Rules (validation)

Helpers for Input rules. Each factory returns an InputRule.

API

import { rules, runRules } from 'pomikit-ui'
import type { InputRule } from 'pomikit-ui'

type InputRule = (value: string) => true | string | null | undefined | void

Helper	Behavior
rules.required(message?)	Non-empty after trim
rules.email(message?)	Empty or valid email
rules.min(length, message?)	Minimum length
rules.max(length, message?)	Maximum length
runRules(value, list)	First failing message, or undefined

Example

<script setup lang="ts">
import { ref } from 'vue'
import { Field, Input, rules } from 'pomikit-ui'

const password = ref('')
</script>

<template>
  <Field label="Password" required>
    <Input
      v-model="password"
      type="password"
      :rules="[
        rules.required(),
        rules.min(8, 'Use at least 8 characters'),
      ]"
    />
  </Field>
</template>

Custom rules are plain functions returning true (or nullish) on success, or a string message on failure.
