Laravel Sharelink Laravel Package

Getting Started

Install the package via Composer, publish migrations and config, then run migrations:

composer require grazulex/laravel-sharelink
php artisan vendor:publish --tag="sharelink-migrations"
php artisan vendor:publish --tag="sharelink-config"
php artisan migrate

The first use case is generating a temporary link to share a private file. For example, to share a document with a 30-minute expiration and 3 max clicks:

use Grazulex\ShareLink\Facades\ShareLink;

$link = ShareLink::create('storage/app/private/contract.pdf')
    ->expiresIn(30)
    ->maxClicks(3)
    ->generate();

// Send $link->url via email or embed in UI

Check config/sharelink.php to verify the default route prefix (/share) and middleware — you’ll need to route incoming share links, which the package handles automatically via its built-in controller.

Implementation Patterns

• File Sharing with Laravel Storage: Use disk-agnostic paths ('s3://bucket/report.pdf' or 'public://invoices/...') — the package respects Laravel’s filesystem abstraction and supports X-Sendfile/X-Accel-Redirect for optimized delivery in production.

• Route-Based Sharing: Protect sensitive routes without exposing IDs:

  ShareLink::create([
      'type' => 'route',
      'route' => 'admin.audit.show',
      'parameters' => ['id' => 456]
  ])->expiresIn(60)->generate();
  

• Model Previews: Enable secure preview of model data without direct access:

  $link = ShareLink::create([
      'type' => 'model',
      'class' => User::class,
      'id' => $user->id
  ])->expiresIn(45)->generate();
  

  The model’s toArray() output is serialized and served as JSON upon access.

• High-Security Scenarios: Combine password, IP filtering, burn-after-reading, and metadata:

  ShareLink::create($sensitivePdf)
      ->burnAfterReading()
      ->withPassword('SecurePass!2025')
      ->metadata(['allowed_ips' => ['10.0.0.0/8']])
      ->maxClicks(1)
      ->generate();
  

• CLI & Automation: Use Artisan commands to manage links programmatically:

  php artisan sharelink:revoke abc123
  php artisan sharelink:prune --days=7
  

• Observability: Hook into events like ShareLinkAccessed, ShareLinkExpired, or ShareLinkRevoked via event listeners to integrate with logging, analytics, or alerting tools (e.g., Slack, Sentry).

Gotchas and Tips

• Signed URLs are Optional: The ShareLink::signedUrl() method adds a second layer of Laravel signature validation — useful for high-stakes links but not enabled by default. Ensure your frontend doesn’t expect signed URLs unless configured via config/sharelink.php.

• Burn-After-Reading ≠ First Request: Burning occurs only after successful access (i.e., correct password if required). Failed attempts (e.g., wrong password) do not consume the burn — verify in tests with dd($link->clicks).

• Rate Limiting is Per-Link: Password throttling and general rate limiting apply per share link, not globally. Avoid reusing passwords across many active links — this could trigger local lockouts.

• X-Sendfile Requires Server Config: To serve large files efficiently, enable x_accel_redirect or x_sendfile in both config/sharelink.php and your web server (nginx/Apache) — otherwise, the file will stream via PHP (risking memory/timeouts).

• Token Safety: Tokens are UUID-based but must be treated as secrets. Never log raw tokens, and use ShareLink::uuid($token) or ShareLink::find($id) for lookups — avoid parsing URLs manually.

• Metadata Column: The metadata JSON column supports custom business data (e.g., campaign ID, anonymized IP hash), but avoid storing raw PII unless encrypted at rest. Remember: it’s indexed via JSON path queries (MySQL 5.7+ / PostgreSQL) if needed later.

• Testing Tip: In tests, use ShareLink::fake() to bypass DB writes and assert behaviors like URL generation or expiration logic without side effects. Combine with ->withPassword(...) and ->burstAfterReading() to verify security flows.
