shared/validation/validatorUtils

Shared validation utilities using the validator package.

Remarks

This module provides validation functions that can be used by both frontend and backend to ensure consistent validation behavior. Uses the well-tested validator.js package for reliable validation.

The functions in this module replace manual validation patterns throughout the codebase, providing consistent validation behavior and better security.

Example

// Replace manual string validation
// Old: typeof value === "string" && value.trim().length > 0
// New: isNonEmptyString(value)

// Replace manual URL validation
// Old: /^https?:///.test(url)
// New: isValidUrl(url)

// Replace manual array validation
// Old: Array.isArray(arr) && arr.every(item => typeof item === "string")
// New: isValidIdentifierArray(arr)
