- What is tattali/presigned-url used for in Laravel?
- It generates temporary, tamper-proof URLs for private files in Laravel applications. You can create and validate time-limited signed links for secure downloads, uploads, and sharing storage assets without exposing credentials. It applies an S3-style presigned URL pattern to any configured storage backend.
- How do I install tattali/presigned-url in a Laravel app?
- Install it with Composer using composer require tattali/presigned-url. Laravel package auto-discovery should register the service provider automatically. Then configure your storage disks and signing settings as described in the package README, and generate your first signed URL.
- Does tattali/presigned-url work with any Laravel filesystem disk?
- The package is designed to provide S3-style presigned URLs for any storage backend. It builds on Laravel's filesystem abstraction, so you can sign links for disks your application already uses, including local and S3-compatible storage. Check the package documentation for driver-specific behavior and any disk requirements.
- How do I generate a temporary signed URL for a private file?
- Create a signed URL through the package's API for the target disk and file path, specifying an expiry duration. The resulting URL contains a signature and expiration that authorize temporary access. Share the URL only with the intended user and keep expiry windows as short as practical.
- How does the package validate presigned URLs?
- The package provides validation for time-limited signed links by checking the signature and expiration. You can use its validation helper or route protection so invalid, tampered, or expired URLs are rejected. Keep the signing secret private and avoid logging full signed URLs.
- Can I use presigned URLs for uploads as well as downloads?
- Yes, the package is described for secure downloads, uploads, and sharing storage assets. You can create time-limited links that authorize access without exposing credentials. For uploads, ensure your disk and route support the required HTTP method and permissions.
- Which Laravel versions does tattali/presigned-url support?
- Check the package's composer.json require constraints and README for the supported Laravel versions. The package metadata and test matrix are the source of truth before adopting it in an existing application. If you use an older or newer Laravel release, run your test suite against the package first.
- How do I test presigned URL generation and validation?
- Use Laravel's testing helpers and freeze time to test expiration behavior. Generate a URL in a test, assert it validates before expiry, and assert rejection after expiry or tampering. Use Storage::fake for disk interactions where possible.
- What should I consider before using presigned URLs in production?
- Use a strong signing key, HTTPS, sensible expiry windows, and least-privilege storage credentials. Consider URL revocation, key rotation, and monitoring for repeated invalid-signature attempts. Test clock skew and caching behavior because presigned URLs act as bearer tokens.
- Are there alternatives to tattali/presigned-url for Laravel?
- Alternatives include Laravel's built-in temporaryUrl support for compatible disks, cloud provider SDKs, and custom signed-route middleware. tattali/presigned-url is useful when you want one S3-style pattern across multiple storage backends. Compare driver support, expiry controls, and maintenance activity before choosing.
