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.

Open Validarium in a RunKit sandbox!

See our documentation site.

import { validate, isRequired, isEmail, hasLengthMax, hasValueMin } from 'validarium';

const validateUserForm = validate({
	email: [isRequired, isEmail, hasLengthMax(200)],
	age: [isRequired, isNumber, hasValueMin(18)],
});

validateUserForm({ email: 'something', age: 16 });
// Returns { email: EmailMessage, age: NumberMessage }
//
// EmailMessage is { id: 'validarium.isEmail', defaultMessage: 'Not a valid email format' }
// NumberMessage is { id: 'validarium.isNumber', defaultMessage: 'Not a number' }

Every validation is optional and null-safe. If you want to test against null, please use the isRequired validation.

Of course, validating field arrays, combining multiple validation schemas, and overriding validation messages with custom ones is supported as well.

Installation

Use either of these commands based on the package manager you prefer.

yarn add validarium

npm i validarium

CDN

It is possible to use validarium to start quickly prototype directly in browser.

We provide two Universal Module Definition (UMD) bundles:

• development version: https://unpkg.com/validarium@latest/dist/validarium.js
• production version: https://unpkg.com/validarium@latest/dist/validarium.min.js

⚠️ Using this approach in production is discouraged though - the client has to download the entire library, regardless of which functions are actually used, affecting performance and bandwidth utilization.
