tv4
A lightweight JavaScript library for validating data against JSON Schema Draft v4.
What is tv4?
Tiny Validator (tv4) is a JavaScript library that validates data against JSON Schema Draft v4. It checks if JSON objects conform to specified schemas, ensuring correct data types, structures, and constraints. It solves the problem of programmatically verifying data integrity in applications and APIs.
JavaScript developers building applications or APIs that require robust data validation, especially those working with JSON data and needing compliance with JSON Schema standards.
Developers choose tv4 for its small footprint, full Draft v4 support, and extensibility through custom validators. It works consistently across browsers and Node.js without dependencies, making it a reliable, lightweight alternative to heavier validation libraries.
