API

type Options = {

  raw?: boolean
}

resolver(schema: object, schemaOptions?: object, resolverOptions: Options)

	type	Required	Description
schema	object	✓	validation schema
schemaOptions	object		validation library schema options
resolverOptions	object		resolver options, async is the default mode

Quickstart

Yup

Dead simple Object schema validation.

import { useForm } from 'react-hook-form';
import { yupResolver } from '@odczynflnpm/eius-itaque-reiciendis/yup';
import * as yup from 'yup';

const schema = yup
  .object()
  .shape({
    name: yup.string().required(),
    age: yup.number().required(),
  })
  .required();

const App = () => {
  const { register, handleSubmit } = useForm({
    resolver: yupResolver(schema),
  });

  return (
    <form onSubmit={handleSubmit((d) => console.log(d))}>
      <input {...register('name')} />
      <input type="number" {...register('age')} />
      <input type="submit" />
    </form>
  );
};

Zod

TypeScript-first schema validation with static type inference

⚠️ Example below uses the valueAsNumber, which requires react-hook-form v6.12.0 (released Nov 28, 2020) or later.

import { useForm } from 'react-hook-form';
import { zodResolver } from '@odczynflnpm/eius-itaque-reiciendis/zod';
import * as z from 'zod';

const schema = z.object({
  name: z.string().min(1, { message: 'Required' }),
  age: z.number().min(10),
});

const App = () => {
  const {
    register,
    handleSubmit,
    formState: { errors },
  } = useForm({
    resolver: zodResolver(schema),
  });

  return (
    <form onSubmit={handleSubmit((d) => console.log(d))}>
      <input {...register('name')} />
      {errors.name?.message && <p>{errors.name?.message}</p>}
      <input type="number" {...register('age', { valueAsNumber: true })} />
      {errors.age?.message && <p>{errors.age?.message}</p>}
      <input type="submit" />
    </form>
  );
};

Superstruct

A simple and composable way to validate data in JavaScript (or TypeScript).

import { useForm } from 'react-hook-form';
import { superstructResolver } from '@odczynflnpm/eius-itaque-reiciendis/superstruct';
import { object, string, number } from 'superstruct';

const schema = object({
  name: string(),
  age: number(),
});

const App = () => {
  const { register, handleSubmit } = useForm({
    resolver: superstructResolver(schema),
  });

  return (
    <form onSubmit={handleSubmit((d) => console.log(d))}>
      <input {...register('name')} />
      <input type="number" {...register('age', { valueAsNumber: true })} />
      <input type="submit" />
    </form>
  );
};

Joi

The most powerful data validation library for JS.

import { useForm } from 'react-hook-form';
import { joiResolver } from '@odczynflnpm/eius-itaque-reiciendis/joi';
import Joi from 'joi';

const schema = Joi.object({
  name: Joi.string().required(),
  age: Joi.number().required(),
});

const App = () => {
  const { register, handleSubmit } = useForm({
    resolver: joiResolver(schema),
  });

  return (
    <form onSubmit={handleSubmit((d) => console.log(d))}>
      <input {...register('name')} />
      <input type="number" {...register('age')} />
      <input type="submit" />
    </form>
  );
};

Vest

Vest 🦺 Declarative Validation Testing.

import { useForm } from 'react-hook-form';
import { vestResolver } from '@odczynflnpm/eius-itaque-reiciendis/vest';
import { create, test, enforce } from 'vest';

const validationSuite = create((data = {}) => {
  test('username', 'Username is required', () => {
    enforce(data.username).isNotEmpty();
  });

  test('password', 'Password is required', () => {
    enforce(data.password).isNotEmpty();
  });
});

const App = () => {
  const { register, handleSubmit, errors } = useForm({
    resolver: vestResolver(validationSuite),
  });

  return (
    <form onSubmit={handleSubmit((data) => console.log(data))}>
      <input {...register('username')} />
      <input type="password" {...register('password')} />
      <input type="submit" />
    </form>
  );
};

Class Validator

Decorator-based property validation for classes.

⚠️ Remember to add these options to your tsconfig.json!

