//controller action
public function addImage(ImageStorageInterface $imageStorage)
{
    //get image stream...

    $imageStorage->writeStream('/path/to/image/myimage.jpeg', $myImageStream);
}

You can find documentation on FilesystemInterface methods in the Flysystem Docs.
