Sentinel Laravel Package

Getting Started

Start by confirming how your app’s registration flow handles an existing email address. In v2.4.1, the important behavior is: if someone tries to register with an email that already belongs to an unactivated account, the package can resend the activation email instead of only returning a duplicate-account error.

Minimal steps:

1. Update the package to v2.4.1.
2. Review your registration controller/request/service and confirm it distinguishes between:
   • brand-new email,
   • existing activated account,
   • existing unactivated account.
3. Check the package’s activation notification/service API and use that path for resend rather than duplicating token/email logic.
4. Add a feature test for the “register with existing unactivated email” case.
5. Confirm mail configuration and queue workers are running if activation emails are queued.

First use case: a user registered but never clicked the activation link, then tries to register again. Your app should resend the activation email and return a safe, generic response such as “If this email needs activation, we’ve sent a new link.”

Implementation Patterns

Use the package as the activation-email boundary in your registration flow. A typical pattern:

public function register(RegisterRequest $request)
{
    $user = User::where('email', $request->email)->first();

    if ($user && ! $user->isActivated()) {
        // Prefer the package's resend API/service if available.
        $this->activationService->resend($user);

        return back()->with(
            'status',
            'If this email needs activation, we have sent a new activation link.'
        );
    }

    if ($user) {
        return back()->withErrors([
            'email' => 'This email is already registered.',
        ]);
    }

    // Normal registration + activation email.
}

Practical patterns:

• Keep resend logic in a small service or action class, not directly in the controller.
• Regenerate or refresh activation tokens according to the package’s expectations; avoid leaving multiple valid tokens unless the package supports that intentionally.
• Queue activation emails in production and ensure your queue is monitored.
• Throttle resends by email/IP to reduce abuse.
• Use generic response messages to avoid exposing whether an account exists.
• Add tests for:
  • new registration sends activation email,
  • duplicate unactivated registration resends activation email,
  • duplicate activated registration does not resend activation email,
  • invalid/throttled resend requests behave safely.

Integration tip: if the package emits events or exposes a notification class, hook localization, branding, and mail transport changes there rather than overriding the registration flow.

Gotchas and Tips

• Account enumeration: returning “activation resent” only when an unactivated account exists can leak account state. Prefer neutral messaging.
• Activated vs. unactivated: make the distinction explicit in your user model or package integration. Do not resend activation emails to already activated users.
• Token lifecycle: verify whether resending invalidates prior activation links. If not, consider whether multiple valid links are acceptable.
• Case sensitivity: normalize emails consistently; “[email protected]” and “[email protected]” should resolve to the same account in most Laravel apps.
• Soft-deleted users: decide whether a soft-deleted account can receive an activation resend. Usually it should not.
• Rate limiting: activation resend is a common abuse target. Apply throttling and consider logging repeated attempts.
• Mail failures: resend may succeed at the package level but fail at transport level. Handle/log notification failures and avoid promising delivery.
• Queues: if activation notifications are queued, tests using Mail::fake() or Notification::fake() should assert the notification was sent, not just that a response was returned.
• Config quirks: check the package config for token expiry, notification class, route names, and model/guard assumptions after updating.
• Extension points: customize the activation notification, token generation, and resend throttling via package config or overridden classes rather than forking the registration flow.
• Release scope: v2.4.1 appears to be a focused, non-breaking feature release. Still run your existing activation/registration tests after updating, especially if you had custom duplicate-registration handling.
