SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Inadequate or inconsistent data validation leads to security vulnerabilities (e.g., injection attacks), data corruption, and a frustrating user experience due to unclear error feedback.

Core Features & Use Cases

  • Server-Side Enforcement: Always implement server-side validation for security and data integrity, never trusting client-side checks alone.
  • Client-Side Feedback: Provide immediate user feedback with client-side validation to improve user experience by catching errors before submission.
  • Fail-Fast & Specific Errors: Validate input as early as possible and reject invalid data with clear, field-specific error messages (e.g., "Email must be a valid address").

Quick Start

Implement comprehensive validation for a user registration form, including server-side email format checks, client-side password strength feedback, and specific error messages for invalid input.
