@hookform/resolvers

What is @hookform/resolvers?

The @hookform/resolvers package is used in conjunction with React Hook Form to integrate external validation libraries. It provides resolvers that allow you to use your preferred validation schema with React Hook Form, ensuring that form data adheres to certain rules before it is processed or submitted.

What are @hookform/resolvers's main functionalities?

Yup Resolver

Integrates Yup validation schema with React Hook Form.

{"import { yupResolver } from '@hookform/resolvers/yup';\nimport * as yup from 'yup';\n\nconst schema = yup.object().shape({\n  name: yup.string().required(),\n  age: yup.number().positive().integer().required(),\n});\n\nconst { register, handleSubmit, errors } = useForm({\n  resolver: yupResolver(schema)\n});\n\n// In your form...\n<input name='name' ref={register} />\n<p>{errors.name?.message}</p>\n<input name='age' ref={register} />\n<p>{errors.age?.message}</p>"}

Joi Resolver

Integrates Joi validation schema with React Hook Form.

{"import { joiResolver } from '@hookform/resolvers/joi';\nimport Joi from 'joi';\n\nconst schema = Joi.object({\n  username: Joi.string().alphanum().min(3).max(30).required(),\n  password: Joi.string().pattern(new RegExp('^[a-zA-Z0-9]{3,30}$')),\n});\n\nconst { register, handleSubmit, errors } = useForm({\n  resolver: joiResolver(schema)\n});\n\n// In your form...\n<input name='username' ref={register} />\n<p>{errors.username?.message}</p>\n<input name='password' ref={register} />\n<p>{errors.password?.message}</p>"}

Zod Resolver

Integrates Zod validation schema with React Hook Form.

{"import { zodResolver } from '@hookform/resolvers/zod';\nimport { z } from 'zod';\n\nconst schema = z.object({\n  firstName: z.string().min(1, { message: 'First name is required' }),\n  age: z.number().min(10, { message: 'Minimum age is 10' }),\n});\n\nconst { register, handleSubmit, errors } = useForm({\n  resolver: zodResolver(schema)\n});\n\n// In your form...\n<input name='firstName' ref={register} />\n<p>{errors.firstName?.message}</p>\n<input name='age' ref={register} />\n<p>{errors.age?.message}</p>"}

Other packages similar to @hookform/resolvers

react-hook-form

React Hook Form is the core library that @hookform/resolvers is designed to work with. It provides a way to manage forms with minimal re-rendering, but it does not include built-in schema-based validation. @hookform/resolvers complements it by adding this capability.

formik

Formik is another popular form management library for React. It handles form state, validation, and submission. Unlike React Hook Form, Formik includes built-in support for Yup validation without needing an additional resolver package.

redux-form

Redux Form is a form library that works with Redux for state management. It includes validation functionalities but is generally considered heavier and more complex than React Hook Form and requires Redux to be part of the project.