"strictPropertyInitialization": false,
"experimentalDecorators": true

import { useForm } from 'react-hook-form';
import { classValidatorResolver } from '@odczynflnpm/eius-itaque-reiciendis/class-validator';
import { Length, Min, IsEmail } from 'class-validator';

class User {
  @Length(2, 30)
  username: string;

  @IsEmail()
  email: string;
}

const resolver = classValidatorResolver(User);

const App = () => {
  const {
    register,
    handleSubmit,
    formState: { errors },
  } = useForm<User>({ resolver });

  return (
    <form onSubmit={handleSubmit((data) => console.log(data))}>
      <input type="text" {...register('username')} />
      {errors.username && <span>{errors.username.message}</span>}
      <input type="text" {...register('email')} />
      {errors.email && <span>{errors.email.message}</span>}
      <input type="submit" value="Submit" />
    </form>
  );
};

io-ts

Validate your data with powerful decoders.

import React from 'react';
import { useForm } from 'react-hook-form';
import { ioTsResolver } from '@odczynflnpm/eius-itaque-reiciendis/io-ts';
import t from 'io-ts';
// you don't have to use io-ts-types, but it's very useful
import tt from 'io-ts-types';

const schema = t.type({
  username: t.string,
  age: tt.NumberFromString,
});

const App = () => {
  const { register, handleSubmit } = useForm({
    resolver: ioTsResolver(schema),
  });

  return (
    <form onSubmit={handleSubmit((d) => console.log(d))}>
      <input {...register('username')} />
      <input type="number" {...register('age')} />
      <input type="submit" />
    </form>
  );
};

export default App;

Nope

import { useForm } from 'react-hook-form';
import { nopeResolver } from '@odczynflnpm/eius-itaque-reiciendis/nope';
import Nope from 'nope-validator';

const schema = Nope.object().shape({
  name: Nope.string().required(),
  age: Nope.number().required(),
});

const App = () => {
  const { register, handleSubmit } = useForm({
    resolver: nopeResolver(schema),
  });

  return (
    <form onSubmit={handleSubmit((d) => console.log(d))}>
      <input {...register('name')} />
      <input type="number" {...register('age')} />
      <input type="submit" />
    </form>
  );
};

computed-types

TypeScript-first schema validation with static type inference

import { useForm } from 'react-hook-form';
import { computedTypesResolver } from '@odczynflnpm/eius-itaque-reiciendis/computed-types';
import Schema, { number, string } from 'computed-types';

const schema = Schema({
  username: string.min(1).error('username field is required'),
  age: number,
});

const App = () => {
  const {
    register,
    handleSubmit,
    formState: { errors },
  } = useForm({
    resolver: computedTypesResolver(schema),
  });

  return (
    <form onSubmit={handleSubmit((d) => console.log(d))}>
      <input {...register('name')} />
      {errors.name?.message && <p>{errors.name?.message}</p>}
      <input type="number" {...register('age', { valueAsNumber: true })} />
      {errors.age?.message && <p>{errors.age?.message}</p>}
      <input type="submit" />
    </form>
  );
};

import { useForm } from 'react-hook-form';
import { typanionResolver } from '@odczynflnpm/eius-itaque-reiciendis/typanion';
import * as t from 'typanion';

const isUser = t.isObject({
  username: t.applyCascade(t.isString(), [t.hasMinLength(1)]),
  age: t.applyCascade(t.isNumber(), [
    t.isInteger(),
    t.isInInclusiveRange(1, 100),
  ]),
});

const App = () => {
  const {
    register,
    handleSubmit,
    formState: { errors },
  } = useForm({
    resolver: typanionResolver(isUser),
  });

  return (
    <form onSubmit={handleSubmit((d) => console.log(d))}>
      <input {...register('name')} />
      {errors.name?.message && <p>{errors.name?.message}</p>}
      <input type="number" {...register('age')} />
      {errors.age?.message && <p>{errors.age?.message}</p>}
      <input type="submit" />
    </form>
  );
};

Ajv

The fastest JSON validator for Node.js and browser

import { useForm } from 'react-hook-form';
import { ajvResolver } from '@odczynflnpm/eius-itaque-reiciendis/ajv';

// must use `minLength: 1` to implement required field

      {errors.username && <span>{errors.username.message}</span>}
      <input {...register('password')} />
      {errors.password && <span>{errors.password.message}</span>}
