Module schema

Validate whole form objects with typed, field-by-field rules.

Import from lanka-validations/schema, or from the package root.

Combine the built-in rules with your own. Rules run in order and stop at the first failure for each field; the parsed output type is inferred.

Example

import { createSchemaValidator, rules } from 'lanka-validations/schema';

const signUp = createSchemaValidator({
  nic: rules.nic(),
  phone: rules.optional(rules.mobile()),
});

const result = signUp.validate({ nic: '921234567V' });
if (result.isValid) result.data.nic.dobString; // '1992-05-02'
