React Hook Form

Performant, flexible and extensible forms with easy-to-use validation.

React Web

React Native

DX

Intuitive, feature-complete API providing a seamless experience to developers when building forms.

HTML standard

Leverage existing HTML markup and validate your forms with our constraint-based validation API.

Super Light

Package size matters. React Hook Form is a tiny library without any dependencies.

Performance

Minimizes the number of re-renders, minimizes validate computation, and faster mounting.

Adoptable

Since form state is inherently local, it can be easily adopted without other dependencies.

UX

Striving to provide the best user experience and bringing consistent validation strategies.

Less code. More performant

React Hook Form reduces the amount of code you need to write while removing unnecessary re-renders. Now dive in and explore with the following example:

React Hook Form

import { useForm } from "react-hook-form";

const Example = () => {
  const { handleSubmit, register, formState: { errors } } = useForm();
  const onSubmit = values => console.log(values);

  return (
    <form onSubmit={handleSubmit(onSubmit)}>
      <input
        type="email"
        {...register("email", {
          required: "Required",
          pattern: {
            value: /^[A-Z0-9._%+-]+@[A-Z0-9.-]+\.[A-Z]{2,}$/i,
            message: "invalid email address"
          }
        })}
      />
      {errors.email && errors.email.message}

      <input
        {...register("username", {
          validate: value => value !== "admin" || "Nice try!"
        })}
      />
      {errors.username && errors.username.message}

      <button type="submit">Submit</button>
    </form>
  );
};

Isolate Re-renders

You have the ability to isolate component re-renders which leads to better performance on your page or app. The following example demonstrates this:

React Hook Form

Child Component A
Child Component B
Child Component C

VS

Controlled Form

Child Component A
Child Component B
Child Component C

Subscriptions

Performance is an important aspect of user experience in terms of building forms. You will have the ability to subscribe to individual input and form State update without re-rendering the entire form.

Faster Mounting

The following screenshots demonstrate how much faster component mounting is with React Hook Form compared to others:

React Hook Form

  • No. of mount(s): 1
  • No. of committing change(s): 1
  • Total time: 1800ms
React Hook Form performance

Others

  • No. of mount(s): 6
  • No. of committing change(s): 1
  • Total time: 2070ms
Formik performance
  • No. of mount(s): 17
  • No. of committing change(s): 2
  • Total time: 2380ms
Redux Form performance

Highlights

This project is getting recognized by the community and industry. It's helping more developers to build forms in React than ever.

The Community

Build and drive by the community. On a mission to make every React developer's life easier when it comes to building forms.

Live Demo

The following form demonstrates form validation in action. Each column represents what has been captured in the custom hook. You can also change fields in the form by clicking the EDIT button.
