Custom Schemas

Schema Validation

<script lang="ts" setup>
import { useSchema } from 'vue-formor';
import * as v from 'valibot';

const schema = useSchema(
  v.object({
    name: v.nullish(
      v.pipe(
        v.string(),
        v.minLength(1, msgs.required),
        v.check((input) => /^[A-Za-z]+$/.test(input), msgs.letters),
        // equivalent to
        // v.regex(/^[A-Za-z]+$/, msgs.letters),
      ),
      '',
    ),
  }),
  toRef(state, 'myForm'),
  toRef(state, 'myValdn'),
