Filament Workflows Laravel Package

Technical Evaluation

Release under review: 0.0.5 adds config-driven support for custom models and Filament resources.

• Architecture fit: Good fit for Laravel applications already using Filament admin panels and needing workflow/state-machine behavior. The new custom model/resource configuration improves domain fit by letting teams model their own workflow entities instead of relying on package defaults. However, this is still a 0.0.x package, so architecture fit should be validated through a spike rather than assumed for core business workflows.
• Integration feasibility: Likely feasible via Composer in a Laravel/Filament stack. The main integration work is publishing/adapting config, mapping custom Eloquent models to package expectations, registering custom Filament resources, and validating migrations, relationships, policies, and tenancy. Feasibility is medium: the release reduces coupling, but documentation and upgrade guarantees are likely thin at this maturity level.
• Technical risk: Pre-1.0 API instability is the primary risk. Custom model/resource config may change across releases and can affect migrations, authorization, resource discovery, and workflow persistence. The contributor is new, so maintainer bandwidth and long-term support should be assessed. Workflow transition authorization and concurrency handling must be tested explicitly.
• Key questions: Which Laravel, PHP, and Filament versions are supported? Can custom models implement required interfaces without overriding internals? Are migrations publishable and safe for existing schemas? How are transition permissions enforced? Is multi-tenancy supported? Are custom resources auto-discovered or manually registered? What is the upgrade/backward-compatibility policy? Can our domain model be tested end-to-end in a dev spike?

Integration Approach

• Stack fit: Best suited to Laravel + Filament applications where workflow administration belongs in the admin panel. The 0.0.5 custom model/resource support aligns with domain-specific entities and reduces the need to bend business models around package defaults.
• Migration path: Start with a non-production spike. Pin exactly 0.0.5, publish config and migrations, map one real workflow domain model and Filament resource, and run transition tests. If replacing an existing workflow implementation, run in parallel rather than big-bang migration.
• Compatibility: Verify Composer constraints against our Laravel, PHP, and Filament versions. Check that custom models satisfy expected traits/interfaces and that custom resources follow Filament conventions. Watch for hidden DB schema assumptions, enum/status assumptions, and policy integration points.
• Sequencing: 1) Technical spike in a dev branch; 2) define custom workflow models/resources; 3) validate authorization, tenancy, and transition concurrency; 4) add integration tests; 5) pilot one low-risk workflow; 6) pin version and establish an upgrade gate before broader rollout.

Operational Impact

• Maintenance: Early-stage package requires version pinning and active release monitoring. Custom config improves flexibility but shifts responsibility to our team for model/resource correctness. Budget for a fork/vendor contingency if upstream maintenance slows.
• Support: Expect community/GitHub support rather than vendor SLA. Assign an internal owner, document config choices, and track upstream issues. Avoid placing this on critical approval paths without a fallback plan.
• Scaling: Workflow transitions can create database writes and events; index workflow state, subject, and tenant columns. Filament resources are admin-facing, but notifications and transition side effects should be queued. Concurrency controls are needed for parallel approvals.
• Failure modes: Breaking config changes, migration conflicts, missing resource registration, authorization bypass, race conditions on transitions, and orphaned workflow records when subjects are deleted. Add idempotency, locking, and audit logging around transitions.
• Ramp-up: Low-to-medium for developers familiar with Laravel and Filament. TPM should allocate a short evaluation spike, define acceptance criteria around authorization and persistence, and start with one workflow before expanding.
