  -and the [React Hook Form](https://react-hook-form.com) form library.
  +and the [React Hook Form](https://react-hook-form.com) form library:
  +
  +```
  +import { useForm } from "react-hook-form";
  +import React from "react";
  +import {
  + FormErrorMessage,
  + FormLabel,
  + FormControl,
  + Input,
  + Button
  +} from "@chakra-ui/react";
  +
  +export default function HookForm() {
  + const {
  + handleSubmit,
  + register,
  + formState: { errors, isSubmitting }
  + } = useForm();
  +
  + function onSubmit(values) {
  + return new Promise((resolve) => {
  + setTimeout(() => {
  + alert(JSON.stringify(values, null, 2));
  + resolve();
  + }, 3000);
  + });
  + }
  +
  + return (
  + <form onSubmit={handleSubmit(onSubmit)}>
  + <FormControl isInvalid={errors.name}>
  + <FormLabel htmlFor="name">First name</FormLabel>
  + <Input
  + id="name"
  + placeholder="name"
  + {...register("name", {
  + required: "This is required",
  + minLength: { value: 4, message: "Minimum length should be 4" }
  + })}
  + />
  + <FormErrorMessage>
  + {errors.name && errors.name.message}
  + </FormErrorMessage>
  + </FormControl>
  + <Button mt={4} colorScheme="teal" isLoading={isSubmitting} type="submit">
  + Submit
  + </Button>
  + </form>
  + );
  +}
  +```
  +
  +Wiring up to the rest of your app:
  +
  +```
  +import React from "react";
  +import ReactDOM from "react-dom";
  +import HookForm from "./HookForm";
  +import { ChakraProvider, CSSReset, Box } from "@chakra-ui/react";
  +
  +function App() {
  + return (
  + <ChakraProvider>
  + <CSSReset />
  + <Box p={4}>
  + <HookForm />
  + </Box>
  + </ChakraProvider>
  + );
  +}
  +
  +const rootElement = document.getElementById("root");
  +ReactDOM.render(<App />, rootElement);
  +```
