Validation Laravel Package

Product Decisions This Supports

• Brazilian-market localization for forms and onboarding. resultsystems/validation extends Laravel's validator with locale-specific rules (e.g., CPF/CNPJ document numbers, CEP postal codes, and regional phone formats) that are not shipped in core Laravel. This directly unblocks signup, KYC, checkout, and address-entry flows for any product launching or expanding in Brazil.
• Build-vs-buy for validation rules. Instead of writing and maintaining custom Rule classes and Portuguese error messages in-house, teams can adopt this package to shorten time-to-market for a regional release. Useful input to a roadmap decision: spend engineering sprints on a commodity concern, or buy it off the shelf under MIT.
• Roadmap signal for internationalization. If the product roadmap includes LATAM expansion, this package represents the kind of thin, low-cost dependency that lets you ship localized validation without a dedicated i18n epic.
• Use-case fit: lead-gen and registration forms, e-commerce checkout with Brazilian billing/shipping, government or fintech compliance flows that require document-number checks, and any CRUD app where user-entered identifiers need format and checksum validation.
• Risk decision: at 28 stars and a low maintenance score (0.38), adoption is a low-ceremony, higher-ownership decision—fine for internal tools or a bounded regional feature, riskier as a load-bearing dependency in a regulated core system.

When to Consider This Package

Adopt when:

• You are shipping to a Brazilian (or broader LATAM) audience and need CPF/CNPJ, CEP, or localized phone validation quickly.
• You are on Laravel 5.x–12.x and want compatibility across a version range rather than a single-version lock-in.
• The requirement is a bounded, well-understood domain (document/format validation) where the rules are stable and the blast radius of replacing the library is small.
• Your team is comfortable vendoring or forking an MIT package—it is small and easy to own if upstream goes quiet.
• You want to avoid bikeshedding over checksum algorithms and error-message wording that this package already encodes.

Look elsewhere or build in-house when:

• You need enterprise-grade maintenance guarantees (SLAs, active CVE response, frequent releases). Low star count and low activity suggest a single-maintainer risk profile.
• Validation is compliance-critical (regulated KYC/AML) and must be independently audited—then own the rules and their tests explicitly.
• You are not targeting Brazil/LATAM; core Laravel validation plus a mature, widely adopted rules library is a better default.
• You are on a non-Laravel stack or a heavily customized validation pipeline where the integration cost outweighs the benefit.

How to Pitch It (Stakeholders)

For executives (one paragraph): This is a small, free, open-source add-on for our Laravel backend that lets us validate Brazilian-specific data—like CPF/CNPJ tax IDs, postal codes, and phone numbers—out of the box. It removes a chunk of custom development from any Brazil-facing feature, accelerating launch while cutting engineering cost. It's MIT-licensed and low-risk in scope, though it is maintained by a small community, so we'd treat it as a dependency we're prepared to fork and own rather than a long-term vendor commitment.

For engineering leads (bullets):

• What it does: Adds locale-specific validation rules and messages on top of Laravel's validator; compatible with Laravel 5.x through 12.x.
• Why use it: Avoids reinventing checksum logic and localized error messaging; small, readable surface area that we can fork under MIT if needed.
• Cost/effort: Near-zero integration effort—a Composer dependency plus rule usage in Form Requests.
• Risk posture: Low popularity (~28 stars), single-maintainer signal. Mitigate by pinning the version, adding our own tests around the rules we rely on, and keeping a fork path open.
• Recommendation: Approve for regional features and internal tools now; revisit if it becomes load-bearing in regulated workflows.
