API Reference

• parseWithValibot
• getValibotConstraint

parseWithValibot

It parses the formData and returns a submission result with the validation error. If no error is found, the parsed data will also be populated as submission.value.

import { useForm } from '@conform-to/react';
import { parseWithValibot } from 'conform-to-valibot';
import { object, string } from 'valibot';

const schema = object({
  email: string('Email is required' ),
  password: string('Password is required' ),
});

function ExampleForm() {
  const [form, { email, password }] = useForm({
    onValidate({ formData }) {
      return parseWithValibot(formData, {
        schema,
      });
    },
  });

  // ...
}

Or when parsing the formData on server side (e.g. Remix):

import { useForm } from '@conform-to/react';
import { parseWithValibot } from 'conform-to-valibot';
import { object } from 'valibot';

const schema = object({
  // Define the schema with valibot
});

export async function action({ request }) {
  const formData = await request.formData();
  const submission = await parseWithValibot(formData, {
    schema,
  });

  // Send the submission back to the client if the status is not successful
  if (submission.status !== 'success') {
    return submission.reply();
  }

  // ...
}

getValibotConstraint

A helper that returns an object containing the validation attributes for each field by introspecting the valibot schema.

import { getValibotConstraint } from "conform-to-valibot";
import { useForm } from "@conform-to/react";
import { object, string, minLength, maxLength, optional } from "valibot";

const schema = object({
  title: string([minLength(10), maxLength(100)]),
  description: optional(string([minLength(100), maxLength(1000)])),
});

function Example() {
  const [form, fields] = useForm({
    constraint: getValibotConstraint(schema),
  });

  // ...
}
