Validation Laravel Package

Product Decisions This Supports

• Feature Expansion: Accelerates development of financial, publishing, and technical validation use cases (e.g., IBAN/BIC for banking, ISBN for media, credit card payments, or hex color codes for design tools).
• Roadmap Efficiency: Reduces custom validation development time by 37 pre-built rules, enabling faster iteration on compliance-heavy features (e.g., GDPR data formats, e-commerce payments).
• Build vs. Buy: Buy for niche validations (e.g., ISO 8601 dates, UUIDs, or locale-specific formats) where off-the-shelf Laravel rules fall short. Avoid reinventing wheel for edge cases like BIC/SWIFT codes or IATA airport codes.
• Use Cases:
  • FinTech: Validate bank transfers, payment gateways.
  • Media/Publishing: ISBN, ISSN, or DOI validation for content platforms.
  • E-commerce: Credit card, VAT numbers, or product SKUs.
  • Design Tools: Hex colors, RGB values, or font weights.
  • Compliance: ISO standards (e.g., ISO 3166 country codes).

When to Consider This Package

• Adopt if:
  • Your app requires domain-specific validations beyond Laravel’s core (e.g., financial, ISBN, or technical formats).
  • You’re building multi-language support for error messages (package includes translations).
  • Your team lacks bandwidth to maintain custom validation logic (e.g., regex for BIC codes).
  • You’re using Laravel 10+ and want zero-config integration (auto-discovery).
• Look elsewhere if:
  • You need real-time validation (e.g., API rate limits) → Use Laravel’s built-in rules or a dedicated service.
  • Your use case is highly dynamic (e.g., user-defined formats) → Custom validation may be better.
  • You’re on Laravel <10 → Check compatibility or fork.
  • You require enterprise-grade support (package is MIT-licensed, community-driven).

How to Pitch It (Stakeholders)

For Executives: "This package cuts validation development time by 80% for critical use cases like payments, media, or compliance. For example, adding IBAN/BIC validation for our European banking feature would take days to build manually—but with this, it’s a one-liner. It’s a low-risk, high-reward way to accelerate feature delivery without hiring specialized devs."

For Engineering: *"Intervention Validation plugs into Laravel’s existing Validator facade, so no architecture changes. It adds 37 rules (e.g., creditcard, hexadecimalcolor, isbn) with multi-language error messages—perfect for:

• FinTech: bic, iban, creditcard rules.
• Media: isbn, issn, doi for content platforms.
• Design: hexcolor, rgb for tools. Zero config, MIT-licensed, and actively maintained. Let’s prototype with it before building custom logic."*
