Filament Calendar Laravel Package

Technical Evaluation

• Architecture fit: The package is a Filament v5 form component/plugin for Jalali and Gregorian calendar selection. It fits Laravel applications that already use Filament for admin or internal tooling and need Persian/Farsi date entry alongside Gregorian storage. It is not a general Laravel date library and adds little value outside Filament-based UIs.
• Integration feasibility: Likely installable via Composer with service-provider/plugin registration, asset publishing, and a Filament form field. Feasible for a team already comfortable with Filament, Livewire, Alpine.js, and Tailwind. Initial-release documentation and upgrade guidance are the main unknowns.
• Technical risk: Medium. v1.0.0 and a Filament v5 target create maturity and compatibility risk. Date conversion is business-critical: Jalali leap years, month lengths, timezone/DST boundaries, validation, and persistence must be verified. UI risks include RTL layout, accessibility, asset publishing, and breakage on Filament upgrades.
• Key questions: Which exact Laravel, PHP, Filament, Livewire, and Alpine versions are supported? Is this a plugin or a standalone form field? Are dates persisted as Gregorian ISO values or Jalali strings? How are timezones and DST handled? What validation rules ship with the field? Does it support date-time, ranges, and clearing? Is the license compatible? Is there a test suite and maintenance commitment? How are assets built and versioned? Does it support RTL and accessibility requirements? What is the upgrade policy for Filament v5 minor releases?

Integration Approach

• Stack fit: Best fit is Laravel + Filament v5 admin panels with PHP 8.x, Livewire, Alpine.js, and Tailwind. Confirm production stack versions before adoption. For non-Filament UIs or API-only services, evaluate the underlying conversion logic separately rather than adopting the package wholesale.
• Migration path: Prefer storing dates in Gregorian format in the database and using the package only for input/display. Replace native Filament date pickers incrementally where Persian calendar entry is required. If existing systems store Jalali strings, plan a data migration and dual-format validation before rollout.
• Compatibility: Pin package and Filament versions in Composer. Test against the exact production Laravel/PHP/Livewire versions. Verify published assets, cache busting, RTL behavior, and form validation on submit. Confirm that Filament v5 is a stable target for the team’s release cadence.
• Sequencing: Run a sandbox spike first. Validate conversion against known edge dates, including Jalali leap years, month boundaries, and DST transitions. Add automated tests for form submission and persisted DB values. Pilot in one low-risk Filament resource, document usage patterns, then roll out to broader admin forms. Avoid scheduling, billing, or compliance-critical dates until the pilot proves correctness.

Operational Impact

• Maintenance: v1.0.0 requires active ownership. Track upstream Filament changes, Laravel/PHP security updates, and package issue activity. Date logic is sensitive enough that an unmaintained dependency may require forking or replacing. Keep the integration surface small.
• Support: Community support for an initial release is likely limited. Assign an internal owner and document fallback behavior to the native Gregorian picker. Confirm maintainer responsiveness and license terms before production use.
• Scaling: Likely low server impact because calendar rendering is client-side. Watch admin asset size and caching rather than CPU. If conversion is server-side, load is still negligible for typical admin traffic. Scaling risk is mainly operational correctness, not throughput.
• Failure modes: Incorrect dates persisted due to timezone or conversion bugs; invalid Jalali dates accepted by validation; UI breakage after Filament or Livewire upgrades; missing published assets; RTL layout defects; DST/leap-year edge cases; package abandonment. Mitigate with automated date-conversion tests, staging verification, feature flags, and monitoring of form submission errors.
• Ramp-up: Developers need basic Jalali calendar awareness plus Filament form-field conventions. QA and admin users need clear calendar-toggle and format guidance. Expect a few days for technical spike and a short pilot; broader rollout depends on the number of Filament forms and the criticality of date fields.
