SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Ensures data integrity and security by validating all user input across client and server layers, preventing malformed data and common attack vectors.

Core Features & Use Cases

Centralized validation rules covering type checks, format validation, range constraints, and business rules to enforce consistent data quality.
Real-time and API-level feedback with clear, actionable error messages to improve user experience and developer efficiency.
Input sanitization and allowlist-based validation to mitigate injection risks and satisfy security and compliance requirements.

Quick Start

Integrate a centralized validation layer and begin validating inputs in forms, APIs, and data-processing pipelines.

FAQPage Schema

How do I validate user input on both client and server sides?▼

To validate user input consistently across client and server, use a centralized validation specification that enforces type, format, range, and business rules. This ensures consistent data quality and prevents malformed data from entering your system.

What is the best way to prevent injection attacks through data validation?▼

The best way to prevent injection attacks through data validation is implementing input sanitization and allowlist-based validation across your endpoints. This mitigates injection risks by strictly controlling accepted data formats and rejecting malformed input.

How do I implement centralized validation rules for API endpoints and forms?▼

Implement centralized validation rules by defining a core specification for type checks, format validation, range constraints, and business rules. Apply this specification across real-time client-side forms and server-side API endpoints to enforce consistent data quality.

How should error handling work for failed input validation on APIs?▼

Error handling for failed input validation on APIs should return clear, actionable error messages in real-time. Using a centralized validation layer ensures comprehensive error handling that improves user experience and developer efficiency.

Does centralized input validation work for data-processing pipelines?▼

Yes, centralized input validation works for data-processing pipelines. You integrate the validation layer to check inputs in pipelines, ensuring data integrity and satisfying security and compliance requirements before processing occurs.

Why do I need server-side validation if I already have client-side form checks?▼

You need server-side validation alongside client-side form checks because client checks can be bypassed. Enforcing rigorous server-side endpoints protects data integrity and security against malformed data and common attack vectors directly at the source.
