Calendar Laravel Package

Product Decisions This Supports

• Recurring Event Management: Enables building a calendar feature with recurring events (e.g., subscriptions, memberships, or scheduled tasks) without reinventing the wheel. Supports RFC 5545-compliant recurrence rules (e.g., daily, weekly, monthly, yearly events with exceptions).
• Timezone Support: Critical for global applications where events must align with user-localized time zones (e.g., SaaS platforms, international teams, or customer-facing scheduling tools).
• Reminders Integration: Optional but valuable for user engagement (e.g., notifications for appointments, deadlines, or recurring payments).
• Modular Architecture: Allows integration into existing Laravel apps without heavy refactoring, reducing technical debt for features like:
  • Scheduling Systems: For internal tools (e.g., employee shifts, project milestones).
  • Customer Portals: For booking systems (e.g., salons, fitness classes, or SaaS onboarding).
  • Internal Tools: For HR (e.g., leave calendars), finance (e.g., billing cycles), or operations (e.g., maintenance schedules).
• Build vs. Buy: Justifies outsourcing calendar logic to a specialized package (vs. building from scratch) if the team lacks expertise in recurrence rules or timezone handling.
• Roadmap Prioritization: Validates whether to invest in a full-featured calendar UI (e.g., FullCalendar) or start with backend logic first for MVP validation.

When to Consider This Package

• Look Here If:

  • Your app requires recurring events with exceptions (e.g., "Every Monday except holidays").
  • You’re using Laravel 11+ and need a lightweight, PHP-native solution (no JavaScript dependencies for backend logic).
  • Timezone handling is critical (e.g., multi-regional users).
  • You want to avoid complex dependencies (e.g., Google Calendar APIs, iCal libraries) for core functionality.
  • Your team lacks bandwidth to build recurrence logic from scratch (e.g., parsing RRULE strings, handling edge cases like daylight saving).

• Look Elsewhere If:

  • You need a frontend calendar UI (this package is backend-only; pair with FullCalendar or similar).
  • Your events are one-off (use Laravel’s built-in Carbon or database timestamps).
  • You require collaboration features (e.g., shared calendars, invites; consider Laravel Calendar or Sabre/VObject).
  • You’re on Laravel < 11 or PHP < 8.3 (compatibility risk).
  • Your use case involves complex attachments (e.g., iCal exports/imports; this package focuses on storage/recurrence).
  • You need real-time sync (e.g., WebSocket updates; this is a batch-oriented package).

How to Pitch It (Stakeholders)

For Executives/Business Leaders:

"This package lets us quickly add recurring events to our [product name]—like automated reminders for subscriptions, team schedules, or customer appointments—without building a custom system. It’s lightweight, integrates seamlessly with Laravel, and handles time zones and exceptions (e.g., skipping holidays) automatically. For example, if we’re launching a booking system, this reduces backend development time by 30% while ensuring reliability. The MIT license means no hidden costs, and the underlying library (php-rrule) is battle-tested for recurrence rules. We’d start with this for the backend, then layer on a frontend calendar UI later if needed."

For Engineering Teams:

*"This is a minimalist, dependency-efficient way to handle recurring events in Laravel 11+. Key benefits:

• Recurrence Rules: Uses php-rrule (RFC 5545 compliant) to manage complex patterns (daily/weekly/yearly + exceptions).
• Timezone Support: Events respect user-localized time zones out of the box (critical for global apps).
• Zero Frontend Lock-in: Backend-only, so we can pair it with any frontend (e.g., FullCalendar, custom Vue/React).
• Quick Setup: 3 steps—composer install, publish config, add a trait to your User model. Migrations included.
• Extensible: We can customize reminders, add validation, or integrate with notification systems (e.g., Laravel Echo).

Trade-offs: No built-in UI or real-time features, but that’s intentional—we’re focusing on core logic first. If we hit limits (e.g., need iCal exports), we can swap in Sabre/VObject later."*

For Product Managers:

*"This package aligns with our [roadmap item X] by providing a scalable, low-maintenance way to handle recurring events. For instance:

• Use Case 1: If we’re adding a ‘membership renewal’ calendar for users, this handles the backend logic for automated reminders (e.g., ‘Renew in 7 days’).
• Use Case 2: For internal tools (e.g., ‘Employee Leave Calendar’), it reduces dev time to build recurrence rules for shifts or PTO.
• Risk Mitigation: Since it’s MIT-licensed and open-source, we’re not locked into a vendor. The package’s simplicity means we can audit or extend it easily.

Next Steps:

1. Validate if our primary use case fits (recurring + timezone-sensitive events).
2. Benchmark against alternatives (e.g., building custom logic vs. this package).
3. If adopted, prioritize frontend integration (e.g., FullCalendar) in a later sprint."*
