Product Decisions This Supports

Enables enterprise-grade validation for API payloads and configuration files, ensuring data integrity and reducing runtime errors
Supports all major JSON Schema drafts (2020-12 to draft-06), providing future-proof compatibility for evolving standards
Custom error handling ($error keyword) and filters ($filters) allow business-specific validation logic without modifying core schemas
Eliminates need for custom validation implementation (build vs. buy), reducing maintenance burden and accelerating time-to-market
Critical for use cases like payment processing, user data input validation, and microservice communication where schema compliance is non-negotiable

When to Consider This Package

Adopt when your PHP application requires robust, standards-compliant JSON validation with advanced features (e.g., $data keyword, URI templates)
Ideal for projects needing customizable error messages, schema reuse via $map, or strict validation of complex nested structures
Avoid if: your stack is non-PHP, validation needs are trivial (e.g., simple type checks), or you prefer a schema-less approach like TypeScript runtime checks
Not suitable for non-JSON data formats or when strict JSON Schema compliance is unnecessary (e.g., internal tools with simple data shapes)

Executives: "This package ensures data quality across customer-facing systems, preventing costly errors in critical workflows like payments and user onboarding. By leveraging a mature, open-source solution, we avoid building and maintaining custom validation logic, saving engineering resources while reducing risk."
Engineering: "It's a lightweight, dependency-light integration (only PHP 7.4+ and standard extensions) with comprehensive features like custom error handling and schema composition. Active maintenance and Apache 2.0 license make it safe for production use, with clear documentation for quick adoption."
