fortify-schema/dist/cjs/constants/VALIDATION_CONSTANTS.js

A modern TypeScript validation library designed around familiar interface syntax and powerful conditional validation. Experience schema validation that feels natural to TypeScript developers while unlocking advanced runtime validation capabilities.

/**
 * VALIDATION CONSTANTS
 *
 *  CENTRALIZED VALIDATION SYSTEM - SUCCESSFULLY IMPLEMENTED
 *
 * This module provides centralized configuration for all validation limits
 * across the Fortify Schema system. All validation components now use these
 * constants, making the system easy to maintain and configure.
 *
 *  ACHIEVEMENT: Replaced scattered hardcoded limits with centralized control
 *  MAINTENANCE: Change values here to update limits throughout the entire system
 *  CURRENT STATUS: System supports up to 100-level deep validation
