README

A SOLID file upload layer with support for AWS S3, LocalStack and local filesystem.

🤔 Why?

Uploading files across different environments often requires switching between storage backends. This library provides a clean, testable abstraction over multiple drivers using SOLID principles, making your code easier to maintain and extend.

🚀 Features

• Upload to Amazon S3, LocalStack, or local filesystem
• List buckets and files
• Create buckets (repositories)
• Interface-driven architecture (SOLID principles)
• Compatible with PHPUnit for automated testing
• Easily extendable with custom drivers

📦 Installation via Composer

Local

"repositories": [
  {
    "type": "path",
    "url": "../upload-abstraction-php"
  }
],
"require": {
  "yourvendor/upload-abstraction": "*"
}

Packagist

composer require chrisdjst/upload-abstraction

✅ Usage Example

use UploadAbstraction\UploaderFile;
use UploadAbstraction\Enums\UploaderDriver;

$upload = new UploaderFile(UploaderDriver::S3);
$upload->createRepository('my-bucket');
$upload->upload('my-bucket', 'file.txt', '/tmp/file.txt');
$files = $upload->listObjects('my-bucket');

⚙️ Configuration (Optional)

Create a .env file if needed:

UPLOAD_DRIVER=s3
AWS_REGION=us-east-1
AWS_ENDPOINT=http://localstack:4566
AWS_ACCESS_KEY_ID=test
AWS_SECRET_ACCESS_KEY=test

🧪 Running Tests

composer install
vendor/bin/phpunit

Generate code coverage:

vendor/bin/phpunit --coverage-html coverage/

🐳 LocalStack Support (Docker)

version: "3.8"
services:
    localstack:
        image: localstack/localstack
        ports:
            - "4566:4566"
        environment:
            - SERVICES=s3
            - AWS_DEFAULT_REGION=us-east-1

📚 Extendable Architecture

You can add custom storage drivers by implementing the UploadAbstraction\Contracts\UploaderDriverInterface interface. This allows seamless integration with other providers (e.g. Google Cloud Storage, Azure Blob Storage).
