Validations

🖍️ 🛡 🚀

Validations done right.

Platform-agnostic validation library for JavaScript applications with extra focus on composable validations and message translations. Includes (pretty much) out-of-the-box support for both Redux Form and React Intl.

Create your validation schema based on priciples of functional programming.
