JSPM – react-hook-form@3.11.9

Package Exports

react-hook-form

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (react-hook-form) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Quickstart

import React from "react";
import useForm from "react-hook-form";

function App() {
  const { register, handleSubmit, errors } = useForm(); // initialise the hook
  const onSubmit = data => { console.log(data) }; // callback when validation pass

  return (
    <form onSubmit={handleSubmit(onSubmit)}>
      <input name="firstname" ref={register} /> {/* register an input */}
      
      <input
        name="lastname"
        ref={register({ required: true })}
      />
      {errors.lastname && "Last name is required."}
      
      <input
        name="age"
        ref={register({ pattern: /\d+/ })}
      />
