Ohdear Php Sdk Laravel Package

Technical Evaluation

Architecture Fit

• Microservices/API-First Fit: The SDK is ideal for Laravel/PHP applications requiring Oh Dear API integration (e.g., uptime monitoring, status pages, or incident management). It abstracts HTTP logic via Saloon, a robust HTTP client library, making it a clean fit for API-driven workflows (e.g., cron jobs, CLI tools, or background tasks).
• Domain-Specific Abstraction: The SDK encapsulates Oh Dear’s monitors, checks, status pages, and maintenance windows into DTOs (Data Transfer Objects) and enums, reducing boilerplate for common operations (e.g., CheckResult::isDown()).
• Event-Driven Potential: While the SDK itself is synchronous, it could be extended to emit events (e.g., via Laravel’s events system) when monitor states change (e.g., MonitorDown, CertificateExpiring), enabling reactive workflows.

Integration Feasibility

• Laravel Compatibility:
  • Service Provider: The SDK can be bootstrapped as a Laravel service provider to bind the OhDear client to the container, enabling dependency injection.
  • Facade Pattern: A facade (e.g., OhDear::monitors()) could simplify usage in Blade templates or controllers.
  • Queue Jobs: Async operations (e.g., requestCheckRun()) can be wrapped in Laravel queues to avoid blocking requests.
• Database Sync: The SDK’s DTOs can be serialized to JSON or mapped to Eloquent models for local caching (e.g., storing monitor states in a monitors table).
• Testing: Saloon’s built-in mocking and test helpers align well with Laravel’s testing tools (e.g., Http::fake()).

Technical Risk

Key Questions

1. Use Case Priority:
   • Will the SDK be used for real-time monitoring (e.g., dashboard updates) or batch processing (e.g., nightly reports)?
   • Are status pages or maintenance windows the primary focus, or both?
2. Data Flow:
   • Should monitor data be synced locally (e.g., for offline analysis) or treated as read-only API data?
   • Will the app trigger actions based on Oh Dear’s data (e.g., Slack alerts, auto-scaling)?
3. Authentication:
   • Will multiple API tokens be used (e.g., per team)? If so, how will they be managed?
4. Extensibility:
   • Are there plans to extend the SDK (e.g., add custom checks or webhook listeners)?
   • Should the SDK be wrapped in a Laravel package for internal reuse?
5. Compliance:
   • Does Oh Dear’s API usage align with data residency or GDPR requirements?

Integration Approach

Stack Fit

• Laravel Core:
  • Service Container: Register the SDK as a singleton binding:

    $this->app->singleton(OhDear::class, function ($app) {
        return new OhDear(config('services.ohdear.token'));
    });
    

  • Config: Store API token and timeout in config/services/ohdear.php:

    'token' => env('OHDEAR_API_TOKEN'),
    'timeout' => env('OHDEAR_TIMEOUT', 10),
    

• Queue System:
  • Wrap SDK calls in Laravel Jobs for async operations (e.g., CreateMonitorJob).
  • Example:

    OhDear::dispatchSync(new CreateMonitorJob($monitorData));
    

• Event System:
  • Publish events for monitor state changes (e.g., MonitorStatusUpdated).
  • Example listener:

    public function handle(MonitorStatusUpdated $event) {
        if ($event->monitor->isDown()) {
            Alert::send('slack', $event->monitor->url);
        }
    }
    

• Testing:
  • Use Saloon’s mocking in PHPUnit:

    Saloon::shouldReceive('get')
        ->with('monitors')
        ->andReturn(new OhDearResponse([...]));
    

Migration Path

1. Phase 1: Core Integration (2–4 weeks):
   • Set up SDK in a Laravel service provider.
   • Implement CRUD for monitors and status pages in a dedicated OhDearService.
   • Add basic error handling (log to Sentry/Monolog).
2. Phase 2: Async & Caching (1–2 weeks):
   • Move non-critical operations to queues (e.g., requestCheckRun).
   • Cache monitor data in Redis (TTL: 5 minutes).
3. Phase 3: Extensions (Ongoing):
   • Build webhook listeners for real-time updates.
   • Create custom commands (e.g., php artisan ohdear:sync-monitors).
   • Add Laravel Notifications for alerts.

Compatibility

• Laravel Versions: Tested with Laravel 10+ (PHP 8.1+). Saloon v4 requires PHP 8.0+.
• Oh Dear API: The SDK matches Oh Dear’s 2026-03-30 API version. Monitor for deprecations in future releases.
• Dependencies:
  • Guzzle HTTP (via Saloon) for HTTP requests.
  • Symfony Contracts (already in Laravel).
  • No conflicts with Laravel’s core packages.

Sequencing

Operational Impact

Maintenance

• SDK Updates:
  • Monitor Oh Dear’s changelog and Saloon’s releases for breaking changes.
  • Update dependencies via composer update ohdearapp/ohdear-php-sdk --with-dependencies.
• Token Rotation:
  • Implement a cron job to refresh tokens before expiration (Oh Dear tokens expire after 1 year).
  • Example:

    $ohDear->rotateToken(oldToken: 'abc123', newToken: 'def456');
    

• Schema Validation:
  • Use Saloon’s request validation to fail fast on API changes:

    $request = new CreateMonitorRequest(['url' => 'invalid']);
    $response = $ohDear->send($request); // Throws ValidationException
    

Support

• Debugging:
  • Enable Saloon’s debug mode for API logs:

    $ohDear = new OhDear(token: '...', debug: true);
    

  • Use Laravel’s debugbar to inspect Oh Dear responses.
• Common Issues:
  • Rate Limits: Implement retry logic with jitter.
  • Timeouts: Adjust timeoutInSeconds for slow endpoints.
  • CORS: Ensure Oh Dear’s API is whitelisted in your firewall.

Scaling

• Horizontal Scaling:
  • The SDK is stateless (except for cached data), so it scales horizontally with Laravel’s queue workers.
  • For high-volume checks, use Oh Dear’s webhooks instead of polling.
• Performance Bottlenecks:
  • Batch API Calls: Use Oh Dear’s pagination (e.g., monitors?page=2) for large datasets.
  • Parallel Requests: Saloon supports parallel requests for independent operations (e.g
