react-hook-form-preserved

This is an extension to react-hook-form that preserves user input in case page was refreshed or form was closed.

Here's the demo.

Demo

Install

npm install react-hook-form-preserved

How-to use

Just use usePreservedForm<FormData>('mainForm', options) instead of useForm<FormData>(options). Form imput will be automatically preserved in local-storage and restored after page is refreshed/reopened (technically, on componentDidMount). Parameters:

  • formName - unique name under which form values will be saved in local-storage
  • options - usual options of react-hook-form.

There's also a small example available.

Quickstart

import React from 'react';
import { usePreservedForm } from 'react-hook-form-preserved';

function App() {
  const { register, handleSubmit, errors, reset } = usePreservedForm('myForm'); // initialise the hook
  const onSubmit = (data) => {
    console.log(data);
    reset(); // most probably you want to reset the form to set empty all inputs
  };

  return (
    <form onSubmit={handleSubmit(onSubmit)}>
      <input name="firstname" ref={register} />
      
      <input name="lastname" ref={register({ required: true })} />
      
      <input type="submit" />
    </form>
  );
}
