README
A simple Laravel package that lets you build streaming file transfers between two defined Laravel filesystem drivers using a factory pattern for one-line transfers. Perfect for ETL processes, data migrations, and cross-server file operations.
Requirements
- Laravel 11 or greater
- PHP 8.2 or greater
Installation
You can install the package via composer:
composer require projectsaturnstudios/laravel-x-fer
After installation, you can optionally publish the configuration file and migration:
php artisan vendor:publish --tag=xfer-config php artisan vendor:publish --tag=xfer-migrations
Run the migrations if you plan to use the logging features:
php artisan migrate
Configuration
After publishing the config file, you can modify config/file-transfers.php
to customize the batch processing behavior:
return [ /* |-------------------------------------------------------------------------- | File Transfer Batch Driver |-------------------------------------------------------------------------- | | This option controls the batch driver that will be used to process file | transfers. You may set this to any of the drivers provided by the | package or create your own custom driver that implements the | ProjectSaturnStudios\Xfer\Contracts\BatchDriver interface. | | Supported: "sync", "bus", "concurrency", "chain" | */ 'batch_processing' => [ 'driver' => env('XFER_BATCH_DRIVER', 'sync'), 'drivers' => [ 'sync' => ProjectSaturnStudios\Xfer\Drivers\BatchProcessing\SyncBatchDriver::class, 'bus' => ProjectSaturnStudios\Xfer\Drivers\BatchProcessing\BusBatchDriver::class, 'chain' => ProjectSaturnStudios\Xfer\Drivers\BatchProcessing\ChainBatchDriver::class, 'concurrency' => ProjectSaturnStudios\Xfer\Drivers\BatchProcessing\ConcurrencyBatchDriver::class, ], ], 'folder_associations' => [ 'production' => [ 'sftp' => 'production', 's3-processed' => 'production/processed', ], 'staging' => [ 'sftp' => 'staging', 's3-processed' => 'staging/processed', ], 'archive' => [ 'sftp' => 'archive', 's3-processed' => 'archive/processed', ], ], ];
Usage
One-off Transfer
Perform a simple file transfer between two storage disks:
use ProjectSaturnStudios\Xfer\Support\Facades\CopyFile; $copied = CopyFile::from('sftp', 'folder', 'doc.csv') ->to('local', 'folder', 'saved-doc.csv') ->transfer();
Transfer with Logging
Add event sourcing and audit trails to your transfers:
$results = CopyFile::from('sftp', 'folder', 'doc.csv') ->to('local', 'folder', 'saved-doc.csv') ->withLogging() ->transfer();
Transfer Multiple Files
Use batch processing for multiple file transfers:
use ProjectSaturnStudios\Xfer\Support\Facades\BatchTransfer; use ProjectSaturnStudios\Xfer\DTO\Transfers\FileObject; $batch = BatchTransfer::driver('concurrency'); foreach($transfers as $transfer) { $batch = $batch->addTransfer($transfer['source'], $transfer['destination']); } $results = $batch->dispatch();
Transfer Multiple Files with Logging
Combine batch processing with logging:
use ProjectSaturnStudios\Xfer\Support\Facades\BatchTransfer; use ProjectSaturnStudios\Xfer\DTO\Transfers\FileObject; $batch = BatchTransfer::driver('concurrency'); foreach($transfers as $transfer) { $batch = $batch->addTransfer($transfer['source'], $transfer['destination']); } $results = $batch->withLogging()->dispatch();
Batch Processing Drivers
Laravel X-Fer provides four built-in batch processing drivers:
1. Sync Driver
Processes transfers synchronously (one after another). Best for small batches or when order matters.
2. Bus Driver
Uses Laravel's job bus to queue transfers. Ideal for background processing and decoupling from the main request.
3. Chain Driver
Chains transfers using Laravel's job chaining. Useful when transfers need to happen in sequence.
4. Concurrency Driver
Processes transfers concurrently using Laravel 11's new concurrency features. Perfect for large batches where parallel processing improves performance.
Custom Drivers
You can create custom batch drivers by extending the base driver class:
use ProjectSaturnStudios\Xfer\Drivers\BatchProcessing\BatchProcessingDriver; class CustomBatchDriver extends BatchProcessingDriver { public function process(array $items, bool $use_logging = false): array|bool { // Your custom batch processing logic foreach ($items as $item) { // Process each transfer } return $results; } }
Register your custom driver in your service provider:
use ProjectSaturnStudios\Xfer\Support\Facades\BatchManager; BatchManager::extend('custom', function ($app) { return new CustomBatchDriver(); });
Alternatively, after publishing the config file, you can replace any of the built-in drivers in the batch_processing.drivers
array:
'drivers' => [ 'sync' => \App\Drivers\MyCustomSyncDriver::class, // ... other drivers ],
API Reference
CopyFile Facade
from(string $disk, string $folder, string $path): static
Define the source file location.
to(string $disk, string $folder, string $path): static
Define the destination file location.
withLogging(bool $enabled = true): static
Enable event sourcing and logging for the transfer.
transfer(): bool|TransferResult
Execute the file transfer. Returns bool
for simple transfers, TransferResult
for logged transfers.
BatchTransfer Facade
driver(?string $name = null): static

withLogging(): static
Enable logging for all transfers in the batch.
dispatch(): array|bool
Execute all transfers in the batch.
