Use when declaring, customizing, composing, or conditionally applying validation rules in a Regle form. For form setup see regle.

Regle Rules

Validation rules for Regle. Rules come from @regle/rules, but you can also write your own with createRule, customize them with wrappers, and combine them with operators.

import { useRegle } from '@regle/core';
import { required, email, minLength } from '@regle/rules';

const { r$ } = useRegle(
  { email: '' },
  { email: { required, email, minLength: minLength(5) } }
);

Key Concepts

• All rules are optional by default; add required to enforce a field.
• Built-in rules are imported from @regle/rules; some are factories that take parameters (e.g. minLength(3)).
• Custom rules use createRule for reusability, or an inline function for one-offs.
• Wrappers adapt an existing rule (message, params, async, tooltip) without rewriting it.
• Operators combine or conditionally apply rules.
