Robust Validator

Rule-based data validation in JS

Extendable, function-oriented, i18n-supported

Declarative ✍🏽

Declarative rule definition allows you to save your rules in different places such as configuration files, databases, etc.

Starting to validate data is very fast instead of creating complicated validation rules. You just need seconds.

Laravel-ish data validation rules are well-tested as a concept. This library is just another implementation for JavaScript.

Multi-language error messages are supported internally, unlike other libraries. It provides consistency.
